When should the cylinder be replaced?
Lost or stolen keys
The essential reflex: new keys, a new cylinder, and no one else gets in.
Moving in
Former occupants, tradespeople, the property manager: too many copies in circulation. Change the cylinder as soon as you move in.
Key broken in the cylinder
Extraction of the fragment where possible, replacement if the mechanism is marked.
Faulty cylinder
It spins without engaging, sticks or rejects the key: signs that the end is near.
Security upgrade
Swapping a standard cylinder for a pick-resistant model changes everything, on a modest budget.
Keyed-alike systems
Keyed-alike cylinders: one single key for the front door, the cellar and the garage.
Cylinder or complete lock?
If the lock mechanism is in good condition, replacing the cylinder alone is enough in most cases: it is quick and economical. If the lock itself is worn or offers little security, a full lock replacement is the better choice. Our assessment gives you an honest answer, and you approve the quote before any work.

Our high-security cylinders
We fit cylinders that are pick-resistant, drill-resistant and snap-resistant, protected against bumping, with keys protected by an ownership card: no copy can be made without your consent. To learn more about protection levels, see our page on A2P-certified high-security locks.
