What is a Smart Key Car Key?

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

This helps keep vehicles secure by not allowing hotwiring. smart key programing keys transmit unique encrypted signals that block them from being accessed by other vehicles.

Convenience

Rather than having to insert a key into an ignition slot to lock and unlock your car by merely touching the handle of the door or trunk. Many modern vehicles also offer the ability to start your engine remotely. This is particularly useful when you're taking groceries home or transporting equipment and passengers.

This technology is intended to prevent vehicle theft. Smart keys transmit encrypted signals instead of a single frequency, like a standard keyfob. This blocks other cars from being able to receive and respond to the same signal. This explains How Stuff Works Electronics.

Certain manufacturers also have a computer-chip in the vehicle that recognizes the unique fingerprints of each key. This ensures that only authorized users are using it. This can be helpful in the event that you lend your car to family and friends.

Certain smart keys also save user settings so that seat, mirrors, and steering wheel adjustments as well as stereo presets can be set automatically when the key is within the range of the vehicle. For added convenience, some smart keys can be configured to prevent the vehicle from exceeding a speed limit when started with that particular key. This is a great way to protect new smart car key drivers and also beneficial if you have children in the back of the vehicle.

Security

Traditionally, car keys have been cut from metal and used to unlock the ignition. With smart key technology however, this is no longer necessary. Smart keys are equipped with a chip that sends a signal from the antenna to your car. The signal is then recognized by the vehicle when the driver presses on the handle on the door or trunk release. It is now impossible to lock the keys in your vehicle.

The smart key's signal to your vehicle is secured so that only you have access to it. In addition, most models will stop the engine in the event that the vehicle is not launched in the past few minutes. This feature is especially useful if you're in an unsafe location or need to get out of the vehicle for reasons other than at a gas pump.

A lot of systems also have backup systems for opening and starting the car when the battery of the smart key runs out while you are on a ride. The backup system typically involves placing the key in the slot or putting it near a specific part of the cockpit. This transfers energy to an electric motor. Some manufacturers also have an emergency mechanical key blade hidden in the key that can be used to open the trunk and start the car in case of need.

Battery Life

The majority of modern cars have keyless entry and push button starting systems that are controlled by a smart keys for cars key fob, which uses proximity technology to connect with the car. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. It will eventually need to be replaced as with any other battery.

Although smart key fobs are made to last for many years but they may suddenly lose power. A dead key fob means you are unable to unlock or start the car, even if you keep it near the front door, and the key fob's light flashes.

It's not uncommon for the transmitter in a smart key to drain the battery. It sends a signal back to the car every time you press a button, but most of the time the smart key is not doing anything. The battery of a smart key is large enough to power several years of locking and unlocking signals.

The fob is also prone to drain the battery if you keep it close to other devices that emit electromagnetic fields, for example 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 might stop working altogether when the fob is placed too close to these devices, as per RepairPal.

Maintenance

Smart keys are different from traditional keys because they use technology to control the locks of your car in addition to performing other functions. It works by sending a signal to the antennas situated inside and outside of your vehicle. They detect the fob's presence and communicate with the car's computer. The car interprets the signal allowing you to start or close it without having to use the physical key.

The fob is now the hub of many electronic features that are now available in new vehicles. The most obvious ones are locking and unlocking, remote starting and chirping sound to aid in finding your vehicle in a parking lot. Some fobs allow you to store various settings for various drivers, and remotely open windows and the sunroof.

The transmitter itself is a sophisticated device that has an integrated circuit board, and it is susceptible to damage by repeated use or exposure to cold or heat. The transmitter could be damaged if dropped or banged. The battery contacts can become bent.

These issues can be difficult to pinpoint and fix. You can use your smartphone to overcome this issue to determine if it's working.
