    What year is your vehicle?

    HCX

    Automatic Transmission Only

    Key Fob Kit Required!

    Why are key fobs mandatory?

    This vehicle does not support 3xlock start, it is because the OEM key fob (original key fob) goes dead (stops working) when the vehicle ignition is on (such as when the engine is running). This means, that if you were to use 3xlock start, you would have no way to open the doors (keyless entry) while the engine was running, as the OEM key fob goes dead. Hence, the requirement for the aftermarket key fob.

    This is not a big deal though, as in most cases where 3xlock start is not supported, you can leave the OEM key fob at home, and simply switch over to using the aftermarket key fob for all functions (such as lock/unlock/trunk release/remote start & stop. Also, you will gain increased range by using the aftermarket key fob.
