Being inside the vehicle is necessary to ensure proper signal transmission during the car key fob programming procedure.
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. Turning the key to the ‘On’ position activates your vehicle’s electrical system and prepares it to enter programming mode.
Inserting the car key into the ignition and turning it to the ‘On’ position activates the car’s electrical system for key fob programming.
Step 4: Press the Lock Button on Your Key Fob
Locate the lock button on your key fob. Firmly press and hold the lock button for approximately five seconds. This action sends a signal to your vehicle’s electronic control unit (ECU), indicating that you are initiating the key fob programming sequence.
Pressing and holding the lock button on the car key fob initiates the programming sequence with the vehicle’s ECU.
Step 5: Turn the Key to the ‘Off’ Position (and Repeat if Necessary)
After holding the lock button, turn the key back to the ‘Off’ position in the ignition. You may need to repeat turning the key from ‘On’ to ‘Off’ multiple times. The exact number of cycles required varies depending on your specific vehicle make and model. Refer to your owner’s manual for the precise number of cycles needed for your car. This cycling process helps the car recognize the programming signal from the key fob.
Turning the ignition key to the ‘Off’ position, potentially repeated multiple times, is a step in the car key fob programming process.
Step 6: Test Your Key Fob
Once you have completed the required cycles of turning the key and pressing the lock button, it’s time to test if the key fob has been successfully programmed. Remove the key from the ignition. Try the buttons on your key fob. Test locking and unlocking your car doors using the fob. If your key fob includes a remote start function, test that as well.
If the key fob functions correctly, congratulations! You have successfully reprogrammed your car key fob. If it doesn’t work on the first try, carefully repeat the previous steps, ensuring you follow each step precisely. If you are still having trouble, consult your vehicle’s owner manual for specific troubleshooting tips or consider seeking professional assistance.
