The ignition switch on your Ford F250 may need to be replaced if you are having trouble starting your truck. The ignition switch sends a signal to the starter motor which, in turn, starts the truck. When this switch fails, you will need to buy a replacement switch from Ford--many newer models of the F250 use a transponder key that requires a special ignition switch. Your key may also need to be reprogrammed. If your F250 does not use a transponder key, you can probably find a replacement switch at most auto parts stores.
Things You'll Need
- 1/8-inch punch pin
- Flat tip screwdriver
Place the key into the ignition and turn the key to the "II" position. If you cannot get the key to turn because the pins in the tumbler assembly have seized, skip this step.
Push the punch pin into the access hole directly under the ignition switch assembly.
Pull the ignition switch out of the steering column with the ignition key. If you could not get the key to turn in Step 1, pry the ignition switch assembly out of the steering column with the flat tip screwdriver while maintaining pressure on the punch pin.
Turn the new key in the new ignition to the "II" position and slide the key into the steering column until it snaps into place. Then turn the key to the "off" position.
