Luckily, programming your key fob for your 2004 Toyota Tundra is a straightforward process you can accomplish right at home.

Before you begin, ensure you have all your key fobs you wish to program for your 2004 Toyota Tundra, as you’ll need to program them all in one session. Follow these instructions carefully to successfully program your 2004 Toyota Tundra key fob:
-
Start Procedure: Begin with your 2004 Toyota Tundra completely off, the key removed from the ignition, the driver’s side door open, and all other doors closed and locked. Ensure the driver’s door is unlocked.
-
Key Insertion Sequence (5 seconds): Within 5 seconds, perform the following key insertion and removal sequence rapidly:
A. Insert the key into the ignition (do not turn it).
B. Remove the key from the ignition.
C. Insert the key into the ignition again (do not turn it).
D. Remove the key from the ignition again. -
Door and Key Sequence (40 seconds): Within 40 seconds of the previous step, execute this sequence:
A. Close the driver’s side door, then open it.
B. Close the driver’s side door again, then open it.
C. Insert the key into the ignition (do not turn it).
D. Remove the key from the ignition. -
Final Door and Ignition Sequence (40 seconds): Within 40 seconds, complete these actions:
A. Close the driver’s side door, then open it.
B. Close the driver’s side door again, then open it.
C. Insert the key into the ignition and leave it in the ignition cylinder.
D. Close the driver’s door.
E. Turn the ignition to the “ON” position (without starting the engine), then immediately turn it back to the “OFF” position.
F. Remove the key from the ignition. -
Confirmation of Programming Mode: Within 3 seconds of removing the key, the power door locks should automatically cycle (lock then unlock). This automatic lock and unlock cycle indicates that your 2004 Toyota Tundra has successfully entered programming mode. If the locks do not cycle, return to step 1 and repeat the process.
-
Key Fob Programming (40 seconds): Now, program each key fob remote within 40 seconds:
A. Press and hold both the “lock” and “unlock” buttons on the key fob simultaneously for approximately 1.5 seconds.
B. Immediately after releasing both buttons, press and hold only the “lock” button for 2 seconds.
C. Within 3 seconds, the door locks should cycle once (lock then unlock) to confirm successful programming of that remote. If the door locks cycle twice, it indicates the remote was not accepted. In this case, repeat steps 6A and 6B for that specific remote.
D. Repeat steps 6A and 6B for each additional 2004 Toyota Tundra key fob you need to program. -
Exit Programming Mode: Open the driver’s side door. This action will exit the programming mode.
