Is your 2004 Toyota Avalon Key Fob no longer working, or did you get a replacement that needs programming? Don’t worry, programming your key fob for your 2004 Toyota Avalon can be a straightforward process you can do yourself. This guide will walk you through the steps to get your key fob working again so you can regain the convenience of remote locking and unlocking.
Before you begin, ensure you have all your key fobs that you want to program for your 2004 Toyota Avalon, as you’ll need to program them all in one session. Follow these instructions carefully to successfully program your key fob:
-
Starting Position: Begin with your key removed from the ignition. Make sure the driver’s side door is open and unlocked. Crucially, ensure all other doors and the trunk are completely closed. This starting configuration is essential for initiating the programming sequence.
-
Key Insertion Sequence: Within 5 seconds of starting in the correct position, insert your key into the ignition and then immediately pull it out. Repeat this insert and pull out action a second time. This quick key cycling is a signal to the car to prepare for programming.
-
Door Cycling – Part 1: Next, you need to cycle the driver’s side door. Close the driver’s side door and then open it again. Repeat this close and open door cycle a second time. This door operation is part of the vehicle’s recognition sequence for key fob programming.
-
Key Insertion – Second Time: Insert the key into the ignition one more time, and then remove it again. This is another step in confirming to the vehicle that you are initiating the programming mode.
-
Door Cycling – Part 2: Repeat the door cycling process. Close the driver’s side door and then open it again, followed by a second close and open cycle. This second door cycle set further confirms the programming initiation.
-
Final Key Insertion for Programming: Now, insert the key into the ignition and this time, leave it in the ignition. Do not remove it.
-
Close Driver’s Door: Close the driver’s side door. Keep the key in the ignition and the door closed for the next step.
-
Ignition Cycling: With the key still in the ignition and the driver’s door closed, switch the ignition to the ON position, and then immediately switch it back to the OFF position.
-
Remove Key and Confirmation: Remove the key from the ignition. At this point, if you have correctly followed the steps, the door locks should cycle automatically. This lock cycling is the vehicle’s way of confirming that it has successfully entered key fob programming mode.
-
Programming the Fob: Take the first key fob you wish to program. Press and hold both the LOCK and UNLOCK buttons simultaneously for about 1.5 seconds. After releasing these buttons, immediately press and hold only the LOCK button for 2 seconds.
-
Confirmation of Remote Programming: After holding the LOCK button, the door locks should cycle once more. This cycle confirms that the remote you just programmed has been successfully recognized by your 2004 Toyota Avalon. If you have additional key fobs to program, repeat step 12 for each additional remote.
-
Complete Programming: To finalize the programming process, simply open the driver’s side door. Programming is now complete for your 2004 Toyota Avalon key fob.
