How To Mustang Ignition Lock Cylinder (79-93)

The ignition lock cylinder is the cylindrical tumbler and key that is used to power on and start your Mustang. Most ignition lock cylinders operate in different positions when the key is turned. The first turn usually unlocks the steering wheel, the second and third turns power on accessories and the vehicle's PCM if equipped, and the last turn cranks the engine.

The ignition lock cylinder is a mechanical component and has no bearing on electrical distribution other than when it actuates the ignition switch. With that being, if you are experiencing electrical issues or no-start concerns, I would take a look at the ignition switch and its associated connector instead.

5.0Resto currently offers their high quality replacement ignition cylinders in either a matte black or chrome finish. They feature a new wire and plug and of course will come with two pre-cut keys specific to that particular lock cylinder. These replacement lock cylinders are the perfect solution to a damaged or worn factory lock cylinder and for someone that has a car and is missing keys.
Installation is very easy ninety-nine percent of the time. If for some reason the key will not fully seat inside of the lock cylinder, a few extra steps will be needed. No worries though, we have those steps covered HERE!

Tools Needed:

  • Screwdriver

Installation Instructions

  1. To the begin the install, go ahead and disconnect the negative battery cable.
    Moving to the inside of the vehicle, loosen and remove the retaining screws that secure the upper and lower column trim pieces.
    Once the screws are removed, go ahead and separate the trim pieces and set them aside.



  2. Follow the ignition cylinder wire and disconnect the electrical connection.
    Insert the key and turn the ignition cylinder all the way to the "on" position.
    Find the small pin located on the underside of the ignition cylinder housing.



  3. Push the pin with a small Phillip's head screwdriver.
    While pushing the pin, pull out on the cylinder to free it from the housing.
    Take your new cylinder, insert the key and turn it to the "on" position as well.



  4. Align the ignition cylinder with the housing and slide it into place.
    To fully seat the new ignition cylinder, turn the key to the "off" position and then press up on the key release button to remove the key from the cylinder.
    The new cylinder is now locked into place.
    Reconnect the electrical connection and then reinstall the column trim pieces.



  5. Reconnect the negative battery cable, test for operation and you're all finished.


Installation is very easy guys and should take you no more than fifteen minutes from start to finish; that's of course if you don't have to go to the extreme to remove the old ignition cylinder.
