I just bought a 06 civic SI. The guy I bought it from doesn't have keys with control only spare I'm having problems opening door with key so I open the door manually and now the alarm keeps going off every time i open the door is there a way I can reset the security system to be able to move the car with out everything going off. Tips advices please Thanks in advance..

 

pay the $ to get real key.
or disable immobilizer

 

Check your local Honda dealer and see about getting the FOB keys for the car. And have them coded at the same time. Its a pain in the A$$ but it is much less a headache for all if it is done right.

 

Thanks.. got a new key with remote and reset alarm good to go.. Thanks again...
