Convenience

Smart keys are designed to unlock doors and trunks and turn on the car engine and turn on the ignition without the driver having to utilize a traditional metal key. They also have features specifically designed to stop burglaries and vehicle thefts, such as panic buttons, which creates a loud sound to deter people who may be suspicious of thieves in remote areas like underground parking garages.

These key fobs do all this by sending a radio signal between the car and the key fob, using a low-power wireless technology. This is a fantastic feature, especially for drivers on the move who don't have a lot of time.

Smart keys are typically more like plastic cards than actual keys. They are used to unlock the trunk or doors when a button is pressed on the fob. Some smart keys feature a touchscreen that lets drivers to control their vehicle's settings, like the climate and audio.

The RFID signal sent between a key fob to a car is distinct, encrypted, and tied to the computer onboard this makes it virtually impossible for thieves with a technological background to hotwire a stolen vehicle equipped with one. These key fobs can be programmed to transmit an updated frequency signal each time they're used. This means that the onboard computer won't recognize an old signal 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 at hand does feel more secure, it's important to understand that digital keys are also more secure than you might think. The digital keys are encrypted and the signal they send to a car is verified by an onboard computer. The vehicle won't be able to start in the event that the smart key fob is stolen.

Unlike traditional key fobs smart keys make use of built-in antennas inside your vehicle and a radio pulse generator in the key fob to connect with your vehicle and perform basic functions like unlocking and opening it. This system lets you gain access to your vehicle without an actual key that you insert into the lock or ignition.

If you lose your smart car key coding keys, or if the battery fails, most systems offer an alternative method to open and start your car. For instance emergency starting could be done by putting the key into a slot or putting it near a particular area on the cockpit, where an inductive coil that can transfer energy is hidden.

Furthermore, many smart keys have a low battery indicator that will alert you before it goes completely dead. If you need to, you can easily replace the batteries on your own.

Auto-adjusting settings

Smart keys send a unique, encrypted signal every time the vehicle is unlocked or remotely opened.

The battery of a smart key will eventually wear out, just like any other battery-powered device. Most systems come with backup systems to unlock the car and then start it if the battery fails. The emergency method varies however, it is usually holding the key within range of the lock sensor or pressing a button on the key that triggers the emergency starter.

Battery backup

Modern smart keys, which are also known as keyless entry systems or passive entry use a transmitter and receiver to unlock your car.

For instance, if the key's battery goes out or is lost, someone else could pick up the low frequency transmission signals that are transmitted by your key and then open your car, according to How Stuff Works Electronics. This is why most smart keys have encrypted signals to make hacking more difficult.

However, these systems could also be impacted through electromagnetic fields created by computers, cell phones and other devices. So if you find that your smart car key programmer key fob isn't functioning properly, it could be caused by an interference issue. In this situation it is advised not to place your key near these devices until the battery of the device has been replaced.
