Here is a little demonstration video on how to replace the battery in your 7 Series key fob without comfort access. This process is different if the fob does have comfort access. If your fob is a comfort access fob, click this link to see the process -
This process is fairly involved since the battery isn't easily removeable. Here are the steps:
1) Use a knife or thin screwdriver and split the cases in halve. Score the sides with a knife and then use a screwdriver to dry the two sides apart.
2) Apply a little flux to the two solder points that currently connect the old battery.
3) Use a solder wand / iron to release the old VL2020 battery.
4) Line up the new VL2020 / ML2020 into the two 90 degree slots that the old battery just came out of.
5) Solder in the new battery. Clean up the old flux if you desire.
6) Use superglue or replacement case to put the fob back together. I recommend using a replacement case instead of superglue. You can find yours here - amzn.to/3D0NJlm

Bro you made it seem more hard than it was

[@royalhines5225]

I tried this with my 2004 BMW 745Li for the non-comfort access key fob. At first it beeped once and then nothing thereafter. Now my key fob will not even stay in the ignition it slides in but then slowly pushes out. I even brought a replacement key fob case thinking I messed my up but still will not stay in ignition so now I can't start the car with this key fob that was working prior to the battery replacement. Do you have any clue why it won't stay in ignition any more? Thx.

Can you send me the link to replace the battery into a 2008 BMW 750 LI V8 4.8 L I also think that in that process they killed the alternator because all the lights are on in the car and I couldn’t get it out of gear, the gear, the only lights that wouldn’t turn on are the gear lights And I have pictures to send you
