The 2004 F-150 FX4 requires the steering wheel to be removed, see youtube for help. There is a Transponder that needs to be removed to slide the Cylinder Lock assembly out using an awl to release the locking pin. The transponder reads the security code on the chip in your Key. Make sure to remove positive and negative battery terminals and remove fuse #19(air bag fuse). There is youtube to help with airbag removal, 1AAuto(turn signal replacement video). Then make sure you study the cylinder rekeying installation in the Dorman 924-717 kit instructions, also see youtube for rekeying instructions for the Pins and Springs. WORKs great saved $65 over the Ford version.
