What Anti-Snap Lock Upgrades Covers

Lock snapping is the most common way burglars beat a uPVC or composite door, and it takes seconds with tools sold openly online. An anti-snap upgrade is the single highest-impact security change most homes can make. Doctor Locks fits genuine Ultion cylinders, which sacrifice a section under attack while a hidden lockdown keeps the door secure, and we size every one so it sits flush with the handle, leaving nothing to grip.

Authorised Ultion installer - verified by the manufacturer
£5,000 manufacturer guarantee if the lock is defeated by snapping
Anti-snap, anti-pick, anti-drill, anti-bump protection
Suitable for most UPVC and composite doors
Cylinders checked for protrusion and fit before leaving
Existing door handles and hardware retained where possible

Ultion £5,000 Guarantee

Doctor Locks is an authorised Ultion installer. Every qualifying anti-snap cylinder installation comes with a £5,000 manufacturer guarantee against lock-snapping.
