Hi, i checked the fuses before (all in related to the central locking system, marked with red arrow in attached photo). I'm wondering if these are the correct fuses to check?

Also, I just picked up a 2010 BMW X5 35D with working key fobs, so I will most likely swap the transmitters over this weekend to check if it is in fact the issue and report back (both are same frequency).

Let me know if the fuses are the correct ones that I've been checking. Thanks!

Yep. They’re the ones.

You may see a thread I started because I couldn’t lock my car with the remote. Had to use the little metal key.

It was a fuse. Unfortunately I did not note which one. But a burnt fuse is obvious.

Good luck.

Thanks, I checked all the fuses mentioned in the 'central locking system' again, this time using the multi-meter. (both in trunk and under glove box). All fuses are good, so my problem is either with the diversity antenna or something is going on with the key fob not syncing with the CAS. Will update the post over this weekend once I try to swap the diversity antenna from a working vehicle. Thanks for all the suggestions.
