- Remote Start: Starts the engine remotely, allowing the vehicle to warm up or cool down before you enter.
1.2. The Importance of Key Fob Programming
Key fob programming is crucial for several reasons. It ensures that only authorized keys can operate your vehicle, preventing theft. Programming also allows you to customize the key fob’s functions, such as setting which doors unlock with a single press of the unlock button. Moreover, if you lose a key fob or purchase a replacement, programming is essential to pair the new fob with your vehicle’s system. According to the National Insurance Crime Bureau (NICB), vehicle theft is a significant concern, and proper key fob management is a vital part of vehicle security.
