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
