You can any combination of locks. Eg a Schlage BE469 and a FE599 or a pair it with a Yale YRD series or Kwikset 916 (avoid the 910/912). Yale and Schlage are great quality and lots of trim options.
They won’t auto synchronize but that’s the easy part, you can use something like CoRE to create a rule or something more sophisticated like this app: [RELEASE] Lock and Door Synchronizer, synchronize your locks with other locks, doors, switches/relays
If you’re using a Lock Management like LUM, you can assign actions to unlock multiple locks or lock multiple locks when a user code is used to lock or unlock one of the locks.
