Bypassing the alarm does not work anymore because the entire system is integrated. Remove the negative battery cable and let the car sit for thirty minutes. Then reconnect it and unlock the drivers door with the key or remote and the system should be reset.

Here is a guide as well:

Please let us know what happens.

Cheers, Ken
