Everyone else (at least Toyota with my parents’ 2006 Sienna) seems using Microchip Keeloq which is far more secure.

Some dope will come up with the idea of calling them in for service in the middle of the night so owners aren’t inconvenienced, and all the thieves have to so is some GPS spoofing so they’re waiting with covered trucks in a lot up the street… that’s if they can’t screw directly with cellular control of them with a stingray or micro cell type device.

It’s using the fob to lock when leaving the car that is problematic – now an attacker could leave a device in a parking lot that will unlock a vehicle 5 minutes after it is locked – e.g. more than enough time for the owner to have walked away.

Just a thought.
