Lock Cores
Replacement lock cores. The core is the cylinder inside a lock that holds the pins your key turns. Fitting a new one changes which key works, without replacing the lock body or the furniture around it.
Cores are not interchangeable. The housing, the finish and the cam or tailpiece on the back all have to match what you are taking out. Pull the old core and compare it before you order.
We stock cores for office furniture, RV compartments, tool storage and cabinet locks. We carry brand-specific cores for Herman Miller, Wesko and other furniture makers. Where core, housing and keys come together, they are sold as lock core kits. Keys for a new core are cut to code, or cut in-house from a key blank.
Can't find what you need? Contact us by phone, email or live chat. Our US-based customer service team is here to help.
