How Do I Remove The Ignition Key Cylinder From A 1989 Ford Probe?

Disconnect the negative battery cable. remove the steering column covers. disconnect the electrical connector from the ignition switch. remove the screw retaining the switch to the steering column. remove the lower instrument panel cover & lower the steering column. disconnect the shift interlock cable from the ignition lock housing.The lock assembly is clamped to the steering column by 2 shear-head bolts, drill the heads off each bolt & remove the bracket. remove the steering column lock assembly from the steering column. mount the lock assembly in a vice & drill out the 4 pins holding the lock cylinder to the housing. Place the new cylinder in position without the key inserted & drive in 4 new pins.Mount the lock assembly on the steering column,install the bracket & 2 new shear-head bolts. tighten the shear-head bolts securely but don't break the heads off at this time.  Insert the key & check the lock cylinder & steering column lock for proper operation. when you are satisfied they are working properly tighten the shear-head bolts until the heads shear off. the remainder of the installation is the reverse of the removal. I hope that helps you!
