    What is the most effective mortice lock?


    Is a 2-3 lever mortice lock more secure and effective than a five-lever mortice lock? Why/why not? Thank you!

    There are not more secure or as effective as the 5 lever locks.

    Reason: what you want is a 5-lever British standard. Which means it's been tested against regulations and standards.

    The 5 levers as the names suggest have 5 levers in them rather than 3 or 2. Effectively this means 3 or 2 levers or easier to by pass."

    "Hi Patrick. A 2-3 lever lock is usually used on internal and bathroom doors while a 5 is a more secure lock used for front and rear doors. A British standard 5 lever lock would be most effective and secure as it includes anti-Burglary features such as a curtain, anti-pick notches, reinforced bolt and additional plating to protect against drilling. Insurance company’s usually ask home owners to fit British standard lever locks to their front and rear door."

    "The 5 lever mortice is more secure as there are more combinations than a 2 / 3 lever lock.
    The best one is a 5 Lever BS3621."
