99 honda locks and alarm trouble

Hi My name is kirk and I just bought a 99 honda accord and the locks and alarm are not working correctly. The remote operates the driver door only. The horn does not sound when the lock key on the remote is pressed twice. The frount door lock switches will operate the driver door only. The other doors you hear a click only but the locks do not move up or down. If you can give me a idea abouth what this trouble is please let me know.

the doors , hood and trunk must fully be closed for the alarm to arm. if this is still the factory alarm .if not check the door pin switches to make sure they are working properly.
