Ra used exactly those words. In one lecture he said: "We have lock people, we have key people, and we have lock and key people." You can check your own chart in a minute. Locks: 25, 46, 10, 15, 1, 2, 7 and 13. Keys until February 15, 2027: 37, 40, 9, 16, 61, 62, 32 and 42. Keys after that: 55, 59, 34, 20, 54, 53, 57 and 51. An activation in a lock gate makes you a lock person, one in a current key gate a key person, both a lock and key person. Ra carried the 25 without the 37 and said that meeting a 37 was an important relationship for him, because the key goes into the lock. He also called this temporary, a matter of where the wheel stands, so when the keys change in 2027 the key people change with them. None of it is a rank. Having no lock and no key exempts nobody, since the background reaches everyone, and carrying one makes nobody chosen. Whether a person is right for you is still decided by your Strategy and Authority, not by a list of gates.
This is not a fact, not medical advice and not a promise of healing. It is part of the cosmology Ra Uru Hu, who founded Human Design, left behind, and nobody knows exactly how it will unfold.
