Locks & cylinders — replacement, repair, high security

The lock is the keystone of your security — yet most Paris-region homes still run on the single-point lock fitted at construction, decades ago. Replacing, repairing and upgrading locks and cylinders is the heart of our trade, with one constant rule: sell you the right security level, not the most expensive one.

Choosing the right level

Three questions frame the choice. What is the real exposure — a fifth-floor flat behind a coded lobby is not a corner house or a ground floor. What does your insurance require — many French policies demand a 3-point or A2P lock above certain insured values; we fit the required grade and hand over the certificate. And what is the door itself worth — an excellent lock on a weak door protects nothing; when the leaf or frame is the weak link, we say so and talk armouring instead. We fit established brands only — Vachette, Bricard, Fichet, Picard, Héraclès, Abus, Mottura — because a no-name lock is an orphan the day it needs a part or a secure key copy. Smart locks? Real convenience for access management, fitted on a certified mechanical base — never instead of one.
