Both Yale superior and Yale platinum keys come with a card that shows three levels of codes. A, B and C for Yale superior and D, E and F for Yale platinum.
If you ever lose your Yale superior key card or Yale platinum key card, you can send your key to a key-cutter so they can help you decode them. Costs for this kind of service can go from around £13 on average to upwards of £22.
There are online and physical key-cutting businesses that offer key decoding services. Going to a key-cutter with a physical store may be a more efficient route as they can give you back your decoded key in just a matter of minutes.
