⚠️ 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
- Set the parking brake firmly and chock the wheels
- Turn the ignition key to ON position (or ACC if battery is weak but not completely dead)
- Locate the shift lock override: look for a small covered slot on the left side of the shifter base assembly, typically covered by a small plastic cap or trim piece
- Remove the protective cap carefully using a flathead screwdriver or trim tool
- Insert a small flathead screwdriver or key into the override slot and push down firmly
- While holding the override depressed, press the shifter release button on top of the shifter knob and move the lever forward into the Neutral gate position
- The J-gate design allows lateral movement; ensure you're moving into the main gate before pulling forward to Neutral

With zero electrical power
With completely dead battery, the mechanical override still functions. You must hold the override tool depressed with significant pressure while manipulating the shifter button and lever. The J-gate may feel stiff without power assistance. If the parking pawl is under load, rock the vehicle gently to relieve pressure. Two people make this easier—one holding the override, one moving the shifter.
