I second this. My car turned out to be the oddball 1 in 200,000 and the LMC5 didn't prevent the pull key message and the 2 mph fuel cutoff, which hit me repeatedly while I was out with with my car club. I spoke to him the next day and he had an LMC5-R and a second LMC5 on the way to me, which I received the following day. So far everything has worked just fine with the replacement and when I get back home from vacation I'll be installing the second LMC5 to see if the first was bad somehow.
Well my question is that if there is a "new" version or LMC5-R... why not just sell that one to people and skip the chance of it still having a problem?

2002 M6. I had the same thing happen to me but column locked. I installed LMC5 and the column error went away but continue to get the pull key message. I installed the LMC5R again pull key message along with the 2 mph shutoff. Funny thing it ocurrs spratically. Some weeks the car works like advertised and then I'll get the pull key message. I have a new batter, I cleaned the key and ignition key hole but this issue continues. I pull the key and wait 10 seconds and the car works fine. Richard from compliance has been very helpful and believes I may have a BCM timing issue. Not ready to splurg on a new BCM just yet. Hoping the compliance comes out with something that will address the 1% C5s that experience this issue.

You'd have to ask Richard that question. I don't know anything about the internal circuitry of either device. My guess is that a difference in the signal requires two different resistors for the device to work, which would not work if used in tandem. This would result in the need for two separate versions of the LMC5.

Installed the LMC5 today on my car.
After installing I let it run a few minutes and restarted the car about 5 different times to see if the PULL KEY message was going to continue to appear.
I have my fingers crossed but so far since installing it, everything is working fine.

Sometimes I just put the key in and start the car. It's a coin flip it the Pull Key message appears. Usually I turn the car on to see if the key message appears. If it does, it saves the starter.

I took my car on a trip this past week and was in a remote area and it gave me the message again and the car died at 2mph. It did this twice that day but both were random times. I haven't had anymore issues but of course it's going to happen again. I wish I could get it to stop doing it at all.

Whe you get the dreaded pull the key messages do you wait at least 10 seconds? The 2MPH shut off will occur if you try to drive the car with that message. When I start my car and get the pull key message and try to drive, my car will shut off too. You can get this tuned out but I'm like you I want to get this fixed permanently. Unfortunately, My BCM timing could be off and that I may need to get my BCM reflashed or get a new one. It's a funny thing, been driving my car all week and no issues. My pull key message is very random and I don't know what series of events I do that lead up to the pull key message. When I do get it, I pull the key and wait. If you listen carefully you'll hear a series of clicks when you pull the key and wait. It's kind of FU but I'm not convinced I need to put out the cash for a new BCM.

If the LMC5 works for you, it *should* last the life of the car, as there's no moving parts and it's an entirely sealed unit. If the LMC5 doesn't work and you end up needing the LMC5-R, there may come a time long in the future when the contacts on the relay don't make, and the service column lock message will return. I haven't seen an LMC5-R myself so I don't know if it's a common automotive relay in a replacement base or if its internal and sealed like the LMC5 unit.
From what I've heard, and I haven't spoken to Richard on this myself, is that the -R module with the relay has slightly different timing due to actual moving parts that will affect whether or not the BCM accepts the LMC5. If the BCM doesn't like the LMC5 there's a good chance the different timing of the LMC5-R will work.

Being the 4th or 5th owner of a C5, can I tell by a visual inspection if a previous owner has already installed the LMC5? My steering does not lock (currently) upon key removal, but I hear the footsteps.

Lmc5
I bought the LMC5 just in case I have this problem. Also got the unlocker, but that will only work after the fact. I bought this 2000 vert in June and don't know if the CLB recall work has been done. How can I tell? What do I look for? I haven't installed the LMC5 yet but want to do it right the first time. Thanx.

Lmc5
Richard from Compliance is the bomb! I've have never had an an easier experience with an aftermarket product install, or, for that matter, any other wrenching experience, I've done in the past. The directions were flawless. Richard gets an A+ for language arts. Photos in the directions were clear and self explanatory.
The product did exactly what it was supposed to do. Now I can blast down the back stretch at Road Atlanta and read my oil temp without having to reset the read out every couple of seconds.
Thanks Richard!

CL issues
Hey guys. Just my 2 cents here. I have been fighting this issue for a couple days on a 2000 auto vert. Tried a donor BCM. Ran the reprogram and all that jazz with it. Previously had the Dealer recalls done. I was installing the Bypass from Huston Corvettes. Nothing was working. In the end it turned out to be the Lock motor Relay. Yeah dumb. Here is the part#12177235. It is a general in stock part at your local NAPA or where ever. So maybe if anybody is still having the column fail messages and engine kill at 2mph, and have already done everything else, this is worth the $18.00 bucks. It is right above the BCM, so why your down there. 
By the way, I have been a Vette tech for 18 years now and this is the first time I have seen the relay be the cause of this.
Thank you and good luck.

Happens OFTEN, many thread on the forum where this relay and/or the GM K Harness have fried due to low battery voltage. Relay with insufficient voltage to operate will overheat and end up looking like the above relay.[/QUOTE]
I am planning on cutting this little bugger open when I get a chance. Thanks for the repy.

Salutations,
Tried most every tip in this thread to no avail. Unplugged both square relay connectors above BCM & reversed them ... steering unlocked but will not start at this point. Left key in number 2 position & switched the connectors back and now steering is locked with key out & unlocks with key inserted. Just thought since I didn't see this any where yet, I would toss it in for the guy(s) & gal(s) who are OCD like myself and cannot quit trouble shooting a problem until resolution. Thank you to all who have contributed to this thread, very useful information & very educational.
Very Respecfully,
George
