They also come with features that are designed to prevent burglaries and theft of vehicles, such as the panic button, which generates noise to scare away people who may be suspicious of thieves in areas that are isolated like underground garages with parking.

Key fobs accomplish all these things by sending an audio signal between the car and the key fob via a low-power wireless technology. This is a wonderful convenience, especially for drivers who are constantly in a hurry and don't have a lot of time to spare.

Smart keys are generally more like plastic cards than actual keys. They are used to unlock the trunk or doors when they are pressed by the fob. Some smart keys feature touchscreens that allow users to control their vehicle's setting, including the climate and audio.

The RFID signal that is sent between the key fob and the vehicle is unique, encrypted and linked to the computer onboard this makes it virtually impossible for tech-savvy thieves to wire a stolen vehicle equipped with one. These fobs are also programmable to send a different frequency signal every time they're used, to ensure that the computer can't recognize the previous one as the genuine signal.

Security

A lot of people are hesitant to adopt digital keys as they are concerned about security. While having a tangible key fob at hand does make you feel more secure, it's crucial to realize that digital keys are more secure than you think. They're secure, and the signal that they transmit to a vehicle is verified by a computer onboard. The vehicle won't start when the smart key fob is compromised.

Contrary to traditional key fobs smart keys make use of built-in antennas in your car and the radio pulse generator inside the key fob to communicate with your vehicle, and perform standard functions like unlocking and starting it. This technology allows you to gain access to your vehicle without having a physical key inserted into the lock or ignition.

Smart keys also have the benefit of encryption, which can prevent theft. This is not a possibility with traditional keys. This technology makes it extremely difficult for tech-savvy thieves to steal a vehicle by mimicking an acceptable frequency signal according to How Stuff Works Electronics. Smart keys transmit a distinct encrypted message each time the vehicle's remote or unlocked.

Just like any other battery-powered device the battery in a smart key will eventually run out of juice. Most systems come with a backup system to open the car's doors and start it if the battery is not able to function. The emergency method varies and usually involves holding the key within range of the lock sensor or pressing an appropriate button on the key that activates the emergency starter.

Battery backup

Modern smart Key replacement cost keys, often referred to as keyless entry systems or passive entry, utilize a transmitter and a receiver to unlock your car.

How Stuff Works Electronics reports that if a key's battery goes out or is damaged it is possible for someone to pick up its low-frequency transmission signal and then open your vehicle. This is the reason why many smart key repair keys come with encrypted signals that make hacking more difficult.

However, these systems may be affected through electromagnetic fields created by cell phones, computers and other devices. Therefore, if you notice that your smart fortwo key fob key fob is not functioning as it should, it could be caused by interference. In this instance it is best not to place your key near any device until the fob's battery has been replaced.
