Lock Re-key

I remember a few years ago I got a call from a customer who needed to re-key all the locks in his home. Like most locksmith technicians, once I got to the customer's home, I inspected the locks that needed to be re-keyed for compatibility making sure I could key them all the same. Most of the time its not a big deal, but In this case, the customer had four doors where each one of them had a Titan deadbolt and a Corbin entry lock. 

The first step for me was pulling all the locks. Before starting re-pinning all the locks, I did a little testing. I noticed that I was able to use the new key I made for the Titan deadbolt on the Corbin cylinder, but only when the plug was out of the sleeve. I then had an idea to grind the bottom surface of the blade about 1/32" and the key seemed to fit in the Corbin Plug even after re-pinning and assembled it. I finished re-keying all the other cylinders, put them back in the door and the customer was satisfied since now he had to worry about only one key instead of two.

Luckily, I got this idea from a Reno locksmith co-worker of mine who recommended me to always have a set of around six keys made for each common lock manufacturer before any re-key job. That way, the next time I will face a similar job, I would come prepared and save some time. It seemed that in this area, the most common lock manufacturers are Schlage, Kwikset, and Multilock, so now I have a set ready for each one of them which will save me the time of cutting them on job location.
