Ford ignitions fail in a few mechanical ways. If the key suddenly spins in a full circle with no resistance, or if it binds and will not turn, the fault is usually in the column.
The broken housing tailpiece
On many 2000–2011 Focus, 2001–2012 Escape, and F-150 trucks, the cylinder sits in an aluminum housing. A small tailpiece on the back of that housing turns the electrical switch when you turn the key.
The cast tailpiece snaps. The key then spins freely and the car will not start, because the switch never moves. We fit a reinforced housing, move the original cylinder into it, and the key you already use still works the ignition.
When the cylinder binds
If the key will not turn at all, the wafers inside the cylinder are bent or worn. A heavy key ring bouncing in the lock does this over time. We pull the cylinder and replace the damaged wafers.
When the switch is the fault
If the key turns with normal spring pressure and the starter still does not engage, or the engine dies when you let go of the key, the electrical switch is the likely part. We check voltage at the switch harness before replacing it. Compare that with the ignition-switch symptom guide.
Housings, cylinders, and switches for the common Ford years ride on the truck, so the repair finishes where the car is parked. If the cylinder itself is the worn part, the choice between a rebuild and a new cylinder is the same one in our cylinder repair guide.
