Query: Buy this BEFORE you need it!

I purchased this locking key storage box to hang on the underneath of our camper. I WISH I would have thought of putting spare keys in something like this BEFORE I had to pay a $60 locksmith charge to UNLOCK our camper .......... who knew the older campers lock up so tight and are break-in resistant! So, no more locksmith charges for us! Even IF you leave the keys inside like I did ...... It's tough and easy to set your own combination.
