Adding a remote door lock/unlock function to your BMW key
Follow the steps below to enable or disable the remote function of a replacement BMW key:
- Close and lock all of the doors while using every remote in the vehicle.
- Using the new master key, turn the ignition to the “run” position.
- without opening any doors, remove the key
- On the new master key, hold down the UNLOCK button (the arrow button).
- Press the key LOCK button (the BMW logo) three times quickly while maintaining pressure on the unlock button. Press the buttons swiftly but slowly, pausing for only one second in between each BMW logo press.
- On the final button press, simultaneously release both buttons.
- To verify the initialization of the remote feature, doors will lock and unlock. To enable all keys on the remote door lock system, use the same button press programming method for each key within 30 seconds (up to 4 remote keys).
Follow the steps above with all of your keys except the one you want to remove if you have lost a key or would otherwise like to disable the remote function of one of your keys. This procedure will remove the outdated or lost door remote from the list of door remotes that are currently in use, rendering the lost key useless for remote vehicle unlocking.
Any remote key that isn’t programmed in the same session won’t be able to lock, unlock, or disarm (FZV & DWA) the car, but it will still work to start it (EWS).
A dead key fob will a BMW start?
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.

My key stopped working, so I naturally looked for guidance on E-46. The discussion suggested unlocking the key and changing the battery rather than purchasing the $240 new key from BMW. (For the record, I used a battery from CVS, a screwdriver, and DIY from the owner’s manual to complete this on my wife’s Mazda.)
1) Turn the ignition to position II and quickly—about five seconds—remove the key.
2) Press the lock button three times in quick succession while maintaining pressure on the unlock button on the key.
3) To complete the operation, the doors are then locked and unlocked.
In conclusion, re-syncing the key is much simpler even though DIY battery repair is fantastic if the battery is truly dead. Try it out first.
For the record, I attempted it again after the initial attempt had failed and was successful. Thanks for the tip on a simple solution.

What does the 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).

The cost of a BMW key fob
The price of a 2020 Toyota Sienna fob was comparable. Dealers, however, gave prices as low as $150 to replace a key fob for a 2017 Honda Accord.

A BMW key fob can be programmed by a locksmith.
Dealerships charge hundreds of dollars to complete the replacement of a BMW key due to the complexity of the operation. The costs of employing a dealership start to really build up in the following ways:
- Your automobile won’t start without a key. Your automobile will need to be towed by the dealership into the service area before any repairs can be made.
- Key fobs are not stocked in excess or as new ones at BMW shops. It will take about 10 days to receive your customized key once you place a custom purchase. Your automobile is unable to be driven at this time.
- Your new key needs to be programmed to the vehicle when it arrives, and the immobilizer system as a whole needs to be reprogrammed to recognize the new key fob. Dealerships bill for their time at a premium hourly rate, just like any of their other services.
This process not only takes a lot longer, but it also costs at least twice as much. You’ll wind up paying the dealership at least $500 to replace your BMW key when everything is said and done. There must be a better approach!
There is, in fact, a much better way! You can save yourself hundreds of dollars and a lot of hassle by working with a reputable locksmith like Cheap Lock & Key! You can have an immediate replacement performed at your location for roughly $250 to $350, which includes a new key fob and the reprogramming of your immobilizer system. The keys that locksmiths use and stock up on are identical to those from the dealership.
After the locksmith has finished replacing the key, make sure to test locking, unlocking, and starting the car completely. Therefore, the next time you need a new BMW auto key, make sure to check with your local locksmiths first before going to the shop!
