Security

Many people are hesitant adopt digital keys because they are worried about security. While having a tangible key fob to hand does make you feel more secure, it's crucial to know that digital keys are also more secure than you might think.

Most systems are built with a backup system to open the door and start the car in the event that the battery fails. The emergency method is different, but it usually involves holding the key within the proximity to the lock sensor on the car or pressing a key button that activates the emergency start.
