I have 2008 F-250 bought used and do not have keypad #

 

Go to local dealer and have them get the code. You may need to pay a small diagnostic charge. If the service manager is willing to work with you, they may do it for free. Ask them nicely and it might help lower the price. Or if you have some minor work done, ask them to get the code for you.

 

1st, look in owners manuel packet, if its still in glove box, there should be a plastic card, kinka like a credit card, that has keyless entry code on it.
Guessing that packet isn't still there or you would have gotten the code.

2nd, the 5 digit code is on the module which is usually located up under the dash on left side above the park brake pedal assy. you can see it by looking up under dash with flashlight.

3rd, If its not located there on your model, just call Ford Dealership and ask service dept where your keyless model is located.
