Rim Cylinder Locks

Rim cylinder locks are the classic companions of your trusty nightlatch. After all, these surface-mounted locks we find on countless British doors are specifically engineered for rim locks and nightlatches. These specialised cylinders mount directly onto the door surface instead of being inserted through the door thickness. And that makes installation wonderfully (and sweat-free) straightforward.

Unsurprisingly, rim cylinder lock replacements are great for retrofitting security onto doors where cutting mortises isn’t practical or desirable. No wonder many tradespeople across the UK use these locks on period properties and even rental units where modifications are limited.

These are ideal for wooden doors and shed entrances, although internal security doors requiring a simple latch operation can benefit too. Rim-type cylinder locks pair beautifully with nightlatches for quick-exit convenience while maintaining external key security.

Our collection of replacement cylinder rim locks features a variety of products, from budget-friendly options to high-end, robust versions. Many have drill-resistant pins and anti-pick mushroom pins to enhance protection. We even have brand-specific cylinder locks, like the Geg pExtra Plus Ingersoll Rim Cylinder.
