1995 96 97 98 99 GM Truck Ignition Lock Cylinder Removal (Chevy Cadillac & GMC)

guys I'm going to show in a video today it's a pretty short one on how to remove

the ignition lock cylinder from the ah from the steering housing here on this

98 Chevrolet Cheyenne ah you start with removing this lower plastic shroud this

tilt lever just snaps out there's a little detent here that holds it in

place it just snaps in and out and then a T25 Torx theres 2 T25 Torx screws one here

and another one right here in the back

once you get these two T25s out this guy'll start to come down in the back

there are two little hooks just like this that loop around a stud that's on

the top part you push in push towards the back then push it and see there's

that one make sure you do it carefully you don't want to break these this

plastic can get brittle when it's aged I'm going to do the one on the other

side now and now we have the lower shroud housing off the next step is to get the

top piece of the plastic off that is held in place by two E5 Torx head bolts

there's one here take this first E5 off and you might have to hold this little

shaft here this plastic shaft it might be moving if it's separated from the top

of the plastic housing with as old as this plastic is on these vehicles and

then the other one is directly up underneath here and I'm going to have to

um pause the camera I'll take that one off I'll give you a shot of that in just a

second okay guys here's that other a E5 bolt I was talking about it's right here

I'll move back here give you a perspective right underneath so adjacent to

the side of the ignition switch so I'll take this guy out and we'll come back

show removing the top all right now that we've got those two E5 bolts off go get

the tilt lever that you took out before snap it back in because we're going to

need to lower the how the steering column of course if you don't have tilt

you know if you're worried about this take this guy out again you're going to

need some type of a spudging tool or a prying tool made of plastic so you

don't damage anything because what we're going to be doing is we're going to be

separating the outer part of the steering wheel soft plastic and prying

up the hard plastic from the top shroud

go nice and slow to get it out all the way on both sides okay once that's done

we're going to take our key put it in just enough press the brake and lower

the uh gearshift lever all the way down so that we can then work this guy out the

rest of the way okay now next thing we're going to have to do is go down and

disconnect the negative battery cable if you haven't done it already because in

order to remove the lock cylinder we're going to have to advance it to the start

position so let me pause do that come back and pop it out all right now I'm

going to put the gearshift lever back into park reach in here remove my key

and finish removing the top housing now you know that I cheated a little bit with

this because I've already in the past not this piece out because it was

difficult to get off wrong when you have to service this kind of a thing and I

just leave it on the back of the ignition lock cylinder like a washer so

you can either do what I did there you know you can get it up part way and just

give it a sharp whack it's usually enough to knock this thin ABS blas

plastic off here the other thing you can do though is if

you have a ninety degree shaped um pick or punch or something of that nature that

you can slip under here before you fully remove this you know and get it under

there and into this little hole and push it down that will work too

you're going to have to do to get the actual lock cylinder out is there's this

hole right here and you need a small punch you're going to move this guy over

to the start position press down on it and it comes right out alright so let's

take a look at this guy now we got him out I'll tell you why I'm taking them

out I'll show you a couple of things that can go wrong here

there's a locking bar here which locks into place when you have the key out if

you notice you put the key in this guy falls and comes up when you take them

out and you just watch it very carefully it's this guy right here then we're

going to move about a millimeter and then put the key any drops what will

happen is this thing either one of the springs on one of the sides will give

out and it'll get caught in a half down half up position and that's usually a

situation you have or you can't turn the key that's one thing it can go wrong

another thing that can go wrong and it's the case on mine is this guy right here

this plate that covers the tumbler Springs under here are your are your

tumblers that key the lock to your key and there's a set of Springs one for

each one and this this retaining bar holds them down this guy can pop up on

one side or the other and this one is actually my fault I changed this this

some out because I had this problem where one of these had gone out one of

these Springs on the locking bar I changed this out I brought the tumblers

over into the new GM ignition lock and I had recoded it from my key and I forgot

to stake the ends of this retaining bar to keep it from popping out and so I had

a situation where I could turn the key and it wouldn't start that was because

it wasn't going over far enough to ah turn you know to actually get ignition and

you can see when I had that situation where I had this in here and I had my

punch and I was trying to get this guy out and it kept poking right along here

because I wasn't reaching far enough in this hole to push this

retainer down which is what slides up under the hole when you turn it to the

start position this is what the punch is usually pushing down so you can remove

the lock I hope this ah helps you out of course reassembly is just reversing the

process you need to put the key back in of course before you do that you'll know

which way is up because of the indentation for the position of start or

run and knowing that you have this retainer up I'll put a light coating of

GM high temperature grease on here too that keep it nice and and freely moving

I hope this helps you out thanks for watching
