AMG GT Keyless Entry Problem

I'm experiencing an issue with my 2021 Mercedes AMG GT hybrid with 213029 km. The keyless access has stopped working. A diagnostic shows an error related to the door handle electronics. I suspect a defective cable or plug connection in the door actuator or door switch system. Has anyone else seen something similar with their car door and locking system? I'm trying to figure out how deeply I need to investigate before disassembling the car door. It seems to affect all doors. Any thoughts?

Door handle issues, eh? Sounds familiar. I had a similar problem with my AMG GT... keyless entry failed. The door handle felt dead. Did you check the door switch? Could be a simple fix. Was it the same for all doors or only one?

When you say 'simple fix,' are we talking about replacing the whole door actuator, or was it something more straightforward, like just cleaning a connection or replacing the door switch? Was it accessible without removing the whole car door panel?

Nah, nothing major like replacing the entire door actuator. A visit to the workshop, and they found a loose connection in the door handle wiring. They fixed it quickly. It's worth having it checked out.

Okay, I appreciate the input. A mechanic took a look, and you were spot on. It was indeed a faulty plug connection related to the door handle. The whole thing cost me 95€ including diagnostics. Thanks for the heads-up!
