What is a Smart Key Car Key? Sometimes referred to as keys that are in proximity also known as key fobs, keys or remote keys, smart keys function to unlock doors and start engines without having to insert an actual key. They communicate via radiofrequency signals. Apart from that, it helps protect vehicles by blocking attempts at hotwiring. Smart keys emit unique encrypted signals that block access to other vehicles. Convenience Instead of inserting a key into an ignition slot, you can lock and unlock your vehicle by simply pressing the handle of the door or trunk. A lot of modern cars also have the ability to remotely start your engine. This is particularly helpful when you're bringing groceries in or transporting passengers and equipment. This technology is intended to deter theft of vehicles. Smart keys transmit encrypted signals instead of a single frequency like a normal keyfob. This prevents other cars from being able to receive and respond to the same signal, explain how Stuff Works Electronics. Additionally, some companies employ a computer chip inside the vehicle to identify the unique fingerprint of each key, which makes sure that only authorized drivers are using it. This can be helpful in the event that you lend your car to friends and family members. Certain smart keys also store user settings so that mirrors, seat, and steering wheel adjustments as also stereo presets may be automatically set when the key is within range of the vehicle. Some smart keys can also be programmed to stop the vehicle from crossing the speed limit when it is started using that key. This is a great way to ensure that new drivers are safe and is a good idea when you have children in the back of the vehicle. Security Traditionally keys were made of metal to unlock the ignition. Smart key technology eliminates this need. Smart keys are equipped with a specific chip that sends the signal to the car's antenna. The vehicle recognizes this signal when the driver presses on the trunk release or door handle. smart car key reprogramming is now impossible to lock the keys inside your vehicle. The smart key's signal to your vehicle is encrypted, ensuring that only you are able to use it. In addition, most models will shut off the engine if the vehicle is not started within the last 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 gas station. Many systems also have an alternative system for opening and re-starting the car if the battery of the smart key goes out while you are on a ride. The backup method is to insert the key into a slot or holding it near a particular space in the cockpit where the energy is transferred to an electric motor. Certain manufacturers also include an emergency mechanical key blade in the key that could be used to open the trunk and start the car in case of need. Battery Life Many newer cars have keyless entry and push button starting systems which are controlled by a key fob that uses proximity technology to communicate with the car. These systems are powered by a tiny transmitter that is powered by a coin-sized lithium battery. Like all batteries that will eventually require replacement. The majority of smart key fob batteries last several years, but that doesn't mean they'll never go out of power and stop working suddenly. If the fob battery is dead, you won't have the ability to unlock or start your car in the event that you put it close to the front door. It is not uncommon for the transmitter of a smart key to drain the battery. It sends a signal to the car each time you press one button, however most of the time, the smart key is not doing anything. A single signal to lock or unlock takes just a tiny portion of the fob's battery and that's several years worth of signals worth of battery life for the average smart key battery. The fob can also drain the battery when it is located near other devices which emit electromagnetic field like phones and computers. These devices emit magnetic fields of their own that can interfere with and slow down the fob's transmitter. In some instances the fob might cease to function entirely if the fob is left too close to these devices, as per RepairPal. Maintenance In contrast to the traditional car key, a smart key uses technology to manage the locks on your vehicle as well as perform other functions. It operates by transmitting a signal through antennas situated inside and outside of your vehicle. They detect the fob's signals and communicate with the car's computer. The car interprets the signal, which allows you to turn it on or open the door without a physical key. The fob is now a hub of numerous electronic features found in modern vehicles. The most obvious uses are locking and unlocking your car, remote starting and chirping sound to help you locate your car in a parking lot. Certain fobs let you store various settings for different drivers, and can even remotely open windows as well as the sunroof. The transmitter itself is a specialized device that includes an integrated circuit board, and it could be damaged through repeated use or exposure to heat or cold. The transmitter may be damaged if it is hit or dropped. The battery contacts may become bent. These problems can be hard to diagnose and fix. You can use your smartphone to get around this issue to see if it works. However, you should always keep an extra key in your pocket in a case. You can purchase an equivalent replacement for the majority of OEM smart keys, which can cost up to 70% less and comes with a three-year better-than-OEM guarantee.
