My UPVC door won't lock properly — is this an emergency? +
A UPVC door that will not lock is a security risk and should be treated as urgent, especially overnight. The most common cause is a failed multipoint locking mechanism or a dropped door that has gone out of alignment. Do not force the handle as this can snap internal components. A locksmith can usually repair or replace the mechanism the same day.
Will the locksmith damage my door to get in? +
A skilled locksmith will almost always use non-destructive entry methods to open your door without causing any damage. Techniques include lock picking, bypass tools, and specialist equipment that preserve both the lock and the door. Drilling is a last resort, used only when the lock is very high security or has been tampered with. If drilling is necessary, the locksmith will explain this before proceeding.
What should I do if my key snaps in the lock? +
Do not try to extract a broken key with tweezers or pliers as you risk pushing it deeper into the mechanism. Avoid forcing another key in on top of the broken piece. A locksmith has specialist extraction tools that can remove the broken key without damaging the lock cylinder. In most cases the lock itself is unharmed and a new key can be cut.
What is a BS3621 lock and do I need one? +
BS3621 is the British Standard for thief-resistant locks. Most home insurance policies require BS3621-compliant locks on all external doors as a condition of cover. These locks are tested to resist common attack methods including picking, drilling and snapping. If your locks do not meet this standard, your insurer could reject a burglary claim.
What should I do after a burglary? +
Call the police first and do not touch anything until they have attended — disturbing the scene can compromise forensic evidence. Once the police have finished, call an emergency locksmith to secure all entry points. Most insurers require you to upgrade to BS3621 or insurance-approved locks after a break-in, so ask your locksmith about compliant options.
Do landlords have to change locks between tenants? +
There is no legal requirement in England and Wales for landlords to change locks between tenancies, but it is considered best practice and many letting agents insist on it. Tenants have a right to quiet enjoyment of the property, and landlords cannot enter without permission even if they hold a key. If you are a tenant concerned about security, you can request a lock change — the landlord should cover the cost.
