1. Change the letters in EVA to numbers:
E = 5th letter in alphabet = 5
V = 22nd letter in alphabet = 22
A = 1st letter in alphabet = 1
EVA-01 = 5221-01 = 5220.
The code seems to be wrong in this level. The answer is actually 5200.
Press the keypad and enter 5200.
2. Proceed to 100 Doors Parallel Worlds Level 87!
