Oval Profile DeadLocks
Oval Profile DeadLocks for Timber & Heritage Doors
Oval Profile DeadLocks are a secure, key-operated solution designed for timber doors, heritage sites, and commercial buildings still using traditional oval profile cylinders. These mortice deadlocks offer dependable locking without a latch, making them ideal where doors are always locked when closed.
What is an Oval Profile DeadLock?
An oval profile mortice deadlock is installed into a mortice in the door edge and uses a removable oval cylinder to throw a solid deadbolt. Unlike a sash lock, there’s no latch — only a deadbolt for secure locking. It’s often used to replace existing oval profile locks without the need to change other hardware.
Pros & Cons
- Pros: Maintains existing master key systems, upgradeable cylinders, secure deadbolt action.
- Cons: Fewer models available than Euro profile, less choice for modern upgrades.
Sizes, Finishes & Matching Hardware
Common oval profile deadlock case sizes are 2.5" (≈44 mm backset) for standard doors and 3" (≈57 mm backset) for thicker frames or fire doors. Available in satin chrome or polished brass, they pair perfectly with oval profile escutcheons. For sash lock installations, match with lock door handles on backplates.
When to Choose This Lock Type
Ideal for schools, hotels, offices, and listed buildings, these locks ensure you keep a consistent keying system without a full hardware overhaul. For other options, see Mortice Locks & Latches or Locks & Latches. We deliver to London, Manchester, Birmingham, Leeds, Glasgow and across the UK.

How to Select the Right Oval Profile DeadLock
UK Sizing, Backset & Finish Selection
When replacing an oval profile mortice deadlock, measure from the door edge to the centre of the keyhole (backset). Standard UK timber doors use 2.5" / 44 mm backset cases, while thicker doors and many fire doors use 3" / 57 mm. These locks are ideal for heritage building restorations, commercial security upgrades, and maintaining master key suites without changing every lock. Available in polished brass for period properties or satin chrome for modern interiors, they are compatible with Oval Profile Escutcheons and other Door Furniture. For related categories, see Locks & Latches, Mortice Locks & Latches, and Oval Profile Locks. Delivery is available to London, Manchester, Birmingham, Glasgow, Edinburgh, Cardiff and across the UK.
