Insignia Central Locking Failure

Hi, I'm having a weird issue with my 2010 Vauxhall Insignia diesel. The central locking has completely stopped working. The doors won't lock or unlock, neither with the remote nor the button inside. I scanned it and there's an error stored, but nothing specific. I'm thinking it might be a defective cable or plug connection somewhere. Has anyone else run into this?

The central locking system of a 2010 Vauxhall Insignia stopped working entirely, affecting all doors and showing a generic error code. The issue was suspected to be a defective cable or plug connection. Suggestions included checking the fuses and inspecting the wiring loom in the door, as these can be common failure points. Ultimately, a workshop diagnosed and resolved the problem, confirming it was due to a defective cable in the driver's side door.

Did this summary help you solve your problem?

I had something similar happen in my Insignia. Start by checking the fuses. A blown fuse can knock out the whole central locking system. Also, have you checked the wiring loom that goes into the door? They can get damaged over time, especially where they flex every time you open and close the door. Any signs of wear and tear there?

Thanks, will check the fuses first thing. And the wiring loom... good shout. When you had the similar issue, were all doors affected at once, or just one? And did it throw any specific error codes, or just a generic 'something's wrong' message?

Yep, all doors went at the same time. Pretty sure mine chucked up a generic code too, nothing that pointed directly to a fault location. Given everything's dead and you've checked the basics, it might be worth getting a workshop to take a look. They have diagnostic tools that can pinpoint the exact break in the circuit.

Cheers, I appreciate the pointer about the workshop. Got it looked at, you were spot on re: the wiring loom on the driver's side door. It was indeed a defective cable / plug. They sorted it for 95€ Thanks again!
