High-security cylinders: your questions
Another question? Call us, even at night.
Why change only the cylinder?
After losing keys or moving in, changing the cylinder is usually enough: the lock stays in place and you get new keys with their card of ownership.
How do I know which cylinder fits my lock?
The cylinder depends on the make and model of the lock, and its dimensions are measured on the door. Send us a photo of the lock, from the landing and from inside: we tell you the right cylinder and its price.
What is the card of ownership for?
It proves you own the keys: without it, nobody can copy them. Keep it somewhere safe, away from the keys.
Does the price include fitting?
The price on the product page is for the cylinder. A standard European cylinder is replaced from €90, fitting included; for a compatible cylinder, we give you the fitted price before any work.
