Why Your Car Key Is Wearing Down — and When to Replace It
Worn car keys are a common cause of snapped keys and lockouts. How to spot a key that's close to failure — and how to prevent an expensive emergency.
Signs Your Key Is Wearing Down
Difficulty turning in the ignition or door lock. Occasional slip when turning. Visible thinning of the key blade, particularly at the cuts. Key looks 'shiny' or smooth at high-friction points.
Why Worn Keys Are Dangerous
A worn key can snap inside the lock or ignition at any time — turning a minor inconvenience into a full emergency callout. The break often happens at the thinnest cut point and can occur without warning.
Get a Spare Before It Breaks
The best time to get a spare key is when you still have a working original. A locksmith can cut and programme a new spare from your existing key while it still functions.
What If the Key Is Already Too Worn to Copy?
An experienced auto locksmith can decode your car's lock to produce an accurate new key without relying on the worn profile. Key 2 BHP carries decoder tools for this scenario.
