What is a Smart Key Car Key?

Smart keys are also known as proximity keys or key fobs. They function to unlock doors and start engines without a driver having to insert physical keys. They communicate via radiofrequency signals.

In addition, it helps protect vehicles by stopping hotwiring attempts. Smart keys also broadcast unique encrypted signals to prevent them from being used by other vehicles owned by drivers.

Convenience

Instead of putting a key into an ignition slot instead, you can lock and unlock your vehicle by simply touching the handle of the door or trunk. Many modern vehicles also offer a feature that allows you to remotely start your engine. This is particularly useful when you're taking groceries home or transporting passengers and equipment.

This technology is designed to stop theft of vehicles. Instead of transmitting a single frequency signal, similar to a normal key fob it sends out an array of encrypted signals to the car's embedded antennas as you walk towards it. This stops other vehicles from being able to receive and respond to the same signal. This explains How Stuff Works Electronics.

Certain manufacturers also incorporate computers in their vehicles which recognizes the unique fingerprints of each key. This makes sure that only authorized users are using it. This can be beneficial if you lend your car to family members or friends.

Certain smart keys can be set up to prevent the vehicle from crossing the speed limit once it is started using that key. This can help keep novice drivers safe and can be helpful if you have young children in the back of the vehicle.

Security

Traditionally keys were made from metal to unlock the ignition. With smart key technology it is no longer necessary. Smart keys come with a chip that transmits signals from the antenna to your car. The car smart key programming near me detects this signal when the driver presses the button on the trunk release or door handle. It is now impossible to lock your keys into your vehicle.

The signal that the smart key sends to your car is encrypted, meaning that only the owner is able to use it. A majority of models also shut down the engine when the car isn't started for some time.

The backup system involves inserting the key into an opening, or keeping it close to a specific location in the cockpit, which transfers energy to an electric motor. Certain manufacturers offer a mechanical key blade that can be utilized in a situation of emergency to open the trunk or start the car.

Battery Life

Most newer cars come with keyless entry systems and push-button starters. They are controlled by a smart fob which communicates with your car using proximity technology. These systems use a tiny transmitter powered by a lithium coin-sized battery. Like all batteries it will eventually need replacement.

Although smart key fobs are designed to last for many years however, they can suddenly lose power. If the fob battery is dead, you won't be able to unlock or start your car if you hold it up near the front door.

It is not uncommon for the sensor of a smartkey to drain the battery. The smart key emits the signal each time you press the button. However, most of the time, it doesn't do anything. One single lock/unlock button takes up a miniscule amount of the battery power in the fob and that's many years of signals' worth of battery life in an average smart key battery.

The fob is also prone to drain the battery when you keep it close to other devices that emit electromagnetic fields, like phones and computers. These gadgets produce their own magnetic field which could interfere with the fob's transmitter, causing it to work slower. RepairPal states that the fob may not function if it's placed too close to the gadgets.

Maintenance

As opposed to the traditional car key, a smart key for smart car utilizes technology to control the locks on your vehicle and perform other functions.
