Programming your 2012 Toyota Yaris key fob can seem daunting, but it’s actually a straightforward process you can accomplish at home. This guide provides two simple methods to program your key fob, allowing you to regain remote access to your vehicle quickly and efficiently. Whether you’ve lost a key fob, added a new one, or are simply troubleshooting, follow these instructions to get your 2012 Toyota Yaris key fob working perfectly again.
Method 1: Standard Key Fob Programming Procedure
This method is the primary way to program your 2012 Toyota Yaris key fob. Ensure you have all the key fobs you wish to program with you before starting.
-
Prepare the Vehicle: With all doors closed, unlock and open only the driver’s side door. Make sure all other doors remain closed throughout this process.
-
Key Insertion Sequence (Within 5 Seconds):
- Insert your key into the ignition switch (do not turn it) and immediately pull it out.
- Repeat this insert and remove key action once more within 5 seconds.
-
Door Cycling Sequence (Within 40 Seconds):
- Close and then open the driver’s door.
- Repeat the close and open driver’s door action once more.
- Insert the key into the ignition switch (do not turn it) and pull it out.
-
Final Door and Ignition Sequence (Within 40 Seconds):
- Close and then open the driver’s door again.
- Repeat the close and open driver’s door action one last time.
- Insert the key into the ignition and leave it in the ignition switch.
- Close the driver’s door.
- Turn the ignition to the “ON” position, then immediately turn it back to the “OFF” position. Do not start the engine.
- Remove the key from the ignition.
-
Confirmation of Programming Mode (Within 3 Seconds): At this point, the power door locks should automatically cycle (lock then unlock). This automatic lock and unlock sequence indicates that your 2012 Toyota Yaris has successfully entered programming mode. If the door locks do not cycle, return to step 1 and carefully repeat the procedure. You can also try the alternate procedure detailed below.
-
Remote Programming (Within 40 Seconds):
- Step A: On the key fob you are programming, press and hold both the “lock” and “unlock” buttons simultaneously for approximately 1.5 seconds.
- Step B: Immediately after releasing the “lock” and “unlock” buttons, press and hold only the “lock” button by itself. Within 10 seconds, the door locks should cycle once (lock then unlock) to confirm successful programming of that key fob. If the door locks cycle twice, it indicates the remote was not accepted. In this case, repeat steps A and B for the same remote.
- Repeat steps A and B for each additional key fob you need to program.
-
Exit Programming Mode: Open the driver’s door to exit the programming mode.
-
Test Your Key Fobs: Thoroughly test each programmed key fob to ensure they properly lock and unlock the doors of your 2012 Toyota Yaris.

Method 2: Alternate Key Fob Programming Procedure
If the standard method does not work for your 2012 Toyota Yaris, you can try this alternate programming procedure. Ensure you have all remotes you wish to program ready before you begin. Note that while these instructions are generally for Toyota vehicles, step 10a is specifically for Toyota Avalon models, while step 10b is for all other Toyota vehicles, including the Yaris.
-
Vehicle Preparation: Ensure all doors are fully closed before starting.
-
Open Driver’s Door: Open only the driver’s side door.
-
Key Insertion: Insert your key into the ignition switch, and then immediately remove it.
-
Door Lock Switch Cycle (5 Times): Press the “LOCK” and “UNLOCK” buttons on the vehicle’s door lock switch alternately at approximately 1-second intervals, repeating this cycle a total of 5 times.
-
Close and Re-open Driver’s Door: Close the driver’s door and then re-open it.
-
Door Lock Switch Cycle Again (5 Times): Repeat the action from step 4. Press the “LOCK” and “UNLOCK” buttons on the vehicle’s door lock switch alternately at 1-second intervals, 5 times.
-
Key Insertion into Ignition: Insert the key into the ignition switch.
-
Ignition Cycle: Turn the ignition to the “ON” position, and then immediately back to the “OFF” position. Do not start the engine.
-
Key Removal: Remove the key from the ignition switch.
-
Confirmation of Programming Mode: The door locks should cycle automatically to confirm that the vehicle has entered programming mode.
- a. For Avalon: If you were programming a Toyota Avalon (not applicable to Yaris), you would press the “LOCK” button on the remote for a minimum of 1 second at this point.
- b. For All Other Vehicles (Including Yaris): For your 2012 Toyota Yaris, press and hold both the “LOCK” and “UNLOCK” buttons on the key fob together for 1.5 seconds. Then, immediately press and hold only the “LOCK” button until the door locks cycle.
-
Programming Confirmation: The door locks should cycle once to confirm successful programming of the key fob. If the locks cycle twice, the programming has failed.
-
Program Remaining Remotes: Repeat the button procedure from step 10b to program any remaining key fobs.
-
Final Step and Testing: Close the driver’s door. Test all programmed remotes to ensure they are functioning correctly with your 2012 Toyota Yaris.
