I had the same problem some of you were having getting my keyless entry into programming mode. No matter what I did I couldn't get the lights to flash. Skip forward a couple years to today, I was checking fluid levels under the hood before a road trip and saw the control box on the drivers side that said Keyless Entry on it, and thought maybe I should take a quick look under the panel. Everything looked OK - the brown box was where it should be. I tried to remove it but only got it part way and didn't want to force it and risk damage so I just stuck it back into place. It felt like it reseated so I hopped back in the drivers seat, locked the doors, stuck the key in and out, in and out, and right when I was about to give up for the last time it flashed. I turned to aux, hit a button on the keychain and I NOW HAVE WORKING KEYLESS ENTRY!!! I'm pretty excited.
