Can you tell me here this plastic trim is on the hatch?

My new OE key I got from BMW just stopped working one day last year. It worked for about 18 months. The central locking button inside works as expected, as does the door lock.

Here you got the exact location.

Might be also the battery in your case.


Also figured out something, i don't think it created the issue but definitely something to consider for whom want to replace their batteries.

So since i started searching about replacing the batteries of the remote key after buying the car, i found out that the replacement batteries are LIR2025 3.6v.

Except it's not...

Apparently the closest to OEM fit are VL2020 3v.

Should have went further than trusting ebay on search results for "E53 key battery"...

Ordered a couple of those, will keep updated when received and replaced.

Yes, I think that's all posted here somewhere, I think it was the VL2020 that I used years ago and has been good, but I think I remember finding the OE Sanyo purple battery available somewhere afterwards.

Could be, but the fob was new from BMW only about a year before. Tried charging it with a Philips toothbrush charger in case the in-car one wasn't working, but that didn't do anything.

Thanks for the pic. I'll have a look. Maybe a hard slam knocked a wire loose...

Also saw a topic where the power wire was damaged in the rubber boot that's between the hatch and the car
