They also have features that are designed to deter burglaries and vehicle theft, like a panic button, which makes noise to scare away people who might be a threat to thieves or in isolated areas, such as underground garages for parking.

The key fobs perform all of this by transmitting radio signals between the car and the key fob by using a low-power wireless technology. This is a great feature for drivers on the move and don't have a lot of time.

A smart key is usually designed to look more like an plastic card than an actual key, and it can be used to open the trunk or doors of a car when the fob's button is pressed.

The RFID signal transmitted between the key fob Duplication Cost fob and the car is distinct, encrypted, and tied to the computer in the car this makes it virtually impossible for thieves with a technological background to connect a stolen car equipped with one. The fobs can also be programmed to send an updated frequency signal each time they're used, so the computer onboard won't recognize an old one as the "true" signal.

Security

Many people are hesitant to use digital keys for their car for the reason that they worry about security. Although having a physical key fob on hand may feel safer the digital keys are more secure than people believe. Digital keys are encrypted and the signal they transmit to a car is verified by an onboard computer. This means that even if the smart key fob is stolen, the car will never start.

Unlike traditional key fobs, smart keys make use of built-in antennas inside your vehicle and a radio pulse generator in the key fob that allows it to communicate with your vehicle, and perform standard functions like unlocking and opening it. This feature lets you access your vehicle without the need to insert an actual key into the lock or ignition, which is often an issue.

This is beneficial if you have multiple drivers or want to restrict certain features when lending your car to a new driver.

Another benefit of smart keys is the fact that they use encryption to prevent theft, which isn't possible with traditional keys. This technology makes it difficult for thieves who are tech-savvy to steal a vehicle by imitating an acceptable frequency signal according to How Stuff Works Electronics. Smart keys send a distinct encrypted signal each time the vehicle is left unlocked or remotely opened.

The battery of a smart key will eventually wear out as does any other battery-powered device. The majority of systems have an emergency mechanism to open the car and begin it if the battery is not able to function. The emergency method can vary, but it usually involves holding the key in range of the sensor for the lock on the car or pressing a button which activates the emergency starter.
