I replace the battery the key box, and It still doesn't work. Its a factory alarm in my car. Can I get a replacement for this, Due to the year of the car. 1996 Toyota Avalon.
The key fob probably needs to be programmed to the car again. The below procedure should work for 2003-2008 Avalons.
Procedure To Program Toyota Wireless Remote Transmitters:
Begin with: The driver's door open and unlocked. Key out of the ignition.
- Insert and remove the key from the ignition switch 2 times within 5 seconds.
NOTE: Steps 2 and 3 should be performed within 40 seconds.
- Close and open driver's door TWICE.
- Insert the key in the ignition and remove it.
NOTE: Steps 4 - 6 should be performed within 40 seconds.
- Close and open the driver's door twice.
- Insert the key in the ignition.
- Close the door.
Turn the ignition switch from "Lock" to "On" and back to "Lock" 1 time.
Remove the key from the ignition.
To confirm you are in program mode, the power locks will now cycle "lock" to "unlock" 1 time.
NOTE: If Confirmation or Prohibition modes have been selected, opening the door will complete the procedure.
- To Add a remote, do the following within 40 seconds
Procedure Lock confirmation:
A. Press both car transmitter Lock and Unlock buttons simultaneously between 1 and 1.5 seconds and release.
B. Within 3 seconds of step A, press the transmitter Lock button for more than 1 second and release.
If the keyless entry remote transmitter has been successfully programmed, the power locks will cycle "lock" to "unlock" once at this time.
If there are problems with the remote transmitter or the procedure up to this point, the locks will cycle twice. If this occurs, verify that you have received the correct transmitter, and then repeat the above procedure.
C. If multiple remotes are to be reprogrammed, repeat steps A and B.
- Open the driver's door to conclude programming mode.
