Looking at Alastair's blog inspired me to rekey my '82s sliding door
lock. (PO put in a later/longer handle with a different key)

It looks like a punch(?) being used?  Anyone have a DIY source for the
tools/parts/instructions needed to punch(?) this out and replace the
pin/screw or whatever is holding the tumbler in?
