Banks literally do have to perform money laundering checks on deposit boxes.
Standard rental agreements explicitly state that the bank does not retain a key and is unable to open the box (without destroying the lock) in the event that you lose yours.
For example: https://www.bankofamerica.com/content/documents/deposits/saf...
"The bank does not retain duplicate keys for any rented box".
To my knowledge, my bank cannot access my safe deposit box without my key or without drilling and replacing the lock my key opens.
Am I mistaken about this?
