In fact, it’s possible that you won’t be able to change the batteries in your BMW X3 key fob. Because some BMW fob batteries are rechargeable, they cannot be replaced. You just need to drive your car for at least 30 minutes with the key in the ignition to charge a key fob of this style.
However, if your key fob does really feature a replacement battery, you can do so by performing the following actions:
- By pressing down on the metal tab at the bottom of your key fob and sliding the metal key out of the way, you must first remove the metal key.
- Next, use a flathead screwdriver to pry the two parts of the key fob apart by inserting it into the little hole that was left behind.
- After making a note of the locations of the battery’s negative and positive ends, gently remove the old battery from your key fob.
- Make sure the positive and negative ends of your new battery are positioned correctly before inserting it.
- Reinsert your metal key after reassembling the key’s two parts until you hear a click.
- Check the battery in your key fob to make sure it is functioning properly.

- The battery will eventually run out if the FZV keys are not utilized (i.e., kept in a drawer) after about 1.5 years.

What does my BMW key’s diamond button do?
Does anyone have any knowledge of what the key fob’s diamond button is meant to do?
The included manual is incredibly succinct. It refers to a “Headlight courtesy delay feature,” although it’s not entirely clear what this feature performs. “If the standby state is switched on and the high-beam headlights are enabled, the low-beam headlights remain on for an of time,” the text states. Even if “… for a period of time” is meant to be “… for a length of time,” that still doesn’t adequately describe what this feature is.
According to the description, it can only be used when the automobile has just been turned off and the high beams are on. However, when the car is locked, the button appears to have some effect. The inside lights occasionally come on. The headlights occasionally come on. It is quite unpredictable and challenging to duplicate.
What experiences do others have? Has anyone figured out what this button’s actual purpose is?
It is unfortunate that it cannot be set to perform things like open the windows or sunroof, switch on the heating, or other things!
Mine has two options (330e in Belgium): turn on the lights in the house or turn on the air conditioning. In the options for the car, I can select the default function.
It briefly illuminates the headlights in my automobile. Excellent for illuminating the path to your front entrance or finding your car at night in a big parking lot.
Check the “Home lights” setting under “Exterior Light Settings” on your iDrive to make sure it is not set to 0 seconds.
My headlights now turn on for 10 seconds when I hold the diamond button on the key because I set mine to that duration (G20 330i).
Should I reprogramme my car after changing the battery?
Yes. Your settings will need to be reset. The dealer will typically do it for free, but no guarantees can be made.
