1. Ensure the ignition key is inserted into the ignition slot and turned to the "On" position. This provides power to the electrical system and allows you to engage the override mechanism or use the key.
2. Locate the Shift Interlock Release Override Slot. It's typically a small hole or slot near the gear shift lever. Refer to your vehicle's owner's manual for the exact location.
3. Insert a suitable tool into the Shift Interlock Release Override Slot. This can be a flat-head screwdriver, Allen key, or the key provided with your vehicle for this purpose.
4. Press and hold down the Shift Interlock Release Override while simultaneously moving the gear shift lever out of the "Park" position. Continue to hold down the override until the gear shift lever is in the desired gear.
5. Test the gear shift by moving it between different positions to ensure it's functioning correctly and not stuck again.
If you're unable to release the gear shift using the override slot, there may be an underlying issue with the shift interlock system or transmission. In this case, it's recommended to take your vehicle to a qualified mechanic or auto repair shop for diagnosis and repair.
