So I lost my keys a few weeks ago, searched everywhere, checked different places with no avail. So I had to pull out the spare set and use those. Only to find out that the key remote didn't work. Went to the store, bought a new battery, still nothing. so I gave up.
Now I want to get it working, so I looked up how to program a remote.
Followed every step, The car confirmed it was in programing mode by cycling lock & unlock. It then says to press both buttons on the remote, and if it cycles again, it worked. The website says to turn the ignition to the on position, and back to off to finish programing. It then says to test it. That's where my problem is, it programs, works while programing, but afterwards it doesn't reply to and of the buttons...

Any Help at all?

P.S. The previous remote worked perfectly fine before I lost it.
