Method 1: Standard Programming Procedure
This method is a common approach for programming Toyota key fobs and may work for your 2005 Tundra. Follow these steps carefully:
-
Preparation: Ensure the driver’s door is unlocked and open, and all other doors are closed. Remove the key from the ignition.
-
Key Insertion Sequence (Twice): Within 5 seconds, insert the key into the ignition (do not turn it) and immediately pull it out. Repeat this insert and remove key action once more.
-
Door Cycling Sequence (Twice): Within 40 seconds, close and then open the driver’s door. Repeat this close and open door action once more.
-
Key and Door Sequence: Within 40 seconds, insert the key into the ignition (do not turn it) and pull it out.
-
Door Cycling Sequence (Twice – Again): Within 40 seconds, close and then open the driver’s door. Repeat this close and open door action once more.
-
Final Key and Door Steps: Insert the key into the ignition and leave it there. Close the driver’s door. Turn the ignition to the “ON” position, then immediately back to the “OFF” position (do not start the engine). Remove the key from the ignition.
-
Confirmation of Programming Mode: Within 3 seconds, the power door locks should automatically cycle (lock then unlock). This indicates that your 2005 Toyota Tundra has successfully entered programming mode. If the door locks do not cycle, return to step 1 and repeat the procedure or try the alternate method.
-
Remote Programming: Within 40 seconds of the door locks cycling:
- A. Press and hold both the “lock” and “unlock” buttons on the key fob simultaneously for 1.5 seconds.
- B. Immediately after releasing both buttons, press and hold the “lock” button by itself.
- Within 10 seconds, the door locks should lock and then unlock once 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 A and B in step 8.
-
Programming Additional Remotes: Repeat step 8 (A and B) for each additional key fob you need to program.
-
Exit Programming Mode: Open the driver’s door. This action should conclude the programming sequence.
-
Testing: Test all programmed key fobs to ensure they correctly lock and unlock your 2005 Toyota Tundra.
Method 2: Alternate Programming Procedure
If the standard procedure does not work, this alternate method may be effective for your 2005 Toyota Tundra Key Fob Replacement.
-
Preparation: Ensure all doors are closed. Open only the driver’s door.
-
Key and Door Lock Switch Sequence:
- Insert the key into the ignition, then remove it.
- Press the “LOCK” and “UNLOCK” buttons on the vehicle’s door lock switch (located on the door panel) alternately at 1-second intervals, repeating this sequence 5 times.
-
Door Cycling Sequence (Again):
- Close and then re-open the driver’s door.
- Press the “LOCK” and “UNLOCK” buttons on the vehicle’s door lock switch again at 1-second intervals, repeating this sequence 5 times.
-
Ignition Sequence: Insert the key into the ignition switch. Turn the ignition to the “ON” position, then immediately back to the “OFF” position (do not start the engine).
-
Key Removal: Remove the key from the ignition.
-
Confirmation of Programming Mode: The door locks should cycle automatically, confirming entry into programming mode.
-
Remote Programming:
- Press and hold both the “LOCK” and “UNLOCK” buttons on the key fob together for 1.5 seconds.
- Then, immediately press and hold the “LOCK” button until the door locks cycle once to confirm programming. If the locks cycle twice, the programming has failed, and you should repeat this step.
