If you want to open a padlock and don’t have the key, you can almost certainly break it open with 2 big wrenches.
I only had 1 opportunity to try that yet, when removing a 20 year old lock some stupid kid left on my stuff and then forgot where I put the key, but man did it feel empowering.
You can practice this trick at any romantic bridge. Do you really think whoever etched their initials on the lock is still together and would notice? Please
