This is Part 5 of the Murder of the President brainteaser/riddle series. If you have not already, check out the answers for Murder of the President - Part 1 posted by Nit, Murder of the President - Part 2 and Murder of the President - Part 3 both posted by Joe Z., and Murder of the President - Part 4 posted by el jefe. Each part will give you a clue and you must solve it. This part will have several clues. Use all knowledge you have of cryptography, ciphers, past puzzles, etc. You should also use Google. This case is meant to take place in the present day, so all politicians, celebrities, places, etc. are who they are now. Please post your answers in spoiler tags.
Here's the riddle:
You arrive at the London NYC Hotel at 2:26 a.m. You've already called the staff at the hotel to let them know you were coming. On the way up, you were beginning to hear reports that the President was murdered. You head up to room 118. You look around for a bit until you find a box under the covers. On top of the box is a note.
You check out the padlock. It is a one 5 digit code. Under the box there is another note.
After you figure out this code, you open up the box and find, of course, 6 coded notes. Some notes are typed, others are handwritten. (Italics will indiacte handwritten and bold will indicate typed)
Here are the notes

What is the code to get into the box? What do all the notes mean?
The messages are coded using the method and seed answered by el jefe. The sequence of numbers is continuous (it doesn't restart for each message). Also, you must add one to every zero in the sequence
Note: I will be posting Part 6 (the final part) in one to two days. I will select the correct answer for Part 5 before, but I will post the answer for Part 5 if no one gets it
