They also have features designed to deter vehicle burglaries and thefts, such as a panic key that emits noises to scare off potential thieves in areas that are not accessible to them, such as garages that are underground.

Key fobs accomplish all this by sending radio signals between the car and the key fob using low-power wireless technology. This is a fantastic convenience, particularly for drivers who are always in motion and don't have much 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 the button is pressed on the fob. Some of them even have built-in touchscreens that allow users to control certain settings on their vehicle, like audio and climate.

The RFID signal sent between a key fob and car is unique, encoded and connected to the vehicle's onboard computer. This makes it impossible for hackers with the right skills to hotwire a stolen car equipped with the key fob. They can also be programmed to transmit a different frequency signal every time they're used, so that the computer isn't able to recognize the old one as the real signal.

Security

Many people are hesitant to use digital keys for their car because they are concerned about security. While having a tangible key fob in your hand can feel more secure, it's important to know that digital keys are also more secure than you think.

This is useful if you have multiple drivers or need to limit certain features when you loan your car to a novice driver.

Smart keys also have the advantage of using encryption to protect against theft. This is not a possibility with traditional keys. This technology makes it extremely difficult for thieves who are tech-savvy to steal a vehicle by using an acceptable frequency signal reports How Stuff Works Electronics. Smart keys transmit a unique encrypted message each time the remote is unlocked.

The battery of a smart key will eventually run out like any other battery-powered device. The majority of systems have an emergency mechanism to open the car and start it in case the battery fails. The emergency procedure can differ however, it is usually keeping the key within the proximity to the lock sensor on the car or pressing a key button that triggers the emergency starter.

Battery Backup

Modern smart key for cars keys are recognized by the names of keyless entry systems or passive entry. They utilize a transmitter to unlock your vehicle. The transmitter is situated inside the key fob that you carry around and the receivers are located in and around your vehicle.

The system has numerous advantages, like not having to look in the dark for keys, but it is vulnerable to certain types attacks. For instance, if the key's battery is damaged or is lost, someone could be able to pick up the low-frequency transmission signals from your key and open your car, as per How Stuff Works Electronics. The majority of smart keys are encrypted signals, making hacking more difficult.

However, these systems may be affected by electromagnetic fields produced by cell phones, computers and other devices. So if you find that your smart key fob is not functioning correctly, it could be due to interference issues. In this instance you should avoid placing your key in proximity to any device until the battery of the fob has been replaced.
