The key fobs perform all of this by transmitting an audio signal between the car and the key fob by using low-power wireless technology. This is a fantastic option for those who are on the move and do not have much time.

A smart key is typically shaped more like a plastic card than a key, and can be used to open the trunk or doors of a car when a button on the fob is pressed. Some smart keys have a touchscreen that lets motorists to control their vehicle's setting, including audio and climate.

The RFID signal transmitted between the key fob and the car is unique, encoded and linked to the car's onboard computer. This makes it almost impossible for hackers with the right skills to connect a stolen vehicle equipped with the key fob. These fobs are also programmable to send a different frequency signal every time they're used, so that the onboard computer isn't able to recognize the old one as the genuine signal.

Security

A lot of people are hesitant to make the switch to digital car keys due to the fact that they are concerned about security. While having a tangible key fob on hand may feel more secure, it's important to realize that digital keys are more secure than you might think. They're encrypted, and the signal that they send to a vehicle can be verified by a computer onboard. This means that even if the smart key fob is compromised the car won't start.

In contrast to traditional key fobs smart keys operate by utilizing built-in antennas in your vehicle and the radio pulse generator inside the key fob. This allows it to communicate with your vehicle, and perform standard functions like unlocking or starting it.

Smart keys also have the benefit of using encryption to prevent theft. This is not a possibility with traditional keys. This technology makes it very difficult for cybercriminals to gain access to a vehicle by mimicking a valid frequency, reports How Stuff Works Electronics. Smart keys transmit a distinct encrypted message each time the vehicle's remote or unlocked.

Just like any battery-operated device, a smart car key fob replacement key's battery will eventually be depleted of power. Most systems come with backup systems to unlock the car and then start it in the event that the battery fails.
