Not even James Bond has one of these: a watch that performs the functions of a keyless entry fob for your car. Developed by (or for) Chinese car manufacturer BYD, the gadget is made only for the F8 model. Press the top button on the right, and the car is locked, press the bottom button, the car is unlocked.

The watch also has a starter function, but it's not labeled on the bezel like the others. Since it has a manual movement, you don't need to worry about a battery going dead as long as you wear the watch... and move. No word on whether you need to wind it in case you don't wear it. But come on now, it's not like you could stay away from your BYD F8 long enough for the watch to stop, is it? And as the brochure states, it even tells time -- which is not a bad thing for a watch.

We all take for granted that the little plastic key fob in our pockets is a secure way of locking and unlocking our car doors. But a group of researchers say they have devised a way to relatively quickly decipher your car's unique code and totally pwn everything inside it.

The group says most car manufacturers are still using KeeLoq, an encryption technology developed in the 1980s, for their keyless systems. It's pretty good technology, they say, that normally would take 100 computers several decades to break. But by listening in to communication between key fobs and cars, the researchers say they can narrow down the number of code options and, instead of say, 50 years, they're in your car in about 50 minutes.

While they admit it's much easier and quicker to break into a single car with an old-fashioned baseball bat, their new, high-tech method has one merry advantage. They lay out a scenario of a packed holiday-shopping-season parking lot. Parked in the center, a van full of snooping equipment and computers listens to hundreds of keyfobs wirelessly locking car doors. Then, with little more than a few keystrokes and an hour or so later, the crooks sing "Jingle Bells" to the tune of hundreds of car doors opening in harmony.

The group claims its intentions aren't to ruin everybody's Christmas morning, but instead hopes car manufacturers wake up and update their 20-year-old technology. So this holiday season, remember to keep your valuables and packages hidden well, and lock your cars' doors the old-fashioned way.

The research group's short press release is available after the jump.
