Step-by-Step GX470 Key Fob Programming Instructions
-
Get Inside and Lock Up: Begin by entering your Lexus GX470, ensuring all doors are completely closed and securely locked.
-
Master Key Insertion: Insert your already registered master key into the ignition switch. This action will turn off the blinking security indicator light located on your dashboard.
-
Key Removal: Take the registered master key out of the ignition.
-
Open Driver’s Door: Unlock and open the driver’s side door. Keep the driver’s door open throughout the next steps.
-
Key Cycling (Twice): Within 5 seconds of opening the door, insert and remove the registered master key into the ignition switch two times in quick succession.
-
Door Cycle (Twice): Within 40 seconds of the previous step, perform a door cycle by closing and then opening the driver’s door two times.
-
Key Cycling (Once): Insert and remove the registered master key from the ignition switch one more time.
-
Door Cycle (Twice Again): Within 40 seconds, repeat the door cycle: close and open the driver’s door two times again.
-
Key Insertion and Door Closure: Insert the registered master key into the ignition switch and then close the driver’s door.
-
Ignition Cycle (Once): Switch the ignition to the ON position and then immediately back to the OFF position, doing this only one time. This step initiates the key remote transmitter code programming while ensuring your original key codes are retained.
-
Key Removal and Confirmation: Remove the registered master key from the ignition switch. At this point, the system should automatically lock and unlock the vehicle doors one time. This single lock/unlock cycle indicates successful entry into programming mode. If you see a lock/unlock cycle twice, it indicates failure, and you’ll need to return to step 1 and repeat the process.
-
Button Press Synchronization (Hold): Within 40 seconds, take the new key fob you are programming and press and hold down both the LOCK and UNLOCK buttons simultaneously for approximately 1.5 seconds.
-
Button Press Confirmation (Release): Within 3 seconds after releasing the LOCK and UNLOCK buttons, press and release either the LOCK or the UNLOCK button one time. Again, observe the vehicle’s response: one lock/unlock cycle confirms successful registration of the new gx470 key fob. Two lock/unlock cycles mean registration failed, and you should retry from step 12.
-
Programming Additional Remotes: If you have more key fobs to program, repeat the button procedure starting from step 12 for each additional remote within 40 seconds.
-
Exiting Programming Mode: To exit the key fob programming mode, you can either open the driver’s door or insert the ignition key. Remember, a maximum of 4 key remote transmitters can be programmed to your Lexus GX470.
By following these steps, you can easily program your gx470 key fob and maintain control over your vehicle’s access system. Always test each programmed key to ensure it functions correctly after programming is complete.
