Champion Keyed Handle Set

I have a patio sliding door from Champion. The mounting screws are 6" on centers. The problem is the lock ruins keys on a regular basis. The key blanks available are to long and have to be cut to length. This results in one out of four keys cut working for a time. I would like to replace the complete mechanism. Beige or glossy brass.
It looks similar to the brass one in the video but larger.
Do you have anything available?
Thanks
