Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to replace a worn out lock cylinder. If you ever have any issues with your car, the key doesn't seem to work, it doesn't turn any way or it turns difficultly, you want to suspect your lock cylinder. You'll need a new ignition lock cylinder from 1A Auto, T25 Torx driver, a Phillips head screwdriver, a pick and a 10mm socket and ratchet.

Start out by disconnecting the negative battery cable. Using a 10mm wrench or a socket and ratchet, loosen up the bolt and remove the cable. Just for ease, put your steering wheel up and then there are two screws, they're either 7mm or T25 Torx screws. Remove those two screws and then you can pull your panel, there, down. Underneath the steering wheel, you'll find another T25 Torx screw. Remove that. Now you can pull down on that panel and it just snaps together in a couple of different places. Pull carefully, pull straight down, and then pull it out over the turn signal and steering column tilt lever and then pull up and off on the upper panel. You have to pull it over to get it by the lock cylinder and then up and off.

Take a small flat blade screwdriver, disconnect the electrical connection at the top, insert your key, turn it to the on position, and, then with a small awl, there's a little button or a pull on top, press down in there, you'll press a button and the lock cylinder comes out.

The old lock cylinder is on the bottom. The new one from 1A Auto and the new one has to be put together and keyed to accept your key. Now you're going to put a little white grease on each side. This is the old lock cylinder. You're going to put some white grease on each side where the tumblers are and that will actually help to keep them in place when you take the locks off. Here, we're going to remove the retainers, using a small sharp awl. You can see that the white grease does it job of keeping those tumblers in place. Now, you're very carefully going to use your awl to start on one side and take out the first tumbler. We have a little piece of paper with a diagram or just the key on it and put each tumbler on it. We're going to go to the next side, take the first one out, closest to where the key goes in, put it on the paper and just keep repeating that, taking them out in order.

You can see that we've updated our instruction sheet and you can see some cross outs. Basically there's a first style and a second style on these lock cylinders and the cylinder we sell replaces both styles. If you're replacing a first style, you actually omit a couple of the tumblers and that's what the paper is telling us. It's telling us that we put the first one in. It's telling us that we omit the second one. For the third one, there wasn't one and after that we put all the tumblers in as they are. Now each tumbler has a small number on it.

Now here, Don is opening up part of the packet. These are the springs. Before you put each tumbler in, you put a spring in first. I didn't quite get this shot but he's just putting a spring in the first slot. This is an old style, our car has an old style and we're putting in the new style so we omit the first one and the second tumbler has a small four on it so we grab a four from our new kit. You insert that into the lock cylinder and the tumblers and the cylinder are actually such a way that you can put them in the wrong order but you can't put them in the wrong side. Don just figures out the correct side. You put the spring in first and then you put the tumbler in on top of the spring. Can you move down a little bit. Come closer to this way. Yeah. We skip two. Now he's doing the next one, he puts the spring down in, checks the number on the tumbler, gets one from the kit and inserts it. Like I said before, we have an old style cylinder on the car and our replacement is a new style so you omit the first one and then the third one there wasn't one in the original so you just keep going right down, matching up the tumblers and putting them back in. Since we're placing our old style lock cylinder with a new lock cylinder, you'll notice that there are no brass retainers anymore. You just put the lock tumblers in place and that's it.

That's with the key. You can see that key way is up. Put the key in, and the key way goes down. Put some grease on the cylinder to lubricate it, work it down into the tumblers. There's a groove in the lock cylinder there, make sure you line it up with the groove on that lock cylinder, put it in, turn it backwards and it's in place. Reconnect your electrical connection and you can test fire the vehicle and then put your trim back together. Once you get the trim back on, you put those bolts back in place and reconnect your battery.
