Is your uPVC or composite door properly locked — or simply closed?
With most multipoint doors, pulling the door shut only engages the central latch. To activate the hooks, rollers and bolts, you normally need to lift the handle and then turn the key or thumbturn.
If the handle feels stiff, the key becomes difficult to turn or the door needs to be pushed or pulled into position, do not keep forcing it. Misalignment can place additional strain on the gearbox and eventually cause a complete lock failure.
Secure Smart Locks Ltd provides multipoint lock diagnostics, door alignment, gearbox repairs and cylinder upgrades across Lincoln and surrounding areas of Lincolnshire.
If your door is becoming difficult to lock, arrange an inspection before a minor problem becomes an emergency.
