first off... my truck didnt come w/ a keypad handle, i added it later. i had the plastic card in my manual, just plug and play and the code/handle worked flawlessly. second, when the truck is running, if you press 7/8 & 9/0 at the same time, the truck locks. just like if you punch in your 5 digit code, then hit the 3/4 button all the doors unlock.
Yours is under the dash. Kinda behind the e brake pedal. There is a white box with a 5 digit code on it. That is your keyless entry module and the keypad code.
