Hi-tech doors?

[kalirion]

Finished the game, but still can't open any of those doors requiring "hi tech". The "hi-tech" gizmo which allowed me to pass through the mansion gates doesn't seem to be enough for some reason....

Talk with judy and she will ask you to buy some film, some steps more and you'll have what you need to open hi-tech doors.

Cool, thanks!

*Spoiler below* took this from the walkthrough


Once you’ve taken all the main evidence to Judy, talk to her again for a quest to buy her some film. So go to Harvey, buy film and take it back to Judy
Judy will reward you with a crayon.
Take the crayon to Ruby, who will give you a flower
Take the flower to the triplets in the playground. They will give you a donut
Take the donut to the thugs in the Crows’ hideout. They will give you a chain
Take the chain to John the museum archives guard. He gives you a handkerchief
Take the handkerchief to Jane in the café district. She will give you an apple
Take the apple to grandma at home. She gives you a scarf
Finally, take the scarf to Harvey and he gives you the pro thief kit, which allows you to access the security doors
