How to Remove the Ignition Lock Cylinder on a 1993 Mazda MX-5

Written by tim petruccio | 13/05/2017

Mazda introduced the Miata for the 1990 model year, in the summer of 1989. The 1993 Mazda Miata was equipped with a 1.6-litre, dual-overhead-cam, fuel-injected, in-line 4-cylinder engine. The 1993 Miata produced up to 116-horspower and 100 foot-pounds of torque. The ignition system on the 1993 Miata was a coil ignition. The ignition lock cylinder has tumblers inside, just like a normal key lock. Over time, these tumblers can wear down, making it impossible to start the vehicle. Removing and replacing the ignition lock cylinder is the only option when this occurs.

Open the bonnet of the Miata. Remove the negative battery cable from the battery. Use a 1/4-inch drive ratchet and socket to loosen the cable tie down nut. Remove the cable from the battery by hand.

Sit in or next to the driver's seat of the Miata. Remove the two fastener screws from the bottom of the steering column using a Phillips screwdriver. Separate into two pieces the steering column plastic collar, which is held together by snapping tabs that can easily be separated with a flathead screwdriver.

Remove the lockdown bolts from the lock cylinder, using a 1/4-inch drive ratchet. Pull the lock cylinder up and out of the recessed steering column.

Pull the two electrical connectors off the end of the ignition cylinder. They should slide off with a little force. Remove the lock cylinder from the MX-5.
