They also have features that are designed to help deter break-ins and theft of vehicles, such as a panic button that produces a sound to frighten away people who might be a threat to thieves or in remote areas like underground parking garages.

Key fobs can perform all of these functions via an audio signal between the car key fob and the car via low-power wireless technology. This is an excellent option for drivers who are often on the go and don't have much time to spare.

Smart keys are usually 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 of them even come with built-in touchscreens that allow users to control certain settings of their vehicle, like audio and climate.

The RFID signal sent between the key fob and the car is unique, encoded and connected to the car's onboard computer. This makes it almost impossible for criminals who are tech-savvy to hotwire a stolen car equipped with a key fob. The fobs can also be programmed to transmit a different frequency each time they're used to ensure that the computer doesn't recognize the old one as the true signal.

Security

Many people are hesitant to adopt digital keys as they are concerned about security. While having a physical key fob in your hand can feel more secure, it's important to know that digital keys are also more secure than you think. They're encrypted and the signal they transmit to a car is checked by a computer onboard. This means that even if your smart key fob is compromised the car will not start.

This is helpful if you want to restrict certain features or have multiple drivers.

Smart keys also have the advantage of encryption to stop theft. This isn't a possibility with traditional keys. This makes it difficult for thieves with the latest technology to take over a vehicle by using a valid frequency as reported by How Stuff Works Electronics. replacement smart car key keys send a unique encrypted signal each time the vehicle is locked or remotely opened.

Just like any battery-operated device the battery of a smart keys will eventually be depleted of power. The majority of systems have a backup system to open the car and start it if the battery is not able to function. The emergency method is different however, it is usually keeping the key within the range of the lock sensor or pressing an appropriate button on the key that triggers the emergency start.

The transmitter is incorporated into the key fob that is carried with you and the receivers are placed in your vehicle as well as around the outside of it. The receivers can detect the radio frequency signal transmitted by your smart key when you approach the vehicle, and they then open the ignition and doors.

The system has numerous advantages, such as not having to look in the dark for keys, however it is vulnerable to certain types of attacks. How Stuff Works Electronics reports that if your key's battery goes out or is damaged the person who has it could detect its low-frequency transmission signal, and open your vehicle. The majority of smart key car keys come with encrypted signals, which makes hacking more difficult.

If you notice that your smart key fob does not function properly, it could be due to a problem with interference. In this case you shouldn't place your key in proximity to such devices until the battery of the device has been replaced.
