They also come with features designed to deter vehicle burglaries and thefts, such as a panic key that emits noises to deter criminals 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 by using the low-power wireless technology. This is a fantastic feature, particularly for drivers on the go who don't have a lot of time.

The RFID signal sent between a key fob and a car is distinct, encrypted, and tied to the computer onboard, making it almost impossible for tech-savvy thieves to hotwire a stolen vehicle equipped with one. The fobs can also be programmed to transmit a different frequency signal each time they're used to ensure that the computer can't recognize the previous one as the authentic signal.

Security

Many people are reluctant to adopt digital keys because they are concerned about security.

Smart keys transmit a distinct encrypted message each time the vehicle's remote or unlocked.

The battery of a smart key will eventually wear out as does any other battery-operated device. Most of the systems are designed with a backup method to unlock and start the car in the event of a battery failure. The emergency procedure can differ, but it usually involves holding the key within the proximity to the sensor for the lock on the car or pressing a button which activates the emergency starter.

For instance, if your key's battery is damaged or is lost, someone else could pick up the low-frequency transmission signals of your key and unlock your car, according to How Stuff Works Electronics. The majority of Smart forfour key replacement keys are encrypted signals, making hacking more difficult.

If you find that the smart key fob isn't able to function properly, it could be due to an issue with interference. In this instance, you should not put your key near a device until the battery of the fob has been replaced.
