For instance, a panic key that emits noises to frighten potential thieves in areas that are not accessible to them, such as underground garages.

Key fobs can do all this by sending an electronic signal between the car smart key and the key fob via low-power wireless technology. This is a fantastic option for drivers who are often in motion 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. Some of them even have an integrated touchscreen that allows drivers to control specific settings on their vehicle, like climate and audio.

The RFID signal that is transmitted between a key fob and car is unique, encoded and tied to the car's onboard computer. This makes it almost impossible for criminals with a technological background to hotwire a stolen car equipped with the key fob. These fobs can also be programmed to send the same frequency signal each time they're used. This means that the computer onboard won't recognize an old signal as the "true" signal.

Security

A lot of people are hesitant to use digital keys for their car due to the fact that they fear security. While having a physical key fob at hand does feel safer, it's important to realize that digital keys are 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 fob is damaged.

Unlike traditional key fobs, smart keys operate by utilizing built-in antennas inside your vehicle and the radio pulse generator inside the key fob to communicate with your vehicle, and perform standard functions such as unlocking and the start of it. This allows you to gain access to your vehicle without having the physical key to insert into the ignition or lock.

This makes it very difficult for thieves with the latest technology to gain access to a vehicle by using the frequency of a valid signal, reports How Stuff Works Electronics. smart key market keys transmit a unique encrypted signal each time the vehicle is locked or remotely opened.

Just like any battery-operated device the battery in a smart key will eventually deplete its juice. Most of the systems are designed with a backup method to unlock and start the Car smart key replacement in the event of a battery failure. The emergency method differs and usually involves holding the key within range of the car's lock sensor or pressing the key with a button that triggers the emergency starter.

Battery Backup

Although this system has a number of advantages, such as not having to search in the dark to find a key, it can be vulnerable to certain types of attacks. How Stuff Works Electronics reports that if the battery of your key gets depleted or lost, someone could pick up its low-frequency transmission signal and open your vehicle. This is why a majority of smart keys have encrypted signals to make hacking more difficult.

However, these systems may be affected due to electromagnetic fields generated by cell phones, computers and other devices. Therefore, if you notice that your smart key fob isn't working properly, it may be caused by interference. In this case you should not place your key near such devices until the battery of the device has been replaced. Fortunately, most smart keys will inform you well in advance when their batteries are low and the procedure to replace them is quite simple.
