How much does it cost to repair the central locking on an S reg Ka3 ? The drivers lock doesn't appear to be connected. The two door locks work with the key individually but only the passenger side makes the noise associated with central locking.
A new latch assembly will be £80+ plus labour charges you might be able to get the latch cheaper from a scrapyard, but the fault might not be the latch, it could be a broken wire in the flexy tube between the door and the car's body
