SAN FRANCISCO (AP) -- Could thieves take your car just by texting?
Security experts say it's possible. Researchers from iSec Partners recently demonstrated a means of hacking into a car alarm system by texting it to unlock the doors and start the engine.
It's because many car alarms and GPS devices are connecting to cellular phone networks.
Stealing a car this way, while possible, is not easy. Hackers would have to know which phone number opens which car, and cars without alarms are generally easier to steal.
