Hello Eamon. Nice to hear from you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Is this locking issue occurring only when using the key fob or does it also occur when using the interior lock and unlock buttons?

Without knowing all of the information like the vehicle history, the components that have been tested or replaced, and the results of any tests that need to be run, I can only give you a general answer to your question. I recommend checking all fuses in all fuse panels to see if any of the fuses are found to be blown in any way needing to be replaced. If all of the fuses are found to be o.k. and if all of the central locking stopped working at the same time, this can indicate a fault with the body computer/ECU internally to where it has failed electronically and has to be replaced. I recommend having the body computer tested and checked using a fully compatible scan tool plugged into your vehicle's data port that is able to read all of the computers in your vehicle to see if any codes come up. If any codes come up they will need to be diagnosed to pinpoint and repair this issue. Electrical testing will need to be performed as well to verify that the body computer is in fact at fault needing to be replaced. This type of testing can cost around $100. The cost to replace the faulty body computer can cost around $500 in some cases and has to be set up and programmed by a dealer when it is installed.

Glad I could be of some help! I hope everything works out well for you! If there are any additional questions on this issue that should arise, please feel free to reply and ask! Thank you for choosing Just Answer for your questions. Have a great day!
