They also come with features designed to deter vehicle burglaries and thefts. For instance, the panic key that makes noises to scare off potential thieves in isolated areas such as underground garages. Key fobs can perform all of these functions by sending a radio transmission between the car key fob and the car via low-power wireless technology. This is a wonderful feature for drivers on the move who don't have a lot of time. Smart keys are generally more like plastic cards than actual keys. They are used to unlock the trunk or doors when the button is pressed on the fob. Some even have an integrated touchscreen that allows users to control certain settings of their vehicle, like the climate and the audio. The RFID signal transmitted between the key fob and the car is unique, encrypted and linked to the computer onboard which makes it nearly impossible for tech-savvy thieves to wire a stolen vehicle equipped with one. They can also be programmed to transmit a different frequency signal every time they're used, so that the computer can't recognize the previous one as the authentic signal. Security Many people are hesitant to adopt digital keys because they are worried about security. While having a physical key fob in your pocket may feel more secure the digital keys are more secure than many think.

This technology makes it very difficult for tech-savvy criminals to take over a vehicle by using a valid frequency according to How Stuff Works Electronics. smart car key replacement cost send a unique, encrypted signal every time the vehicle is left unlocked or remotely opened. As with any other device powered by batteries the battery in a smart key will eventually be depleted of power. Most systems come with a backup system to open the car's doors and start it if the battery fails. The emergency method differs in the majority of cases, but it involves keeping the key within the range of the car's lock sensor or pressing the key with a button which activates the emergency starter. Battery backup Modern smart keys, often referred to as keyless entry systems or passive entry, utilize a transmitter and a receiver to unlock your vehicle. The transmitter is situated inside the key fob that you carry around, and the receivers are located both inside and outside your car.
