What should I do if I lose the key to a filing cabinet?

A few options: first, check if the manufacturer lists a key number on the lock cylinder — most commercial filing cabinet locks have a 4-digit key code stamped near the lock or on the original key. With that code, you can order a replacement key from a locksmith or directly from the manufacturer. If you don't have the key code, a locksmith can often pick a filing cabinet lock in minutes and cut you a new key. As a last resort, replacement lock cylinders are sold by most office furniture suppliers for $10–25 and can be installed with a screwdriver. Forcing the lock or drilling it should only be a last resort. FindOfficeFurniture.com — call 888-719-4960 for assistance with product support.
