Emergency Locksmith Sidcup: why a front door suddenly won't open
Most people assume a door that won't open means a broken lock, but in Sidcup the cause is often simpler and the fix is cleaner than you would expect. On timber doors we frequently see swollen frames after wet weather, a nightlatch that has dropped on the snib, a seized mortice deadlock, or a key that has worn down so far it no longer catches the levers. On uPVC and composite doors the usual culprits are a misaligned keep, a handle that has started to sag, or a euro cylinder that is stiff and sticking.
When you call, we will talk you through a few safe checks first — whether a spare key is with a neighbour or family member, whether a back door, patio or French door is open, and exactly which type of lock you are dealing with. None of that involves forcing anything or risking damage, and sometimes it saves a visit entirely. If entry is needed, our aim is always a non-destructive technique that leaves your existing lock working afterwards.
Knowing what to do when you are locked out of your house starts with staying calm and not kicking or shouldering the door, which usually causes far more expensive damage than the lockout itself. Keep away from the glass panels on a composite or uPVC door, and give us a ring. We will confirm the likely fault, the type of lock involved and a clear up-front price before we set off.
