Before replacing the battery, try reprogramming the key. Hold the key next to the ignition slot without inserting it. Press and hold the top unlock button, the button nearest the key flat. Continue holding it, and press the center unlock button three times. If you key reprograms, you'll know it immediately.

Yes! Excellent advice. Then, if that doesn’t work maybe that battery is dead. Good luck everyone!!

@@robdude1969 Right! Trying reprogramming first will identify a dead battery, or other problem. I could not have been more surprised when my 20 year old spare key came back to life after being inoperative for so long. The battery had retained a partial charge even though the key had been nowhere near its charger (the key slot) in years.

Awesome, Thanks Rob. New battery ordered, fitted and it didn't work. Then I thought... maybe the key needs to be reprogrammed. This is the difference, your video helped. Next problem: The key unlocks the trunk / boot, it unlocks the doors, but wont lock the doors. Thanks again.

@@robdude1969 Thanks Rob... you get me then. :-) No it's not the lock... one key works perfectly. I think it is the little button under the BMW logo. I'll see if this has a dry joint on the PCB in the transponder / remote. I also did something else that could be on interest to your subscribers... I found a BMW at a wrecking year... it was relatively new when it was wrecked. The key was in the ignition. I asked the guy if i could by the key. He said "It's of no use to anyone, you can have it". the keys looks brand new right... so I removed the top layer and the PCB with the battery onto my metal key shaft.... Programmed the ley like you said to do....wulha.... looks brand new... :-)

What if the e46 had an aftermarket key fob installed would this still work if i bought a new factory key ?

Can I get your help. My key was being temperamental with locking and unlocking the car. I assumed it was a battery problem so replaced it. Now reprogramming won't work? Is there any other issues that could cause this

Hi Robdude. Thanks for this video. The battery removal and the programming or my 2 keys did go perfectly well. Just to share an idea, in order to seal the 2 key plastic parts together, I use the Tamiya extra thin cement (for plastic models). Just sand the parts that will receive the glue, apply the glue and put the parts together. 2 jours later, i applied the same glue à long the sealing line. It allows a waterproof sealing, and will offer an easier access to the battery if the battery needs to be reopened at a later stage.
