They also come with features designed to help deter break-ins and vehicle theft, like a panic button, which produces a sound to frighten away people who may be suspicious of thieves in areas that are isolated like underground parking garages.

Key fobs accomplish all this by sending radio signals between the car and the key fob, using a low-power wireless technology. This is an excellent feature, particularly for drivers on the go who do not have much time.

Smart keys are generally more like plastic cards than actual keys. They can be used to unlock the trunk or doors when you press a button on the fob. Some of them even have an integrated touchscreen that allows drivers to control certain settings on their vehicle, like the climate and the audio.

The RFID signal sent between the key fob and a car is unique, secure and connected to the computer onboard which makes it nearly impossible for hackers with the latest technology to wire a stolen vehicle equipped with one. The fobs can also be programmed to transmit an updated frequency signal each time they're used, meaning the computer onboard won't recognize an old one as the "true" signal.

Security

Many people aren't keen to make the switch to digital car keys because they are worried about security. While having a tangible key fob on hand may make you feel more secure, it's crucial to recognize that digital keys are also more secure than you think.
