All in a Day’s Work for a locksmith

The variety we get here at Linacre Locksmiths is enormous. Many people think all locksmiths do is open locks, and maybe replace broken ones. While that is certainly part of our day to day job, there is plenty of other things we do.  Here are a couple of recent examples of the variety we get asked to deal with.

This still makes me laugh even after 14 years – the Fountains of Doom. Gearbox had failed due to stress caused by misalignment of this upvc door – it had dropped due to the weight of water within and was half an inch out at top.  This meant the rollers didn’t engage correctly with the keeps on the frame so more and more force was being applied to the lifting the handles up and so eventually the internals of the mechanism gave way, causing the lock to jam and not be able to be opened.  After opening the door i started to remove the screws on the strip, ultimately reaching the last two, and lo and behold, jets of water came streaming out. Took a good 10 minutes to drain although was still still dripping slightly when I left half an hour later.

Customer was going to speak to a upvc repair company to get the seals replaced and drain holes cleared.

Another of this week’s jobs saw a customer try his hand at doing it himself. He knew his upvc door gearbox had broken in his front door and had attempted a DIY removal and replacement. He had removed the entire mechanism from the door, and opened up the lockcase and diagnosed which small part had broken. Put it all back together, measured to order a replacement gearbox, refitted the mechanism back in the door, shut door then couldn’t re-open. He tried all sorts of drill bits to figure out why it wouldn’t open. Drilling into the latchbolt assembly didn’t help him of course. He had to call a locksmith in the end (me) to open door and then fit his eBay ordered lock.

Seeing this sort of variety certainly keeps me entertained and makes an occasional change from the humdrum. And it is what makes this job so enjoyable.  I wouldn’t want to do anything else!


Yale nightlatch – safety without compromising security

Many main entrance doors to a block of flats, for example, have a basic Yale nightlatch or similar fitted. While this is convenient for the tenants it fails to meet two criteria…

Meeting insurance approved security levels

Allowing for easy fire escape in emergencies

A standard Yale type nightlatch arrangement is easy to use but also vulnerable to being picked/slipped or bypassed by people who should not be entering (non-keyholders). If you want to improve the security of the lock a BS3621 nightlatch can be fitted. It features an armoured cylinder escutcheon and automatically deadlocking latchbolt when the door is closed. However these nightlatches also have the ability to have the inner handle deadlocked with the key, stopping it from being operated if someone smashes the glass.

This is fine for a domestic property but totally unsuitable for a communal entrance door.

The reason is that in the event of an emergency the residents need to escape quickly. It can potentially be fatal if someone has locked the inner handle, as without the key it cannot be unlocked and therefore allow the lock/door to be opened and escape made. You cannot have the residents being forced to go back into their smoke filled flat, for example, to find a key in their panic.

So Yale make a version specifically to cater for this requirement. Depending on the size of the lock it is called the PBS3 or PBS4.  The British Standards these locks adhere to is BS8621 (as opposed to BS3621 for the lockable version). Here is a picture of a PBS4 fitted by Linacre locksmiths.

The inner handle has no keyway so cannot be deadlocked – fire escape regulations will always override security. The safe evacuation of residents is always the first concern.

So if you are concerned what is fitted to your own communal doorway, or if a landlord looking to check you have the right lock in place, give Linacre Locksmiths a call and we can give the correct advice.

Masterkeying and keying alike lock cylinders explained

A very useful system is masterkeying and keying alike lock cylinders, where multiple locks are required to be operated with the minimum of keys. On a simple level a homeowner may want their front and back door locks to be keyed alike to save having two different keys. This means that both locks are keyed alike, and share the same key, so one key can operate either door. Many upvc french doors (double doors) have a keyed alike cylinder in each door. Linacre Locksmiths often get asked to do this for homeowners who need locks changed due to lost or stolen keys for example.

However this advantage of keying alike locks is also useful to landlords who may have 3 or 4 bedrooms let out to students for example. Each student wants to lock their own door of course and also have a key to the entrance doors. Which means normally one key for front door, one key for back door and one key for their room. Three keys. Why not just have one! Here is an example of a simple masterkeying and keying alike lock suite.

masteryed lock cylinders
a simple lock suite of 4 bedroom locks

The house has four bedroom doors, with front and back entrance doors. These entrance doors have been keyed alike (the same). As can be seen, the landlord has 3 master keys which can operate every lock in the house. But the students have their own keys which can do only their own bedroom but also either entrance door.

A similar suite is in the following picture. However in this instance the landlord also wanted 3 keys that just operate the entrance doors only. This is so they can give a tradesperson one of these keys (for instance a gas boiler service engineer) so they can enter the property to do the work but not be able to access any bedrooms. Again the entrance doors are keyed alike, and again the tenant has a key that does their own room and entrance doors but no other. The landlord has master keys which can operate every door.

These are simple examples of course but are ideal for landlords with a house of multiple occupancy. There are many higher levels of masterkeying and keying alike such as those found in hotels for example. Locks can be grouped into sub-groups each with their own master keys, and with a set of grand master keys to open them all.

Linacre Locksmiths can provide this service and the benefits to homeowners and landlords is obvious.

The importance of good security for your upvc doors

The advantages and security of upvc doors are obvious and are installed on millions of properties throughout the country. The sense of security we get when we lift the handle up to lock and all those multiple locking points come into play. We feel secure. But just how secure are they really?

Every locksmith will tell you that the weakest point of every upvc door is the cylinder. The locking mechanism can throw out a hundred locking points such as hooks and deadbolts, but if the cylinder gets compromised then the handle goes down and the door opens. These upvc doors have been around for a few decades now and many still have the same original euro cylinders fitted. Many home owners pay little attention to security especially if they have never been broken into before. Criminals however are always looking for ways to defeat locks and break into properties quickly. And so lock snapping is on the rise as a preferred method of entry. The most basic of tools are required and is a fairly quiet method of gaining entry. Here is a picture of a burglary we saw yesterday where such a method was used…

As you can see the burglar destroyed the handle and cylinder in order to remove it and access the internals of the locking mechanism to unlock the door. The burglar then moved through the conservatory and onto the upvc sliding door.  If you think they are more secure think again…

Full entry gained to house in probably less than 5 minutes.

So what can the home owner do to prevent this? Well the answer is simple. There are higher standards these days for cylinders which mean they can be tested against many forms of attack, such as drilling, snapping, plug pulling and simple lock picking. Most euro cylinders on most homes are standard 5 or 6 pin cylinders not meeting any specific testing criteria (mainly because these tests came out many years after their original installation). More recent cylinders have appeared which carry the British Standard BS kitemark logo. And now they also carry a ‘star’ rating.

In general terms there are three ‘classes’ of euro cylinders. The countless thousands fitted to thousands of doors, some 10 or 20+ years old which carry no specific standard, or a basic level one. Then there are the more recent, more tested, more secure ones. Ones which carry the BS kitemark logo and also show a single star, or the higher class of 3 stars. Guess which is the best, most secure version!

When choosing a cylinder why compromise just to save a few quid? Think how much more you could lose to a burglar. When choosing to replace your cylinders there are two main criteria to look for:-

The SS312 rated locks are the highest possible standard you can currently get and these locks have been tested using all known burglar techniques, also employing the very tools the burglars use.

The TS007:2012 3 star cylinder is also a very high rating one and has passed anti snapping tests.

Be aware that there are kitemark TS007 cylinders with only 1 star on them. This doesn’t mean they are poor locks, but just that they have not necessarily been tested for their anti-snap capability. So what brands carry the top SS312 rating?  Here are a few to look for…

  • ABS Mk3
  • ERA Fortress
  • UAP Kinetica 3 Star
  • Avocet ATK
  • Ultion (Brisant)

Many brands offer the TS007 3 star and are also very good…

  • Yale
  • Asec Kite
  • GeGe
  • BKS
  • Iseo

and many others.

In truth there is no real point in fitting a 1 star euro cylinder when for a few pounds extra you can get a 3 star one and have that important peace of mind. Cost wise each 3 star cylinder is around £45 but surely that is worth spending when it comes to protecting your home, valuables and family. Increase your security and reduce risk.

Ask Linacre Locksmiths for advice and recommendations, and we can order and fit them for you.

Small locksmith competing for advertising space

How can i compete with the advertising budget of national call centres?

As the title suggests, can a small one man band locksmith company compete with big national call centre operations?  Well in terms of advertising revenue spend then the answer is of course no. Type Norwich locksmiths into any search engine and the first results are always major companies. Now they pretend to be local, on your doorstep almost. But in reality they are based in Birmingham, Dorset, Essex, Manchester etc. Their adverts have ‘local’ sounding numbers but isn’t it a little strange that whoever answers the phone has a midlands, Mancunian or Essex accent! Can you also hear chatter in the background, perhaps other people on the phones? Welcome to the world of the fake local companies.

Open up the Norwich yellow pages under locksmiths and it is packed with 1/4 and 1/2 page adverts trying to impress.  Lots of towns listed alongside corresponding ‘local’ sounding numbers.  Want some fun if bored?  Dial each number in turn.  Chances are you get the same couple of individuals who answer (in their non-local accent). Why do they want to know the advert ref number – small number within corner of advert?  So they can see which book you got it from. And many of these different looking ads are actually the same company. Check the tiny printed addresses. Whole pages seem to have 4 different ads for example, but are actually the same call centre. They quote a high figure (plus vat) but if you have never used a locksmith before you may not know how extortionate it is. And they make sure to take your card details before anyone has even been booked to attend.

As for the actual people who attend (the sub-contractors)……. well i leave that discussion for another time. Along with photographic evidence of some of their handy work perhaps.

So because of the high charges they make the customers pay, and therefore the high advertising budget they can afford to spend, nationwide, it is really difficult to compete directly with them. So this is where reputation and word of mouth comes into play and is much more valuable to a sole trader locksmith. Check out the reviews of Linacre Locksmiths from all over the web. For comparison check in detail the reviews of the national companies. See the difference? Traditional advertising in the paper version of the Yellow Pages etc is dying out. Already over the last 5 years that book has shrunk to a quarter of it’s original size. And since dominated by the nationals it is quite easy to let them have it and scrap amongst themselves. These days the customer is far more savvy about researching first, using smartphones and desktops etc.

So the only way to beat these companies is to do a high standard of work, at a very reasonable price, and work hard. No short cuts. Something Linacre Locksmiths are proud to do. Check us out here..

Linacre Locksmiths can cover most lock scenarios

Although many jobs we locksmiths do are fairly routine and commonplace, occasionally we get to do rare stuff too. It is quite common for many properties, especially those in more rural areas, to have very thin wooden doors.  These are typically at the rear of the property.  The thinness of the doors however means that traditional mortice locks cannot be fitted, of it they can then only very basic 2 lever ones due to the thin width of the lock case itself.  But many insurance companies these days insist on 5 lever locks (and often also conforming to BS3621 insurance standards).  This is the door we were called out to recently…

Although the options in the marketplace are limited there is a way of fitting a BS3621 5 lever deadlock to the door.  Not only that but a Chubb one too which is about as good as you can get domestically. A specially made rim lock box is fitted to the back of the door at ‘kick height’ that cannot be removed from outside and the deadlock is fixed into the box. The keep plate/box is added to the frame with reinforcing bolts too for extra strength.  We also added a kickstop (also known as a London Bar) to reinforce the staple box on the frame even further.  Here is a picture of the lock fitted…

A rather amusing upvc door issue us locksmiths occasionally encounter

Not for the first time have I seen this, though it is rare.  Linacre Locksmiths were called out to replace a full length multipoint locking strip today by a customer who had complained that her door had ‘dropped’ and was difficult to lock for a while.  Over time this had meant the mechanism was getting forced harder and harder to operate. The lock eventually failed. I undid screws from top downwards and when I was within 2 feet from the bottom, on removing the screw a jet of water shot out.


This jet continued for about 5 mins, then as I work down to remove the lower screws more water came out. Must have been a gallon in the door. No wonder it had dropped with all that extra weight.

This can happen with outward opening doors, especially old ones, as rain water can seep into the old shrunken rubber seals and enter door cavity. Normally there are drain holes at the bottom of the doors to allow this water to escape but over time they get clogged with dirt, moss etc and bung the holes up.

So if your door feels ‘heavy’, or if it seems to have dropped excessively then maybe yours too has water trapped.  Check any visible drainage holes and clear out any debris. That includes drainage holes in the threshold (sill) too. Of course, other causes can result in doors misaligning and locking points not engaging with their keeps on the frame correctly, leading to stress damage.

Just give us a call to resolve and lock issues you have, and hopefully prevent an expensive replacement of parts.

Buy cheap, pay twice. Always use a locksmith rather than a cheap handyman

Not an example of my work but I saw this on a customer’s front door today and thought I would share. Obviously the original multipoint locking system had failed. But rather than source and fit a direct replacement, the handyman (or cowboy) that did this used a completely unsuitable mechanism as an alternative. The mech he fitted was for a upvc door not a wooden one, so his mech had rollers that stuck out proud from the door edge.  No bother for this intrepid workman. He just hacked out pieces of the frame so the rollers could enter and the door could close. The full length keep plate is a right mess and it is a struggle to raise the handles fully due to all the misalignment between mech rollers/hook bolts and the slots in the keep. Due to the differences in this mechanism and the original he also had to fit new handles.  But because the backset is different, the new handles do not quite cover the original handle screw holes and euro profile hole in the door.

I dread to think what the landlord paid his handyman for this poor effort, but if he had called me then job would have been done right using the right parts and without any damage to frame.

Want to be a locksmith in just two days?

Do you want to be a locksmith? You’ve seen it in the movies, a quick 2 second fiddle with a lock and hey presto they are in!  You have seen the two day courses being offered on eBay etc to become a locksmith, promising high incomes for very little outlay. So you think why not give locksmithing a bash – after all, how hard can it be?

I started Linacre Locksmiths over 11 years ago and can say that in all that time only around 10% of my work involves lockouts. Most of the work is either remedial work – fixing broken locks, adjusting upvc doors, rekeying locks etc – or replacing or fresh fitting various locks. The trouble is that if someone gets locked out then a professional locksmith comes out and can indeed literally get them back in their house in a couple of minutes sometimes.  So they think ‘wow, easy money. I could do that!’

You search for how to become a locksmith and suddenly eBay sellers and others offer to train you in two or three days. They might ‘train’ you in a rented office, or a small workshop on an industrial unit. You will be taught how to pick basic cylinders and mortice locks. No point in the ‘trainer’ using high security locks like you might find in the real world that you cannot open. After all, he promised you it is easy, so the locks will be primed to almost fall open (like the movies).  Then comes the sting. You can’t just head off into the locksmithing world without the right tools can you!  You are sold cheap imported poor quality tools, some of which you will never need, some do not even work properly, at vastly inflated prices. You don’t know any different so buy them. So after 2/3 days you are £2000 down and armed with poor knowledge and poor equipment. And all you can hope to do are simple lockouts, which as I mentioned earlier only account for 10% of an average locksmiths workload.

To be serious about being a locksmith you need substantial initial investment and proper training from well researched training companies. You need to be prepared to make a loss for the first year at least. And I haven’t even touched on how you actually get your name out there and attract customers!

At least here at Linacre Locksmiths you can be sure we have done it right!
