Help, please: Silverado key will not turn.

Help, please: Silverado key will not turn.

Postby Mark53 [OP] » May 10 2013, 5:13pm

Help, please...

On a 2002 Silverado 1500, all-of-a-sudden the key will not turn.
The gear-shift lever seems to be stuck in Park,
but the steering wheel does move. The key is removable.

I've searched this, and other forums, and found some suggestions:
1. tap the key with a hammer; didn't help.
2. unhook the battery for several hours; didn't help.

I followed the Haynes manual to remove the ignition switch...
disassembled many dashboard parts, to get access to the switch...
now, it says to turn the key to "on",
then push the pin thru the access hole, and the switch will slide out.
That's cool, But I Cannot Turn The Key . :(

Underneath, I disconnected the trans cable at the trans,
and with a wrench, I was able to shift the tranny into all of the gears.
Still, the gear-shift lever will not move.

Any ideas, people?

Thanks very much, in advance.

I'm guessing the steering wheel lock is activated. Try to turn the steering wheel, maybe the key will turn that way....It can be difficult to get the wheel to turn.

Maybe its a bad key? Buddy of mine had this problem a while back and a new key is what fixed his problem.

Im with voodoo, before I got rid of my del sol every so often this kind of think would happen and I'd have to wiggle the steering wheel to make it unlock.

Something may have gone bad with that key. I'd go to the dealer with the vin and get another one cut before I dismantled the steering column

Thanks for the replies, gents, but the original post says that the steering wheel does move.
The steering wheel is not locked.
I also tried slamming the adjustable steering wheel height to both extremes; didn't help.

I tried the spare key that's normally in a desk drawer; didn't help.
(I did read a post somewhere about a guy who's "friend" played a practical joke...
switched lookalike keys. Same circumstances as my current problem. I'm sure that's not the case here.)

It took the moderator three days to approve of this post.
In that time, I've disassembled what I could.

Image

I removed the white plastic wheel (A) in the middle.
Then, I removed the big black "controls assembly" (B) on the left side (just for the heck of it).
With the (A) removed, I had access to the two torx screws that hold on the ignition assembly (C).
I removed that... and with that assembly in hand, the key works. It can turn.
I put the ignition assembly (C) back on, and the spare key works,
but the most-used key (quite worn) works rarely... only after playing with it for a while.

SO,... I took it (C) off again, and after some time, I was able to slide the cylinder out.
The cylinder sometimes acts as it should, sometimes not.
Sometimes, it won't turn all the way to "start".
I think something inside the cylinder is messed up.
Time fer a new cylinder, me thinks.
Unfortunately, that means different keys for the ignition and the doors. Ah, well...


Woops... another problem...
In reassembling, I have a spare part...

Image

I vaguely remember that it was a secondary holding/mounting for a wire/cable?
Anybody know where that little plastic piece (about an inch long) goes?

Again,... thanks.

If you go to the dealership, to get a new key and cylinder, they can make it to match the other locks.
The white plastic piece in the pic holds the microswitch on the rear of the cylinder, if i remember right.

Mr. Moderator:
I didn't realize that I had posted it in the wrong place.
I apologize. I meant you no disrespect.

Thomas:
I've tried to fit that piece into any place near the micro-switch at the back-end of the cylinder.
Can find any appropriate place to put it.
The micro-switch that I'm referring to is the one that is activated when the key is inserted.
Not turned,... just inserted. Still,... can't find a place for the plastic piece.

Any other ideas, people?

Again,... Thanks very much for the input.
