How do you turn key back in 86 Buick Regal?

To turn the key back in an '86 Buick Regal, simply insert the key into the ignition and turn it to the "Off" position. If the key is stuck, ensure the gear shift is in the "Park" position; if it's not, the ignition may be locked. Gently wiggle the steering wheel while turning the key can also help release any tension. If you're still having trouble, check for any issues with the ignition lock cylinder or key itself.
