Pins
I was just wondering if someone could give me some info on security pins. I am not a locksmith so please excuse me if my questions are basic or "dumb".
I would like to make a challenge lock. I saw a lock the other day that had an interesting keyway. I believe it is called paracentric? I think. Anyway, the padlock interested me and I'd like to go back and buy it. I asked the locksmith at the counter if the lock had any security pins in it because I'm looking for locks that have higher security pins in them. He stated "No" to the security pins. Anyway, it is a schlage padlock. I saw on CLK web site and found that they sell security pins. I'm wondering if the pins are all interchangeable or how do you know which pins to buy?
Would any schlage driver pins fit? Or would I have to buy a micrometer and measure length and diameter of the driver pins to match them up? Does changing the driver pins also change the biting on the key? So, if I swap out reg driver pins for security pins will I have to have another key made for the lock???
Any advice or info is appreciated.
