Car Alarms: Alarm conflict, memory seats, key less entry

Question
We are adding a commando 550 to a 2007 Fusion, the fusion has factory key less entry which we will not be using, however the problem we haveis when we lock the doors with the commando it activates the panic alarm.  

Answer
Ok, you need to send a negative pulse to the factory
alarm disarm wire at the same instant that you
unlock the doors remotely. You do this by adding
a negative relay, fed by the unlock output on the 550,
then to the OEM wire (PURPLE/BROWN)

Meter this wire while turning the key in the driver door key cylinder.
The SJB (Smart Junction Box) is part of
the fuse/relay box under the driver side dash.

On vehicles with memory seats,
the factory alarm disarm wire is found
at the driver door module in the door.

That will solve this issue for you.

Good luck with it.
Nice car.
