The BMW keyless entry remote replacement battery
CR2032 can be purchased
on Amazon or at any auto parts store or convenient store for less that $5 for a pair.
After you have inserted the new battery in the key fob with the positive side up you can push the plastic battery cover back into place and test your remote to make sure it is working.
Troubleshooting: If the key fob is not working after the battery has been replaced try inserting it into the ignition for 20 seconds,
this may synch the key fob to the BMW again. You may also need to have your spare working key fob in the vehicle at the same time in order for it to synch. (Please do not quote me on this
synching method as I read it somewhere else and it would only work with a key fob that is matched to your VIN number already) If the key fob is still not working make sure you do not need to
replace or fix a
blown fuse or relay somewhere or that you did not put the battery in upside down.
