How to Replace a Ford Focus Ignition Switchby Alibaster Smith
The ignition switch in a Ford Focus uses a simple ignition lock and switch mechanism that is secured to the steering column. The switch uses a chip that is coded inside the key, which allows the ignition to be unlocked so that you can start the vehicle. Unfortunately, the Ford Focus has a known faulty design that fails often because of bent tumblers inside the cylinder lock. When it happens, you won't be able to turn the key to remove the ignition switch. Fortunately, there is a way to replace the switch, even if you can't get the ignition key into the cylinder or turn the lock.
Draw an "X" on the cylinder with a marker to locate and mark the center of the cylinder lock.
Drill a 3/8-inch hole into the center of the "X," drilling down into the ignition switch about 1 inch.
Use a pick tool to fish out the lock bar from the ignition switch that prevents the ignition from turning.
Turn the ignition switch to the "Run" or "II" position with a flat-head screwdriver. With the lock bar removed, the ignition will now turn. You'll need to hold the key right up next to the ignition because of the coded PATS chip system inside the key. This chip allows the car to be started and the ignition lock from disengaging fully.
Push the punch pin into the hole directly underneath the ignition switch on the bottom of the steering column.
Pull the ignition switch out of the steering column.
Insert the ignition key into the new ignition switch, and turn the key to the "II" position.
Slide the ignition switch and cylinder into the steering column where you removed the old switch.
Turn the key to the "Off" position and remove the key.
