2014 Toyota Tundra Key Fob Programming

Quick reference

Step-by-step on-board programming

Good news! The 2014 Toyota Tundra supports a DIY on-board programming procedure for adding new key fobs. Make sure you have at least one working master key and the new, unprogrammed remote.

Before you start:

• Gather all key fobs (working and new ones) you want to program. Any fobs not programmed during this procedure will be erased from the vehicle's memory.
• Ensure your battery is in good condition.
• Have all doors closed and unlocked.

Programming steps:

1. Start with the driver's door open and all other doors closed. Insert your working master key into the ignition. Do NOT turn the key yet.
2. Insert and remove the master key from the ignition switch two times within 5 seconds.
3. Close and open the driver's door two times within 40 seconds.
4. Insert and remove the master key from the ignition switch one time within 40 seconds.
5. Close and open the driver's door two times within 40 seconds.
6. Insert the master key into the ignition and leave it there.
7. Close the driver's door.
8. Turn the ignition switch from OFF to ON and back to OFF at least once (or twice, depending on whether you want to add a remote or rewrite all remotes). Pay attention to the power door locks; they should cycle to confirm you're in programming mode. The number of cycles indicates the mode:
   • One cycle: Add mode (adds to existing fobs).
   • Two cycles: Rewrite mode (erases all existing fobs and programs new ones).
   • Three cycles: Confirmation mode (checks how many fobs are programmed).
   • Five cycles: Prohibition mode (disables programming).
9. Remove the master key from the ignition. The door locks should cycle again, indicating the successful entry into programming mode.
10. On the new key fob, simultaneously press and hold the LOCK and UNLOCK buttons for 1 to 1.5 seconds.
11. Within 3 seconds, press the LOCK button only for 1 second and then release. The door locks should cycle once to confirm successful programming. If they cycle twice, the programming failed, and you'll need to repeat steps 10 and 11 or restart the entire process.
12. If you have additional fobs to program, repeat steps 10 and 11 for each additional fob within 40 seconds.
13. To exit programming mode, open the driver's door. Test all programmed fobs to ensure they work correctly.

Battery replacement

Replacing the battery in your 2014 Toyota Tundra key fob is a straightforward process:

1. Locate the seam: Most Tundra fobs have a small indentation or seam along the side.
2. Pry open the case: Use a small, flat-head screwdriver or a coin to carefully pry open the two halves of the fob case at the seam.
3. Remove the old battery: Note the orientation (positive/negative) of the old CR2032 battery before gently prying it out.
4. Insert the new battery: Place the new CR2032 battery in the correct orientation.
5. Snap the case back together: Align the two halves of the fob and press them firmly until they snap back into place.
6. Test the fob: Verify that the buttons are working correctly.
