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 key. They communicate with one another through radiofrequency signals.

This helps keep vehicles secure by stopping hotwiring. Smart keys also transmit unique encrypted signals that prevent 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 on the door or trunk. Many modern vehicles also offer an option that allows you to start your engine from a distance. This is especially useful when you're bringing groceries in or transporting equipment, passengers, or passengers.

This technology is designed to help prevent vehicle theft. Instead of sending only one frequency signal as a standard key fob smart keys send out an array of encrypted signals to a car's embedded antennas when you approach it. How Stuff Works Electronics explains that this is a way to prevent other cars from receiving and responding the same signal.

Certain manufacturers also incorporate a computer chip inside the vehicle that detects the unique fingerprint of every key. This helps to ensure that only authorized users are using it. This can be helpful should you lend your vehicle to family and friends.

Some smart keys also store user settings so that mirrors, seat and steering wheel adjustments, as along with stereo presets can be set automatically when the key is within reach of the vehicle. Some smart keys may also be programmed to stop the vehicle from exceeding the speed limit when it is started using that key. This is a great way to protect new drivers and it's beneficial if you have children in the back.

Security

Traditionally, car keys have been cut out of metal and used to unlock the ignition. Smart keys eliminate this requirement. Smart keys come with a chip which sends an electromagnetic signal from the antenna to your car. The car detects this signal when the driver presses the button on the trunk release or door handle. It is now impossible to lock the keys inside your vehicle.

The signal sent by the smart key to your vehicle is secured so that only you are able to use it. A majority of models also shut down the engine when the vehicle hasn't been running for a few minutes. This feature is particularly useful when you're in a risky zone or need to leave the vehicle for reasons of any kind, like at a petrol station.

A lot of systems also have a backup system for opening and starting the car if the battery of the smart keys runs out while riding. The backup method involves putting the key in a slot, or holding it close to a certain area in the cockpit in which energy is transferred to an electric motor. Some manufacturers also have an key blade that is an emergency mechanical lock in the key which can be used to open the trunk and start the car in case of need.

Battery Life

The majority of newer cars have keyless entry systems and push-button starters. These are controlled by a smart fob which communicates with the car through proximity technology. These systems use a tiny transmitter, powered by a lithium coin-sized battery. As with all batteries it will eventually need replacement.

Most smart batteries for key fobs last for several years However, that doesn't mean they can't lose power and stop working suddenly. If the fob's battery is dead you won't be able unlock or start your car even when you place it close to the front door.

It's not unusual for the transmitter of the smart key to drain the battery. The smart key transmits an alert each when you press the button. However, the majority of the time, it does nothing. The battery of a smart key is enough to last for a long time. lock/unlock signals.

The fob will also drain the battery If you keep it in close proximity to other devices that emit electromagnetic fields, for example phones and computers. These gadgets emit magnetic fields of their own which can cause interference and slow down the fob's transmitter. In some instances the fob might cease to function entirely in the event that the fob is too close to these devices, according to RepairPal.

As opposed to the traditional car key, a smart key makes use of technology to control the locks on your vehicle and perform some other functions. It works by sending a signal to antennas placed inside and outside your vehicle. They detect the fob's signal and communicate with the car's computer. The car interprets the signal, and allows you to begin or open it without a physical key.

New cars are loaded with high-tech electronic features, and the fob has become the hub for many of these functions. The most obvious features include locking and unlocking your vehicle, remote starting and chirping to help you locate your car in a parking space. Some fobs allow you to store specific settings for various drivers and open windows remotely and sunroofs.


The transmitter itself is a sophisticated device with an integrated circuit board and it is susceptible to damage through repeated use or exposure to cold or heat. The transmitter can break if dropped or banged. The battery's contacts can become bent.

These problems can be hard to determine and solve. You can try using your phone to bypass the issue and see if that helps however it's always a good idea to keep a spare key inside your pocket in a case.
