bbf2530 Posted August 8, 2010 Report Share Posted August 8, 2010 (edited) what is the difference between the passive anti-theft and perimeter alarm? thanks for help. Hi kev. :D Simplified explanations: - Perimeter Alarm is the factory alarm system on most Ford vehicles. When armed, the perimeter alarm will sound if a door, trunk, hood etc. is opened in an unauthorized manner (essentially, without first disarming the system by using the remote keyfob, key in door, keypad etc). - Passive anti-theft is an ignition/engine immobilizer. The Ford key has a "transistor/chip" embedded in it. That key/chip is programmed to your vehicle. If anyone tries to start the car without that programmed key/chip present, the vehicle will not start. But it will not set off an alarm. Think of it this way: The Perimeter Alarm works to prevent/scare a potential thief from gaining unauthorized entry to your vehicle by using noise and lights (the alarm). The Passive Anti-Theft system(PATS) works to prevent them from unauthorized starting of your vehicle by immobilizing the ignition/engine, once they are already inside. Our Owners Manuals have additional in-depth information if you wish to learn more about the systems. Good luck. :beerchug: Edited August 8, 2010 by bbf2530 Quote Link to comment Share on other sites More sharing options...

Lex Talionis Posted August 9, 2010 Report Share Posted August 9, 2010 and from experience, I can tell you that when you put in a key that is not chipped to your car, you can turn the power on, but no turn over. Just FYI. Quote Link to comment Share on other sites More sharing options...
teagueda Posted August 21, 2011 Report Share Posted August 21, 2011 thanks!!! My new 2011 Ford Edge Sport did not come with a factory installed perimeter alarm. I purchased the VSS GEN2 device to turn on the perimeter alarm but had it later removed because it altered the procedures for using the factory installed remote start. I had to unlock the car first then press the lock button then double press the remote start button. The distance to unlock is very limited so the feature was useless.
