Exterior Door Knob Lock Cylinder Replacements

When installing deadbolts on the exterior doors, using a standard mortise-lock is used, if the door does not have a deadbolt already attached. The new installation may need to use new deadbolts or it may need to be converted to an existing lock after which the existing deadbolt may need to be replaced with a new one. In this case the door knob lock cylinder and a deadbolt may need to be purchased or made if it is not available from the dealer. If a standard lock cylinder is used, one should make sure that it matches the hardware used on the door.

To replace the interior door locks, one can either cut a hole in the exterior doors using a reciprocating saw or he can purchase a door knob. A doorknob is a special type of lock that has a handle on the outside and a knob on the inside. It means reconfiguring both the exterior and interior door locks. Inside, the new door knobs and the holes drilled in the exterior doors would need to cover the holes made for the new mortise locks.

To make use of the existing door locks, one can utilize the existing key to operate the door knobs and the holes in the doors. One should note that in most instances these types of door locks will only operate on the interior side. To make use of them on the exterior side, one needs to install a heavy duty deadbolt. These kinds of door locks are usually rated in thousand-dollar ranges and are made of solid steel. They may also come with a tumbler that is made of vitreous China.
