I went out to the carport to crank up my Z and got the dreaded pull key and wait ten seconds message. Since I had not had any of the other maladies reported on the model like oil consumption, I was in the blissful ignorance mode to this point and just did what the DIC suggested. When the recrank was done I got the service column lock message. I returned to the house jumped on this and the other forum and started down the suggestion list. I also fired Frank off a private email.

I ended up bailing early by going to GM roadside assistance and watched a very careful flatbed driver take my vette for a ride. Here is a summary of the suggestions, what is working, and what I now have learned etc:

1. There is a GM recall out that is doing a different fix for the automatic and manual C-5s (98-2000) but it is confused because there is a Vin number sequence and years covered that might include our Z06 in some parts of the document but not in others.

2. There has been a lot of support for the $65 after market bypass solution It takes less than an hour to install and has been relatively problem free). You end up being somewhat exposed for voiding the warranty on this mechanism but this is only if you go in for the recall. There is of course a minor potential increased theft risk.

3. If your problem originates from a connection of the wiring harness versus actuator motor difficulty versus relay difficulty different solutions will be required. (My problem was apparently the most common where the locking pin hung up in the slot even though I have an apparently good electrical connection.)

4. Several forum members have reported having vacations ruined and I can be stranded at an airport parking lot more than twice a week. TIP! Never park your Z without making sure your wheels are straight first because you will play hell trying to flatbed it if they are locked in the turned position.

5. I don't know if I got the process started by putting any steering wheel pressure on the column when I was cranking but I am strickly hands-off now.

6. Some say leave the air conditioner on for five minutes, resynchronize your key fobs, clean your key chip with alcohol, some say pull fuse 29 (some say 25), some say disconnect the battery. I would have danced an Irish jig with one leg pointed to the East if it would have helped.

7. Before I let the local dealer rip into my dash I tried Frank's suggestion and drove there to the garage and vigorously popped the wheel from left to right and mine freed up. Thanks Frank! The local service manager said to drive away this time since he didn't have the recall parts in stock anyway.

8. An alternative to Frank's suggestion is to load the steering wheel with your body weight to the right and then crank the key. This is supposed to lessen the pinch that might occur on the actuator pin. Apparently the new recall part has an improved relay in the assembly wiring harness that helps the little acuator motor have more muscle for extraction of the pin.

9. Hopefully our newest 2002 brothers and sisters have the new fix in their Z's and the recall replacements seem to be trouble free. The odd thing is the automatic transmission recall fix seems to bypass the column lock all together which raises a GM theft liabilty issue.

I thought I would put this back on your radar screen for comment as it seems to be able to happen to most of us.........

Rule number 1: Don't sweat the small stuff.
Rule number 2: It's all small stuff.

Thanks for sharing your column lock experience and observations with us. I will be picking up my '02 at BG in less than three weeks and I wonder if the '02s have the "fix".

I have asked this question before to no avail. Does anyone have an answer to this?

C4C5Specialist??

Chick??

Inquiring minds want to know!!

Bill,

Thanks for sharing your experience with the forum. /phpBB/images/smiles/icon_cool.gif Glad you are back on the road again.

I always fear that dreaded column lock. I've only heard of a few Z06's getting it.

Actually Sherylann came up with the temporary fix. I went out to my '99 Hardtop one morning and it too suffered from column lock in the locked position. After a lot of cussing and WTF's, I walked to work (live close). Half hour later Sherylann calls and says, "I fixed your car, come and get it!!" /phpBB/images/smiles/icon_eek.gif /phpBB/images/smiles/icon_lol.gif

When I had my Vette in the shop earlier this week, I talked to the service manager about the column lock problem. He is very much in favor of the bypass and said he would never void a warranty because of it.

As far as the column lock being able to prevent thefts, he said that it is totally useless. He said that with a quick jerk to the right, the coulmn lock pin will snap off allowing the car to be driven. In fact, when they receive a car locked up, they always just break the pin off so they can drive it into the service bay.

As far as I'm concerned, the column lock bypass is the only way to go.

Thanks IMA Z06, another thought on the theft deterrent feature. I had backed up to see how I could steer down my drive and the movement of the Vette forward is limited to only 3 feet when the column is locked before the electrical power to the motor is snuffed. It took 8 restarts to go back into my carport slot. Didn't sheer my pin so I am not sure if it would still shut it off if it had been sheered.......

I had the bypass installed!! One less worry. It was about $60.00 for the bypass and $20.00 or so to have it installed.....

That sucks! I guess I've been under the delusion it would never happen to me, but it seems as though it will, but only at the worst possible time. Oh well, what's another $60 at this point... :rolleyes:

Just had the Pull Key - Wait 10 sec message then the Service Colum Lock messag on my '01 Z06. Was going to back out of the garage to wash the thing. Used your suggestion of cleaning the key and Right / Left jerking of the wheel. What do you know it worked... boy I hope that thing does not come back. I have an autocross tomorrow.

Felkebg,

I'm sorry to hear this happen to you.

It happened to me just before the first C/F Cruise-In. I called for a tow truck the night before the start of the CI for them to come the next morning at 6 am, in Louisville, where we were staying the night with family. I went to the airport and rented a car so I could be on time the next morning. At 6 am the tow truck shows up, I tell him I will back the car up some for him to get in front of it and it was fine by then. Turned left and right , so, I sent him away rtaher than not have my car for the event.

That evening before, I was showing my 2000 Coupe off to family and couldn't even take anyone for a ride because of the column lock situation. Very embarrasing to say the least.

I got a c/l bypass when we got back to Dallas and started carrying them as inventory. It's the best insurance. I think GM should just reimburse owners for that cost of the bypass.

One would think they fixed it, however I have read of one instance on a 2002 Z06 that had the column lock up. Only one that I know of so far. Anyone else ?

Haven't heard of an '02. Mine locked up in June, but it wasn't the pin freezing. The actuator got stuck in the unlocked position, so all was good. The problem was that the PCM knew that the actuator had failed, and I guess it didn't realize that the thing failed in the unlocked position.

Any more than 3mph and the PCM shuts down the fuel, and the engine cuts out.

What I did to "fix" it was pull the neg battery cable for a few hours, then it would start up and drive around. Not really a viable solution for driving, as the problem will occur as soon as you turn the engine off, but it'll work to get you home.

I wasn't aware that cars of my vintage had the problem. I think I will order the bypass since from comments, it isn't much of a deterent for a professional. I always leave my keys in the car at home, and often when I go places. We don't have much car theft up here, certainly no professional thiefs.

My 02 got stuck in the unlocked position at 1300 miles, it triggered the body module theft deterent and stranded me out in the sticks. It took the dealer 6 days to figure out that he should change the column module. I bought a bypass kit and keep it in the car along with the necessary tools to change it out. Haven't had the problem since and am at 3000 miles now. I am trying to get GM to pay for the tow because it was beyond their limit of nearest dealer but I didn't rent a car so it balances out .

So far the COLUMN LOCK has not come back. I ran an auto-x Sunday without a problem. Could I have caused the problem someway??? I hold my breath every time I start the engine. :-?

I have an 01 Z06 with 4000 miles.
