Car Alarms: Marksman M12 Alarm, nav system, flip switch

Question
While working on installing a new Nav system (alarm off).  The Alarm chirped once and cut off the ignition.  Vehicle will not start, I tried resetting alarm and nothing.

System must have reset, alarm on/off chirp is different but, ignition still isn;t working.

How can I reset alarm system and re-engage ignition cutoff??

Answer
Hmmmm,
Make sure you do the procedure correctly.
Might have missed a step:

KEY ON JUST BEFORE CRANKING ENGINE.
PRESS IN AND HOLD UNTIL YOU GET A RESPONCE
FROM THE ALARM.
KEY OFF.

This should toggle the alarm in and out of
valet/override.

If toggle type switch.
KEY ON, FLIP SWITCH, KEY OFF,
START THE CAR.

I hope this solved it for you.
