Car Alarms: 2006 Scion XB Alarm, scion xb, cold periods


Question
QUESTION: I have a 2006 Scion XB and my factory alarm goes off randomly, like today twice at work then this past weekend two to three times. What could be causing this?

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.

Ok let's clear up the terminology glitch here.

1. FACTORY/OEM alarm = Part of the original schematics
and plans from the manufacturer.
(horn honk, head lights flash, Starter may crank and
die, no spark)

2. DEALER INSTALLED alarm = Just that. Once the vehicle
is brought to a dealer, the dealer sub contracts the after market
security out.
(horn might honk, siren and parking lights flash, starter kill relya,
no start, no crank, just dead.)

3. AFTER MARKET alarm: Same as #2 but Customer IS AWARE that
the system was put in at the dealership, but may not
be informed of the brand name, or even what it's
total capabilities are.
(siren & parking lights flash, starter kill)

Which one applies to yours?

QUESTION: #1 Factory and I have seen alot of posts about this same vehicle problem but no one has a solution? Thanks in advance

Answer
Ok, "Factory" alarms trigger by perceptible battery drain.
Usualy when a dome light goes on without the benefit of a key
in the drivers door. It can also react like that during
very cold periods. Batteries must be checked periodically
and directly after or befor a freeze.

The alarm would then react to a spike in power as
it is designed to do and is reporting it.

Try to replace the battery with a new one to correct
the issue.
