If the key sticks, the cylinder spins, the door will not lock cleanly or the barrel has failed, A&E Window Doctor can replace the cylinder and check the door alignment at the same visit.
A door barrel should be replaced when the cylinder is damaged, unreliable, insecure or no longer working smoothly with the lock mechanism. The team checks whether the fault is the barrel, the handle, the gearbox or the door alignment before fitting parts.
Many door lock problems start with hinge drop, weather movement or a misaligned keep. Replacing the cylinder without correcting that pressure can shorten the life of the new part, so the door is checked as a complete system.
Security upgrades
Where appropriate, the team can fit modern replacement cylinders and advise on practical security improvements for uPVC, composite, patio and French doors.
Key won't turn or spins, or you want to re-key for security.

Questions customers ask
Can you replace a door barrel without replacing the door?
Yes. If the door and lock mechanism are otherwise sound, the cylinder can usually be replaced without changing the whole door.
Can you check why the lock keeps failing?
Yes. The team checks alignment, handles, gearboxes and keeps so the new barrel is not put under the same strain.
