To remove a barrel lock without a key, you can try the following steps:

1. Place the short end of the tension wrench into the lock as far as it will go.
2. Turn it in the direction that you normally turn your key to open the door.
3. Stick your pick into the lock while keeping your tension wrench turned in the same direction.
4. Rake the pick up and down and back and forth.
5. Twist the tension wrench in the correct direction, and the lock should spring open.

Another method is drilling out a barrel lock which should take just a few minutes. Place a piece of masking tape over the lock. Drill into the lock at medium speed for approximately 3/4 inch. Continue drilling at a slow speed until you feel the drill bit catch the latch bar, which will pop open the lock.

You can also use a lock pick to remove your barrel lock without a key. First, you need to be sure that you have chosen a pick with the right number of needles in comparison to the number of pins on your lock. Use a tightening bolt on the side of the lock pick. After loosening the bolt line pick up with the lock.

I hope this helps!
