They're NLA for the W126 as well. You can still get the key cut by VIN, but you can't get the lock cylinder anymore. They do have a generic "Mechanic's" lock cylinder with key, but it is not VIN matched, comes with only 1 key which they will not duplicate, and costs ~$140 for what's essentially a $30 Meyle lock.
