1. Understanding the 2015 Ford Mustang Key Fob System
The 2015 Ford Mustang uses an intelligent access key system, designed to enhance security and convenience. This system relies on coded keys programmed specifically to your vehicle.

1.2. Security Features
The key fob system incorporates several security features to protect your vehicle from theft:
- Rolling Codes: Each time you use the key fob, it transmits a different code, preventing replay attacks.
