I have a 2006 honda coupe EX SI, I believe, and whenever I press the buttons on my key to unlock my car it doesn't work. Even the lock and trunk buttons do not work. When I press the trunk button on my keys to open my trunk, i can hear the trunk actually opens, but doesn't pop up. Whenever I press the unlock/lock/trunk buttons on the key the little light near the lock button lights up.

I hope you guys understand my problem.

P.S. it was working yesterday when I drove back home, but the following morning it doesn't work.

 

I don't know how your fob is setup but in our 6th gen 96-00, the fob's battery gets a bit dislodged occasionally and it will reset the alarm as if you have just changed the alarm battery. This then requires me to hit the button six consecutives times and it will re-establish connection with the keyless system. maybe that is happening to you.

the solution is to put a very thin piece of plastic or some paper to push the battery down on the springs to get a solid connection. I don't know if this will solve your issue however.

 

@mundy, you say you have a 6th gen civic 96-00 can you please tell me which fob it is that i need to control the locks and stuff on my gen6???? my civic is a 96 i diddnt get a fob with the car and am desperatly looking for one. my neighbourhood is a bit ropey so an un alarmed car tends to not last very long.lol.
