These instructions worked great on my 2000 Honda Civic HX!! I bout the remote on ebay for $20 because it seemed my original remote was going bad for some reason. The guy sent me some instructions, that had to do with a button on the original Honda radio which I had taken out several months ago. Called up Honda and the women said that most of the security systems are run through the radio unit. She said that if I had it professionally installed that the installer would most likely of known to take care of the security system, and i'd think that he did becuase the security system didnt have any problems. She told me that I would have to bring it in to get the mechanic to have a look at it and would probably cost me anywhere from $50 - 100 and I said hell no!! So i found this forum today and figured why not give a shot. Using the first set of instructions I programmed the new remote and after the 4th stage of turnin the ignition off and on, the locks cycled, so I thought it would be working. Got out of my car and tried it and nothing happened, then I tried my original and that wasnt working either???? Re-read the instructions and saw u had to also program the original again too. So started over, doing both and then the final set of instructions, both remotes cycled the locks. Once again I got out of the car, tried to lock and PRESTO!!! It worked like a charm! Shows that you should read ALL instructions before trying it! Thanks so much for the info.
