These key fobs can be programmed to send a new frequency signal each time they're used, meaning the computer that's onboard won't recognise an old signal as the "true" signal.

Security

Many people are hesitant to adopt digital keys because they are worried about security. While having a physical fob in hand can feel more secure but digital keys are more secure than many think.
