At first glance, a car key seems tough enough. After all, it’s made of metal, right? But the truth is, car keys are surprisingly fragile. A fall onto a hard surface, an awkward knock in your pocket or even day‑to‑day wear and tear can damage them far more than you’d expect.
One of the most common (and most inconvenient) breakages is when your car key snaps in half. Once that happens, it’s impossible to start the car and if your car key snapped off in half no spare, you’re not just dealing with a broken key, but with being completely locked out of your own vehicle.
In this article, we’ll explore why it happens, how to avoid it and what to do next.
It’s a scenario most drivers dread: you turn the key to unlock the door, and it shears clean off, leaving part of it stuck inside the lock.

It often happens when someone forgets the blade isn’t meant for daily use, but only as an emergency backup.
