The other day, as I was leaving for work, my BMW key fob refused to unlock the doors. Fortunately, I have a spare and didn’t need to fiddle with the key kept in the fob, but the battery still needs to be changed. How do you unlock the battery cover on a BMW automobile key?
In less than two minutes, find out if your auto insurance is being overcharged.
I’m glad to hear you have a backup key fob because it can be frustrating to have a dead one.
You must first make sure you can unlock your key fob before attempting to open the battery cover on your BMW. Most BMW key fobs have a battery cover that can be opened, however if your key fob has a side notch, it is rechargeable. You all need to drive about for roughly two hours to recharge the battery.
Alternatively, if the side of your key fob is flat, you can use the following procedures to open the battery cover:
- Take the manual key out of the key fob.
- Find the opening’s tiny groove where the manual key is kept. On some key fob versions, the groove is not where the keys are stored; instead, it is near the bottom of the fob.
- You can pry off the key battery cover by inserting the key or a flat screwdriver into the groove.
- Replace the old battery by removing it.
- Reposition the battery cover by pushing it. After changing the battery, make careful to test the fob to make sure you won’t get locked out again.
In the unfortunate case that changing the battery doesn’t work, you’ll probably need to buy a replacement fob; you should budget between $400 and $650 for one. Use the Jerry app to save money on your auto insurance if you want to make the cost a little more bearable.
In just a few seconds, the Jerry app compiles quotes from more than 50 of the best insurance providers, including Travelers and Progressive!
