HINT: After key ID erasure, any remaining keys that are not reregistered at this time cannot be used. Therefore, immediately after key ID erasure, be sure to reregister all available remaining keys. |
Customer must bring at least 1 key |
1. Using remaining key, clear all registered keys except one (key ID erasure) |
