My key unlocking range is pathetic but at least once I replaced my amplifier it resolved my Comfort Access issues. I may try a loop of wire like you used. How is your FM radio reception?

FM and AM radio work just fine, even before I switched the diversity amplifier.
The rib cable was broken right up to the glass, so repair is impossible I think.
Works well enough with the "antenna loop" trick

My Ride: Bmw e61 525d 2005.
It turns out that contact no. 1 that goes to the rear window is the antenna for the car keys.
Contact no. 2 goes to the AM antenna which is glued to the spoiler.
There is a break in the cable to the rear window, so I have little range on the signal from the keys.
I glued a cable in a loop inside the spoiler and plugged it into the antenna amplifier, and it gave a better signal.
I will probably have to change the rear window for it to be as good as before

Did you manage to sort this out? I have the same issue, wiring has been replaced through the tail hinge and still not working to unlock with the remote. Thank you in advance

Have you replaced the antenna amplifier? That appears to be the most-common problem when these remote issues start. I know it was my problem.

Something like this: https://www.ebay.ca/itm/284876303573...3ABFBM9Jqes-Zh is what I bought.
On the E61 it is mounted under the rear spoiler at the top of the rear hatch glass. All radio signals (including the key remotes) go through the antenna amplifier (sometimes called diversity antenna).
