How do you change the battery in a key fob for a BMW X3?
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.

What does a 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).

It appears that the left side of your glove compartment in your automobile will reveal a box that is the side of your key fob if you open the glove compartment and look there. This is what? It might be covered by a silicone mat, but it appears that you can start your car by simply inserting your key fob there (and also charge your key fob)
What happens if the battery in your BMW key dies?
You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.
Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.
Once you’re inside, put your remote key fob in the ignition slot or, if your car doesn’t have one, press it up against the steering column’s key markings. If your key fob dies, you will still be able to start your BMW using the start/stop button on the dashboard.
Can a BMW be used without a key?
Even if your E90 doesn’t have comfort access, there is a way to start the engine and start driving without a key. A BMW anti-hijack feature, that is. Simply put the key in the ignition and start the vehicle as usual. Once you’ve finished, turn off the engine and take the key out of the ignition. Pushing the start button now without a key will start the automobile in roughly 10 seconds, allowing you to take off. Although many of you may already be aware of this feature, I figured I should still share it with those who don’t realize that their BMW has it.
It’s more of a safety feature than anti-hijack. The automobile will still start if you have a key issue and stall out on the railroad lines, allowing you to get off the rails.
done this previously. After considering the potential consequences, I decided to stop using the “DIY comfort access” method. hehe. however, thank you for posting for others.
It works for both my 2007-1 series and 2008-3 series coupes, however if you open the driver-door or wait a little bit longer before restarting the engine, this option is disabled. I tested this about a month ago.
Since learning about it on this forum, I’ve been doing this for approximately a month. I haven’t had any problems with it, and yes, I also use it to warm up my car. No need to panic because the radio turns off after a few minutes, and in case you’re wondering, the car will still be running even if the key fob is distant from the vehicle. I put this to the test the other day when I visited Walgreens.
I do this to get my car warmed up. not necessarily to warm the engine up, but more to warm my seat and the cabin. It’s excellent if my car is parked on the street or somewhere else where you can’t leave the doors open while it warms up. (Or use the laser key to unlock the door)
I regularly engage in this. You don’t even need to hold the brake pedal down; just reapply it, press the start button, lock your doors, and dash into the store or back into your house. However, I suppose you have leftover heat if you are entering the store.
Yes, I’d rather to take a chance than have my valve train begin to tick because they aren’t getting lubricated during short trips when the car isn’t warmed up. I appreciate the guidance nonetheless.
SURPRISINGLY, not every recommendation made by businesses is in your best interests. They’re a business, so if they can convince you to ignore your automobile and end up having to pay for more extensive repairs later on, they win.
Not to bring up an old topic, but wouldn’t starting the car twice be necessary for those who use this method to warm it up? Since the initial cold start is the toughest on the engine, I believe it is best to let the car warm up at that time rather than turning it off and putting it through a second cold start. Any thoughts?
