I bought the truck used. It has the outside key pad. I tried following the instructions in the manual to reset it using the code but that didn't work. Is there a trick to this?
If you are trying set the code to your own number. You have to be precise and quik. If it dont work. might be damaged. Remember the factory code will always work also. Also if you disconect the battery, it will erase your personal code.
Not sure what you mean when you say "reset it." If you are trying to erase any user-made codes, then resetting is the right option. Like other said, the factory default code cannot be changed.
If the previous owner has too many personal codes you canot add another. Disconect the battery a few minutes. Then the only code left is the factory default.
