Ignition Lock Cylinder
Since it doesn't move all the time and it isn't situated in a place that's prone to dirt and other outside elements, the ignition lock cylinder rarely gets damaged. But over time, the small integral components of the cylinder can wear out and eventually stick. If after checking, you find out that the ignition lock cylinder problems you're experiencing suggest that you have your stock cylinder replaced, do this the earliest time possible.
If you cringe on the thought of replacing the cylinder because you know how much the ignition lock cylinder replacement cost will be, then consider doing the job all by yourself. Here's a step-by-step installation guide to help you out:
What you'll need:
- Wrench set
- Lock plate tool
- Screwdriver set
- Steering wheel puller
- 1/2-inch drive socket set
- Vehicle's service manual
- New ignition lock cylinder
Step 1: Disconnect the battery's negative terminal.
To prevent accidental deployment of the airbag while you're doing this DIY task, disconnect first the battery's negative cable. Wait for 15 minutes. This will give the capacitors in the air bag system enough time to discharge and switch the system off.
Step 2: Remove the horn pad.
Using the appropriate screwdriver, loosen and remove the retaining screws that secure the horn pad to the steering wheel. Disconnect the horn contact as well as the yellow air bag connector.
Step 3: Take out the steering wheel.
To do this, you have to remove first the nut that secures the steering wheel in place using the correct socket and drive ratchet. Get the puller and attach it to the steering wheel. Tighten the puller's center bolt until it causes the steering wheel to pop free.
Step 4: Remove the lock plate.
The lock plate is usually positioned behind the steering wheel and you'll need a lock plate tool to remove it properly. Screw the tool to the steering shaft and tighten the tool's jam nut until you've pressed the spring-loaded plate far enough to let you remove the retaining plate in the steering column using a small screwdriver. Loosen the tool so the plate can move up the steering shaft and, finally, take the tool out and detach the lock plate from the steering shaft.
Step 5: Detach the ignition lock cylinder from the steering column.
To remove the cylinder, you first have to deal with the white plastic turn-signal cam positioned behind the lock plate. Loosen and remove the screws that secure this cam to the steering column and pull it up to reveal the retaining screw of the lock cylinder. Some models have a release button instead of a retaining screw.
You need to unbolt the retaining screw or press the release button until you can freely take the lock cylinder out.
Step 6: Install the new ignition lock cylinder.
Position the new lock cylinder in place and re-place the retaining screw. To lock the new cylinder into place, turn the key to the lock position and take out the key.
Step 7: Re-install everything you've removed to access the ignition lock cylinder.
Put the turn signal cam back into place along with its original screw. Carefully install the lock plate into its place and compress the spring-loaded plate using the lock plate tool. Install the steering wheel and shaft and secure them in place using the ratchet.
Reconnect the electrical connectors of the horn pad and screw it in place. Hook up the battery terminal. Check by starting the engine.
