Garage Doors decision guide
Reviewed and updated September 24, 2026
A manual slide lock is intended to restrain the door; the opener should not be used to pull against it. Stop pressing the control. If the lock is loaded by the door or will not release freely, leave it alone. DASMA’s damage-inspection guidance specifically treats a slide lock under tension as a reason to stop rather than force the lock open.
Leave a loaded or stuck slide lock untouched, prevent further opener commands, and give a trained technician the door position and event sequence.
A manual slide lock is meant to restrain the door, so the opener should not pull against it. Stop pressing the wall control, remote, or app as soon as you recognize that the lock is engaged. Repeated operation can turn a simple control mistake into a condition that needs inspection; this page does not diagnose whether damage occurred.
If the lock is under load from the door or does not release freely, leave it alone. Do not pull harder, use the opener to unload it, or reach into tensioned door hardware. DASMA's damage-inspection guidance treats a slide lock under tension as a stop condition rather than an invitation to force it open.
Record the door position, whether the opener was activated, and any visible change that can be seen without touching components. Keep others from operating the controls. Ask a trained door-system technician to evaluate the exact lock, door, and opener if the lock remains loaded, the door changed position, or operation no longer appears normal.
