Cabinet Lock Repair

A jammed cabinet lock, fixed on the spot

October 2026. Isaac had it working again before Andy finished packing up. Same lock, same key, no replacement.

The problem

Maritza, who runs the Good Heart Cafe on Glenmore Trail SW, had an antique cabinet whose lock would not work. It is a cabinet lock with a little lever inside and an old bit key, and it is pinned together, so it is not really meant to be taken apart and serviced. When one of these breaks, most likely you need to replace it. This one was jammed.

The cabinet is an antique, and it is not just furniture to her. She bought it at an estate sale from a couple in their nineties. It was the first piece of furniture they bought together when they moved in. That is why the answer was never a new lock.

The cafe is a family place that makes its food from scratch, and with her blessing we name it: goodheartcafecalgary.com, 1011 Glenmore Trail SW. Local businesses helping local businesses.

The lock itself was jammed in an awkward position, so I just had to wiggle some things free, but now it's working fine. Isaac, describing the repair on the video.

What Isaac did

Isaac was there with Andy, who was packing up to leave. The owner asked Isaac if he could look at it. He took the lock off the door and had it working again before Andy was ready to go. Andy picked up Isaac's phone and took these pictures while he worked.

He poked around inside the case for the leverage points, to find where it was binding. He found two levers that had to be pushed in before the tongue (the part that shoots out and locks) would come out any further.

In the end he took pliers to the tongue and pulled until the broken mechanism came free. From then on it worked. No lube, no new parts.

The video

Andy filmed it: the jammed lock, the fix, and the key locking and unlocking it again. Forty seconds, and it loops; sound on when you press play.

Nice job, Locksmith. Andy Leung, David Locksmith, filming the repair.
Got an old lock that is stuck?

An old lock that still has life in it is usually a repair, not a replacement. Bring it in, or text a picture to 403-280-2993.
