Beginning in the ’04 model year, General Motors will be the first automaker to offer a remote vehicle starter ... the fob when Dad is in the garage working on the car, the system won’t start ...

An engine block ... that car to be warmed up, keep your doors locked and use a remote starter instead of leaving your keys in your car -- and definitely don't just leave it in your garage.

The handheld devices you use to open your car, otherwise known as key fobs, have evolved greatly since the 1950s when remote control technology was first used to open garage doors (via Mental Floss).
