[putting on Legal Hat for just a moment]
You're going to have a hard time trying to find anything that says "lockpicking" anywhere in PA's Consolidated Statues. Basically, what you are going to find is that PA is one of the states where "lockpicking tools" aren't specifically addressed, and "intent" is more important.
I don't have my crimes code in front of me right now, but in PA, Title 18 is the criminal code, and what you want to look for are Inchoate Crimes
. I believe that is Chapter 9 of Title 18.
The only thing I have ever seen anyone charged with that you will probably need to be worried about, at least in Philadelphia, is known as PIC, or Possession of an Instrument of a Crime. If you don't have a legal background it might look rather odd, it's nestled in there with body armor and firearms or other weapons.
In plain english, it's a misdemeanor to possess an "instrument of a crime" with
the requisite intent to use it.
PIC is basically a modifier, it's typically used to enhance another crime. I have never seen anyone charged with JUST PIC, but that doesn't mean that it's not possible.
But be warned, if I remember correctly, PIC is a First Degree Misdemeanor, which means you could actually get jail time for a conviction.
Hope that helps.
Oh, it's also a BIG deal to have what is refered to as a "Vehicle Master Key" that you will face charges for and it is also a First Degree Misdemeanor. And believe it or not, a "master key" is defined as any key that can open more than one lock. So, if you make, have, or give anyone a key that can open 2 or more cars, you'll probably want to get rid of it.
