The Olympiades towers
In the towers, the front door often still has its original three-point lock: we change its set of cylinders and hand you all the new keys.

A bunch of keys lost on the métro, a bag stolen with your ID, keys still held by a former flatmate: in the 13th, we replace the cylinder or the whole lock, depending on the risk and the condition of the lock. Price given before we come out, 24/7.

Keys lost with nothing to link them to your address do not carry the same risk as keys stolen with your ID. In the first case, the change can wait for an appointment; in the second, it is best not to leave it overnight.
The cylinder is the part the key goes into; the lock is the mechanism that bolts the door. After losing your keys, changing the cylinder is enough in most cases: the door stays as it is, and only the old keys become useless.
The whole lock is replaced when it is worn, when it has been forced, or when you want a higher level of security, such as an A2P-certified lock. On site, we show you the condition of the lock before suggesting anything. The full picture is on our lock change in Paris page.

It is advisable, especially if your ID went missing with them: insurers often ask for proof of the police report before covering the lock change. Also keep the invoice we give you.
It depends on the policy: some cover lost or stolen keys, others only theft involving a break-in. Reread your policy or call your insurer before the job.
No: the building’s fobs and remote controls are handled by the building manager (syndic) or the caretaker, who can deactivate the old one and programme a new one. Let them know quickly; we take care of the door to your home.
A high-security euro profile cylinder starts at €90 incl. VAT, for a single-point lock. For a three-point lock, the table above gives the price of compatible cylinder sets by brand.
From the towers to the houses on the Butte, the cylinder to be changed is not the same: here is what we find most often in each area.
In the towers, the front door often still has its original three-point lock: we change its set of cylinders and hand you all the new keys.
Buildings completed since the 2000s, recent front doors: the cylinder is changed in a few simple steps, without touching the door.
Houses and small buildings with locks that are sometimes very old: when the cylinder is no longer made, we replace the entire lock with a current model.
Stone buildings from the early 1900s: surface-mounted locks and cylinders of every brand, which we identify from a photo before coming out.
