I really didn't wanna ask for help here and tried to look for something online.
But I can't find anything else.

I bought a gp 99 gt 2 weeks ago.
The guy said he had a problem with the fob he had together really close. So he changed the battery. And it worked for a while and stopped.

I changed battery again.
Bought a new key fob
checked for radio fuse burnt and followed a programming

nothing worked. What else can it be. Watch the video. I did the programming correctly.
