What is a Smart Key Car Key?

Also known as keys for proximity also known as key fobs, keys or remote keys, smart keys work to unlock doors and start engines without needing to insert the key. They communicate with each other through radiofrequency signals.

Apart from that, it helps protect vehicles by preventing attempts at hotwiring. Smart keys also broadcast unique encrypted signals to stop them from being used by vehicles of other drivers.

Convenience

You can lock and unlock your vehicle without having to insert the key into the ignition slot. Simply touch the handle of the door or trunk. Modern vehicles often have the ability to remotely start your engine. This is particularly useful if you're bringing in groceries as well as transporting passengers or equipment.

This technology is designed to stop theft of vehicles. Instead of sending a single frequency signal, as a standard key fob, a smart key sends out an array of encrypted signals to the car's embedded antennas when you come close to it. How Stuff Works Electronics explains that this prevents other cars receiving and responding the same signal.

Some manufacturers also include a computer-chip in the vehicle which recognizes the unique fingerprint of each key. This helps to ensure that only authorized users are using it. This is useful when you loan your car to family members or friends.

Some smart keys also store user preferences, so that mirrors, seat, and steering wheel adjustments, as well as stereo presets can be set automatically when the key is within reach of the vehicle. For added convenience, some smart roadster key programming keys can be set to prevent the vehicle from exceeding a speed limit once it has been activated with a specific key. This will help keep new drivers safe, and is particularly helpful if you have young children in the back of the vehicle.

Security

Traditionally keys for cars were made from metal and used to unlock the ignition. With smart key technology, however, this is no longer necessary. smart forfour key programming keys have a specific chip that sends a signal to your car's antenna. The signal is then recognized by the vehicle when the driver presses a button on the handle of the door or trunk release. It is now impossible to lock your keys into your vehicle.

The signal that the smart key transmits to your car is encrypted, which means that only the owner is able to use it. Additionally, the majority of 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 area or you have to get out of your vehicle for any reason.

In addition, if the smart key battery gets depleted during a ride, many systems come with a backup plan of opening and starting the vehicle. The backup method is to insert the key into an opening, or keeping it near a particular area of the cockpit where the energy is transferred to an electric motor. Certain manufacturers offer a mechanical key blade that can be used in an emergency to open the trunk or start the car.

Battery Life

The majority of modern cars have keyless entry systems and push-button starters. They are controlled by a smart fob that communicates with the car through proximity technology. These systems are powered by a small transmitter that is powered by a coin-sized lithium battery. It will eventually need to be replaced like any other battery.

Although smart key fobs are designed to last for several years but they may suddenly lose power. If the fob's battery is dead you won't have the ability to unlock or start your car even holding it near the front door.

It's not uncommon to find the transmitter in a smart key to drain the battery. It transmits a signal to the car every time you press an option, but the majority times, the smart key is doing nothing. One single lock/unlock button takes up a miniscule amount of the fob's battery power, so there is easily several years worth of signals' worth of battery life left in the average smart car key key battery.

The fob can also drain the battery if it is placed near other devices that emit electromagnetic fields, such as phones and computers. These devices emit their own magnetic fields that can interfere with and slow down the fob transmitter. In some cases the fob could cease to function completely in the event that the fob is too close to these devices, according to RepairPal.

Maintenance

Smart keys differ from traditional metal keys in that they use technology to control the locks on your vehicle as well as perform other functions. It functions by transmitting a signal from the fob to antennas inside and outside the vehicle. These antennas detect the signal and then communicate with your car's computer. The car responds to the signal and allows the user to open or start it without using a physical key.

New vehicles are loaded with the latest electronic technology and the fob is now an instrument for many of these functions. The most obvious ones are locking and unlocking, remote starting and chirping sounds to assist you in finding your car in a parking lot. Some fobs even let you save specific settings for different drivers, and also open windows remotely and sunroofs.

The fob is an elaborate electronic device with an integrated circuit board that can be damaged if it is placed in a position that is too harsh or exposed to extreme heat or cold. The transmitter could break if it's dropped or banged. The battery's contacts can become bent.

These issues can be difficult to determine and repair. You can try using your phone to avoid the problem and see if that helps however, it's always a good idea to keep a backup key in your pocket, just in case. You can buy an alternative to the majority of OEM smart keys for up to 70% less and comes with a 3-year, better-than-OEM guarantee.
