Lexus UX central locking failure

The symptoms point to a defect in the cable or plug connection of the central locking component itself. Have you checked the fuse box for any blown fuses related to the central locking system?

Thank you for the quick response. Could you please specify which fuse I should be looking for? I'm not very experienced with car electrics and want to make sure I'm checking the right one.

Unfortunately, without the specific wiring diagram for your UX, I cannot pinpoint the exact fuse location. Given the stored error, it is likely more than just a fuse. I would advise having a qualified technician diagnose the cable and plug connections.

Understood. I appreciate the advice. I took it to a workshop. As you suspected, a defective plug connection was the issue. Repair cost was 95€. Thank you!
