There is an older Steelcase FR series. The lock core installed in this furniture cannot be removed even though they are marked FR. The cut keys are the exact same, so a key ordered from us will work just fine.
You can tell right away its the older brand because the actual lock face is about the size of a quarter. The FR lock cores that can be removed and are currently being produced have a lock face that's about the size of a dime and has a small dimple on the front. There is another series of dime sized core that does not have an dimple and those are also non-removable.
