These are the only pictures I have of the patio door that give anything close to a model number I need to purchase a new cylinder lock as the keys were lost.

Thanks for posting. You should be able to replace the old key lock cylinder with our 82-310 (which comes with its own set of keys). This blog article here goes into more detail about the replacement process.
