Navara Central Locking Failure

I also drive a Navara and faced a similar issue not too long ago. Has the security system been recently activated or deactivated? It might be a simple reset. Have you checked the fuses related to the door locks and locking mechanism?

I'll check the fuses. I've tried everything I can think of to reset the security system, but no luck. What specifically did you do when you had that problem? Did you find a permanent fix?

In my case, the problem was more complex than a simple reset. I investigated the symptoms and the error memory and I am afraid to say that it might be a defective component. My advice is to take it to a workshop to fix it.

Took it to the shop, and you were spot on! Turns out it was a defective cable connection, exactly as the error code suggested. They charged me 95€ to fix it, but at least it's working again. Thanks for the heads-up!
