Lock Bumping and Bump Keys: How to Protect Your Home
Lock bumping is a quiet, quick way to open many standard locks. The good news: anti-bump cylinders make your door far harder to beat.
What is lock bumping?
Lock bumping uses a specially cut 'bump key' tapped into a standard pin-tumbler lock to momentarily jolt the pins and turn the lock. It's quick and quiet, and standard euro cylinders can be vulnerable to it.
It leaves little evidence, which can complicate insurance claims after a break-in.
Which locks are at risk
Basic, cheaper euro cylinders are the most vulnerable. Higher-security cylinders include anti-bump pins and other features that defeat the technique — often the same cylinders that are anti-snap and anti-pick.
If your UPVC or composite door has an unbranded standard cylinder, it's worth checking.
How to protect your door
Upgrading to a quality anti-snap, anti-pick, anti-bump cylinder (TS007 3-star or Sold Secure Diamond) closes off bumping, snapping and picking in one go. It's a quick, affordable swap that fits your existing door.
We supply and fit high-security cylinders across Catford and South East London — ask us to check your current ones.
