Common questions

Will replacing the cylinder change my keys?

Yes — a new cylinder comes with new keys. The old keys will no longer work.

Can I have the same key for front and back?

Yes, keyed-alike cylinders are a small additional cost and very popular.

How long does it take?

Under 20 minutes per door on a standard UPVC or composite installation.

Do I need an anti-snap version?

If your door faces the street and you have UPVC, we strongly recommend TS007 3-star.
