LMC5 Module - C5 Corvette steering column lock bypass module Black

I have a 1998 Chevy Corvette and I installed this for peace of mind, even though the column lock was working perfectly. I didn’t want to risk the chance of it failing and you being stranded somewhere, especially because I travel such a long distances in this car. Install was extremely easy. The hardest part is getting the old pins out of the plug, but with some patience and wiggling they come right out no problem. This is something that anybody can do with almost no tools.Something worth noting is that the early C5 Corvettes used a different body control module than the later ones. 99% of the time, these cars have no issues with the LMC5 but unfortunately mine was one of the weird ones. I would get a "pull key wait 10 seconds" notification on the dash every 30 or 40 starts and have to restart the car. I called the manufacturer and spoke with Robert who was extremely helpful and sent me a different module specifically for my car, free of charge. The new module is significantly improved. I would recommend this to anybody looking to eliminate a known failure point.Thanks for the help y’all!

This is s great product and tech support is superb. I have a very custom 2001 Corvette (convertible , 6 spd) with a 1962 carbon fiber body so I am loath to have work done at the dealer. In any case, a few days ago the steering wheel locked-up (in my driveway thankfully) and in researching the problem I found that 1) this is a very common problem with C5 Corvettes and, 2) the LMC5 product was widely used and favorably rated everywhere. In my case because the wheel was already locked, I needed to purchase the kit with both the LMC5 and the Unlocker.The instructions are extremely detailed and one can also find helpful installation videos on You-tube.My situation was one of many different types of iterations of the problem, and not all troubleshooting techniques can (or should) be covered in the written instructions for the “unlocker” tool or the instructions would be the size of a phone book.In any case, after trying the most likely fixes outlined in the instructions to no avail, I spoke to Richard in Tech support and he walked me thru alternative methods for freeing up the steering column lock, which is done before completing install of the LMC5 product (which then basically bypasses the steering column lock permanently).All and all , a great product and phenomenal tech support.

Man, I wish I'd known about this product a year or two ago. I'm the original owner of a 2003 50th anniversary coupe, and I had all the recalls done, the ones meant to prevent a steering column lock.And yet, I got the column lock anyway, in October 2023. Middle of the GM strike and some related supply chain issues.It got towed to a local dealership where they banged around and failed to fix it for a full nine months, before finally replacing the entire steering column with a mangled, mangy, scratched up junkyard salvage, in my otherwise pristine vehicle. And of course they charged me for the privilege. But at least it was fixed, right?Well, so I'd hoped. Three days ago, I started it up, backed it out of the garage, and the wheel was locked. No message this time, just, no steering. I topped up the battery, read a whole bunch more in the Corvette forums, ordered this LMC5 from Amazon, *fortunately* got the wheel unstuck, pulled fuse 23, did the install, and now I can steer my car again. I'd imagine I could have saved thousands in ineffective repair work if I'd have known about this device sooner.So, TL;DR, if you have a C5 and even if you think you've done the recall work to prevent the steering column from locking....it's probably going to fail. Unless you install something to actually fix the problem.This is the something. Under $50 and took about an hour (it was 105 in the driveway so I took frequent AC breaks, and getting the old cables to release is harder than it should be when you're an old dude with bad eyes....use a jeweler's screwdriver instead of the hex wrench, or just force 'em out with a needlenose, you're not going to need them after the override.)

It’s great, it worked, fast install great instructions

I bought this because my steering column got locked up. It did what I needed it to do. I had some trouble with the installation, and I called the customer service number, and he was helpful and walked to troubleshoot it. Everything works now will be recommended to others when facing that problem.

Update: I did the optional “Brown Wire Modification” which seems to have worked. Time will tell…Initial review: Fixed the problem for about a week and the same issue is back again.

Excellent product - clear instructions for install.

I took my time with the installation of the LMC5 module. The instructions are very clear to understand. I like that the instructions took into account many possible scenarios the installer may confront. I think that it helps to not jump into conclusions, as far as whether to install the brown wire or not. After the installation was completed, I had both doors opened when I turn the key to on, but I did not start the car. The first thing I saw was door ajar....so I turn the car back to off. Closed the car doors and turned the car back to the on position a second time. I did see only once the pull key message, so I thought that maybe I needed to connect the brown wire, but I thought that maybe the BCM may need a third attempt to reset or configure itself. I choose not to connect the brown wire and started the car. It ran fine and no pull key was seen. I test drove in my driveway and then took the C5 corvette for a long 60 mile drive. I had 6 successful starts with no pull key message, so I am assuming that the brown wire is not needed and that the module works great. The reason that I installed the LMC5 was that my car (May 1998 - Corvette, Automatic) started to shut off after barely going forward and backwards too, as people describe it "2 mph shutoff. " I believe that this module has fix my issue. I feel so much safer with the LMC5 installed on my Corvette. Thank you.
