Deadlock Installation Manchester — BS3621

A BS3621 5-lever mortice deadlock is the British Standard lock required by most home insurance policies on external wooden doors. Without a BS3621 deadlock, your insurance company may refuse to pay out on a burglary claim. We supply and fit BS3621 certified deadlocks from trusted UK manufacturers, morticing them cleanly into your door for a professional finish. If your wooden front door or back door doesn't have a BS3621 deadlock, you should consider fitting one immediately.

We fit deadlocks to all types of wooden doors including panel doors, ledge and brace doors, and solid timber doors. The lock is morticed into the edge of the door and a corresponding keep is fitted to the door frame. We ensure precise alignment for smooth operation. All our BS3621 deadlocks come with two or three keys, and we can supply additional keys if needed. We also fit 3-lever deadlocks for internal doors or locations where insurance-grade security isn't required.
