What is a Smart Key Car Key?

Smart keys are also known as proximity keys or key fobs. They are used to unlock doors as well as start engines without having to insert physical key. They communicate with radiofrequency signals.

Apart from that, it helps to protect cars by preventing attempts at hotwiring. Smart keys transmit unique encrypted signals that prevent access to other vehicles.

Convenience

Instead of having to insert the key into an ignition slot to lock and unlock your vehicle by merely touching the handle on your door or trunk. Many modern cars also have a feature which allows you to start your car wirelessly. This is particularly useful when you're taking groceries home or transporting passengers and equipment.

This technology is designed to help protect against theft of vehicles. Instead of transmitting a single frequency signal, like a traditional key fob does it sends out several encrypted signals to a car's embedded antennas when you come close to it. How Stuff Works Electronics explains that this is a way to prevent other cars from receiving and responding the same signal.

Some manufacturers also use 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 can be beneficial should you lend your vehicle to family and friends.

This can help keep unexperienced drivers safe, and is particularly helpful if you have young children in the back of the vehicle.

Security

Traditionally, keys were cut from metal to open the ignition. With the advent of smart keys, it is no longer required. Smart keys are equipped with a specific 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, which means that only the owner of the car can use it. In addition, many models will shut off the engine if the vehicle was not started within the last few minutes. This feature is especially useful in case you're in a hazardous area or you have to leave the vehicle for any reason, for instance, at a gas pump.

Furthermore, if the smart car key programming key battery gets depleted during a journey, many systems offer a backup method of opening and starting the vehicle. The backup system involves inserting the key into a slot, or holding it close to an 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 if needed.

Battery Life

Most newer cars come with keyless entry systems and push-button starters. They are controlled by a smart key fob that communicates with the car via proximity technology. These systems are powered by a tiny transmitter that is powered by a lithium coin-sized battery. Like all batteries, it eventually needs replacement.

The majority of smart car spare key key fob batteries last for several years however that doesn't mean they'll never lose power and stop working abruptly. A dead fob means you can't unlock or start the car, even when you hold it near the door to the front and the key fob's light flashes.

A single lock/unlock signal takes only a fraction of the fob's battery and that's many years of signals' worth of battery life for the average smart key battery.

The fob will also drain the battery if placed in proximity to other devices that emit electromagnetic fields, such as computers and phones. These devices create their own magnetic field which could interfere with the fob's transmitter and cause it to run slower. RepairPal reports that the fob could be inoperable if placed too close to the gadgets.

Maintenance

In contrast to the traditional car key, a smart one uses technology to manage the locks on your vehicle and perform other functions. It functions by transmitting an indication from the fob to antennas located inside and outside the vehicle. The antennas pick up the signal and communicate with the computer in your car. The car responds to the signal and allows you to open and start it without using a physical key.

New cars are packed with advanced electronic features and the fob is now an interface for many of these functions. The most obvious uses are locking and unlocking your car, remote starting and chirping to help you locate your car in a parking space. Some fobs let you store specific settings for different drivers and remotely open windows and sunroofs.

The fob is an intricate electronic device that includes an integrated board. It can be damaged if it is placed in a position that is too harsh or exposed to extreme heat or cold. The transmitter can be broken if it is hit or dropped or smashed. The contacts on the battery can become bent.

The issues are often difficult to pinpoint and solve. You can use your phone to overcome this issue to determine if it's working.
