Remote Control Is UNLOCKED / Key Is UNLOCKED During The Alarm

If a remote UNLOCK occurs during an alarm sequence, UNLOCK will activate, the hazard lamp will blink 2 times, and then Anti-Theft system will DISARM.
The horn, hazard lamp, and start inhibitor will be off.
If a key UNLOCK occurs during an alarm sequence, the Anti-Theft system will DISARM. The horn, hazard lamp, and start inhibitor will be off.
When trunk key UNLOCK occurs, the horn, hazard lamp and start inhibitor will be off, however alarm on hold mode is on and the ARM state for other entry ports remains activated. (If the trunk is closed and remains closed for more than 2 seconds, a door lock check will occur and the Anti-Theft system will ARM. Also, if any door is unlocked a LOCK sequence will occur.)
