On the old wooden door out back, one lock bar hangs loose from a rusted guide and the other is bent at an angle, so the handle turns but the door can still be lifted a hand's width from outside.
When an automatic opener is on the door, the manual lock and the motor have to be kept from meeting. Opener makers ask for the lock to be disabled or removed when the machine is installed, and the door industry's own guidance says the same, because a motor pulling against an engaged bar bends the bar, loosens the lock and strains the opener. Lock repair on a powered door therefore includes a decision: keep the lock removed or disabled and rely on the opener's own lock-out feature, or fit a manufacturer-approved interlock if the household wants the lock available when the power is off.

Scene 1
The outside handle is turned while the inside of the door is watched. On a healthy lock the spindle rotates the centre body, a cam pushes both bars outward and a spring pulls them back. When the handle turns but nothing follows, the fault is somewhere in that short chain: a spindle that has twisted or sheared, a set screw that has let the inside knob spin free, a cam that has worn round, or a spring that has snapped. The inside cover comes off to see which, and the body is checked for cracks or for pulling away from the door. The exact broken piece decides whether a small part or a complete mechanism is fitted.
Scene 2
When the outside handle is cracked, corroded through or of a pattern that no longer has parts, a complete T-handle set is fitted: exterior handle with cylinder, spindle, inside turn handle and the mounting hardware. The technician measures door thickness to choose spindle length and bolt length, and checks that the new handle's mounting holes match the existing cutout or dresses the opening to suit. On insulated doors a sleeve keeps the spindle centred through the foam. The set is tightened evenly so the handle turns without rubbing the door face, the cylinder is tested with its keys, and the connection to the bars is set so lock and release positions are definite.
Scene 3
The manual lock is now your plan for a dark evening. The sequence is simple: with the door closed, pull the opener's release cord so the trolley disconnects, then throw the slide bolt or turn the T-handle to lock. In the morning, or when the power returns, reverse it exactly: unlock first, confirm both bars are clear of the track, then re-engage the opener as its manual describes, usually by running it once so the trolley picks up the arm. The technician walks through this with you at the door, and it is worth practising once so the order is second nature before the storm that makes it matter.
What shapes the quoteBroughdale Garage Door Specialists
FeesSame any hour
The knob is meant to grip the square spindle with a set screw, and that screw has loosened or the spindle's flat has worn so the knob no longer bites. Sometimes the spindle itself has sheared inside the door. The technician tightens a fresh set screw onto a proper flat or fits a new spindle of the correct length, and the knob and outside handle move as one again.
Something in the short chain between the handle and the bars. The square spindle may have twisted or sheared, the set screw holding the inside knob may have let it spin free, the cam inside the centre body may have worn round, or the return spring may have snapped. The inside cover comes off to see which, and the failed part or the whole mechanism is replaced to suit.
Whether the lock is an inside sliding bar, an outside T-shaped handle with a key, or both; whether the handle turns and whether anything moves when it does; whether the key goes in and turns; whether an opener is fitted and whether it has ever run with the lock engaged; the door's material and age; and whether you hold a key. A photo of the inside of the lock is useful.
