Why is my lock handle is turning up?
Please follow the steps below re-installing the lock to solve the issue.
Step 1. Take the front panel, and ensure the "lock shaft tightener" is vertically aligned with ground,
not to the left, not to the right.
Step 2: Ensure the “Shaft Hole” on the latch is squarely straight to the ground, not at 45 degrees.
Step 3: Insert lock shaft into the shaft hole and re-install lock. During installation, please ensure that all screws are tightened appropriately.
