For instance, the panic key which makes noises to deter potential thieves in remote areas such as garages that are underground.

Key fobs can do all this by sending an audio signal between the car and the key fob, using low-power wireless technology. This is an excellent feature, especially for drivers on the move and do not have much time.

A smart key for smart car is usually designed to look more like an plastic card than a key, and can be used to open the trunk or car smart key replacement's doors when a button on the fob is pushed.

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

Security

A lot of people are hesitant to use digital keys for their car due to the fact that they worry about security. While having a traditional key fob at hand might feel more secure the digital keys are more secure than many believe.

Smart keys send a distinct encrypted signal each time the vehicle is locked or remotely opened.

The battery of a smart car replacement key key will eventually run out, just like any other battery-operated device. Most systems come with backup systems to unlock the car and begin it in the event that the battery fails. The emergency method differs however, it is usually holding the key within the range of the lock sensor or pressing a button on the key that triggers the emergency starter.

Battery Backup

Modern smart keys are also known by the names keyless entry systems or passive entry. They use an electronic transmitter to unlock your vehicle.

While this system comes with many advantages, such as not having to search in the dark for the key, it can be vulnerable to certain kinds of attacks. How Stuff Works Electronics reports that if a key's battery dies or is lost, someone could pick up the low-frequency transmission signal and gain access to your vehicle. This is why a majority of smart keys have encrypted signals to make hacking a challenge.

However, these systems could also be impacted through electromagnetic fields created by cell phones, computers and other devices.
