Key fobs can do all of this by transmitting an audio signal between the car and the key fob using the low-power wireless technology. This is a great convenience, especially for those who are frequently on the go and don't have much time to spare.

The RFID signal transmitted between the car and a key fob is unique, encoded and connected to the vehicle's onboard computer. This makes it nearly impossible for tech-savvy criminals to hotwire a stolen car equipped with a key fob. These key fobs can be programmed to transmit the same frequency signal each time they're used, meaning the computer that's onboard won't recognise an old one as the "true" signal.

Security

A lot of people are hesitant to switch to digital keys for cars for the reason that they are worried about security. While having a traditional key fob in your pocket may feel safer but digital keys are more secure than the majority of people think.

This is helpful if you need to limit certain features or have multiple drivers.

Smart keys also have the benefit of using encryption to protect against theft. This is not a possibility with traditional keys. This technology makes it difficult for tech-savvy thieves to gain access to a vehicle by using a valid frequency signal, reports How Stuff Works Electronics. Smart keys transmit a distinct encrypted message each time the remote is unlocked.

The battery of a smart key will eventually run out just like any other battery-powered device. The majority of systems are designed with a backup method to open the door and start the car when the battery is not working. The emergency method is different and usually involves holding the keys within the range of the car's lock sensor or pressing a button on the key that triggers the emergency start.

For example, if the key's battery fails or is stolen, a third party could detect the low frequency transmission signals from the key and gain access to your car, as per How Stuff Works Electronics. The majority of smart keys are encrypted signals, which makes hacking more difficult.

However, these systems can also be interfered with by electromagnetic fields produced by computers, cell phones and other devices. So if you find that your smart key fob isn't functioning correctly, it could be due to interference issues.
