Adjusting
Ash used the bolt cutters to open the lock that was attached to a metal chain.
The chain was wrapped around the metal door frame and once the lock was removed, she was able to remove it too.
She then proceeded to cut into the remaining obstacles until the door was able to be opened by her.
Ash went back to bring a lock of her own which she replaced with the old one.
The key was with her so it would only be possible for her to open it up unless someone tried to break in.
If it was forced open then that would serve as a means for her to realize that someone had entered.
it provided her with a way to enter and exit freely while not leaving it open for others to wander inside carelessly.
The only people who could enter would be someone who was a Balancer or Watcher who could see through the formation.
The metal security fencing that was high up and spiked at the top would provide additional security to keep others out.
