I found the same. I managed to unlock my workshop's Yale lock using a heavy duty paper clip snipped in half to form the two tools. My first attempt picking a lock, and took about 10 minutes of fiddling.It's scary how easy it is to pick a standard front door Yale type lock with the right tools. A few years ago I had to call out a locksmith to get me into my house after the front door lock completely failed. He opened my side door ( same type of lock ) with what looked like a small battery powered drill that vibrated rather than rotated, in about 5 seconds. Cost me about £95 for the call out iirc.
Can you explain the ‘rack up and down bit’ please @ArvI've always found the easiest way is to get a key that fits in the lock and rack up and down and twist. Normally gives up in less than 5 mins. Same thing seems to apply to uPVC doors too.

That’s why when I had my front door made I had Ingersoll London Line locks fitted, good luck picking them or kicking the door in.It's scary how easy it is to pick a standard front door Yale type lock with the right tools.
