Key with 4 cut sides N-S-E-W?

[kb9tke]

I am new to lock picking and have successfully picked quite a few in the few weeks that I have been doing it. But, I was in a WallMart the other day and saw a lock box made by Sentry that had a key that had 4 nodes on it and all four were cut with a different cut. If you turned the key so you were looking at the key from the OPPOSITE end of the Bow it looked like a plus sign. Is there a name for this type of key? Looks to me you would have to pick it on all four nodes. Anybody have any information about this kind of key or lock? Thanks for any information and this looks like a well run forum.

I've heard these referred to as "cruciform" keys - I recall seeing a pick for these in the HPC catalog but I have never encountered one "in the field" although a colleague had a cheapo steering wheel lock that used one.

these are made in brazil by a company called papiaz, or something like that, if you look at the key, straight on so that it looks like + you should find that one of the legs of the key is thicker than the others, this is so you can only put it in the lock the right way. also, there are probably no pins or cuts on this leg of the lock, the other legs have three pins each so you are looking a a nine pin lock, if you want to pick it, you will have to make a tension tool to fit the thick leg of the + and then you can pick the pins in each of the other legs. I haven't picked one of these, but I believe that it is not tightly machined or full of security pins, if anyone has better information, correct me.

if I remember well this kind of locks have been invented during the last WWII time in Germany

you can open them with a "cross pick" in a matter of seconds
