Btw this is mostly a joke lol
Alright. First things first, I gotta establish the situation:
You are in the FNaF universe, and suddenly everything Fazbear Entertainment turns against you. The animatronics try killing everyone, the electronics become deadly, etc etc.
Robot uprising, just FNaF.
Hate to break it to you, buddy, but you gotta ditch the FazWatch. Older technology might be better, as they maybe won't be in on the uprising. However, older technology won't be as efficient.
Go to a smaller town. Believe it or not, likely, there won't be a pizzeria or anything huge electronics store there. However, people might follow in your footsteps, and that'll be a problem because robots and stuff might follow.
Have a light source, but use it sparingly. Flashlights are incredibly important, and so are lighters if you wanna be in style. Maybe use a camera or the laser gun thingy, as those are established to be somewhat effective against animatronics.
Get the homies. The animatronics are usually only shown to work against one or two people. However, the concept of an entire group is rare and can work effectively. But don't get separated unless necessary.
Get the thingy from the novels that make people invisible to animatronics. However, this might only work on older animatronic models cause the thingy was used in the late 1990s.
Don't give out ur info, the animatronics will use it against you. You should probably change your appearance regularly, or even wear masks in case you piss off a specific animatronic. If you must wear a mask, make it an animatronic one. Being in full cosplay might be beneficial.
If ever faced with having to defend directly against an animatronic, be very careful. A lighter is useful, but fire doesn't seem to be as effective against certain animatronics.
Don't try taking animatronics on directly if you must. Range seems to be effective against them, so guns are perfect, and maybe go for eyes as eyes seem to be a vital part of the newer animatronic models. Maybe even a pipebomb if you want them to go out with a bang. You should also go for the legs, but in Monty's case, they can still get around, albeit with much more difficulty. If you manage to take out an animatronic, tear it it immediately.
