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 to start engines without a driver having to insert a physical key. They communicate with one another by using radiofrequency signals. Apart from that, it assists in keeping cars safe by stopping attempts to hotwire. Smart keys broadcast unique encrypted signals that prevent them from being accessed by other vehicles. Convenience Instead of having to insert a key into an ignition slot to lock and unlock your vehicle simply by touching the handle on your door or trunk. Modern vehicles often have an option that allows you to start your engine remotely. This is particularly helpful when you're bringing groceries in or transporting equipment and passengers. This technology is designed to to prevent theft of vehicles. Smart keys transmit encrypted signals instead of a single frequency like a standard keyfob. This stops other vehicles from being able to receive and respond to the same signal, explains How Stuff Works Electronics. Furthermore, some manufacturers utilize a computer chip within the vehicle to recognize the unique fingerprint of each key, which ensures that only authorized drivers are using it. This can be beneficial when you loan your car to family and friends. Certain smart keys also store user preferences, so that seat, mirrors, and steering wheel adjustments, as along with stereo presets can be set automatically when the key is within reach of the vehicle. To make things easier, some smart keys can be programmed to stop the vehicle from exceeding a speed limit when it is activated with a specific key. This will help keep new drivers safe and helpful if you have young children in the back of the vehicle. Security Traditionally, keys were cut from metal to open the ignition. With the advent of smart key technology however, this is no longer necessary. smart keys cars are equipped with an exclusive chip that sends a signal to the car's antenna. This signal is acknowledged by the vehicle when the driver presses a button on the handle of the door or trunk release. It is now impossible to lock the keys in your vehicle. The signal that the smart key transmits to your car is encrypted, which means that only the owner of the car can use it. The majority of models will also turn off the engine if the car hasn't been started for several minutes. This feature is particularly helpful when you are in an unsafe area or you have to get out of your vehicle for any reason. There are many systems that also have an alternative system for opening and starting the car if the battery of the smart key runs out during a ride. The backup system involves inserting the key in a slot or holding it close to a certain location in the cockpit, which transfers energy to an electric motor. Some manufacturers also have an emergency mechanical key blade inside the key that can be used to open the trunk and start the car if needed. Battery Life Many newer cars have keyless entry systems as well as push-button starters. They are controlled by a smart fob that communicates with the car via proximity technology. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. It will eventually require to be replaced as with any other battery. Although smart key fobs are designed to last for years but they may suddenly lose power. If the fob is dead it won't be able unlock or start your car even in the event that you put it near the front door. It's not unusual for the transmitter inside a smart key to drain the battery. The smart key transmits a signal every time you press the button. But most of the time it does nothing. The battery of a smart key is large enough to last for several years of lock/unlock signals. The fob also tends to drain the battery if you keep it close to other devices emitting electromagnetic fields, such as phones and computers. These gadgets emit their own magnetic fields, which can interfere and slow down the fob's transmitter. In some instances the fob might stop working altogether in the event that the fob is too close to these devices, as per RepairPal. Maintenance Contrary to the traditional metal car key, a smart one makes use of technology to control the locks on your vehicle as well as perform other functions. It functions by sending an electronic signal from the fob to antennas inside and outside the vehicle. These antennas sense the signal and communicate with your car's computer. The car responds to the signal and allows you to open and start it without having to use the physical key. New cars are loaded with high-tech electronic features and the fob has become a hub for many of these functions. The most obvious uses include locking and unlocking your car, remote starting and chirping noises to help you locate your vehicle in a parking space. Some fobs even let you store specific settings for different drivers, and also open windows remotely and sunroofs. The fob itself is a complex device with an integrated circuit board and it is prone to being damaged by hard use or exposure to heat or cold. The transmitter can be broken when it's hit or dropped or smashed. The battery contacts can also become bent. These issues can be difficult to diagnose and fix. You can use your smartphone to solve this issue and check if it is working. However it is important to keep an extra key in your pocket in case. You can purchase an ordinary smart key replacement that costs up to 70% less than OEM keys and comes with a three-year warranty.
