Smart keys can unlock doors, trunks and turn on the engine of the vehicle without the need to use a metal key. They also have features designed to help deter break-ins and vehicle thefts, such as panic buttons, which produces a sound to frighten away potential thieves or suspicious people in areas with no security like underground garages for parking.

These key fobs do all this by sending an electronic signal between the car and the key fob, using a low-power wireless technology. This is a wonderful convenience, particularly for drivers who are frequently traveling and don't have a lot of time to spare.

Smart keys generally look more like plastic cards than actual keys. They can be used to open the trunk or doors when you press a button on the fob. Certain smart keys come with an electronic touchscreen that allows drivers to control the vehicle's settings, like audio and climate.

The RFID signal that is sent between the key fob to a car is unique, secure and connected to the computer in the car this makes it virtually impossible for hackers with the latest technology to wire a stolen vehicle equipped with one. These fobs can also be programmed to send a new frequency signal every time they're used, so the computer onboard won't recognize an old one as the "true" signal.

Security

A lot of people are hesitant to adopt digital keys because they are worried about security. While having a physical key fob at hand does feel more secure, it's important to understand that digital keys are more secure than you think. The digital keys are encrypted and the signal they send to a vehicle is checked by an onboard computer. The car won't start if the smart fob is damaged.

This technology makes it difficult for thieves with the latest technology to take over a vehicle by using a valid frequency that is reported by How Stuff Works Electronics. Smart keys send a distinct encrypted signal each when the vehicle is unlocked or remotely opened.

The battery of a smart key will eventually run out just like any other battery-powered device. Most of the systems are equipped with a backup plan to open the car and start it if the battery fails. The emergency procedure varies, but usually involves either keeping the key within the range of the car's lock sensor or pressing the button on the key that activates the emergency starter.
