Deleting BMW E46 key.

[clanser]

Hi Chaps'
I recently bought an E46 with only one key.
To be sure the previous owner cant drive off with my car late at night if he has the second key,is there a way to delete all keys and reprogram the one I have ?
Also code a second key I will get from the stealer'
Cheers for any help.

hi

yes it is possible with gt1 via service function ... enable/disable key.
the new key must only sync with the central locking... for this step u need both keys.

1.close the car mecanicly from drivers door
2.open the car mecanicly from drivers door
3.get into the car and close the door(driver side)
4.with one of the key, turn to the 1st position briefly just so you see the mileage until service light come up,then turn off and remove key.
5.Press and hold the door unlock button and whilst doing that press the door lock button 3 times then release the unlock button, as soon as you release that unlock button the door pins will shoot down and back up again ... it's just a sign to tell you that the sync was successful.
If you have a second key then ...don't repeat step 4 ...just pick up the other key as soon as those door pins have shot up and down and do the same as you did with the first key.
Hold the door unlock button and press the lock button 3 times then let go of the door unlock button and the door pins will shoot up and down again.


have fun!

Cheers for that info mate,
Just to clarify,so any key not initialised that way,at the same time, will not start the car,right ?

hi

your key has two separete functions:

1. immo...only for engine start
2. remote... open/close the car


1. can be activate/deactivate from gt1-but u canot use a key from another car.

2. u must follow the procedure above.


have fun!
