Ignition Insertion (Twice): Within a tight 5-second window, insert your key into the ignition switch and immediately pull it out. Repeat this insert and pull out action a second time.
-
Driver’s Door Cycle (Twice – Close/Open): Next, perform a door cycle. Close, then open the driver’s side door twice in succession.
-
Ignition Insert and Remove: Insert the key into the ignition switch one more time, and then remove it.

Driver’s Door Cycle (Twice Again – Close/Open): Repeat the driver’s side door cycle. Close, then open the driver’s side door two more times.
