For instance, the panic key that makes sounds to frighten away potential thieves in areas that are not accessible to them, such as underground garages. These key fobs do all of these functions by sending an audio signal between the car and the key fob by using the low-power wireless technology. This is an excellent feature, particularly for drivers on the move and don't have a lot of time. A smart key is usually shaped more like a plastic card rather than a key, and can be used to open the trunk or car's doors when a button on the fob is pressed. Some even come with an integrated touchscreen that allows drivers to control specific settings on their vehicle, including the climate and the audio. The RFID signal that is transmitted between the key fob and the car is unique, encoded and tied to the car's onboard computer. This makes it almost impossible for hackers with the right skills to wire a stolen vehicle equipped with a key fob. The fobs can also be programmed to transmit a new frequency signal each time they're used, so the computer in the car won't be able to recognize an old signal as the “true” signal. Security Many people are hesitant to adopt digital keys as they are concerned about security. While having a tangible key fob to hand does feel safer, it's important to know that digital keys are also more secure than you think. Digital keys are secure and the signal they transmit to a car is analyzed by an onboard computer. The vehicle won't start if the smart key fob is damaged.

This isn't a possibility with traditional keys. This technology makes it difficult for thieves with the latest technology to steal a vehicle by imitating an authentic frequency signal, reports How Stuff Works Electronics. Smart keys send a distinct encrypted signal each time the vehicle is left unlocked or remotely opened. The battery of a smart key will eventually wear out as does any other battery-operated device. Most of the systems are designed with a backup method to open the car and start it in the event of a battery failure. The emergency method differs in the majority of cases, but it involves keeping the key within the range of the lock sensor or pressing the key with a button that activates the emergency starter. Battery Backup Modern smart keys are recognized by the names of keyless entry systems as well as passive entry. They make use of a transmitter to unlock your vehicle.

For example, if the key's battery fails or is lost, another person could be able to pick up 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, making hacking more difficult. If you notice that the smart key fob does not work properly, this could be due to an issue with interference. In this instance you should avoid placing your key in proximity to any device until the battery on the key has been replaced.
