That seems annoying. Fortunately, replacing the battery in a key fob for a BMW 328i is not too difficult. Here’s how to go about it:
- Start by pressing and holding the little button at the key fob’s base. You can do this to take the metal key off of your key fob.
- Find a small hole by feeling around the key fob’s edge. Use your metal key or a small flathead screwdriver to remove the key fob’s back plate off.
- Remove the old battery with care. You must orient your new battery in the same direction as your old one, so be sure to take note of where the negative and positive terminals are located.
- Put the key fob’s fresh battery in there. As you do this, try to avoid touching the terminals because doing so could shorten the key’s battery life.
- Replace the back panel last. The two parts should click together when they are joined properly. After that, you may test out your new key fob batteries by inserting the metal key.

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.

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).
