Car Alarms: Alarm going off intermittently, siren sounds, toyota celica

Question
QUESTION: I have Toyota Celica 18ST P reg. For some time now every now and then the alarm will go off for no apparent reason (sitting in the car park or on the drive). The other day when I was driving the car the alarm siren went off but I was still able to drive the car?

ANSWER: Please be more descriptive if possible.

"GOING OFF?"

I need to determine whether it's a factory alarm
issue or, if it's an aftermarket system you are
dealing with.

Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?
(doubtfull since none of the notes show this
car as having a factory alarm system)=FACTORY

Or,

is it: flashing parking lights,
an LED in the dash area, and a siren
going off?= AFTER MARKET

QUESTION: It would appear to fit your second description of an after market alarm. By "going off" I mean the siren sounds and the hazard lights flash.

Thanks

Answer
You'll need to set off the alarm for a few seconds.
Then, look under the dash area for a button or, a toggle
switch. When you locate it, turn on the ignition
key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.

At this point. the alarm would have reset.
If this had a starter kill relay installed,
it would now be opened, and the engine would
turn over when tried.

You would repeat these steps to go back to
user mode to see if this was corrected.

But if it does work, I'd keep it this way, and
replace the alarm asap with one you know and
understand how it operates for the best overall
experience.

Let me know if it works for yours.
