You can pick standard Yale style pin tumbler locks with a penknife nail file and a paperclip.
Insert the nail file into the lock and apply turning pressure as if you are turning the key, then fiddle with the pins with the folded out paperclip. One by one the pins pop into place and the lock will open.
You can do this with practice in under 30 seconds. If you only have a Yale lock on your front door, fit a good quality lock instead, or at least a good secondary. If you are at home and only have a Yale style lock on your front door, then always lock the door and leave the key quarter turned in the lock.
This prevents anyone from trying to enter from the other direction. It also makes it easy to escape from the locked house in case of a fire if the keys are in the door already.
