⚠️ 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 the ON position (do not start)
- Press and hold the brake pedal firmly
- Press the shift lock release button on the shift lever and move to Neutral
- If the brake pedal does not release the shifter, locate the shift lock override - it is accessed by removing the small rectangular cover at the base of the shift lever where it enters the column
- Insert a small screwdriver or similar tool into the override slot and press down while simultaneously pulling the shift lever toward you to move it to Neutral
Shift-lock override location
At the base of the shift lever where it enters the steering column, behind a small rectangular cover that pries off; the override slot is visible once the cover is removed
With zero electrical power
With completely dead battery and no jump source: Remove the shift lock override cover at the column base. The override mechanism on this generation can be activated mechanically without power. Insert tool into the slot and apply firm pressure while manipulating the shift lever. If unsuccessful, you may need to access the shift cable at the transmission end under the truck - disconnect the cable from the transmission lever and manually move the transmission lever forward two detents to Neutral.
