How do I change the lock handing? If you have already setup the lock with the Yale Access App, to re-hand the lock see I have handed my lock incorrectly. How do I change the handing? To hand the lock, hold down on the metal slide tab on the inside of the handle located towards the bottom. Rotate the handle downwards to the left or right, depending on your selected handing. Ensure you complete this step for both handles. If you feel any resistance when handing do not force the handle. Release the tab and handle try again. This is shown in step 3 of the Yale Unity Instruction Guide.
