How to Program a 2007 Mercury Mariner Ignition Chip Key Transponder

Step by Step How to Programming Instructions:

### Programming with Two Recognized Transmitters:
1. **Prepare Recognized Transmitters:**
– Place the two recognized transmitters in the rear cupholder in the center console.

2. **Access Driver Door Handle:**
– Remove the key lock cylinder cap on the driver door handle.

3. **Initiate Programming Mode:**
– Insert the vehicle key of the new transmitter into the key lock cylinder on the driver door handle.
– Turn the key to the unlock position five times within 10 seconds.
– The Driver Information Center (DIC) will display “READY FOR REMOTE #2, 3, 4, or 5, 6, 7, or 8”.

4. **Replace Transmitter:**
– Replace one of the recognized transmitters with the new transmitter.
– Place the new transmitter in the rear cupholder in the center console.

5. **Program Transmitter:**
– Press ENGINE START/STOP.
– Once the transmitter is learned, the DIC will indicate readiness to program the next transmitter.

6. **Repeat for Additional Transmitters:**
– Remove the transmitter from the transmitter pocket and press Lock or Unlock.
– Repeat steps 3 through 5 for each additional transmitter.
– When all additional transmitters are programmed, press and hold ENGINE START/STOP for twelve seconds to exit programming mode.

### Programming without Currently Recognized Transmitters:
1. **Access Driver Door Handle:**
– Remove the key lock cylinder cap on the driver door handle.

2. **Initiate Programming Mode:**
– Insert the vehicle key of the transmitter into the key lock cylinder on the driver door handle.
– Turn the key to the unlock position five times within 10 seconds.
– The DIC will display “REMOTE LEARN PENDING, PLEASE WAIT”.

3. **Wait for Prompt:**

8. **Exit Programming Mode:**
– When all additional transmitters are programmed, press and hold ENGINE START/STOP for twelve seconds to exit programming mode.

These steps should guide you through the process of programming transmitters for your vehicle, depending on whether you have two recognized transmitters or none currently recognized.
