How To Replace Ignition Cylinder Mazda MX-6

Learning how to replace the ignition cylinder on your Mazda MX-6 can save you time and money on professional repairs.  Many parts on a vehicle break down from wear and tear, and the ignition cylinder on your Mazda MX-6 is no exception.  If the ignition cylinder spins freely within its housing or if turning the key does nothing to crank the car, then it’s time for a replacement. 

What you’ll need:

  • Steering wheel puller
  • Ignition switch
  • Phillips head screwdriver
  • Flat head screwdriver
  • Dremel tool
  • Hammer
  • Chisel
  • Ratchet set
  1. Prepare for the replacement.  First, park the car and straighten out the steering wheel, and then disconnect the negative terminal on the battery to avoid accidental shock.  Also remove the air bag fuse in order to avoid accidental discharge and possible injury.
  2. Remove the steering wheel.  Remove the three 10mm bolts holding the airbag to the steering wheel.  Pull the airbag out, then disconnect the airbag, horn and cruise control.  Remove the plastic panels covering the steering column.
  3. Remove the ignition cylinder.  The cylinder itself bolts directly to the steering column, using a U-shaped bracket and two break-away bolts.  Remove any connectors linking the assembly to the column, then use the hammer and chisel to create a notch in the bolts.  If you choose, you can also drill out the bolts using a Dremel tool.  Afterwards, remove them with a flat head screwdriver and remove the assembly from place.
  4. Install the replacement cylinder.  Insert the new ignition cylinder in place, using the existing bracket and two new bolts of similar size to secure the assembly to the ignition column.  Replace the connectors and reassemble the plastic panels and airbag in reverse order.
