If learning key is to be replaced, master key, learning key, immobilizer control unit and Honda PGM Tester are required.

If immobilizer receiver does not operate, an immobilizer receiver is required. If immobilizer control unit does not operate, master key, learning key, immobilizer control unit and Honda PGM Tester are required. If PCM is to be replaced, Honda PGM Tester is required.

If ignition switch is to be replaced, an ignition switch (with immobilizer receiver), immobilizer control unit, master key, learning key and Honda PGM Tester are required.
