What is a Smart Key Car Key? Smart keys are also referred to as proximity keys or key fobs. They function to unlock doors and start engines without a driver having to insert a physical keys. They communicate with radiofrequency signals. This helps to keep vehicles safe by not allowing hotwiring. Smart keys also transmit unique encrypted signals to stop them from being used by other vehicles owned by drivers. Convenience Instead of putting keys into an ignition slot to lock and unlock your car by simply touching the handle of the door or trunk. Modern vehicles often have the ability to start your engine from a distance. This is especially useful if you are bringing groceries in, or transporting passengers or equipment. This technology is designed to stop theft of vehicles. Instead of transmitting a single frequency signal like a regular key fob, a smart key sends out an array of encrypted signals to the car's embedded antennas as you come close to it. This stops other vehicles from receiving and responding to the same signal. explain how Stuff Works Electronics. Some manufacturers also use a computer-chip in the vehicle which recognizes the unique fingerprints of each key. This helps to ensure that only authorized users are using it. This is helpful should you lend your vehicle to family and friends. Some smart keys also store user settings so that mirrors, seats, and steering wheel adjustments, as along with stereo presets can be set automatically when the key is within the range of the vehicle. Some smart keys can be programmed to stop the vehicle from exceeding the speed limit once the key is used to start it. This can help keep unexperienced drivers safe, and is particularly beneficial for families with young children in the back of the vehicle. Security Traditionally keys for cars were cut from metal and used to unlock the ignition. With the advent of smart key technology, it is no longer a requirement. Smart keys have a specific chip that transmits an electromagnetic signal from the antenna to your car. The vehicle recognizes this signal when the driver presses the button on the trunk release or door handle. It is now impossible to lock the keys in your vehicle. The signal sent by the smart key to your vehicle is encrypted, ensuring that only you can access it. In addition, most models will turn off the engine if the car was not launched in the past few minutes. This is especially useful if you're in an unsafe zone or need to leave the vehicle for any reason, such as at a petrol station. Furthermore, if the smart key battery runs out during a ride, a lot of models have a backup system of opening and starting the vehicle. The backup method is to insert the key in a slot or holding it close to a certain area of the cockpit where energy is transferred to an electric motor. G28CarKeys have a mechanical key blade that can be utilized in a situation of emergency to open the trunk or to start the car. Battery Life Most newer cars come with keyless entry systems and push-button starters. They are controlled by a smart fob that communicates with the car through proximity technology. These systems use a tiny transmitter that is powered by a coin-sized lithium battery. Like all batteries that eventually requires replacement, this one too will need replacement. Most smart key fob batteries last for several years However, this doesn't mean that they won't go out of power and stop working abruptly. A dead key fob means you can't unlock or start the car even when you hold it near the front door. The key fob's light flashes. It is not unusual for the sensor of a smartkey to drain the battery. The smart key emits an alert each when you press a button. However, most of the time, it doesn't do anything. The battery of a smart key can be used to power several years of unlock and lock signals. The fob is also prone to drain the battery if you keep it close to other devices that emit electromagnetic fields, such as phones and computers. These devices emit magnetic fields of their own which can cause interference and slow down the fob transmitter. RepairPal reports that the fob can stop working if it is placed too close to the gadgets. Maintenance Contrary to the traditional metal car key, a smart one uses technology to manage the locks on your vehicle and perform other functions. It operates by sending a signal to the antennas located inside and outside your vehicle. They detect the fob's presence and communicate with the car's computer. The car then interprets the signal and allows you to open or start it without the physical key. The fob is now a center of numerous electronic features on new automobiles. The most obvious are locking and unlocking, remote starting and chirping sounds that assist you in finding your car in a parking spot. Certain fobs let you save different settings for various drivers, and remotely open windows and the sunroof. The transmitter itself is a specialized device with an integrated circuit board and it is susceptible to damage when exposed to cold or hot. The transmitter can break in the event of it being dropped or banged and the battery contacts may also be bent. These issues can be difficult to determine and fix. You could try using your phone to solve the problem and see if that helps, but it's always a good idea to keep a spare key in your pocket to use in case. You can buy an ordinary smart key replacement that is up to 70 percent less than OEM keys and comes with a three-year warranty.
