You ever dig up some old piece of hardware, or inherit some old trunk of goods from a relative and you go to open it or start it up and you find out it's locked? And you don't have the key? Or you had the key and it broke inside the lock? Or, well, we're in space here, it could be a digital lock and the combination has long since been forgotten. Time makes fools of us all, but thankfully Altair Electronics employs Nanami, Aoba Systems Android and resident locksmith. Nanami has a very cheerful, gee-whiz sort of attitude about the world, often being like "oh gee, look at that!" just before she pops a busted lock on some old safe like it weren't nothing. When handling a job for a client she's always very privacy-minded, agreeing to pop a lock without opening a safe or a drawer or a lockbox to snoop at what's inside- that's the customer's little treat to discover. Nanami gets along with everyone, she is just remarkably likeable.
Nanami has spent a great deal of time practicing her craft- she doesn't have any innate abilities or programs like other Androids, and she doesn't have any kind of special sensory enhancements, she's just observant and intuitive in her understanding of locks and built her craft the same way any organic locksmith might. The truth is many locks are mostly security theater, and many of the locks that come through Altair's doors are trivial to pop, but the ones that are serious are really serious, and Nanami knows to approach them with care. She likes working with mechanical locks the most, since she can use her ears and her fingertips to have a conversation with the lock, listening to its clicks and the gentle vibration of its movements, but she can manage an electronic lock as well- those types are just looking for a particular signal, it takes a bit of sleuthing to figure out what it is and how to replicate it and you can pop them open easy as pie.
The trickiest of all types of lock to crack are Ganymedean organic locks, which are built out of special root-like plants which use interlocking spiral arms to form a seal that needs to be relaxed with a particular stimuli in order to open up. Ganymedean organic locks are a popular feature on safes meant to hold very valuable things, as they're highly resistant to attacks from digital hackers, Accra droids' data access abilities, Horizon droids with strong Job Cart combinations, Quasar droids with their excellent hearing and mechanically-adept Mercurians, all of which presenting problems for deep-space security manufacturers. Nanami doesn't rely on the innate features of her being, however, so she's pretty good at coaxing these difficult organic locks open the old-fashioned way. Wow! Look at that!
It goes without saying, but the more law-averse among Titan's residents always, always have a use for a good locksmith. Nanami receives the occasional offer to cut in on a job as their lockpick, but she often turns them down; she's not big on adventure and she's not interested in scary car chases or being shot at by angry security. If you happen to abscond with a locked box, however, and she can meet up with you safely, she's inclined to pay you a visit after hours and defeat a security feature for you, for a price. Like her legit business, she'll pop by, pop a lock and pop off without snooping about trying to see what's inside the lock, it's often better not to know!
You do need to have a good reputation for Nanami to trust you enough to lend her secret-menu services after hours. There's a lot of two-bit crooks looking to pop a personal safe lifted from some poor starfarer, and she's not about that. Bank jobs, corporate jobs, casino jobs, industrial jobs; there's circles of professionals who pluck from draconic hoards, thieves who maintain standards that align with the intentions of Altair Electronics' other staff members. Nanami's sweet but she's not naive, she knows exactly what her skillset is useful for and she'll only endeavor to help crooks of noble repute. You've got yourself a voice-sensitive safe from a Callistan prince's highrise suite or a bio-locked briefcase containing some sensitive bit of Quasar Galactic warp current research? Whoops! How'd that just pop open all by itself like that? Ha ha! You all stay out of trouble, I'll see you back at the shop sometime!
