Hi Sir or Madam, welcome to Just Answer. I'm acuramstr. Is the car not starting or is the alarm going off at random? can you reset the alarm with the key in the door?

Hello Acuramstr,


I am sir. 1992 Acura Legend LS (Alarm goes off)

My car does not start at all. the alarm keep going off now, light blinks and the horn sounds. I got a new set off keys and still does not start up.

that did not work for me

Expert:  acramstr replied 6 years ago.

ok, first try locking and unlocking the passenger door and trunk with the key see if that reset's it. If not go to the security control unit and ground the green/red wire in connector 342 and see if that resets it. heres a picture of the security unit .

Ok, I have never seen one of these not reset when you ground the wire. I will open the question back up maybe another expert has another idea.

I have tried the last response but did not work. I am taking the car to the delearship to get it fixed. let me know if there is another option before I take the car to dealer.

Another Expert here.........

acuramstr gave good info & it is possible that the Factory Alarm Module is bad, it is "not"Factory (aftermarket or port installed) or the is a problem with the Ignition System.


Disconnect the Positive Battery Cable
Open Driver Door & LEAVE Open
Turn Ignition Switch to ON position & LEAVE On
Reconnect Positive Battery Cable
Alarm may sound for a couple of seconds
then try starting

If none of the above works, you need to have the System tested
