In addition, it helps protect vehicles by preventing attempts at hotwiring. smart forfour key programming keys also broadcast unique encrypted signals that prevent them from being used by other vehicles driven by drivers.

Convenience

You can lock and unlock your vehicle without inserting the key into the ignition slot. Simply tap the handle on the door or trunk. Many modern vehicles also offer a feature that allows you to start your engine remotely. This is especially useful if you are bringing in groceries or transporting passengers or equipment.

This technology is designed to deter theft of vehicles. Instead of sending a single frequency signal like a traditional key fob, a smart key sends out a series of encrypted signals to the car's embedded antennas when you come close to it. How Stuff Works Electronics explains that this stops other vehicles from receiving and responding the same signal.

Some manufacturers also use an electronic chip in the vehicle that detects the unique fingerprints of each key. This can help ensure that only authorized users use it. This is particularly useful in the event that you lend your car to family members and friends.

This is a great way to keep new drivers safe, and it's also recommended when you have children in the back.

Security

In addition, if the smart key battery runs out during a trip, many models have a backup system of opening and starting the vehicle. The backup system typically involves placing the key in a slot or holding it in a certain area of the cockpit to transfer energy to an electric motor. Some manufacturers also have an emergency mechanical key blade in the key that can be used to open the trunk and start the car in case of need.

Battery Life

Most newer cars have keyless entry as well as push-button starting systems which are controlled by a key fob that utilizes proximity technology to communicate with the car. These systems are powered by a small transmitter which is powered by a lithium coin-sized battery. Like any other battery that eventually requires replacement, this one too will need replacement.

Although smart key fobs are made to last for several years however, they can suddenly lose power. A dead key fob means that you won't be able to lock or start your car, even if you put it near the front door. The key fob's light blinks.

A single signal to lock or unlock takes only a fraction of the fob's battery and, therefore, there's several years ' worth of signals' worth of battery life in an average smart key battery.

The fob is also prone to drain the battery If you keep it in close proximity to other devices that emit electromagnetic fields, like phones and computers. These gadgets emit their own magnetic fields which can interfere with and slow down the fob transmitter. In certain cases the fob could be unable to function if the fob is left too close to these devices, as per RepairPal.

Maintenance

Smart keys differ from traditional keys made of metal in that they utilize technology to control the security of your vehicle as well as perform other functions. It works by transmitting a signal to antennas placed inside and outside your vehicle that detect the fob's presence and communicate with the car's computer. The car interprets the signal, permitting you to start or open it without the physical key.

New cars are loaded with the latest electronic technology, and the fob is now an interface for many of these functions. The most obvious functions include locking and unlocking your car, remote start and chirping noises to help you locate your vehicle in a parking area. Some fobs allow you to store various settings for different drivers, and can even remotely open windows and even the sunroof.

The fob itself is a sophisticated device with an integrated circuit board and it is susceptible to damage by hard use or exposure to heat or cold. The transmitter can be broken when it's dropped or banged, and the contacts on the battery can become bent.
