After all, even a physical lock is just a combination lock. The combination is just 'encoded' in a metal strip. Or in the above case, with magnets. And it's still possible to copy the key by reading it.
Better to use a digital key with asymmetric encryption. Using that you can prove you have a private key without actually giving up the information needed to fabricate a copy.
