When the handle feels loose, the lock won't engage, or you can hear a 'spinning' sound when you lift the handle — it's the gearbox, not the whole strip. Replacing just the gearbox is a fraction of the cost of a full strip replacement.\u003c\/p\u003e\u003ch3\u003eWhat's included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIdentification of your gearbox by brand and lever spacing\u003c\/li\u003e\n\u003cli\u003eSupply of matched or universal replacement gearbox\u003c\/li\u003e\n\u003cli\u003eRemoval of door slab from frame if required for access\u003c\/li\u003e\n\u003cli\u003eInstallation, alignment and lubrication\u003c\/li\u003e\n\u003cli\u003eFunction test of all locking points\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePricing\u003c\/h3\u003e\u003cp\u003eStandard gearboxes from \u003cstrong\u003e£110\u003c\/strong\u003e.

If the hooks don't move at all even with a working handle, it could be either.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan you replace a gearbox without removing the door?\u003c\/strong\u003e\u003cbr\u003eYes in most cases — we can usually access it through the door edge with the door in situ.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long does a gearbox last?\u003c\/strong\u003e\u003cbr\u003eTypically 8–15 years depending on use. Slamming doors and lifting the handle to lock without first turning the key shortens life significantly.\u003c\/p\u003e\u003ch3\u003eService area \u0026amp; guarantee\u003c\/h3\u003e\u003cp\u003eWe serve \u003cstrong\u003ePreston, Lancashire\u003c\/strong\u003e and the surrounding PR postcode area.
