⚠️ 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 apply the parking brake firmly.
- Turn the ignition key to the ON position (position II) if the battery has any charge.
- Locate the shift lock override slot - it is a small rectangular slot on the left side of the shifter base, typically covered by a small plastic cap.
- Use a small flathead screwdriver or similar tool to pry off or remove the plastic cap covering the override slot.
- Insert a flathead screwdriver, ignition key, or similar flat tool into the override slot.
- Press down firmly on the override mechanism - you should feel resistance as you compress the shift lock spring.
- While holding the override down, press the brake pedal (if power available) and move the shifter from Park to Neutral.
- If no power is available, continue holding the override down and manually pull the shifter to Neutral - the mechanical override releases the lock cable.

With zero electrical power
The E30 M3 uses a purely mechanical shift lock system actuated by a cable connected to the brake pedal switch. With zero electrical power, the mechanical override slot works completely independently - simply press the override and shift to Neutral. No electrical power is required for the override to function. The steering column lock will remain engaged without power, but the transmission shifter operates mechanically.
