Step-by-Step Programming Instructions for Your 2005 Toyota Avalon Key Fob
Follow these instructions carefully to program your 2005 Toyota Avalon key fob. Ensure you perform each step accurately and within the specified timeframes for successful programming.
-
Preparation: Begin with your 2005 Toyota Avalon completely off. Remove the key from the ignition. Ensure that the driver’s side door is unlocked and open, and all other doors are closed tightly. This initial setup is crucial for initiating the programming sequence.
-
Initiate Programming Sequence (Part 1): Within 5 seconds of completing step 1, insert your key into the ignition cylinder, but do not turn it. Immediately remove the key. Repeat this insert and remove key cycle one more time within the same 5-second window. This quick key insertion and removal is the first signal to your Avalon that you intend to enter programming mode.
-
Initiate Programming Sequence (Part 2): Within 40 seconds of completing step 2, you need to operate the driver’s side door lock mechanism twice. Close, then open the driver’s side door. Repeat this close and open door cycle once more. Following the door operation, insert the key into the ignition cylinder again, without turning it, and remove it immediately.
-
Enter Programming Mode: Within 40 seconds of step 3, perform the door lock operation sequence again: Close, then open the driver’s door twice. After this, insert the key into the ignition and leave it in the cylinder. Close the driver’s door. Now, turn the ignition key to the “ON” position, then immediately turn it back to the “OFF” position. Do not start the engine. Finally, remove the key from the ignition.
-
Confirmation of Programming Mode: If you have successfully followed the previous steps, within 3 seconds of removing the key in step 4, the power door locks should automatically cycle – locking and then unlocking. This automatic lock cycle is your confirmation that your 2005 Toyota Avalon has successfully entered key fob programming mode.
-
Key Fob Programming: Within 40 seconds of the door locks cycling, take your key fob remote. Press and hold both the “lock” and “unlock” buttons simultaneously for approximately 1.5 seconds. After releasing both buttons, immediately press and hold down only the “lock” button. Keep the “lock” button pressed for about 10 seconds. During this time, the door locks should cycle again – lock and then unlock once – indicating successful programming of your key fob.
-
Final Step: Open the driver’s side door to conclude the programming sequence. Test your newly programmed 2005 Toyota Avalon key fob to ensure all buttons are functioning correctly – lock, unlock, and panic (if applicable).
If you encounter any difficulties during this 2005 Toyota Avalon Key Fob Programming process, double-check each step and timing. If issues persist, it may be necessary to consult a professional automotive locksmith or Toyota dealership for further assistance.
