it is not possible by not disarming the alarm without unlocking. Try it first without unlocking. i did a 98 accord DX and without using factory disarm wires or unlock befor start, it worked fine. Also, why are you worried about the unlock-start-lock, its a process under 10 seconds. you do have the brake shut down wire... In programming program so it will pulse befor start. wire the factory arm and disarm wires with the lock and unlock. so to simplify, FAC ARM with LOCK and FAC DISARM to UNLOCK. Diode isolate both wires with the cathode band towards alarm unit.
