A Ford F-Series truck owner can typically find the keyless entry code for his F-150 or F250 in the original owner's manual. If the manual is not available, the code is written inside the passenger-side interior panel.
The owner can also look behind the radio, which may require disassembling of the dash. The five-digit keyless entry code is typically printed in white letters. In some vehicles, the number is printed behind the electronics stored inside the passenger-side interior panel. If these methods are not effective, an authorized Ford dealer can assist in locating the code. The keyless entry code allows owners to reprogram the door keypad.
