This key is for the tubular or barrel style lock that is used on KOBALT tool boxes and tool chests. Your lock will only have the numerical code on it while the original key will have that same number but with an HS prefix. This is used on current Kobalt products and will not work on other brands as far as we know. Your key will arrive precut and ready to work in the lock. SAVE 15%. Just order 2 keys or more and then use the code LOSTAKEY in the discount code redemption box during checkout.
