The expression is 700 or 800 years old. It obviously refers to making doors with the use of nails.

A really good one is "dead as a doornail".
William and Mary Morris, in The Morris Dictionary of Word and Phrase Origins, quote a correspondent who points out that it could come from a standard term in carpentry. If you hammer a nail through a piece of timber and then flatten the end over on the inside so it can't be removed again (a technique called clinching), the nail is said to be dead, because you can't use it again. Doornails would very probably have been subjected to this treatment to give extra strength in the years before screws were available. So they were dead because they'd been clinched. It sounds plausible, but whether it's right or not we will probably never know.A doornail is a fingernail that was slammed into a closing door. It is extremely painful, then dies; it hemorrhages, turns all black and blue and eventually falls off.

A doornail (coined c. 1350) is a very large studded nail on the outside of wooden doors, often used to nail on the metal strips which gave the door additional strength. They were also used as an ornamentational device. The more expensive homes had these metal, heavily-studded nails rather than wooden pegs, like the regular folks had. The doornails were 'clinched' on the inside of the door to prevent theft and give additional strength. Once clinched, the nail is 'dead', as in, it cannot be used again for that purpose.
