🧰 Drafted with AI under the editorial review of Chris Hackleman & Jeff Moore — details like the exact override location may vary by trim; verify visually before prying anything.
⚠️ 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 the vehicle is on level ground or properly chocked
- Turn the ignition key to position 1 (accessories) or position 2 if battery has any remaining charge
- Locate the shift lock override slot - it is a small rectangular opening covered by a plastic cap on the left side of the shifter base (driver's side)
- Use a flathead screwdriver or the metal key blade to pry off the plastic cap
- Insert the screwdriver or key blade into the override slot and press down firmly
- While holding the override down, press the shifter button and move the shifter to neutral
- If the ignition cannot be turned due to steering lock, you may need to wiggle the steering wheel while turning the key

With zero electrical power
With completely dead battery, the steering lock will engage and the key cannot be turned. You must jump-start the 12V battery minimally to release the steering lock before accessing neutral. The shift lock override is mechanical and will work once ignition is in position 1, but steering lock requires some electrical power. If jump-starting is impossible, the vehicle must be winched onto a flatbed with wheels free.
