Is it possible to disarm the factory alarm in a 2007 mazda 3 without unlocking the doors?
I got a compustar pro 900 installed and the car unlocks before the start and I had to set it up to lock after but it stays unlocked for an easy 30 seconds every time I remote start it...

Thanks!

according to directechs, using the factory alarm disarm wire will also unlock the doors at the same time

Power Unlock - GREEN/ RED (-) Straight ground to unlock @ DKP
Power Lock - GREEN/ RED (-) through 1k ohm resistor @ DKP

**use relays, the outputs on your aftermarket system doesnt have the current to lock/unlock all doors.**

Alarm Disarm - BLACK/ WHITE (-) @ DKP ****
Alarm Arm - BLACK/ BLUE (-) @ DKP

****disarm requires double pulse****
