Buying guides for buying a deadlock

• When you buy a deadlock, make sure that it is the right type of lock for your needs. There are three main types of locks: Semi-deadlocks, full deadlocks, and half-deadlocks. You need to be aware of the differences between these three types before you buy a lockset.
• If you are buying a semi-deadlock, make sure that it is suitable for use in your home or business premises. There are different kinds of semi-deadlocks, including deadlocks for internal doors and deadlocks for external doors. You also need to take into account the level of security that you want from your lock. High-security semi-deadlocks are harder to pick than standard locks, which makes them ideal if you need a high standard of protection.
• When buying a full deadlock, you should make sure that it has the correct measurements for your door. Locks come in different sizes and lengths so make sure that the lock you buy will fit on your door as well as be suitable for its purpose. Some locks are designed to be used with an anti-drill plate or other extra security equipment, so always check whether the lock you are buying already comes with any extras.
• Finally, make sure that the deadlock is suitable for your door material and any other requirements that you have. For example, if you need a fire-rated lock to be fitted on an internal door in a high-rise building, make sure that it meets the relevant safety standards.
