5. Understanding Transponder Keys and PATS

The 1998 Ford Explorer utilizes a transponder key system, also known as Passive Anti-Theft System (PATS). Understanding this system is crucial for key programming.

5.1. What is a Transponder Key?

A transponder key has a microchip embedded in the plastic head. This chip transmits a unique electronic code to the vehicle’s immobilizer system. If the code matches, the engine is allowed to start.

5.2. How PATS Works

When the key is inserted into the ignition, the vehicle sends a radio frequency signal to the transponder chip. The chip responds with its unique code. If the code is valid, the immobilizer disarms, and the engine can start.

5.3. Implications for Programming

Key Cutting is Not Enough: Simply cutting a new key to match the ignition lock cylinder is not sufficient. The transponder chip must also be programmed to match the vehicle’s immobilizer system.
Programming is Required: Programming involves using a diagnostic tool or specific on-board procedures to teach the vehicle the new key’s transponder code.
Limited Programming Attempts: Some vehicles limit the number of keys that can be programmed.

6. Key Fob Replacement Options

If your key fob is lost or damaged beyond repair, you’ll need to consider replacement options:

6.1. Aftermarket Key Fobs
