How can I open a BMW key fob?

I accidentally dropped my BMW key fob in a massive puddle and it’s no longer working. I want to try putting the fob in rice to dry it out, but I need to remove the battery first. How do you open a BMW key fob?

key fob. I hope the rice trick works!
The process to open a BMW key fob is simple but if your key fob has an indent on the side, don’t open it because the battery is rechargeable, not replaceable. If you have one of these keys, you can recharge it by driving around for two hours.
If your key fob does not have the indent, you should:
  1. Remove the mechanical key from the fob.
  2. Locate the small groove in the opening where the mechanical key is stored. On some key fob models, the groove is towards the bottom of the fob, not in the manual key storage compartment.
  3. Insert the mechanical key or a flat screwdriver into the groove and pop off the key battery cover.
  4. Remove the battery.
If putting the key fob in rice and replacing the battery doesn’t work, you should expect to pay $400 to $650 for a replacement fob with some higher-end models requiring keys that cost close to $1,000.
