Just picked up a j30 from a police auction no alarm remote but there is an alarm because it keeps going off. I know my accord has an alarm kill switch do inifiniti's have one? If so where is it? Thanks people's

If it's aftermarket, your gonna have to take it to a pro installer to get it fixed. If it's a factory model, I bet the dealer will have to do it. Find the power wire to the horn and disconnect it for now until you can get a repair done.

Try this, I have a '93 and this is how you kill it.

It will automatically go off in 2-4 minutes.
If you don't want to wait, take your key and unlock one of the doors. Just put the key in the door and turn. It deactivates the alarm. Hope this helps
