I bought this lock at Rona because I was curious about how it worked.
There are two "security" type screws plus one of those screws shaped so it can only be tightened. 5 minutes with a 1/16 inch drill fixed that, and I removed it with a standard slot screwdriver. My iFixit screwdriver kit had the right screwdriver to remove the little triangle screws.
This actuator has four posts which move some plastic wheels in the lock housing. It's interesting to note that two wheels are moved at once.
Right wheel is in the lock position.
