They also come with features designed to deter vehicle burglaries and thefts, including a panic key that emits noises to deter criminals in remote areas like garages underground.

These key fobs perform all of these functions by sending a radio transmission between the car key fob and the car via low-power wireless technology. This is a fantastic feature for drivers on the move who don't have a lot of time.

Security

Many people are reluctant to adopt digital keys as they are concerned about security. While having a tangible key fob on hand may make you feel more secure, it's crucial to recognize that digital keys are more secure than you think.

Smart keys transmit a unique encrypted signal each time the vehicle is unlocked or remotely opened.

Just like any battery-operated device, a smart key's battery will eventually run out of juice. The majority of systems have an emergency mechanism to open the car and then start it if the battery fails.
