Fixing a Malfunctioning Key Fob for a 2022 Toyota Camry XV70

Tools Required
  • Flathead screwdriver (for opening the key fob)
  • CR2032 battery (replacement for the key fob)
  • Multimeter (for battery testing)
  • Owner’s manual (for reprogramming instructions)
Repair Instructions
Step 1: Open the Key Fob
  1. Use a flathead screwdriver to gently pry open the key fob. Start from the seam and work your way around to avoid damaging the casing.
  2. Carefully separate the two halves of the fob to access the battery.
Step 2: Replace the Battery
  1. Remove the old CR2032 battery from the compartment.
  2. Insert a new CR2032 battery, ensuring the positive side (+) is facing up.
  3. Snap the fob halves back together securely.
Step 3: Reprogram the Key Fob

  1. Enter Programming Mode:

    • Sit in the driver’s seat with all doors closed.
    • Insert the key into the ignition and turn it to the "On" position (do not start the engine).
    • Turn the ignition to "Off" and remove the key.
    • Repeat this process 5 times, ending with the ignition in the "On" position on the last attempt. The doors should lock and unlock, indicating that the vehicle is in programming mode.

  2. Program the Key Fob:

    • Press and hold the "Lock" button on the key fob for 5 seconds.
    • Release the button and then press it again. The doors should lock and unlock again, confirming successful programming.
    • Repeat this step for any additional key fobs.

  3. Exit Programming Mode:

    • Turn the ignition to "Off" to exit programming mode. Test the fob to ensure it locks/unlocks and starts the engine.
Step 4: Test Key Fob Functionality
  1. Stand at a distance of about 5-10 feet from the vehicle and press the lock/unlock buttons to ensure they function correctly.
  2. Attempt to start the vehicle using the push-to-start button with the key fob inside the car.
Final Considerations
  • If the key fob still does not function after replacing the battery and reprogramming, it may need to be replaced or further diagnostics may be necessary to check the vehicle's receiver.
  • If you are unsure or uncomfortable performing these steps, consult a certified Toyota technician for assistance.
