Won’t let me program my fob key.

Fob battery needs to be charged before you start syncing, place it on a toothbrush charger overnight to charge it, on the car it would normally get charged when its in the ignition with the engine running. Then use the proceedures listed below to sync the fob, if you have more than one key they have to be synced immediately one after the other so they take the same sync info.
BMW Z4 - Key Remote Programming

Three methods to try:

Method 1:

1. Working from within the vehicle and with the doors shut

2. Turn ignition to position 1 and back to off within 5 seconds.

3. Remove the key from ignition and press and hold the unlock button for 15 seconds during this time press the key lock button 3 times within 5 seconds.

4. Release both buttons.

5. Doors will lock and unlock to show correct programming has occurred.



Method 2:

To do this procedure you need to have one working key and one key that needs to be programmed.

1) Get in and close all doors.

2) Turn on the ignition and turn off quickly. (No more than 5 seconds) to start the process. Next action must take place within 30 seconds.

3) Remove the 1st key.

4) Hold the key up near your left shoulder (this is so it is closer to the remote receiver antenna.

5) Hold down the unlock button and press the lock button 3 times. Release the unlock button and the doors lock which confirms the operation.

6) Quickly repeat steps 4 & 5 for key #2 etc.

If it does not work, try doing the keys in opposite order. Key 2 then key 1, vs 1 then 2.



Method 3:

Alternate if you do not have a working remote

1. Turn key to position 1 five times very quickly 2. Remove key 3. Hold unlock button then press lock button 3 times, release unlock button.

4. If you have another key do the same button pressing within 30 seconds 5. Turn on ignition to finalise.

PLEASE NOTE: This programming procedure programs the remote control part of the key. Any transponder chip for the immobiliser (starting of car) will not be programmed and must be done by a specialist.
 
If you're trying to program the key rather than sync it then you'll need a programmer such as the AK90+.
This should explain it (plus the guy doing the programming is your side of the pond):

Omg!!! Method 2 worked bro!!! Thank you so much!!!!
 
Love this forum. I’ve had my car two weeks now and I don’t think either key had been working for a few months. I’ve now got one key working through method 3. Great result.

It doesn’t drop the hood on a long press though which I think is an upgrade a previous owner did so I suspect that is long gone. But great to be able to use a remote again. I can only get one key going at a time though it seems which isn’t the end of the world at all.

If you only do one key at a time it will create a new code and the other one won't work.
You have to do them straight one after the other. So when you do the first one and release the buttons the locks should lock and unlock again. immediately pick up the second key and do the button pressing on that. Do not put it in the ignition, just the button presses. Hopefully that should work?

Thanks I’ll try that when I get home.

This worked on the first try for me! Thank you!

Originally, each time I would try to program a fob, the other wouldn't work once I programmed the new one, and vice versa.

This was on a 2003 Z4 E85 2.5i

This worked for me a while back.
I also fell foul to putting the 2nd key in the ignition and the process failing.
When doing just the button presses, it worked. :thumbsup:
