Currently the doors only has 2 door types : Key locked and Code locked. (Note I am only discussing doors here, not safes.)
They have their own variety of skins and quirks between them but their locking method is usually just the same as others. Not only is this very limited but it often makes many areas, especially upper end areas like city hall, quite easy to consistently break into without much resource usage or consideration beyond just not being seen.
There is also an issue with the Keypad doors, you can lockpick the doors without the pad code and it'll unlock the door without an issue.
Immediate suggestion : Remove the ability to lockpick keypad doors OR make them extremely long to pick. (Like triple the strength)
Door suggestions : More security types for doors, here's a couple easy spitballs.
Deadlocks : Most people usually have them if they care about security beyond a door knob. Some people even get extra locks that require a second key, which would force a second lockpick.
Complicated Locks : This would mainly be for the case of the Lockpick Kit becoming an item and not just giving 30 lockpicks, these locks would be unpickable through normal means and require a kit, much like the codebreaker is meant to brute-force code locks, this would be your method for these.
Keycard doors : No code breaking or key picking with this, hope you're observant of the items around you or able to snag it off someone. Probably mainly for stuff like factories, upper businesses or city hall.
One-way doors : One side doesn't have a doorknob, this would mainly be used on diners or other eating places, primarily for staff to take trash out to a dumpster. It's meant to prevent people from just opening the back door and walking in as there isn't a knob to open from that side.
Computer operated : A locked electric door that is operated from a security room's computer. I'm not sure where you'd put something like this in the generation but it could have a use for something.
