XC90 Central Locking Failure

I've got an XC90 and had something similar. It started intermittent then died. Did you check the key fob batteries? It's a long shot, but easy to rule out.

I replaced the batteries in both key fobs, but that didn't fix it. The problem may be in the vehicle itself. Did you have to address the locking mechanism after checking the key fob?

Yeah, tried the fob thing too. Sadly, it ended up needing a look at the workshop, they traced it to a defective cable/plug connection. Definitely sounds like your issue. Might be worth a visit.

Appreciate the insight. I'll schedule a workshop visit to inspect the cable and plug connections. The estimated repair cost is 95€.
