Can you program a Key fob to a 2005 Ford F-150 XL without any power lock buttons?

So my 2005 F150 XL is a two door without any power lock/unlock and window buttons. The windows are cranked, and to get in you must use a key. Even without the power lock buttons, would I still be able to program a key fob to the truck?

Does it even have an alarm? There's nothing else to control.

No. A key fob won't DO anything for your truck. You'll still need to use a key to lock/unlock the doors and start the engine.

No. There are no lock mechanism actuators or the wiring harness for them.
