The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn't an option, but eliminating the need to use a key was.

I used a couple of pieces of acrylic that I acquired in the dumpster of the plastic shop next to my place of work (they throw out alot of small pieces like this). Alternatively another material could be used if you don't have access to acrylic, but it is easy to work with and looks cool.
Using a piece of paper trace the mounting holes for your dead bolt and transfer them onto your acrylic sheet. Since most dead bolts are going to be slightly different I am not sharing the template I made out of a piece of paper (mainly because it isn't anything worth sharing).
Leave the paper covering on while working with the acrylic. The paper makes it easy to mark where to cut/drill as well as protects the material from scratches. Once all of your cuts are made and your holes are drilled you can start installing components such as LEDs and switches.
