Key Fob Not Working in 2019 Toyota Camry

Step 1: Visual Inspection

  • Check for Physical Damage: Inspect the key fob for any visible damage such as cracks or water damage.
  • Inspect the Battery Compartment: Open the key fob to check for corrosion or debris.

Step 2: Battery Check

  • Tools Required:
    • Small Phillips screwdriver (to open the key fob)
    • CR2032 battery (replacement if needed)
  1. Open the Key Fob: Use the Phillips screwdriver to remove the screws and gently pry the fob apart.
  2. Remove the Old Battery: Take out the old battery and inspect it for any signs of leakage or corrosion.
  3. Test the Battery: Use a multimeter to check the voltage of the old battery (should be around 3 volts).
  4. Replace with New Battery: If the battery is low or dead, replace it with a new CR2032 battery, ensuring correct polarity.

Step 3: Reprogram the Key Fob (if necessary)

  • Tools Required:
    • Vehicle key fob (the one you are troubleshooting)
  1. Enter the Vehicle: Sit in the driver’s seat and close all doors.
  2. Turn the Ignition ON/OFF:
    • Insert the key fob into the ignition (if applicable) or press the push-to-start button twice without pressing the brake pedal.
    • Turn the ignition ON and OFF (do this 5 times in 10 seconds) until the car signals (locks/unlocks).
  3. Press the Lock Button: Once the vehicle is in programming mode, press and hold the lock button on the key fob for about 1 second.
  4. Finish Programming: Turn the ignition OFF to complete the programming process. Check if the key fob is working.
Tools Required for Further Diagnostics
  • OBD-II Scanner: To check for any related error codes in the vehicle's computer.
  • Multimeter: For checking battery voltage.
  • Screwdriver Set: For opening the key fob.
Repair Instructions

If Key Fob Still Doesn't Work

Step 1: Check for Vehicle-Side Issues

  1. Inspect the Receiver: The issue could be with the vehicle's keyless entry receiver.

    • Tools Required: OBD-II scanner.
    • Action: Scan for any DTCs (Diagnostic Trouble Codes) related to the keyless entry system.

  2. Check Vehicle Fuses:

    • Tools Required: Fuse puller or needle-nose pliers.
    • Action: Locate the fuse box (usually under the dashboard or in the engine compartment).
    • Inspect the fuses related to the keyless entry system and replace any blown fuses.
Step 2: Consult a Professional
  • If the key fob is still not functioning after replacing the battery and reprogramming, it may be necessary to consult with a dealership or a qualified automotive locksmith for further assistance.
