⚠️ Chock the wheels first — neutral means the car can roll. Set the parking brake while you work, never stand downhill of the vehicle, and try a 12-volt jump before any override: power fixes most stuck-in-park problems instantly.
The procedure
- Ensure the parking brake is firmly set and wheels are chocked
- Turn the ignition key to the ACC or ON position if battery has any charge remaining
- Locate the shift lock override slot - it is a small rectangular opening in the column shroud directly below and slightly forward of the shifter lever
- Remove the small plastic cover from the override slot by prying gently with a flat-blade screwdriver
- Insert a flat-blade screwdriver or similar tool into the override slot and push firmly downward/inward
- While holding the override tool depressed, press the shifter button and move the lever to Neutral
- The shifter should release and move freely while the override is engaged

With zero electrical power
With zero electrical power, the mechanical shift lock override will still function. You do not need battery power to use the override slot. However, you will not be able to turn the steering wheel without key power due to the steering column lock, which may complicate loading onto a flatbed.
