⚠️ 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 vehicle is on a level surface and chocked if possible
- Turn the ignition key to the ACC or ON position (if battery has sufficient charge)
- Press and hold the brake pedal firmly
- Move the column shifter from Park through the gate to Neutral
- If the shifter will not move due to failed shift interlock or insufficient power, locate the shift lock override
- The shift lock override is typically a small slot or button near the base of the column shifter housing, often covered by a small trim piece or cap
- Use a small flathead screwdriver or the key to depress the override mechanism while gently pulling the shifter toward you to release it from Park
- Once in Neutral, the vehicle can be rolled; ensure the parking brake is released
Shift-lock override location
Near the base of the column shifter housing, typically on the right side or under a small trim cap; exact location requires visual inspection of the column shroud area
With zero electrical power
With zero electrical power, the shift lock may engage mechanically. Use the shift lock override (small slot near the column shifter base) with a screwdriver to manually release the shifter from Park. The override is purely mechanical and does not require battery power. You may need to remove or pry up a small trim piece near the shifter to access it.
