One of the best-known ways to unlock a deadbolt without a key is by using two bobby pins. Start by inserting the closed "looped" side of one bobby pin into the bottom portion of the lock. Use the second bobby pin, broken in half, toward the top of the lock and move it back and forth. This motion should set the pins and cause the deadbolt to unlock. If this doesn't happen within a couple of minutes, you should remove the first bobby pin and reinsert it before trying further.
If you do not have bobby pins on hand, you can use any small, thin piece of metal. You could try using a heavy duty paper clip, for example.
"Lock bumping" has been used to open deadbolts without a key for years. You can buy a bump key set from various locations including Lowe's and Walmart. Simply enter the bump key into the deadbolt lock and use a screwdriver or other sturdy-ended tool to hit the end of the key toward the door. The force should cause the key to turn, thus unlocking the door.
