QuestionI lost the remote device a couple of years ago. When I went to change the battery, the first time I had disconnected it since then, the alarm system turned itself on and I can't get it off. The horn and lights stop after 45 seconds or so, but go again when I open the door. And it won't start. How to disable? Nothing about it in the owner's manual, so I suspect it's aftermarket.
AnswerNo siren?
Not the parking lights?
And I am having a bit of trouble locating a Tacoma
1990 in my notes. Mine start at 95, so up to
that year, there was no factory alarm.
This is the horn and headlights?
That means you need to disable the factory
alarm system.
or try this.
Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, locate, press and hold in the
valet/overide button, found under the
dash area, (push button, spring loaded)
until the installed LED (the blinking light)
in your dash area goes on solid,
and the siren chirps once.
(Your valet switch might be the toggle
(on/off) type. in this case, key on,
flip switch in opposite direction,
then turn the key off.)
This should reset the alarm, and reset
the grounded relay on the starter wire,
allowing you to start the engine.
At this point, the only thing working would
be the keyless entry from the alarm,
if it came equipped that way.
Just Repeat these steps to place it
back to usable armed mode.
You may get 2 chirps, confirming it,
and the lights may flash twice as well.
That should do it.
If you want to remove it at this point,
take it to your neighborhood installer
for this, or buy the wiring chart
(Go to: www.vehiclewires.com)
for the vehicle, and reverse engineer it wire
by wire, until safely removed.
If it does not work out this way,
you will have to replace the system
with one you know how to operate
and what to expect. Don't want to
get stuck in another bad situation.
Let me know what happens.
