Installing a doorknob is a fairly simple task if you are replacing one. It requires a bit more attention if you are adding a dead bolt or attaching it to a new door.

First, measure the width of the door. Some doorknobs are adjustable in depth and others are not. Securing a replacement that matches the bore of the holes is easiest, but enlarging a hole or adjusting the strike plate is not difficult.

Most door knob kits come with a paper template that can be attached to the door before drilling. It is extremely important to drill in the right place or the latch will not fit properly. A hole is very difficult to re-drill. In some cases, a piece of wood must be added to the door and the door is then refinished.

Make sure you have the proper screwdriver. Most screws have a combined head that will work with a Phillips or a flat head screwdriver. Occasionally you will need an Allen wrench or other special tools. Find out what tools are needed and secure them before you attempt the job.

Removing the doorknob may take a little patience. Depending on the type of knob assembly, it requires pushing it a pin or bar before the handle can be removed from the inside of the door. The screws are located beneath the trim. This is the ring that surrounds the doorknob and fits tightly against the door. Some have screws, but most do not and can be pried off by using the screwdriver. Be careful not to mar the wood. Remove the screws that go through the door. The knob should then be easily removed. Replacement is just the reverse of the directions. If the replacement is not exact, follow the printed instructions that come with the doorknob.

Test your work to be sure the doorknob fits properly, the strike is not keeping the door from closing or locking and that you can secure and unlock the door. Except for passage doors, they lock. Some privacy locks come with a pick. A nail or small piece of coat hanger, etc. works in most cases. 1 very small screwdriver is a good investment.

This is an excellent time to check the screws in the door hinges. When they become loose, they can affect the door alignment and tightening them first can avoid having to adjust the strike plate.

A good repairman cleans up after himself. Some have a recycle bucket that they throw the brass knobs into, and can recover a good bit of money over time for their effort.
