Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

In this video we'll be removing, coating, and replacing an ignition cylinder in a 2009 Chevy Suburban. If you need this part or other parts for your vehicle, click the link in the description and head over to

We're gonna disconnect the battery. Gonna use a 10 millimeter wrench and we're gonna disconnect the negative post on the battery. Just loosen this up a little bit. And I can grab it, and wiggle it back and forth. I can take it and tuck it out of the way. Alright, take this off. Just grab it and pull.

Now we're gonna grab this cover. We're gonna have two fingers over here, pull down. Grab over here with the other hand and kind of slide it out. If you struggle taking this out or installing it, you can remove this. I'm just gonna move the steering wheel down, so, I'm gonna push on that lever. Make sure, be careful for your fingers and then slide it down like that.

And then you're gonna grab the top part. Two fingers, and grab over there, and slide that out. We're gonna use a blunt pick that we had modified, we cut it off. You can use a regular pick for this, also. We're gonna take my key, gonna turn it like I'm cranking the engine. Then, I'm gonna push this down here and that's gonna release it and then I can wiggle this out. And this will come out completely.

This is our old lock cylinder. This is our new lock cylinder from 1A Auto. It's gonna come with this and all the keys and all these springs, and the directions. As you can see, it's almost identical. Has the same lock mechanism right here, has the same key hole, same plastic, same lock to hold the cylinder in. Get yours at and you'll be ready to rock and roll.

Alright, first thing we want to do is set this up on a nice clean surface, so that we're gonna be able to see everything when we take it apart. We're gonna set up our bags over here, our springs, and our lubricant. We're gonna cut open the springs. Take those out.

And then we'll cut open these bags, we'll leave everything in the bags, like that. We're gonna take out the tumblers, one at a time. We're gonna write them down and when do that we are gonna put the new ones in, one at a time, and check it with the key.

So, to get these tumblers out, you can see the side that has kind of like a circle, right there. The opposite of this side, right there. So, that is the direction the tumbler is gonna come out. So, I need to flip it over. We're gonna push with a straight pick, down, and that's gonna pull the tumbler out. We can grab it, pull it out, and this ones very worn. See that, it looks like it says the number 3 on it, right there. So, we'll put that aside and we're gonna write down three for the first number. Then, we're gonna come over here, grab a spring. We're gonna stick this spring down in that round part of the slot. We're gonna grab a number three tumbler and push it in like that; on the first slot, I'm gonna push it down.

Then, as you can see, this little lock, that's what actually locks the cylinder. We're gonna take our key and were gonna try it and see if that goes down. Just like that, it went down.

And so, now we're gonna do that same thing, same procedure, with each one; one at a time. Push down, like that. Pull that tumbler out and that looks like a number one. And then, see how this side, the circle was on that? This one, we're gonna flip over and the circle's on this side. Stick that in and then we'll get out number one tumbler and push that down. We'll do the same, and check it, and that went all the way down.

So, repeat those steps for the rest of the tumblers. Now you can see that our key works. The lock goes down when I push in the key all the way. You can see all the tumblers moving when I pull it in and out. And now we're gonna take and put the grease all on here and then on the other side. And, it's ready to go back in.

We're gonna reinstall this lock cylinder. You wanna line this tab up, right here, this little keyway. You want to make sure the key's in there and you can turn it to the off position and pull it out. We're gonna reconnect our battery. Grab the negative cable and hook it back up.

Now, I'm gonna use my 10 millimeter wrench to tighten down the nut. Not too tight, you don't want to break the terminal. Tighten it and check it. Make sure it doesn't wiggle. Seems good. Before we put the covers back on, I reconnected the batter, I'm just gonna test it and make sure everything works and the vehicle starts and stuff. So, here we go and start the car. We want to check on the dash and make sure there's no theft light or anything. It looks like it's working properly.

Now we're gonna put this upper cover on. Gonna line this up with the rubber boot, over here. Try to get that on. Sometimes it a little tricky. Slide that in and slide the cover over here. Have it lined up and just push it down. That's good.

Now, we're gonna adjust our steering wheel up. Gonna slide the lower cover to the back and try to slide the boot onto the cover. There it goes, in the U. Slide the cover up and just click it in place. It's all locked in. We're gonna reinstall the steering column adjuster lever. Just push it in and you can adjust your steering wheel accordingly.
