            Answer This Question

            Thank you for your inquiry regarding this item from Prime-Line Products. This item comes with 2 keys. The key blank used for the lock is an Ilco 1098M B1 keyway. Please try a local locksmith. The keys from the OEM tend to be skinnier so have the locksmith check the width of their blank to compare,

                    Not secure at all.
                    A mail box key will open it. Very disappointed how poor the keyed lock is.
