STEERING LOCK

Model:
318i (E3O)

To improve the theft protection afforded by the steering lock, a new design has been developed. The new steering lock still engages only when the ignition key is withdrawn, but unlike the previous design, will engage fully in almost any position of the steering wheel as soon as the key is pulled out. This makes it much easier to engage the steering lock properly when the car has been parked with the wheels turned. Previously, the steering wheel had to be forcibly turned until the lock engaged. The lock now engages after only a slight turn of the wheel with less effort needed to release it.





When the ignition key is removed from the ignition switch, the lower part (1) of the ignition lock jumps back and the spring loaded locking lever (2) is moved, so that the square section bar (3) engages in one of the 26 locating points. In this position, it is impossible to remove the steering wheel for service or repair.

To remove the steering wheel, the ignition key must always be inserted in the lock. The same applies to removal of the steering column trim (which is possible only after the steering wheel has been removed).

In addition, the new steering lock is stronger, offering additional protection against the locking pin shearing off when force is exerted on the locked steering wheel.

Protection against removal of the ignition lock barrel, which would enable the steering lock to be released, is obtained by the fact that the lock barrel can only be removed if the correct key has been inserted.

All joints and faces between the individual elements of the lock are reinforced or overlapped so that it is effectively impossible for unauthorized persons to break open the lock.
