The Ford F-150 is a light-duty truck that allows you to haul or tow heavy loads but still use it as an everyday vehicle. Ford completely redesigned the F-150 in 2004 and only made slight changes to the 2007 models. A variety of bed sizes and cab configurations were available, and 2007 F-150s came with a full complement of convenience options, including the keyless entry system. Punching in a code into the driver's-door keypad allows you to unlock the doors without using a key. You can retrieve this code in one of three ways.
Open the glove compartment, and locate the packet that contains the original factory wallet card, which has the factory keyless entry code printed on it.
Open the hood. Locate the computer module mounted on the firewall. Locate the factory keyless entry code, imprinted on a label on the outside of the computer module.
Take your truck to your Ford dealer to find out the factory keyless entry number.
