Problems with the factory alarm on Toyota Supra '87

[Ogheen]

When I have the car locked and then unlock it the factory alarm goes off and it wont stop. It's been happening way to often lately. The way I deal wit it is i pull out the radio fuse and the alarm stops. So now every time I lock the car I take the fuse out and put it back in when I unlock it but it is a hassle.
I would like to get the factory alarm disabled but I have no clue how.
Anyone has any ideas or suggestions?

The post to explain how it's done is here on the fourth post down: http://www.supramania.com/forums/sho...=1515#post1515 Personally, all I did was unplug the TDC (Theft Deterrent Computer) and then grounded the blue/orange wire, but it's up to you whether you completely remove the TDC or not. Hope this helps!

check it out my supra is an 89 and the alarm is all haywire as well when I took out some of the fuses it would start its the same fuse for the radio...if that helps take it out it will start then put it back in while running now your radio will work I hate it but if its too much of a hastle for you car quest will take out the stock alarm for 150$ for you and problem gone...
