id091400805000

  Caution

  • Do not perform key registration or start the engine under the following conditions. Doing so could result in a key registration error or the engine not starting even with a correctly registered key.

  - If a large, metal object is close to a valid key
  - If an electrical device is close to a valid key
  - If two or more valid keys are on the same key ring

  Note

  • When an error occurs during the reprogram procedures, except when the PCM is replaced, repeat the procedure from Step 1. If you still cannot reprogram, confirm how many keys can start the engine. Then, perform the key replacement or additional key reprogramming procedure according to the valid key number.
  • To make a copy of the key or replace the immobilizer system component parts (the key (s) or PCM or both), the customer should bring all keys to the dealer. This is because the previously programmed key IDs are erased when reprogramming the key IDs into the PCM.
  • The immobilizer system cannot be deactivated.
  • Confirm that all registered keys can start the engine after the reprogram procedure. When confirming, wait for more than 5 s before inserting the next key.
  • When the customer does not need to register more than two keys, the procedures below are unnecessary after registering two keys.
  • If the engine is started during the key registration procedure, the key registration mode will be erased. Therefore, do not start the engine until the key registration procedure for all the necessary keys is finished.
  • A maximum of 8 keys can be registered for one vehicle.
  • To start the engine, two or more keys need to be registered.
