Is your 1997 Toyota Avalon Key Fob no longer working, or did you recently purchase a replacement and need to program it? Programming your key fob for your 1997 Toyota Avalon can be a straightforward process you can do yourself. This guide will walk you through the necessary steps to get your key fob working again, allowing you to remotely lock and unlock your doors with ease.
Step-by-Step Programming Guide for your 1997 Toyota Avalon Key Fob
Before you begin, ensure you have all your key fobs that you wish to program for your vehicle, as you will need to program them all at the same time. Here’s how to program your 1997 Toyota Avalon key fob:
-
Turn the Ignition Off: Make sure the key is completely out of the ignition. Programming cannot be initiated if the key is in the ignition switch.
-
Locate the Light Failure Sensor: The programming process involves accessing the Light Failure Sensor. This sensor is located in the trunk, near the left trunk hinge. You may need to pull back the trunk liner on the left side to expose it.
-
Disconnect the Sensor: Once you locate the Light Failure Sensor, disconnect it from the vehicle harness. It’s a plastic box with a white harness connector. Release the clip holding the sensor in place to remove it, and then detach the harness clip to separate the sensor box from the harness end. We will be using the harness end for programming.
-
Enter Programming Mode: Use a small jumper wire to connect terminal number 12 (PRG – Black wire) to terminal number 11 (GND – White/Black wire) on the 12-cavity Light Failure Sensor connector. Terminals 11 and 12 are the last two terminals on the lower complete row of the connector.

Confirm Programming Mode: Upon correctly grounding the circuit, your Toyota Avalon should confirm that it has entered programming mode. This is indicated by the power door locks cycling once (lock-unlock) and the trunk opener motor activating to unlock.
-
Program the Key Fob: Press and release any button on the key fob you wish to program. The vehicle will confirm successful registration of the remote by cycling the power door locks again (lock-unlock).
-
Program Additional Key Fobs (Optional): If you have another key fob to program, repeat steps 6 for each additional remote. Remember that a 1997 Toyota Avalon can have up to two remotes programmed to it.
-
Exit Programming Mode: Once you have programmed all desired key fobs, disconnect the jumper wire from terminals 11 and 12 of the Light Failure Sensor connector. This will exit the programming mode.
Now you should be able to use your programmed 1997 Toyota Avalon key fob to remotely lock and unlock your vehicle. If you encounter any difficulties during this process, or prefer professional assistance, consider searching for a local key fob programming service in your area.
