Key Matching

Prerequisites:

• Battery voltage at least 12.0 V. We strongly recommend the use of a battery charger.
• You can match up to 8 keys.
• All keys are either new or were adapted to this car (IMMO-ID) before.
• While adapting each key, make sure to place the other keys away from the ignition lock (reader coil). The passenger seat is an adequate place.
• If all Keys are new OR the first inserted Key is new, the Ignition will NOT switch ON with this key.
  • Put the first Key into the ignition Lock, but do NOT switch ON the ignition.
