What Can a Smart Car Key Fob Do For You?

Mercedes introduced the first fobs in 1998. They are also referred to as smart keys, keyless entry, or keyless entry fobs. The fobs that are computer controlled are capable of performing a variety of functions like locking and unlocking the car or beginning it.
