Other fobs interfering with key

[Bking]

I don't know if others have experienced this but it seems like my apartment garage fob is interfering with my Z key fob. My car will not sense the Z key within proximity, i.e. can't unlock/lock doors/hatch, display shows "No Key" sign.

I either have to separate the fobs or wave the Z key around inside the cabin to start my car, but only after a few tries. Is there any way to fix this? I know carrying the keys separately should fix the problem but I really prefer to have all my keys together on one key chain.
