Correct sizing
We measure the current cylinder so the new one sits flush with the escutcheon, not protruding.
🔑 The most common fix
Cylinder replacement
The cylinder (or barrel) is the part the key goes into. Changing it fully renews your door’s security at the lowest cost: new keys, and the old ones stop working instantly.

Cylinder replacement
Fast, affordable and final
On most doors, replacing the cylinder takes minutes: the old barrel is removed and the new one fitted with its keys. No building work, the lock is untouched and the door works the same… but with keys only you have.
What matters is getting the size right (cylinders are measured in two halves from the cam, e.g. 30×30) and the security level. A cylinder protruding from the escutcheon, for instance, is a gift to an intruder: we make sure the new one sits flush.
- Lost or stolen keys.
- Moving into a new or rented home.
- A stiff, jammed or worn cylinder.
- Keying alike: one key for several doors.

How long does it take to change a cylinder?
With the right size, 10 to 20 minutes on most doors. We carry cylinders in the usual sizes, so it’s usually solved in a single visit.
Which cylinder do you recommend?
For a front door, at least an anti-bump cylinder with a protected key. For stores or interiors a standard one may do. Detail at security locks and ranges at cylinder replacement cost.
New cylinder or new lock?
If the door closes fine and you only want to void the old keys, a cylinder. If the mechanism fails or you want more locking points, consider a lock replacement.
