    If you have the diamond shaped key and it’s not unlocking or locking the car you may need to replace the internal battery. It normally charges as you drive the car but if the battery is worn out it won’t hold the charge as well. Here is a video showing you how to complete.

    My car prompted me to replace the battery in my key fob. I'm complied with the order. I'm confident that the battery is installed correctly. The battery is new from Lowes. Nonetheless, I'm still getting the error message. So I tried using my husband's key fob. I get the same message. This is...

    re: key issue So, my wife left my BMW key on top of her car when she drove off in the other car to work. The keys fell off the top of the car and were run over by another vehicle, or maybe even multiple vehicles. The key stopped working about a month later and is no longer charging up. Could...

    I bought a used e46 323i and the remote locks didn't work. I followed this guide http://forum.e46fanatics.com/showthread.php?t=451510&highlight=key+battery with success. My soldering skills are fairly good so I'm confident that the connections were made properly, but the key will not program...
