Function and location
The complete steering lock casting combines a lock cylinder, locking pin and a round, 7-pin ignition starter switch with terminals 30, 15 and 50 as well as P30 for the parking light. When the key is removed, the locking pin extends and locks the steering column.
The lock is installed on the steering column tube under the steering column trim; it is fastened via the flange holes.
How can you tell if an ignition lock-steering lock is faulty?
- The key is hard to turn or won't turn at all
- The steering stays locked even after turning the key, because the locking pin doesn't retract
- The starter motor doesn't engage even though the key is in the start position (terminal 50)
- Ignition and connected loads (terminal 15) fail sporadically
- The parking light (terminal P30) can't be switched
Compatible vehicles
W123 model series – petrol (approx. 1976–1986):
- 200, 230, 230 E, 250, 280, 280 E
- also Coupé C123 and T-model S123
S-Class W126/C126 (up to approx. 09/1989):
- Sedan W126 (SE/SEL)
- Coupé C126 (SEC)
On W126 vehicles from approx. 10/1989, a modified lock cylinder was fitted – see "not to be confused with" below.
This steering lock can be identified by the housing stamping of the 0160 family, as fitted in the W123 and W126 model series. A different steering lock with the stamping 1900.01 was used for the later W201/W124 generation; that version does not fit this part.
⚠ Important: compare the part number before buying
Design and connector pattern are decisive for steering locks. This part belongs to the W123/W126 era (housing stamping 0160 family). Please compare the design, connector pattern and – if present on your old part – the part number 1:1 with the product photos. The lock also comes with its own keying and therefore does not match the rest of your vehicle's lock system (doors, trunk) unless the cylinder is re-keyed.
Does not fit:
- Diesel models (the version with two vacuum ports is required there)
- the newer design of the W201/W124 era (stamping 1900.01)
- W126 from approx. 10/1989 (modified lock cylinder)
- W113 Pagoda, early W108/W111, W110 (other lock families)
