The holes to remove the cylinder should be on the side of the lock, not below. Look at Han Fey's Abloy Classic PDF on toool.nl (down at the moment or else I'd link you...) The cutaways in there show how it works. I'd guess trying to pry off the bigger retaining screw first will be real bad for the lock...
dg, I have seen han's abloy page and my lock doesn't have any holes. When return home next week I will send pictures so you can see the lock, thanks for the help. Cheers, -XIII
Locks are to jigsaw puzzles like keys are to the picture on the box
