Cal. Fin. Code § 1647

The provisions of this article do not preclude any other remedy by action or otherwise now or hereafter existing for the enforcement of the claims of a bank against the person in whose name the safe-deposit box stood or stands, or in whose name the safekeeping or storage receipt was issued, nor bar the right of a bank to so recover, at its option, either the entire amount of the debt due to it without recourse to sale of the property, if any, or so much of the debt due to it as shall not have been paid by the proceeds of the sale of all or any portion of the property deposited with it.
