Is there a way (reprogramming the GEM, or maybe a plug-in module) to somehow enable the factory perimeter alarm functionality on a late 06 - 07 Focus with OEM remote keyless entry?
I know it was an available option on he cars, and looking at the schematics, the keyless entry, power locks, door sensors, lights, and horn are all controlled by the GEM. Also, the car already has the hood sensor. So, technically, everything necessary for the perimeter alarm is already there.
I have heard for GM cars, it it is as simple as changing a setting accessible to dealers on OBD2...
Any thoughts appreciated
P.S. The alarm available from Ford Accessories is virtually an aftermarket one, and requires tapping in (soldering) to existing wires:
