I have a Gatehouse Single Cylinder Deadbolt it's a grade 3 lock but what the hell, I have gotten open a automotive lock and a few others but this one is a pain. I am not sure if it has security pins or not because I am hitting the pins and putting a bit of tension on the cylinder but she wont budge I hear the pins click also when I get them locked in but when I let off a dash of tension they reset so yea. If anyone can help me out I'd appreciate it. This is a practice lock also I learned that and built myself a Dummy door =D. But yea I hope someone can help me figure this out. Thanks again guys.
