Backyard sliders and condo balconies in Burlington collect grit in the track by late fall; locks miss because the panel sits a few millimetres out of square, not because the lock body failed first.
Non-locking sliders near Appleby and Brant
Around Burlington, the panel has usually dropped so the hook misses the keep. Halton Door Repair Co. raises rollers first; lock bodies come second.

Common questions
Quick answers to what homeowners and property managers ask most about this problem.
Why does my patio door handle turn but not lock in Burlington?
In Burlington, the lock hardware is working, but the panel is out of alignment. Worn rollers, a dirty track, or a shifted keeper plate prevent the hook bolt from entering the strike. The handle spins because the internal linkage moves — the catch points simply miss. Roller replacement and keeper realignment fix most cases without a new door.
How often should I clean a sliding door track?
In Burlington, vacuum the lower track at least twice a year — more often if you have pets, heavy yard debris, or a walkout that gets sand and salt tracked in. Dry tracks help rollers last longer and keep the panel at the height the lock was designed for.
Can worn rollers cause lock problems?
In Burlington, yes. When rollers flatten, the panel drops a few millimetres. The lock tongue may pass above or below the keeper even though the handle feels normal. Replacing rollers and setting panel height usually restores locking without changing the lock body.
When should I replace the whole sliding door?
In Burlington, if the frame is twisted, the track is corroded through, or the glass seal has failed, replacement may make sense. When the frame is square and the glass is sound, roller, track, and lock repairs are typically far less costly and finish in one visit.
Is sliding glass door repair the same as patio door repair?
In Burlington, yes — both terms describe the same systems: glass panels on rollers in a track, with foot locks or hook bolts at the frame. We repair rollers, tracks, handles, and lock bodies on site when the frame is still sound.
