So as you make locks, why dont magnetic keys that repel pins get used to make it harder to pick a lock? After all how would lock picking lawyer measure the mag

  The pins would have to be fairly far apart to not be affected by each others' magnets I think. Also, this would be pretty easy to 'brute force' with a special key with some electromagnet coils. With physical tumblers this is much harder to do, work all the small moving parts (though I believe such tools are now also possible) 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.
