Mailbox Lock: Key Copy and Replacement
Lost mailbox key or broken lock? Key copying, replacement of standardised building mailbox locks and master key systems. A practical guide in Brussels.
5.0/5
It is the small locksmithing problem everyone postpones — until the day the mail piles up behind a little door that no longer opens. Lost mailbox key, lock spinning loose, a bank of boxes to replace in a building: here are the solutions, from the simplest to the most complete.
Lost key: copy first, replace second
If someone in the building or the family still has a copy, the fastest solution is key duplication — mailbox keys are part of our key duplication service, alongside building keys, badges and Vigik keys.
No key left in circulation? No need to force the little door: we replace the mailbox lock — most Brussels buildings use standardised locks whose common models we carry, and you leave with brand-new keys.
Broken or forced lock
A key spinning loose, a sticking cylinder, or a box forced after an unwanted visit to the hallway: the mechanism is replaced quickly and cheaply — one of our simplest interventions. The price is announced by phone before we travel, and the job can piggyback on another call-out in the building.
Property managers and condominiums: master key systems
For buildings, we create master key systems: a single resident key opens the front door, the garage and the mailbox — while the property manager keeps control of communal access. Handy at tenant turnover: one cylinder is replaced without touching the rest. See also our cylinder replacement service and our condominiums and property managers page.
In practice
Call 0495 205 400, with a photo of your box's lock if possible: we identify the model, announce the price, and come with the right mechanism. Free quote, invoice provided — including for property managers.
