They use allen keys.

I maybe thought Rivets or Robertsons screws (square headed screw.)

Robertsons? What are they, Canadian made?! (Hey, sorry to all Canadians.... just a little harmless fun, eh......... Go Leafs! )

[Mad Mick]

Robertsons are an internal square drive, instead of a hex like an allen screw. AFAIK, there are three common sizes.

these locks have allan key screws holding the lock on the door. However there is a black steel plate that protects these screws when the door is locked. Hence you need a key or have it picked as when you turn the key the plate turns as well until a gap appears allowing you to insert a allan key and remove the lock. The screws stay inside the the lock drum so dont ruin the head thinking you will replace them.
