A lost key, a forced lock, a new occupant: replacing a mailbox lock is a quick job that keeps your mail out of anyone else's hands.
Price: from €110 incl. VAT. The exact price is given on the phone and confirmed in a written quote before any work. Day, evening and night prices
A lock that fits your mailbox
Building mailboxes use standardized locks. We identify the model and fit a compatible lock, supplied with its keys.
Opening without damage
If you no longer have a key, we open the mailbox without damaging the flap, then replace the lock.
What about your other locks?
If you lost your whole key ring, think about your front-door cylinder and your cellar too: we can handle everything in a single visit.
