Original TRW Data Systems Keypad--Same Model Used in Back to the Future (Ships fast and free from the USA!) You are purchasing a TRW Data Systems keypad. This is the same model that was used in the Back to the Future DeLorean time machine to enter the month, day, and year into the time circuits. It is, of course, not the same color as the one in the movie, but that's a small hurdle to overcome compared to actually finding this part for your BTTF time machine replica or prop collection. It's attached to a metal device that appears to just stamp the number "1" with a circle around it when a card or piece of paper is inserted. I have not powered up the unit, so I don't know if the lights work. I do not guarantee ANY functionality of this part, nor do I know the level of difficulty involved in removing the keypad from the metal mechanism. What you see is what you get. This item cannot be returned. Trackable and insured shipping within the US via USPS Priority Mail is FREE.
