I had an attempted theft on my Raptor last year. They broke the door handle and got in and disabled the horn as well. Thankfully my Raptor requires a physical key to start the vehicle. When they broke in, the immobalizer went off and they had 10 seconds to put in the key to disable it. I saw in my security camera that they saw the message and they existed and thankfully didn't steal my truck.

I now block it in my driveway with a beater car and remove the battery from my beater car lol. Kind of a pain in the ass but whatever. I will be moving soon so I will have a garage.

I have a Cobb tune on my Raptor now and there is an anti theft map on it(all Cobb tuners have this), it works by having a map that was designed to not allow the vehicle to start. The Vehicle dies instantly once RPMs increase over 500. This map is based on stock parameters with the rev limiter set below idle which prevents vehicle from starting.
