Asec Vital 3 Lever Deadlocks - Brass or Nickel Plated

Not every door in your home or workplace needs the same level of security. External front and back doors are a different conversation — but for internal doors where you simply want a reliable, key-operated deadlock that does its job day in and day out, the ASEC Vital 3 Lever Deadlock is a solid, well-specified choice that won't let you down.

This is a mortice deadlock, which means it sits neatly inside the door rather than on the surface — giving a clean, flush finish with no unsightly case or backplate on show. The 3-lever mechanism provides dependable security for internal applications, and the reversible bolt means the same lock fits both left and right-hand doors straight out of the packaging. No need to order different variants for different doors on the same job.

Two keys come in the box as standard. The deadbolt itself is brass, giving it good resistance to wear over time, and the lock case is available in two sizes — 65mm with a 44mm backset, and 75mm with a 57mm backset — covering the most common door preparations found in UK residential and commercial properties. Both sizes are available in Polished Brass and Nickel Plated finishes, making it easy to coordinate with existing door furniture and ironmongery.

On the credentials side, the ASEC Vital 3 Lever Deadlock carries Certifire approval and conforms to BS EN 12209 — the European standard for mechanical locks. For a 3-lever deadlock at this price point, that's a reassuring level of independent verification.

ASEC is a well-regarded name across the UK locksmith and hardware trade, and the Vital range represents straightforward, reliable locking hardware without unnecessary complexity. If you need extra keys for additional copies, they're available separately
