Don’t panic—and definitely don’t reach for glue
The moment a key snaps in the lock, your brain usually offers two terrible ideas: force it harder or try some internet “hack” that sounds clever in the moment. Resist both. Pushing the fragment farther in can wedge it more tightly, and superglue is one of the fastest ways to turn a manageable problem into a lock replacement. Locksmiths constantly warn us that glue can permanently bond the broken piece inside the cylinder, which makes later extraction much harder and can damage the lock itself.
