To order IC Cores you need to specify the finish and the keyway. The cores come furnished with 2 keyblanks.
We stock the standard 6-pin commercial core, but you can also special-order the 7-pin version. These come from the factory with a 4 week lead time (nothing comes quickly from the factory).
You need to use a Control Key in order to insert or remove the Core. If you have other Cores already you can use the same Control Key. You only need to make sure the Cores and the Control Key are the same keyway type.
If you are ordering IC Cores for the first time, you will need to buy a separate Control Key. You can add that option above. We will make sure the Control Key matches the keyway you specify.
