I recently re-organized the ownership of some of my houses and have a messed up situation now. After transferring the houses with internal door keys, the new owner only gets a golden front door key. All of the previously working internal door keys don't work any more. Using the "Change Locks" option will also not create new internal keys.
meh nevermind I got it. The gold key I got wasn't just the front door key but a "Master Key" you can use on internal door to receive a new key for the internal door.
I just think it's confusing how you get all different keys nicely when you place and just the golden master when you trade or replace locks ....
