A remote keyless system allows for operation of a vehicle from a distance through a wireless transmitter. It consists of a control unit in the vehicle and a key fob with buttons for system functions. It can unlock doors, open trunks, and start the engine from a distance. It is available as an aftermarket accessory and can protect the finish of the vehicle.
A remote keyless system is a device that allows operation from a distance of vehicle functions through the use of a unit that sends signals to the car from a wireless transmitter. The device works through a control unit in the vehicle and a transmitter commonly known as a key fob or key fob that has buttons to activate system functions. One common type is a remote keyless entry system for unlocking car doors and opening the trunk or cargo area. Another type called a remote keyless start system is capable of starting a car using the wireless transmitter.
The device known as a remote keyless system actually consists of two separate units. One is a control unit placed in the vehicle and connected to the systems with which it will interface and control. The other is a wireless transmitter known as a remote that sends signals to the control unit. The remote usually has a separate button for each function the keyless remote system can perform, and can be a separate unit or built into the car’s ignition key in a factory-fitted system. Some systems can work from up to 1,000 feet (0.3 km) away in ideal conditions, and car owners can often use them from inside their homes.
Most new vehicles are offered with the option of a remote keyless entry system installed; the devices are also available for purchase as aftermarket accessories. This type of remote keyless system can usually unlock car doors and open the trunk or cargo area with the touch of a few buttons, allowing for easy entry, loading, and unloading. Many vehicle owners like the added convenience the system offers because it eliminates the need to physically insert a traditional key into the door lock. The system can also help protect the finish in the area near the door handle from key scratches and reduce wear on the lock barrel.
Another type of remote keyless system that is increasing in popularity operates the vehicle’s ignition. Known as a remote keyless start system, this device can start the vehicle from a distance, allowing the engine to warm up and the interior to reach a comfortable temperature before getting inside. The engine starts using a button on the remote, but the car cannot be started for safety reasons. To start the car and drive it, the owner must either insert the actual key into the ignition or properly operate a push-button start system.
