Default How do I disable the factory alarm on 1990 Lexus ls

Just bought a used 90 Lexus ls and I want to disable the factory alarm. I dont have the key that has the alarm buttons. Just the spare. Is there a wire I can just disconnect? Please Help!

Hi Python,
Will this work for a 95 LS? My Alarm likes to go off whenever it wants to. It's really starting to become a pain?
Thanks,
JT

So this wire I just need to cut and ground it out? Every time my car sits for more than an hour, when I unlock the door with the key the alarm goes off, and 9 times out of 10 scares the **** out of me, just started doing this a couple weeks ago..

No aftermarket alarm that I know of, or have seen. And I've had pretty much the whole drivers side of the dash torn apart. I ground the only solid green wire I could see, it was going into a blue plug. Not sure if it worked. When I lock the door, the security light is still illuminated, though, it stays solid whereas if i remember correctly, it blinked before. Is this right? I guess i'll see in the morning if my alarm goes off, car usually has to be locked a couple hours for it to happen.

Could you be more specific? Maybe what plug it goes into or a picture? I ground the only solid green wire I found, and still didn't work. I couldn't even get my alarm to disable this morning, so i couldn't start my car and had to get a ride to work
