door locks

I HAVE A 1999 F350. IF THE TRUCK SITS FOR A COUPLE DAYS I AM NOT ABLE TO UNLOCK IT WITH THE FOB OR THE KEY. (KEY WILL NOT TURN) ONCE I GAIN ACCESS AND ONE OF THE DOORS HAS BEEN OPENED, THE FOB WORKS GOOD AND SO DOES THE KEY. THANKS FOR YOU HELP

so neither one of the doors work then say if you open the drivers door, then the passenger door works? And my question is how do you get into the truck if the locks dont work with the key or the fob

WHEN THIS HAPPENS I GET INTO THE TRUCK THROUGH THE REAR SLIDING GLASS WINDOW. I HAVE HAD TO SEND MY SON INSIDE TO UNLOCK THE TRUCK. WHEN I SAY THE FOB WILL NOT WORK A LONG WITH KEY IT IS LIKE SOMEONE HAS CHANGED THE LOCKS. ONCE INSIDE AFTER THE DOME LIGHT COMES ON EVERYTHING WORKS AGAIN.

If in fact the key does NOT open the doors, have you tried it on the tailgate? If it also doesn't work there, I would suspect the ignition has been replaced. Does the key have notches from front to back, or does the key look like it only has notches toward the front? There is like 8-10 positions on the key and the ignition uses like 4 and the locks use the other 4. (pulling all this from memory, so might be off by a few positions. So I believe you have a couple things going on here. Good news is you can get your keys re-cut (or replaced) to reflect the ignition and door locks.

Welcome to FTE, lots of great guys here. Just an FYI, some board members may take posts in ALL CAPS, as shouting.... not sayin, just sayin

Is the truck new to you or have you owned it for awhile, if so how long,? Trying to rule out the new ignition and lock change. There isn't a whole lot of magic with the manual key opening of the door. Is it cold where you are and did all this start when it got cold? Are your batteries in good shape? When you push the unlock button on the FOB do you here the door lock mechanism trying to move or operate? Can you see the locking tab on the top of the door sill moving when attempting to unlock with the FOB. Have you searched the Superduty forums for posts like yours?
