Identifying Your Door Lock Gearbox
We can help you easily identify the gearbox you need. All we need is a photo of your current gearbox which you can email to us. It is also useful if you can provide any brand names or codes which may be present on the gearbox or door lock rail.
Installing Your Door Lock Gearbox
Installing your new gearbox is quite simple and for the most part just requires you to remove a few screws. Some types of replacement gearboxes can be a little more difficult. If you're finding it difficult or would like some installation advice before purchasing, just reach out to our team and we can provide you with full details and instructions.
