The ignition switch can wear which can cause malfunction (e.g. no starter).

S1

The ignition switch used in the Elise S1 is like the rest of the steering column from GM/Vauxhall/Opel (e.g. Corsa B). The GM spare part number is 914852 or 90389377.

IMPORTANT!!! To remove/insert the ignition lock and/or switch ensure the key is inserted and is set to position I (key vertical and position where normally the radio is on but ignition is still off).

Ignition lock

Remove the ignition lock

Position of the key and unlatch the lock
  1. Remove the column shroud (7 screws and 1 nut for the trip switch)
  2. Insert key and set to position I (key must be vertical - see picture)
  3. At the front side (the side where the steering wheel is) of the outer barrel is a small hole. Press the short side of a small allen key into the hole (see picture). At the same time press the lock by the key towards the column and gently wiggle the lock until is comes loose. The lock is pressed out by spring tension.


Insert the ignition lock

Unlatch the steering wheel lock
  1. Before inserting the ignition lock make sure the steering wheel lock is disengaged. Use a small screwdriver to push the mechanism downwards until it locks into place (see picture)
  2. Ensure the key is inserted and is set to position I. Test if the locking notch on top of the ignition lock can be pressed in until it is level with the outer shape of the lock.
  3. Press the lock into the barrel until it locks into place
  4. Check function and reattach the shroud
