1999 Honda Civic Remote Keyless Entry System

Hello Cathy

It does indeed have keyless entry. It needs reprogramming when you get a new remote. Also if you disconnect the battery. Usually a local car alarm fitting shop, or an auto-electrician will do it. Plus of course a Ford dealership.

First thing is to try passenger door (that still has key lock for '03, doesn't it?) Or the rear hatch. I'll bet it won't work there, either, unless battery is disconnected. My guess is that the remote locking is staying at "lock" - which is why it works with battery disconnected.
I haven't heard of anything just like your problem, but there have been many who have to replace the RKEM (Remote Keyless Entry Module) - it's behind the radio. Usually the doors start to lock & unlock by themselves.

Try locking and unlocking the doors with the key to see if it will reset the security system.
It is possible a relay could cause this...there are many relays and computers in this hybrid system

TRY A NEW BATTERY IN UR KEYLESS REMOTE

The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

it would be quit a job to set your car up with a keyless remote.unless you found some one very very very good whit wire.but to tell you the truth i do not thik it hwate of time . it would cst a hole lot of money .hope i help you

inspect and or replace the drivers door lock actuator...

Okay, here goes-

1. Turn Key to on position.
2. Push and hold **valet button on the stock radio.
**Valet button is skinny bar located between am/fm & cd/tape buttons on 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.

Thanks for using Fixya, please rate if this helps :)

this maybe a long shot. but i feel that it could be your remote. the "chip" inside your remote could be weak in frequency.
