A safe-deposit box in a bank can be opened:

Question

Quizplus · Accepted Answer

Both the banker and the account holder's keys are required to open a safe-deposit box in a bank. This ensures that only the account holder and authorized bank personnel can access the contents of the box. The keys are often different in shape and size to prevent unauthorized duplication. Using only one key, whether it is the banker's or the account holder's, would not provide sufficient security for the contents of the safe-deposit box. Neither insurance companies nor their keys are typically involved in the opening of a safe-deposit box.
