Common signs of a mechanism problem
The handle may become difficult to lift, the key may only turn with pressure or the locking points may stop engaging. Continuing to force the door can place more strain on the gearbox and turn a developing fault into a complete failure.
Finding the cause before replacing parts
A similar symptom can be caused by the cylinder, handles, multipoint mechanism or door alignment. SecuriKey checks how the door operates and identifies the failed component before discussing the appropriate repair.
Repair, replacement and adjustment
Depending on the fault, the solution may involve adjustment, a replacement cylinder, new handles or a compatible mechanism. The available options are explained so you understand what is required and why.
