Step 2: Enter Your Vehicle
This might seem obvious, but ensure you are inside your car for the key fob programming procedure. Being inside the vehicle is essential for optimal signal transmission between the key fob and your car’s onboard computer system.
Step 3: Insert the Key into the Ignition
Insert your car key into the ignition. Turn the key to the ‘On’ position. This is the position right before you would start the engine. Do not start the engine yet. Turning the ignition to the ‘On’ position activates your vehicle’s electrical system and prepares it for the key fob programming sequence.

Step 4: Turn the Key to the ‘On’ Position (If Not Already Done)
If you have just inserted the key, you’re likely already in the ‘On’ position. If not, make sure the key is turned to the position just before the engine starts. This step is vital as it puts your car into programming mode, allowing it to recognize the signals from your key fob for reprogramming.
Step 5: Press the Lock Button on Your Key Fob
Locate the lock button on your key fob. Press and hold the lock button firmly for approximately five seconds. This action sends a signal to your vehicle’s electronic control unit (ECU), signaling that you are initiating the key fob programming sequence.
Step 6: Turn the Key to the ‘Off’ Position
After holding the lock button, turn the ignition key back to the ‘Off’ position. For some vehicles, this step, along with the previous one, might need to be repeated multiple times. Refer to your vehicle owner’s manual to find the exact number of cycles required for your specific car model. The number of cycles can vary between manufacturers and models.
Step 7: Repeat the Process as Needed
Repeat Steps 4 to 6 if necessary, strictly following the programming instructions outlined in your vehicle’s owner’s manual. Each vehicle manufacturer may have a different set of cycles or a specific sequence required to successfully program a key fob. Paying close attention to your manual is crucial at this stage.
Step 8: Test Your Reprogrammed Key Fob
Once you have completed the required programming cycles, it’s time to test if your key fob has been successfully reprogrammed. Remove the key from the ignition and test all the functions of your key fob. Try:
- Locking and Unlocking Doors: Press the lock and unlock buttons to ensure they are working correctly.
- Remote Start (If Applicable): If your key fob has a remote start feature, test if it starts the car engine.
- Panic Button: Test the panic button to ensure it also functions.
If all functions operate as expected, congratulations! You have successfully reprogrammed your key fob. If it doesn’t work on the first attempt, carefully repeat the previous steps, ensuring you follow each instruction precisely. If issues persist, consult your owner’s manual for troubleshooting tips or consider seeking professional assistance.
