Why Does a Key Break Off Inside a Lock?

Keys made with substandard materials or inaccurate duplication are more prone to breaking.

When keys get stuck, users often force them to turn, increasing the chance of snapping.

Extreme temperatures, especially cold, can make metal brittle and more susceptible to breaking.
