Viper Alarm System

[Kluak]

I have a Viper alarm system in my 07 yaris. We bought it this way from a private party so i am unsure of the model.

When we bought it 3 of the 4 doors didnt lock or unlock with the remote. But the back passenger side door was the only one working but the alarm would work (the lights flash when you hit the lock/unlock button and if you opened the door with it activated the horn would sound and lights would go off.)

But now none of the doors work including the back passenger side door and the only thing the alarm does now is flash lights and make it so you cant start the car (so there is no horn and yes the horn works)


Anybody got any ideas on why this is going on and how to fix it?


I was just going to take it to a radio installation but if i can just fix it myself that would be awesome.


Thanks for the help.
