How do I deactivate the alarm system on a 1998 sc 400 Lexus
The car will not say anything. The radio works, the lights works. the power door lights
works. the power seats work but the security light constantly flashes and when you put
the key in the ignition and turn the car won't say anything.
Because of the Security Nature of this concern, you're best bet is to have the Dealer repair it. Usually, you can not deactivate a factory equipped alarm system.
