I got a call to an office, today. They had 9 lockset on the offices, all Sargent 6-line. They had lost the key, and would like another key made. believed to be keyed alike.
They did finally find a key, and so it was just a case of make three dups. But how to go about it?
The 6-line is a 6-pin, sargent cylinder with LA keyway. Miserable to pick.
Can I dissemble them like the old Schlage A-53?
