As of yesterday, driver’s door on my Kodiak no longer locking using the remote or when pressing the back of the door handle. All other doors will lock. If I take the fob out of range, I can still open the door (just that one, all of the rest are still locked). Alarm sounds when I open the door.
I can lock the door using the thin key only. Car drives fine, and tried both fobs, which both have new batteries fairly recently installed.
So it’s not a synchronisation issue with the fobs, as far as I can tell. I have tried wd40 in the lock and down the door from the top. Given that I can lock via the thin key, it must be software, not mechanical though.
Car booked in late next week (earliest the dealer could do) and as out of warranty I have to pay a diagnostic fee.
Any suggestions gratefully received. Thanks.
