⚠️ 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 access - look for a small plastic cap or slot in the steering column shroud below and slightly ahead of the shifter lever base
- Remove the plastic cover by prying gently with a small flat-blade screwdriver
- Insert a small flat-blade screwdriver, ignition key, or similar narrow tool into the override slot
- Push the override mechanism firmly while simultaneously pressing the shifter button and moving the lever toward Neutral
- The transmission should release from Park and allow movement to Neutral
Shift-lock override location
Small slot or hole in the steering column shroud below the shifter lever, typically covered by a removable plastic cap
With zero electrical power
With zero electrical power, the mechanical shift lock override will still function - no battery power is required to actuate the override mechanism. However, the steering column lock will remain engaged without power, preventing steering wheel rotation, which may complicate loading onto a flatbed.
