Sounds like it about as easy to shutdown as Microsoft's SP2 firewall... 

Overwrite a file, it fails integrity checks and the firewall will fail
closed. There is something to add to a dropper program.

So effectively, you're unlocking the car doors because it is equipped
with a series of alarmsystems.  And even if the owner locks the car
doors manually, upon activation, the alarm system unlocks them again ?
