The work

- Full fitting and adjustment
- Key sets handed over
When to call us
- You're moving in: you don't know how many key sets are still out there.
- A key set has been lost or stolen, especially if it carried an address.
- The key catches, the cylinder is seizing, or the lock has already been forced in an attempt.

Frequently asked questions
Cylinder or complete lock — what's the difference?
The cylinder (barrel) is the part the key turns in; it can be replaced on its own if the rest of the mechanism is sound. A complete lock includes the case and the bolt, and is needed if the mechanism itself is damaged.
Can my lock be changed without changing the model?
Yes. In most cases a compatible cylinder can be fitted without altering the existing lock, which keeps both the cost and the time on site down.
When should I change the lock after moving in?
Ideally before you move in, or as soon as possible afterwards, so you can be certain that no old key sets still in circulation give access to the property.
