anyone know the process for making a key for a lock without one to copy?
If you have free access to the lock cylinder, a traditional method is to disassemble it (typically from the back). Some locks have a slider over the pins and springs that can be removed, and the lock cylinder disengaged and taken out. Otherwise, the cylinder generally can be removed by bumping or picking the pins to open it somewhat, and then pushing it out with a similarly-sized dowel (which keeps the tops of the pins and springs from spraying out all over the place once the cylinder is removed).
Anyhow, once the cylinder and lower parts of the pins are out and free, it's a process of inserting a key blank, marking where the pins land, and filing down the valleys until the pins will all sit flush with the cylinder when in their respective holes. It is, of course, quite important to avoid leaving any vertical cliffs in the key teeth so that the key can be inserted and removed from the lock.
I successfully did this for my garage door lock, which did not have a key supplied by the previous homeowner when I bought the house. The result wasn't quite as smooth and reliably working as a factory key, but perfectly adequate and I thought pretty decent for a first attempt by a decided amateur.
