Disassembly - MobileKey Locking cylinder (Z4)

If you need to disassemble the half cylinder, please proceed as follows:

  1. Using a tool such as a screwdriver, grip into the two slots in the plastic disc between the thumb-turn and the profile cylinder housing and turn the tool while applying a little pressure. This breaks the disc.
  2. Remove the remains of the plastic disc.
  3. Engage the half cylinder using an authorised ID medium.
  4. While the thumb-turn is engaged, turn it anti-clockwise until it will turn no more (e.g. towards the lock when installed or holding the cam with your hand when not installed; see Step A in the diagram).
  5. Press thumb-turn towards profile cylinder housing until it stops (you will hear it click. If necessary, move thumb-turn backwards and forwards several times until you hear a click; see Step B and D in the diagram).
  6. If needed, engage the half cylinder once more using an authorised ID medium.
  7. While the thumb-turn is engaged, turn it anti-clockwise and apply pressure against the stop position (see Step B and D in the diagram).
  8. While applying pressure, pull the thumb-turn (including inside tube) from the profile cylinder (see Step D in the diagram).

NOTE

notice

You must not strike the thumb-turn during installation. Do not allow the cylinder to come into contact with oil, paint or acids.
