They also have features specifically designed to stop burglaries and vehicle theft, such as the panic button, which produces a sound to frighten away people who may be suspicious of thieves in areas that are isolated like underground garages with parking.

Key fobs can perform all of these functions by sending a radio transmission between the car key fob and the car using low-power wireless technology. This is an excellent convenience, especially for drivers who are constantly on the go and don't have time to spare car keys.
