Jumpy electric keyless access failure

Sounds like a pain! I bet it's something with the door handle electronics. Have you checked the cable or plug connection of the component?

Could you provide more specific guidance on how to check the cable or plug connection you mentioned?

Honestly, fiddling with electrics can be risky. If you're not super confident, it's probably best to take it to a workshop. Could save you a bigger headache and expense down the line.

I took it to a workshop, and you were right – it was a defective connection in the door handle. The repair cost was 95€. Much appreciated!
