okay.... like this.... no need use extra remote, use back original alarm remote.
no effect to other any stuff.
1st, now ur car is unlocked. after this press the unlock then engine alarm will start the engine.
2nd, even if someone go in the car without the key, can press the acceleration pedal, but, the steering still locking.
3th, when going down from the car, 1) off key,close door, the engine still running, when u press the alarm remote to lock the centre locking, then the engine will turn off automatically. 2)off key, then engine still running, after close all door, then the engine will stop automatically. 3) off key, close door, lock centre locking, the engine still running, the engine will turn off automatically after 10second, just like turbo timer, but no need the timer.
