Hi,

I got a problem with my Z4 key.

I can open the car with the key manually, and when i try to encode (following hold tree times the button method) nothing happens. But, with my other key this method works.

The motherboard of the key have changed the battery and revised with a electrician friend, and its says is ok. So... what's the problem?

Thanks
 
You probably already know, but just in case, you have to code both key within 30 seconds of each other, for them both to get the same codes.

If i understand correctly, you suggest to encode the key that works and 30 seconds later try to encode the key does not work? Thanks

If i try to encode this key, doesn't work the remote open, but the car starts with both keys. Its very strange...
 
Full Process follows:-

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. (Within less than 30 seconds)

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

Don't wait.
