- The call
- The power is out in a storm, you pulled the red cord and lowered the door by hand, and now you want to lock it. The slide bolt on the inside edge is welded in place by years of rust and refuses to budge.

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.
Many lock complaints turn out to be door complaints. The bar on a slide lock or a T-handle has to land in a small slot, and it only gets there if the door stops exactly where it stopped when the lock was fitted. A floor that has heaved, a track bracket that has loosened, a bottom seal that has flattened, or ice under the door all shift that landing point. The visit begins with the door: closed by hand, checked for level and for how it meets the floor and the tracks. With the door where it belongs, the lock often needs only a small adjustment to its guides.

Scene 1
Garage doors carry a few different locks and the first job is to name the one in front of the technician. An inside slide bolt is a short bar on the door's edge that shoots through a slot in the vertical track; some are snap latches that lock on their own when the door closes. An outside keyed T-handle or L-handle works a centre mechanism that throws a bar into each track, or on some models pulls a cable to release a spring latch at each side. Some doors have a keyed cylinder on the side that operates the slide bolt from outside. Each has its own parts and failure points, so naming it correctly sets up everything that follows.
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.
