This is pretty much impossible based on the security technology incorporated into both the keyfob and the receiver in modern cars for one keyfob to reliably be able to unlock/disarm multiple different vehicles. I believe you can actually lock out your own keyfob so that it won't even work on your own car if you push the button enough times when you are out-of-range of your car, because it becomes de-synced with the cars receiver after you push it too many times without the receiver responding. If this happens, you need to put the key back into the car and perform a resync operation to get the keyfob synced back up with the car's receiver.
In order for this to work, the keyfob would need to be hacked/reprogrammed to do some sort of sequentially iterative key-code generation procedure and go through all of the possible combinations of different transmitter codes that exist for the manufacturer(in this case, Nissan). There are literally billions of these codes, and it would take forever and use a decent amount of battery power and and a ton of computing power to iterate through and broadcast all of them in a timely fashion... neither of which a standard keyfob board or battery is equipped to handle unless you had a heavily modified key-fob board and pushed the unlock button and let the iterative algorithm run continuously for hours/days. If you did that, then maybe you could get a hit on a few cars here and there in a huge parking lot with some luck.

Wow im an idiot? uhm thanks, Il make the video as soon as my girlfriend gets home from her parents house. I also figured out that it only works on certain cars, It wont work on another g35, but it does work on half of the altimas ive tried and 2 maximas (one being my neighbors), AND to show im not lying, how would you like me to record this video?
