So I had one key held together by tape from previous owner and one that came apart very easily. After reassembling the one without tape a few times I decided to just replace the key fob not thinking anything of it. I’ve since found it brings many unpleasant scenarios of not working right. Unfortunately I did both keys at the same time thinking it would be a great improvement.

The key fob guts are exactly the same; worked before the change; and after replacing the shell the buttons all work exactly as expected and the light lights like it always did when unlocking/locking the car. When I try to start the engine nothing happens.

I searched and found a few things I tried but I think they were all from slightly earlier models.
1. Put key in drivers door, turn left, turn right, remove, press a button. Didn’t work.
2. Put key in ignition turn left to accessories, hold down the hazard light button. Didn’t work.
3. Tried #2 with key turned to on (right) Didn’t work.
4. Tried #2 while holding down central key lock button instead of hazard. Didn’t work

I’m hoping that since the buttons all work that I’m just missing a step here and someone can help me out. Any ideas?
