If you are ordering several locks which all open with their own key, then order 'Keyed to Differ'. Each lock will be supplied with 2 keys.
If you are ordering several locks which all open with the same key, then order 'Keyed Alike'. Your order will be supplied with 2 keys. Additional keys can be ordered.
If you already have Flexcore locks and would like more locks which can be opened with the same key, then order 'Keyed to Existing Lock'. This order will not be supplied with any keys, but keys can be ordered separately.
Additional keys ordered with locks are reduced in price from the normal price.
