What is a Smart Key Car Key?
Also known as keys that are in proximity, key fobs or remote keys, smart keys are used to unlock doors and start engines without having to insert an actual key. They communicate by radiofrequency signals.
This helps keep cars secure by not allowing hotwiring. Smart keys also broadcast unique encrypted signals to prevent them from being used by vehicles of other drivers.
Convenience
You can lock and unlock your vehicle without needing to insert the key into the ignition slot. Simply touch the handle on the door or trunk. A lot of modern cars include a feature that permits you to start your car wirelessly. This is especially useful when you're bringing groceries in or transporting passengers and equipment.
This technology is intended to protect against theft of vehicles. Instead of transmitting a single frequency signal, like a regular key fob does, a smart key sends out an array of encrypted signals to the car's embedded antennas when you come close to it. This prevents other cars from receiving and responding to the same signal, explain how Stuff Works Electronics.
Some manufacturers also use computers in their vehicles that detects the unique fingerprints of each key. This can help ensure that only authorized users use it. This is useful if you lend your car to family members and friends.
Certain smart keys also save user preferences, allowing seat, mirrors, and steering wheel adjustments, as along with stereo presets can be automatically set when the key is within reach of the vehicle. Some smart keys may also be set up to prevent the vehicle from crossing the speed limit when the key is used to start it. This is a great method to protect new drivers and it's recommended if you have children in the back of the vehicle.
Security
Traditionally keys for cars have been made from metal and used to unlock the ignition. Smart keys eliminate this need. Smart keys are equipped with an exclusive chip that sends a signal to your car's antenna. The car 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 that the smart key sends to your car is encrypted, meaning that only the owner is able to use it. In addition, most models will shut off the engine if it hasn't been started in the last few minutes. This feature is particularly useful when you are in an unsafe location or you need to leave your vehicle for any reason.
In addition, if the smart key battery fails during a trip, many models have a backup system to open and start the vehicle. The backup system typically consists of placing the key in the slot or placing it near a specific area of the cockpit, which transfers energy 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 start systems, controlled by a smart key fob that utilizes proximity technology to communicate with the car. These systems are powered by a small transmitter that is powered by a lithium coin-sized battery. Like all batteries that eventually requires replacement, this one too will need replacement.
The majority of smart key fob batteries last for a long time, but that doesn't mean they can't 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 near the front door.
It's not uncommon for the transmitter in a smart key to drain the battery. The smart key sends an alert each time you press a button. But smart car keys replacement of the time, it doesn't do anything. A single lock/unlock signal takes just a tiny portion of the fob's battery, so there is easily many years of signals' worth of battery life for the average smart key battery.
The fob can also drain the battery if you place it close to other devices emitting electromagnetic fields, for example phones and computers. These devices create their own magnetic field which can interfere with the fob's transmitter, causing it to run slower. In some instances the fob might cease to function completely in the event that the fob is too close to these devices, according to RepairPal.
Maintenance
Contrary to the traditional metal car key, a smart one uses technology to manage the locks on your vehicle and perform some other functions. It works by transmitting a signal through antennas placed inside and outside your vehicle. These antennas detect the fob's signal and connect with the car's computer. The car interprets the signal, which allows you to turn it on or close it without having to use the physical key.
New vehicles are loaded with advanced electronic features and the fob is now an interface for many of these functions. The most obvious features are locking and unlocking your vehicle, remote starting and chirping to help you locate your vehicle in a parking spot. Some fobs allow you to store specific settings for different drivers, and also open windows remotely and sunroofs.
The fob is a complex electronic device that has an integrated board that can be damaged if it is placed in a position that is too harsh or exposed to extreme cold or heat. The transmitter can break if it is damaged by a fall or a bang or smashed. The contacts on the battery can become bent.
These issues can be difficult to identify and fix. You can try using your phone to bypass the problem and see if that helps however, it's a good idea to keep a backup key in your pocket to use in case. You can buy a generic replacement for the majority of OEM smart keys, which costs up 70% less and is backed by a three-year more than OEM guarantee.
