Ignition switch and lock cylinder

The switch the key or the start button operates, and the lock barrel it turns in.

How you know it is this

  • A key that will not turn, or turns without anything happening
  • Electrics that come on and then drop out
  • A key that will not come out
  • The car not recognising the key at all

Worth knowing before you buy

  • On many Mercedes this involves the electronic steering lock, which is a coded module — not a mechanical barrel. That changes the job entirely.
  • Anything with the immobiliser in it has to be coded to the car, and key programming may be needed.
  • A worn barrel and a worn key wear together. A new barrel with an old key often does not solve it.

What we need to quote it. The chassis number, and whether the car has a key or a start button. The chassis number settles the generation, the body and usually the engine in seventeen characters — it is on your mulkiya. A photograph of the old part helps where there is more than one version.

Starting and charging — schematic, to show where the part sits. Arrangement is right; it is a diagram and not a fitment reference.
