Im looking to get either SC1 or SC4 bump key but i was wondering if I insert an SC4 bump key into a SC1 lock or a SC4 into an SC1 would there be a possibility of the key being jammed in there?

If the lock has a stop plate, you could destroy that if you were bumping like a maniac. Looking at the original key can fix this problem. Additionally, you could count the pins manually to see which one is appropriate - a simple feeler pick is good for this task.

well, the key to the mail box room which I own has a 5 pin SC1, so im assuming that all the other doors would be SC1 it wouldent make sense to have one SC1 and the others SC4's. or something else I know the key looks the same as SC1 although I dunno how many pins...

What is my best bet to not create issues, use the 5 pin? SC1?

I would suggest trying the 5 pin first. It is possible to use a 5 pin key on a 6 pin lock... it just needs to be 'fixed'. Take a search around the forum, you'll find something. ;)
