But I thought a physical key had an ID code that had to be recognized by the immobilizer system in order to start the car? So if someone filed down a key blank, or another Subaru's key, it should not start the car without the ID code. No? For this reason I thought, perhaps mistakenly, that a physical key was more secure because it had both physical and electronic security features where as a push-to-start fob is only electronic.Someone who is less technically inclined can file down a key to use in the ignition if they don't know how to hot wire the ignition or extend the range on a push to start key. It takes more knowledge to know how to hot wire an ignition and even more knowledge and a device to extend the range and trick the car into thinking the key fob is in the car, if that makes sense.
