Sliding door lock

Unfortunately this isn't the first time this problem has come up. The manufacture of the key cylinder 82-310 used in the 82-086 handles set states that it uses the Kwikset key way, but I personally did not find it at all easy for a locksmith to make up Kwikset keys to fit, so I'm really not sure if you want to go through the trouble. Have a locksmith take a look at the 82-310 key cylinder and ask them about a Kwikset key way.
