Ignition lock cylinder failed. Remove it and take it to a locksmith to have it repaired or go buy a new lock cylinder from BMW. $$$

This a safety feature in the BMW if the ignition is forced it breaks
need to replace the ignition cylinder

Removing and installing/replacing lock cylinder for steering wheel lock

Car with ring antenna:
Remove lower section of steering column trim.
Using special tool 61 3 300, press ring antenna off locking cylinder.



With ignition key, use workshop key for better accessibility, turn lock cylinder to "R" position = radio, windscreen wiper, fan.

Caution: On vehicles with freewheel lock cylinder up to 10/95: twist lock cylinder back through 12°.



Push special tool 32 3 110 into hole of lock cylinder an swivel handle forward by approx. 90°. Remove lock cylinder.



You can substitue a pick for the tool

the thing is that you can replace it, but the still will not run, the transponder and key have to be reprogrammed at the dealer only

Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Some models: Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously

To change batteries remove panel back of key then screws on plastic bar
Batteries are available from your local motor factor shop
You might not need new batteries try re programing as described above

either the lock cylinder came apart in the housing,which if it did you will need a new cylinder/key/housing and program the housing and build the lock cylinder(take to deal)or the ignition switch went bad (electrical part on end of lock cylinder) bith are common ion issue. i would take to the shop,they should have all those parts in stock
