The key goes in but won't turn, the handle resists, the door won't lock anymore: a jammed lock can keep you out, keep you in, or stop you from securing your apartment when you leave. Our locksmith finds the cause and repairs the mechanism whenever possible, without selling you a new lock you don't need.
Price: from €180 incl. VAT. The exact price is given on the phone and confirmed in a written quote before any work. Day, evening and night prices
What causes a lock to jam?
Most often: a cylinder clogged with dust or the wrong lubricant, a worn or slightly bent key, a door that has dropped so the bolt rubs against the strike plate, a broken spring inside the lock case, or a loose rod on a multi-point lock. In older buildings, changes in humidity also make wooden doors swell and shift.
Our repair, step by step
If you are locked out, we open the door first. The locksmith then takes the mechanism apart, shows you the faulty part and suggests the right repair: cleaning, adjusting the strike plate, replacing a spring or, if the cylinder is worn out, fitting a new one. Common parts are carried in the van so the job can be finished the same day.
Keeping your lock smooth
Once a year, a little dry lubricant (graphite or PTFE) in the keyway is enough. Avoid cooking oil and greasy sprays, which trap dust. If your door rubs or needs lifting to close, have the hinges adjusted: it is often the hidden cause of a bolt that sticks.

Frequently asked questions
The key spins without catching: is it serious?
It is usually a broken key bit or a broken cam in the cylinder. Don't force it: we open the door and replace only the faulty part.
Can a 3-point lock be repaired without replacing everything?
Yes, in most cases. We replace only the lock case, rod or cylinder concerned, not the whole system.
Will my insurance cover the repair?
It depends on your policy and on the cause (wear or attempted break-in). We give you a detailed invoice to send to your insurer.
