Ford is one of the more DIY-friendly brands for remote programming, but the transponder and push-to-start sides have limits. Here's how it works.
Onboard remote programming (two-key method)
Many turn-key Fords with PATS support an onboard remote procedure: with two already-programmed keys, cycle the ignition from Off to Run a set number of times within a few seconds to enter programming mode, then press a button on each fob to enroll it. With fewer than two keys, the remote (and the transponder) typically needs equipment.
Transponder & smart keys
Ford transponder keys (4D-63 80-bit, ID49) and push-to-start smart keys (FCC families such as M3N-A2C931426 / M3N-A3C054339 by model/year) generally require Ford IDS/FDRS or a capable aftermarket tool to add or reset — especially all-keys-lost. The HU101 (SA) keyway is common on the emergency blade.
Order the correct fob first

FAQ
Can I program a Ford key with only one key? The two-key onboard method won't work; you'll need a tool or locksmith.
Do Ford push-to-start keys program onboard? No — they require IDS/FDRS or an aftermarket programmer.
