Understanding Key Fob Programming

Before diving into the specifics, let’s understand the fundamental concept of key fob programming.

• Standard Key Fobs: These fobs feature basic functions like unlocking, locking, and trunk release. They usually have a single button for each function.
• Smart Key Fobs: Often referred to as “push-button start” fobs, these offer advanced features like keyless entry, remote start, and panic mode. They usually have multiple buttons and a key blade.
