When you insert the key and start to turn the tumbler, it will expose a pin at the top of lock, that pin has to be pulled out and the tumbler will come out. I can't find mine as usual or I would post a picture.
I got it, Thanks Guys! of course there's another problem, the new location is full of rusty corrosion, plastic plunger piece is stuck, gonna have to soak and wire brush it clean before inserting, always something.
About 1/8 to 1/4 turn of the key then depress the pin in the hole above the cylinder, can use a paper clip. Once depressed pull on the key and the cylinder should come out. Moving the key from the retraction point will cause the pin to extend and keep the cylinder in place.
