This is similar to the way a tablet or smartphone that has a fingerprint scanner embedded functions.

A smart car key supplier key can also make cars safer by not sending the exact frequency signal repeatedly. If a fob sent a signal each time it unlocked or opened an trunk remotely, this could allow thieves to hotwire cars and remove them. Smart keys emit a unique signal every time a trunk or door is opened remotely.

Smart keys also stop vehicles from being taken by thieves at fueling stations and other parking lots. This is because they transmit a low-frequency signal that can be detected by an adjacent smart key however, not by any other person or objects that are not within the vehicle. The signal is only recognized within 10 cm of the smart key, so it is not possible for someone to steal your car by picking up a transmission from a nearby fob.

The key fob comes with an encrypted chip that the antenna inside your car can recognize. When you are within reach of your vehicle it will open the doors and start the engine.

Certain smart keys also store settings for the steering wheel, mirrors and the seat. You can set them by pressing a single button. This feature is becoming more popular and a rising number of manufacturers are introducing it to their vehicles.

The idea is to make it unnecessary to press a key fob when driving, so drivers can concentrate on driving safely and secure. The technology is already available in a few luxury cars and is growing in popularity with major automakers who are trying to meet customer demand.

This feature is helpful however, it could be risky if a driver fails to remove the key fob from their pockets prior to entering or leaving the vehicle. This is because smart key fobs emit an ultra-low-frequency signal that could be detected by a different device that could open the doors, or even pop the trunk. This is known as relay, and it's been used by cyber-savvy criminals to steal cars at fuel stations and parking spaces.

The majority of smart key systems include a backup mechanism for opening and starting the vehicle in the case of the battery being dead.

This means that a criminal with a technologically advanced mind could infiltrate the system and take your vehicle. Smart car keys generate an encrypted code that is different each time they carry out the task. This makes them difficult to crack and more difficult to be exploited by thieves with a technological edge.

Certain vehicles also allow you to start your car by walking towards it and pressing the button. These systems, unlike conventional models that require you insert and turn the keys they are powered by key fob batteries. The key fob transmits a signal to the car's radio to signal it that you're close, and the vehicle can then activate its power doors and start the engine.
