Convenience

smart fortwo key replacement keys are designed to open trunks and doors, turn on the car engine, and then turn off the ignition without needing to use a traditional key made of metal. They also come with features that are designed to prevent vehicle burglaries and thefts, including the panic key that makes noises to deter potential thieves in remote areas like garages underground.

Key fobs fulfill all of these functions via an audio signal between the car key fob and the car, using low-power wireless technology. This is a great option for those on the move who don't have a lot of time.

Smart keys generally look more like plastic cards than actual keys. They can be used to open the trunk or doors when a button is pressed on the fob. Some smart forfour key keys have a touchscreen that allows motorists to control their vehicle's settings, such as climate and audio.

The RFID signal sent between a key fob and the vehicle is distinct, encrypted, and tied to the computer in the car this makes it virtually impossible for hackers with the latest technology to connect a stolen car equipped with one. Key fobs can also be programmed to send a new frequency signal each when they're utilized, so the onboard computer won't recognize an old one as the "true" signal.

Security

Many people aren't keen to adopt digital car keys because they worry about security. While having a physical fob in hand can feel safer the digital keys are more secure than most people think. They're encrypted, and the signal that they send to a vehicle can be verified by a computer onboard. The car won't start when the smart key fob is compromised.

This technology makes it extremely difficult for thieves who are tech-savvy to gain access to a vehicle by using an acceptable frequency signal according to How Stuff Works Electronics. smart key replacement keys send a distinct encrypted signal each time the vehicle is locked or remotely opened.

The battery of a smart car key programming key will eventually run out like any other battery-powered device. Most systems are built with a backup system to open the door and start the car when the battery is not working.
