Navigate to Key Fob Programming:
- Turn on the ignition.
- Follow the tool’s on-screen prompts to navigate to the key fob programming section. This might be under “Immobilizer,” “Key Programming,” or a similar category.
Follow On-Screen Instructions:

8. Understanding Mazda’s Advanced Keyless Entry System

Newer Mazda CX-9 models often come with an advanced keyless entry system. This system adds convenience but also complexity to key fob programming.

Features of the Advanced Keyless Entry System

Push-Button Start: Start your car without inserting a key.
Keyless Entry: Unlock the doors by simply touching the door handle.
Remote Start: Start the engine remotely (if equipped).

How the System Works

The advanced keyless entry system uses radio frequency identification (RFID) to communicate between the key fob and the vehicle. When you approach the car, the system detects the key fob and allows you to unlock the doors or start the engine with the push of a button.

9. Reprogramming After Battery Replacement

Sometimes, after replacing the battery, the key fob may need to be reprogrammed. Follow these steps:

Manual Synchronization:
- Insert the key into the ignition and turn it to the “ON” position.
- Wait for a few seconds, then turn it back to “OFF.”
- Remove the key and try using the key fob.
Diagnostic Tool Method:
- If manual synchronization doesn’t work, use a diagnostic tool to reprogram the key fob following the steps outlined earlier.
