Mercedes GLS keyless entry problem

My 2016 Mercedes GLS with a gasoline engine is throwing me for a loop. The keyless entry is completely dead. I scanned it and there's an error stored pointing to the door electronics. Mileage is at 143508 km. I am thinking it’s probably a wiring fault or a loose plug in the car door somewhere. Anyone else seen anything similar?

I had a similar sensor issue with my GLS. Have you checked the door actuator? It's often the culprit when the keyless go stops working. Could be a wiring fault as you suspect, but sometimes it's just the actuator itself freaking out.

Good call! Where exactly is that door actuator located? Is it a pain to get to? I'm hoping it's not buried deep inside the door. I'm decent with tools but I'm no pro.

It’s inside the door, you'll have to remove the door panel. If you aren't comfortable doing that, you might consider a workshop. My local shop charged about 95€ to diagnose and repair the wiring fault.

Thanks! I took it to the shop. Turns out it was a corroded connector on the door electronics, just like you said! They cleaned it up, and everything is working again. Appreciate the help!
