Program Chevrolet Corvette C7 key fob with GM MDI2

Here we share a user experience of programming Chevrolet Corvette C7 key fob with GM MDI2 clone and Techline Connect SPS2.

I lost my only key fob for my 2014 Corvette C7. I have an ACDelco Techline Connect dealer tool subscription for this VIN so I can do all software updates. I’m using a GM MDI2 clone that works great. This allows me to put the car into accessory mode without having the key (it seems) as it allows me to access the immobilizer’s learn/relearn option.

It was one of those cheap Chinese knock-off MDI2s. The beauty of this is that launching the tool will still pull the firmware updates from AC Delco. The official apps consider it a real device. So far I haven’t had any problems with it at all. It was kind of fun clicking through every computer module in my vehicles and finding newer software versions. I don’t have the keys or any keychains. I’ll see if I can do a \”learn new\” with it without having a key in the vehicle (programming a fob without having the original key).

I did some research and found that if you have a key you can program on the C7. You can lose both FOBs and program the new FOBs to the car. All you need is the key or the cool stuff the OP has to get it done. But you should still have a key! The FOBs are not programmed, the car is programmed to recognize the FOBs.

I programmed the new trailer and now I can lock/unlock and start it! This was done without either FOBs or keys. I used the TechLine SPS2 tool and the MDI2 to update the ACDelco immobilizer. They’re great tools for cases like this, and a VIN subscription costs about $45 for 24 months!

With my c7, all I had to do was be in the vehicle with the GM MDI 2 scanner connected. With the Techline software, I can connect to the vehicle and carry out software updates on any computer module. This also includes the programming of replaced parts (new control unit without VIN). I would like to point out that if you are programming a new FOB without a key, there is a built in 15 minute timer that you MUST wait before proceeding to the next step. The whole process takes another 10-15 minutes when prompted (press start button), press next (hold start button for 12 seconds), press next, etc. I think the built in 15 minute initial delay prevents quick steals , but that’s no less scary -less that it’s even possible without a key. I definitely agree on that part! Again, these are dealer tools. I’m just a techie who likes to do my own infotainment and other software updates myself. I just got lucky and had this tool when I lost my key and wondered if it would work.

I have a 2014 model that had a dark dashboard display at dusk, so I used this to update all the modules needed to fix the issue. It looks like most of the modules were up to date, but I found maybe 5 or 6 that I updated to the latest versions. I also used it on my GMC Acadia and it fixed some of the quirky infotainment bugs.
