I installed an aftermarket head unit and kept the old head unit using a supplied harness to keep the factory alarm working, but now only one of my key fobs works.

Yes, all the batteries are good. When I bought this car used, they guy had 3 key fobs. They all worked at one time, but somehow the other two non-working ones seem to have lost their "pairing" to the factory alarm module.

Anyone know if there's a way to reconnect these so they work?

1998 Civic EX.

Thanks

You don't have to keep the headunit plugged up. Here's the harness you need to buy:

No. you need the headunit plugged in, as the antenna for the keyless unit is built into the radio.

have you tired re-pairing it?

1. Turn Key to on position.

2. Push and hold **valet button on the stock radio. Door locks will cycle one time.

3. Press any button on remote one time within 20 seconds. Door locks will cycle again.

4. To program up to 4 additional remotes repeat step 3 for each additonal remote.

5. Turn key off programming is complete.

**Valet button is skinny bar located between am/fm & cd/tape buttons on stock radio.

So I finally got around to doing this and the programming worked, BUT when I deactivate the alarm and say I open the door because I'm putting stuff in the car and the door is swung open, I will get the civic's car horn go off three times "beep beep beep"...really annoying especially when it needs to be quiet.

Any ideas why this is happening?
