- Get Inside and Close Doors: Enter your 2019 Toyota Corolla and ensure all doors are completely closed.

- Remove the Key: Take the key completely out of the ignition.
- Open and Close Driver’s Door (Twice): Within 40 seconds of removing the key, open and then close the driver’s side door two times.
- Insert and Remove Key Again: Insert the key into the ignition and quickly remove it one more time. Ensure this step is also completed within the 40-second timeframe.
- Door Locks Cycle: If you’ve successfully entered programming mode, you should hear the door locks cycle (lock and unlock) automatically. This indicates your 2019 Toyota Corolla is ready to learn the new key fob signal.
- Press Lock and Unlock Buttons: On the key fob you are programming, press and hold the “lock” and “unlock” buttons simultaneously for about 1.5 seconds. Then release.
- Press Lock Button (Again): Immediately after releasing the lock and unlock buttons, press and hold the “lock” button on the key fob for about 1.5 seconds and release.
- Locks Cycle Again (Confirmation): If the programming is successful for that key fob, you should hear the door locks cycle once more.
- Test Your Key Fob: Press the buttons on your newly programmed key fob to lock and unlock your 2019 Toyota Corolla to confirm it is working correctly.
- Programming Additional Fobs (If Needed): If you have additional key fobs to program, repeat steps 8-10 within 40 seconds.

If the programming is not successful on the first try, carefully repeat the steps, ensuring you are within the time limits specified.
Troubleshooting and Tips
Encountering issues during the 2019 Toyota Corolla key fob programming process is not uncommon. Here are some troubleshooting tips and advice:
