The handle turns in your hand the way it always does, and the door stays exactly where it was. No click, no give, nothing at all. Most people try it again harder at that point. Try not to. The failed part may be small, and forcing the handle can turn a minor repair into a damaged handle set.

The problem may be in the handle, the latch, or the way the door is sitting in the frame. Before assuming something has broken, start with the simple things you can rule out yourself.

If the trouble is a key that will not turn in the lock rather than a handle that spins, that is a different fault with different causes.

If Somebody Is Shut In Behind the Door, Deal With That First

Try the handle from the other side of the door if you can. Some handle failures affect one side before the other, so the door may still open normally from that side.

If it will not open from either side and somebody is trapped behind it, call for help rather than forcing the door. Force can damage the lock, door and frame, and it can put the person on the other side at risk.

Four Things Worth Ruling Out Before You Blame the Hardware

Before assuming the handle or latch has failed, check that nothing else is holding the door shut:

How a Handle Is Supposed to Move the Latch

It helps to know what is inside the door, because most of what follows makes more sense once you can picture it.

On many lever handles, a metal spindle runs through the door and connects the two sides. The handle may be secured to that spindle by a small set screw, usually underneath or behind the lever. Other doorknobs and handle sets use different internal fittings.

When you turn the handle or knob, the internal mechanism should retract the latch from the frame.

That leaves three useful things to check. The handle may no longer be operating the latch, the latch itself may be stuck or broken, or the latch may be working while the door is binding in the frame.

Start With a Loose Handle

If a lever handle feels floppy or moves farther than it used to, check whether the set screw has worked loose. The handle is turning on the spindle rather than turning it, so nothing is reaching the latch at all.

If your handle uses a visible set screw, this may be as simple as tightening it with the correct hex key:

If the Handle Feels Normal and Nothing Moves Inside the Door

When the handle has the same weight and resistance it has always had, but nothing at all happens inside the door, the fault is in the latch mechanism itself. That sits inside the edge of the door, where there is no way to see it or get at it while the door is shut.

Wear, corrosion or debris inside the mechanism can keep the latch from retracting properly. Sometimes there has been some stiffness or hesitation before the latch finally stops working.

If the latch is not retracting and the door is already shut, avoid forcing or digging into the hardware from the outside. A failed latch is usually replaced rather than rebuilt. Depending on the lockset, the latch may be available separately or the handle set may need replacing with it.

If You Can Hear the Latch Pull Back and the Door Still Will Not Budge

Turn the handle slowly and listen. If you can hear and feel the latch retracting cleanly, then the lock has done everything it was asked to do and the problem is somewhere else entirely. The door itself is being held in the frame.

A common clue is a door that opens only when you pull it toward you, push against it or lift it slightly while turning the handle. That usually points to pressure or alignment at the latch and frame rather than a handle that has stopped working.

If the latch is retracting but the door still will not open, check what may be holding the door in the frame:

The same alignment problem can also keep a deadbolt from entering its strike fully. If the deadbolt only partly engages, that is worth correcting rather than treating it as a sticking-door problem.

How to Tell When It Has Stopped Being a Small Job

A handle that has started spinning needs checking rather than more force. Continuing to force a loose handle can damage the spindle or other parts and turn a simple adjustment into a replacement.

Call for help if the handle spins with no resistance, if you are having to force the door with your shoulder, or if this is the only practical way in or out of the property.

If somebody has ended up shut in or shut out because of it, lockout service covers what happens from there.
