- A member of the Master Locksmiths Association can check if your door is secure and solid timber or of robust composite construction. The locksmith can also reinforce the frame (with London and Birmingham bars) and check if the locks and hinges are British Standard approved.
- Ideally, the door and frame should be of solid construction with a British Standard mortice lock and an automatic deadlocking rim latch.
- Always remember to use both locks and check to make sure that the mortice lock is engaged every time you leave your home.
- If your door has a letterbox, a letterbox guard fitted to the rear of the door will prevent someone from reaching in and opening the door or fishing for any items nearby. Consider cat flaps as well, and position keys and valuables away from the door opening.
- Modern multi-locking and UPVC doors use a system of hooks and latches to secure the door, but these only work if you lift up the handle and then remember to turn and remove the key.
- Glazing can be reinforced by using special film or by installing laminated glass panels.
- Door viewers or restrictor chains are recommended so that visitors can be identified before opening the door.
- A timber back door will require a British Standard mortice sashlock in the centre of the door, with either rack bolts or surface-mounted lockable bolts in the top and bottom corners.
