Look for the white model number/serial r sticker on the back or bottom of the toolbox. Visit the website for Sears and enter in the model number of the toolbox. Order the lock(s) that match your toolbox.
Use a drill and drill out the rivets until you free the lock from the toolbox frame.
Open the toolbox and empty all cabinets, drawers and containers.
Position the new lock over the place where the old lock was attached. Affix the lock with screws and screw them in with the drill. Add washers to the back of the screws to secure them on tightly. Repeat this step for each lock on the toolbox.
Things You Will Need
- If you can't find the Craftsman serial number for the toolbox, purchase a lock set that has three locks from a hardware store.
