front door lock broke,,NOW WHAT???{{{{UPDATE}}}}}}

Is one of you windows an emergency exit?? If so, maybe you can get a hand or tool inside to release it. If not, it might be cheaper to break a window to get inside rather than the amount of damage to the door. Another possibility is drilling holes, then using a hacksaw blade in a sabersaw. If you are reasonable sure where it is, maybe a smaller hole through the outside to allow a screwdrive to push the latch back. Wish you luck!
