Sounds like the frequency is the issue. If the new one doesn't have the same freq as the old one, then there must be a part number issue???? It's going to be hard to check on the frequencies of the RKEs.

Something is hosed up on the part numbers.

I have a C7 2016 Z06
I got a new GM remote
when I first got it all the buttons on the remote worked but obviously the car wouldn't start
I followed your directions
The car will start now
But the buttons on the remote do not work
Any ideas?

eboggs_jkvl

Did you press the "Unlock" button after the programming?

Maximus68

Yes. I pressed unlock then hit the start button for 12 plus seconds
It's weird. They worked when I got it and now I got it to start the car but nothing else.

eboggs_jkvl

I'd do the whole long program again. Something is amiss.

I'm reading thru the forum posts
People are saying and talking about a frequency issue
My lock/unlock buttons worked right outta the GM part bags
Could I have some how wiped them out?

eboggs_jkvl

Probably not. You may have the wrong frequency and I can't do anything about that. If the RKE is the correct one for the car, the instructions should fix it right up.

It is definitely the one for the car. Straight from GM to the dealer to me and all the buttons on the remote worked before I had started any of this. Are these the steps
Open hatch
Turn key five times
Reinsert key
Put fob in column(how long does it stay in for?)
Take out then.....
Press start for 12 seconds then unlock or
Pull it from the column
Press unlock then start for 12 seconds

Maximus68

Here is another thought
Is there anyway to change the number from 2 to say, 5?
Can I put a different number?

I do know that if you attempt to program a fob that works on a different freq., odd, sometimes scary things happen.

I have an extra C6 fob that I tried to program to my C7, and not only did it not program the C6 fob, it temporarily, partially unprogrammed my working C7 fob. Fortunately, after the car timed out and went to sleep, the fob started to behave normally. Whew!!!

owc6

Fob number is strictly determined by which order you have it programmed. First one programmed is #1, second is #2, and so on, up to 8 fobs.

Maximus68

Ok. I will try it again
It's weird how it worked
But now it'll start the car but the buttons don't work.

owc6

Have you tried letting the car sleep? Then check the fob buttons?

It takes about a half hour to make sure the car is truly timed out.

Maximus68

I just tried that. It didn't work.
I will try it again tomorrow and let you know how it goes. Thank you for all the help.

Be sure to do the long program, not the short. The short program adds #3 and up. THe long program starts all over and the first RKE inserted is #1 and the second RKE is #2.


Elmer

To be sure, the long program is when you wait 10mins 3 times, correct?
I have to put the working key fob in with that? I am a little worried-that one works. I don't want to be stuck with nothing working. Remember, the one I got new from GM initially, right out of the bag, unlocked the doors and hatch-no car start. Now it starts the car but no buttons work.

In the manual, the section that says PROGRAM KEY FOB WITH ONE WORKING FOB-something like that. They tell you to put the working key fob in the cup holder. What is with that story.

eboggs_jkvl

The Long Program is STEPS: 1, 2, 8, 9, 10, 11, 12, 13, and after you have all of the RKEs programmed, step 14.


Elmer

Maximus68

Ok. So if I do that long program, do I have to reprogram the completely working key fob that I have?

eboggs_jkvl

Here's the thing...

If you have 1 RKE and add a new RKE, it becomes #3. It does not have all of the memory functions that the initial RKEs 1 & 2 had when the car was delivered.

If you only have 1 RKE and you want to add a new RKE to act as #2 WITH the memory functions, then you must do the long method. The long method clears the old RKE and starts anew when it gets into programming mode and the first RKE in the slot at programming becomes RKE #1, the second RKE in the slot becomes #2.

Pay attention to ALL of the NOTES in RED!


So, answering your question, yes, you are reprogramming the existing RKE. If you only have 1 RKE, the missing RKE will operate in your car. After you do the long program, that RKE is unable to work your car and the 2 RKEs you end up with are RKE 1 & 2.
