What is a locksmith?

Yes, here at Barnet Lock we specialise in both residential and commercial locksmiths services in Watford and the surrounding areas. It doesn’t matter what type of key you require cutting, we can help!

What should I do if my key breaks in the lock?

It is of course very tempting to fiddle with the broken key in the hope that you can salvage it yourself, but we do advise against it. More damage can be caused. It is also important that you keep the other part of the key safe so that the locksmith can identify the problem and organise a replacement for you.

Should I change the locks if I lose my keys?

Yes. Even though it is highly unlikely that somebody would find your keys and know where you live, we would always advise that you have your locks changed. It is better to be safe than sorry! If somebody accesses your property with the keys then you could lose out on any insurance claims.
