Since they use an Infrared signal rather than a pattern on the key to start the car, the key runs out of juice real quick- when I test drove the C230K, the dealer said the key'll last about a year or so before you have to replace the battery. He maybe wrong, but a battery running out anywhere near that time frame is messed up. I like the auto-recharge feature of the new BMW keys.
