How to Repair Central Locking

Model: (Various brands) Various
Part: Key

The video shows the diagnosis and repair of a fault in the central locking system, using both a homemade tester and a professional tester. The one indicated by the YouTuber is no longer available, but we can suggest its direct descendant, which you can purchase on AliExpress with the code 1005006381290085 for £26.49 with free delivery. Very often, the problem is simply a blown fuse. Use the tester to check that the fuse is intact; if it is, then that is not the issue. Using the tester, which helps trace the wire paths, you discover where the wire from the fuse goes. Eventually, you find a point where the wire is wrapped in insulating tape, and you expect to find a control unit or box; however, on this vehicle, the central locking is controlled directly by the alarm system. Check the alarm fuses: the first one is fine, but the second is blown; after replacing it, the locking system starts working again. The practical advice is to check the fuses before starting to dismantle anything. If you do not find a dedicated control unit, it is wise to check if the locking is managed directly by the alarm, as in this case.
