To make use of this feature, a person must place their finger on a sensor located close to the door knob or lock handle (depending on vehicle configuration). This is similar to how a phone or tablet equipped with an embedded fingerprint scanner works.

A smart key can also ensure the safety of vehicles by not sending the exact frequency signal repeatedly. If a key sent the same signal every time it unlocked a door, or remotely opened the trunk, it could allow thieves who are tech-savvy to connect vehicles to hot wires and make them disappear. Smart keys emit a different signal each time a trunk or door is opened remotely.

Smart keys also help prevent cars from being taken away by thieves at fuel stations and other parking lots. This is because they send the signal at a low frequency that can be picked up by an adjacent smart key near me key but not by other people or objects that are not within the vehicle.

The key fob contains an encrypted chip which the antenna inside your vehicle detects. When you are within range of your car, it knows to unlock the doors and/or start the engine.

Some smart keys can also save settings for the seats mirrors, the steering wheel and seat that allow you to alter them with a single click. This feature is becoming increasingly popular and a rising number of manufacturers are adding it to their vehicles.

The automotive smart car key reprogramming key industry is growing due to the growing demand for safety features. These features minimize wear and tear on the ignition system of a vehicle and ensure that the driver is the sole person who is able to stop or start the engine.

Smart key fobs emit low-frequency signals which could be picked up by other devices that open doors or pop the boot. It's a tactic referred to as a relay attack and has been used by thieves with a technological advantage to steal cars from drivers at fueling stations, as well as in parking lots.

However, many smart key systems come with an alternate method of opening and starting the vehicle when the battery is dead. The driver typically has to place the dead key fob in a slot or put it near a designated area of the cockpit to trigger an emergency starting system, which typically involves an inductive coil which transfers energy from the key to the car.

However, because the key for smart car fob sends out these signals, it's possible for a criminal to intercept these signals and control the vehicle.

Open Road Auto Group explains that traditional key fobs emit the same frequency signal each time they unlock the door or remotely pop the trunk. This implies that a hacker could possibly gain access to the system to steal your vehicle. Smart car keys emit a different encrypted code every time they perform the task. This makes them much harder to crack, and even more difficult for thieves who know how much is a replacement smart car key to exploit.

Certain vehicles allow you to start your car fob replacement by walking towards it and pressing the button. These systems, unlike traditional models that require you insert and turn the keys, are powered by key fob batteries.
