The rechargeable battery in one of the key fobs for 2019 Z4 (with out comfort access) is on its last legs and only works within when a few inches from the car. I've watched the YouTube video on how to replace the battery, and am confident I can complete the task. My problem is, all the sources for a replacement battery list every model of BMW imaginable from that same time, except the e89. Is it the same rechargeable battery that works in the other BMWs?
