Single sided deadbolt
 
Hey folks,

I have a new metal entry door with wood sides. It's pre drilled for knob and deadbolt. I wanted to install an additional single sided deadbold. The factory drilled holes had wood under the metal skin. I incorrectly assumed the wood would go high enough to put another hole, but it's just foam.


Is a second bolt in this area not recommended? Has anyone else done this? Any way (or need) to reinforce?

Thanks!

Why would you even want to add one?

My deadbolts are keyed on both sides, I want to add a thumb latch so I don't have to fumble with the key all the time on inside.

Change the inside to a knob/latch -
the dead-bolt.
A dead-bolt, through the foam is useless -
It looks impressive, though.

The door has already been cut, can't change style.

Just pick up a new lockset with handle & deadbolt and be done. Then just keep the other in a plastic bag with the parts & keys, or donate to local Habitat store for someone else to buy.

A keyed both side is againt code in my area.
What do you do if there's a fire? Go looking for your keys?

Take a wood chisel and remove some of the foam core from the top and bottom of the hole. Cut some wood blocking that fits snuggly from one skin to the other. 1/2 inch plywood blocks about an inch wide work. Use at least one in the top and one in the bottom. More is better if you can get them in around the perimeter of the hole. When you tighten the clamp screws on the deadbolt, it will pinch the wood blocks between the metal skins and they won't move. Without the blocks, the core will just crush together and the lock will never be tight. There was a company that used to sell a corrugated metal expander for this purpose, but I've not seen any in years.

Thanks M6!

I was able to find some small pieces of exhaust pipe that was the exact diameter I needed. I cut it to fit and machined a couple holes for the deadbolt to slip through. Was only about 5 dollars and about 30min to get it all machined.

I'll try and post a few pictures.

Thanks again!
