The Toyota Highlander’s auto-lock function is designed as a safety precaution while traveling so that no doors are opened accidentally, and no one can get in from the outside. When the transmission is pulled from “Park” all the doors will automatically lock. When the transmission is pushed back into “Park” the doors will unlock in the same fashion. It is possible to turn off this auto-locking program in the vehicle’s computer.
Disable Auto Door Locks
Determine if the Toyota Highlander model uses a smart key system or not. If it does use a smart key system, all vehicle doors must be closed and the “Engine Start Stop” switch must be in the “Ignition ON” position. If there is no smart key system, then all the doors must be closed and the engine switch must be in the “ON” position.
Shift the transmission into “Park” or “Neutral” and use the driver’s side lock keys “one” or “two” for different functions.
