What ever you do, don't do the driver door. There is a 99 to 100% chance the lock will break and then the door will only open from the inside. That's why AAA will not be responsible for the outcome of slim jiming your doors. Do the passenger door on a two-door or the driver rear on a four-door. Take it from someone who has been there more than once before they learned.
You arrange the sliders on the door in the same pattern as the disks on the ground. First slider (from the left): move to the bottom. Second slider: move to the top. Third slider: move slightly under the top one... between top and middle. if the door isn't open already at this point, then Fourth slider, move under slider 3. Once they are in the same formation as the floor, the elevator doors will open.
