This just started today. It may be a coincidence but I got my state inspection today and got in to start it up and the service column lock showed up on the DIC. I hit the reset button and it cleared back to the mileage so I made nothing of it. I got home checked and cleared all the codes like 4 of them. But now everytime I start the car it shows up and I need to hit reset for it to clear. I had the LMC5 done like 3 years ago but not the brown wire mod so every once in a while I get the pull key wait ten seconds message. Today was the first time this other message appeared. Any solutions would be greatly appreciated.

Another thing, am I doing something wrong ? This whole C5 thing looks different .

I wonder if you have the same problem I had. Before I bought the car a dealer put in the GM fix. It was stuffed way up in the dash. So when I put in the LMC5 fix it had no effect. I finally discovered it when the car become immobile and I started following the cables from the LMC5
I found this, the GM fix that had failed and was intercepting the signal before it got to the LMC5. Here is a link to my thread with photos.

Do the brown wire modification. This will solve most of your problems.

Do I need to get ahold of Compliance to get the updated version of the LMC5 ? This issue is an annoyance more than anything as my steering wheel doesn't lock anyway so nothing can happen.

Anyone else please ?

Well I spoke to Richard at Compliance (real nice guy) and he gave me the solution to my most recent issue with the service column lock message. Simply disconnect the negative cable on the battery for two minutes then reconnect. Sure enough problem is gone, Thanks Richard.
