Provided is a preprogrammed key fob system that allows a user to limit a vehicle top speed while the given key fob is being used to operate the vehicle. The system comprises a vehicle system and a navigation system, wherein the navigation system is disposed within the key fobs and the key fob is adapted to communicate with the vehicle system while in use. The navigation system of each key is utilized to capture the local speed limit of a given road, while a vehicle speed is programmed into the specific key to set a vehicle speed buffer above the local speed limit being traveled. The system therefore limits the user of a given key to a preset limit, which adapts in real-time based on the local speed limits and allows the owner of the keys to set the limits and to monitor the vehicle conditions using the system.
