As Liz is transferring the computer files, a wide shot shows the transfer status bar as almost completed. Subsequent close-ups show much lower percentages of completion.
Liz does a "Hollywood hot wire" on a 90's model Pontiac Bonneville at the plant. She is shown starting it by connecting a few wires conveniently pulled from under the dash. There are at least four fails for this: First, the wires needed to do so are in the ignition column, not under the center of the dash as was shown. Second, unless she did this regularly or had a wiring diagram, she would not know which wires to connect. Third, this vintage GM car had and anti-theft device that require a key with a certain value resistor to enable the ignition. While she could crank the engine, it either would not start or would briefly start and then stop. Finally, these cars have a steering wheel lock that would prevent the car from being steered even if the engine ran.
When Red and Liz are at the plant's main entrance, it has a typical numeric keypad. Liz states that the combination could be one of thousands.
Red blows some sand on the keypad and sand sticks to all keys save four of them. Red then states that there are now only 24 (or 4 factorial) combinations. This is true ONLY if the combination must be comprised of unique digits (example: 2341).
If the digits of the combination may be repeated, which is most likely the case (example: 4428), then there are 4^4 or 256 possible combinations. This also assumes there were only 4 numbers used. The possible combinations for 5^5 would be 3,125 or 46,656 for 6^6. If they could try 12 combinations per minute (5 seconds per attempt), 256 could take up to 21 minutes, while 46,656 could take up to 3,888 minutes or 65 hours or 2.7 days.

When Special Agent Navabi confronts Eli Matchett in the cornfield and steps on his wrist, there is the sound of a pistol being cocked just before Navabi points her weapon at Matchett. But Navabi is carrying a Glock, which is a striker-fired pistol with no external hammer; once a Glock has been charged (by racking the slide to chamber a round) the pistol is ready to fire and there is no further sound.
When the truck makes a quick turn in the cornfield while being chased, it makes the sound of tires screeching on pavement, yet it's on a dirt road.
