Programmed key fob but it doesn't work
tried to program all Key fobs yesterday, and my Corvette looks like registered my new(purchased) key because DIC display counted up key sequence.
However these new key doesn't work, even though lock/unlock button. Should I do something?
But I could program used key correctly without any problem.
Do you have any suggestion?


Do the part numbers all say the same thing? (Must be the correct # or you'll have trouble)
A used FOB can be programmed if it is the correct part #.
Use this EXACTLY to program the FOBs:

And all 3 fobs are same item number.
only different procedure is firstly I programmed used one.
And once completed programming.
after that I tried to program new one both of them with repeat procedure.
Should I erase program for new ones?


1) Do you have 1 FOB with the car and are adding 3 more?
2) Do you have no working FOBs and are trying to add all 3?
Or something else?

Let me share current condition,
I have 1 original key FOB.
I wanted to add 3 newly key FOBs.
one of newly key FOB is secondhand but it's virgin.
Other 2 key FOB is brand new condition and they are also virgin.
I tried to program secondhand key FOB and it was successful.
DIC monitor accepted with key number #3 for second hand key.
And I tried to additional program other new condition 2 FOBs.
And DIC monitor looks accept registeration to add them as #4 and #5.
I might forget to push unlock button after registration...
But I push engine start button for 12 seconds as final step.
I processed programming again for newly 2 FOBs because they were not active.
DIC monitor didn't count up key number. currently it shows Ready for remote #6.


First, in the warning notes at the top of the linked PDF, it says: Also: European Spec cars cannot do the short or long procedure. All remote programming must be done by the dealer.
I see you are in Nagoya. Do you have a European Spec car? If so, my instructions won't do you any good and you will need to use a dealer to do the programming.
If your car isn't a European Spec car then you can continue below.
OK, you need to start all over with all 4 FOBs. You should do the programming as though you have NO active FOBs for the car. Do the "LONG" program. Step 1, 2, 8, and up.
This will give you the following
FOBs 1 & 2 (the 1st and 2nd that you insert to program) These two will have memory functions just like the OEM set that came with the car.
FOBs 3 & 4 (the 3rd and 4th that you insert to program) These two will NOT have memory functions but will allow access to all car openings and they will start/stop the engine.
Follow my link in post #2 and do everything it says. Pay attention to the red text as that information is important.
Step #8 says: NOTE: Make sure NO old remote transmitters are
anywhere near the car. THIS IS IMPORTANT!
Do not have transmitters near the car!!!!!!!!!
Let me know how you do!

Just FYI -- there is absolutely NO difference between a 'new', virgin, never-used C7 fob and a 'used' previously-paired C7 fob. Absolutely NOTHING inside the fob changes when it is paired with a car. NO memory changes, no info of *any* kind for the host car is stored/changed in the fob. When you pair a fob with the C7, *all* the 'learning' goes on *in the car*, NOT the fob. Simply put, the Car memorizes the ID of the paired fob -- the fob does not memorize/store anything about the car.
Thank you for your reply.
At first let me confirm short and long procedure definition.
My understanding is short procedure is "Programming with recognized transmitter" and Long is "Programming without recognized transmitter" am I right?
My vehicle is US spec. My local car shop imported personally from US.
So I can proceed your suggestion.
>you need to start all over with all 4 FOBs. You should do the programming as though you have NO active FOBs for the car. Do the "LONG" program. Step 1, 2, 8, and up.
Do you mean even though I have recognized transmitter but I should program without recognized transmitter method for all of 4 FOBs?
As I wrote in this thread, FOB#1 and FOB#2 is already activated but should I re-program #1 and #2 with long procedure?
I afraid that current working key FOBs also become NO active key FOBs.
But according to your suggestion, this is only method to program for all 4 FOBs.
Is there limited number of registration FOBs?
Sorry for asking many.
Thank you very much!

If you start "Fresh" without a FOB (even though you have one) the programming starts at 1, 2, 3, and then 4. This gives you 1 & 2 with memory and 3 & 4 as door/engine FOBs without the memory function.

If I have long program for unrecognized 2FOBs(I will not long program for recognizes key)Is there any problem in recognized 2 FOBs?

You must do the long program to get FOBs #1-4 (This starts a new sequencing of the FOBs to be 1-4)
You must do the long program to have FOB #1 & #2 to have memory capability.
Short program ONLY ADDS FOBS 3-8. It will not make #2 have memory.
OK, does your FOB 1 & 2 have the memory capability? Do the keys in the FOBs open the rear hatch/trunk?
Have you had the keys in the FOBs that you bought cut by the dealer to work the rear locking mechanism?
By "Key" does not work are you referring to the internal key contained in the new FOBs? They must be "cut" to the specifications of the locks by the dealer.


22779879 TRANSMITTER W/O REMOTE START M7
22779880 TRANSMITTER W/REMOTE START A6/8
And I don't know memory capability.
There are lock, unlock, remote start, horn, hatch and rear open button on FOB.
I have only 2 keys, one is original another is uncut key that i bought via eBay.
How can I check whether my FOB has memory capability or not?
I appreciate your super support!!

Turn off the car. put FOB#1 away from the car.
Use FOB#2 Set the seat for some setting that you know you can tell it is different from FOB#1. Use the "set" buttons to remember that seat setting.
My wife has FOB2, when she gets in and starts the car, the seat rams forward a bunch as she is short so she can reach the pedals.
When I get in with FOB1, the seat doesn't squish me to her settings but it goes to the settings for me (taller) so I can reach the pedals.
Your 1 and 2 FOBs have the memory to do this automatically. Fobs 3&4 will unlock the doors and operate the car so you can start it and drive. The seat setting will need to be manually set for FOB3 driver and FOB 4 driver MANUALLY each time they use the car.
So I will try the programming as follows;
i must program again with long procedure for all FOBs that are 2 recognized FOBs and unrecognized FOBs.
after that, I will set seat position for FOB 1& 2.
Thank you very much!
