Car Alarms: GM security bypass, power disruption, security light


Question
QUESTION: On 1-21-10 I purchased from you a security bypass switch for my 2000 Alero. It has been working fine until this past month, when it would take two to three times before it would start. Now the car will not start at all. My mechanic that installed it, reset it with his computer on Monday and it started right up. I drove it for the 1st time today and the first time that I shut it off, at the grocery store ;( it would not start. I tried letting it sit for 10 minutes, nothing. I tried the reset button for the switch, nothing.
I would give you the part number that I bought but it is in the car, at the grocery store parking lot.
Has there been other problems reported for this switch? Does it have a warranty?

Thank you,

Romona

ANSWER: Hmmm, well 1 thing here is if your car lost power or
the battery was taken off ata anytime last month, then
the module likely needs to be reset and it looses programing
when or if that happens. This is the reason we also sell and suggest
a backup battery in this eventuality. This may not have been
purchased or added at time of install, and now the module
needs to be re programmed.

Get it back to the tech that did the work to reset it,
but for now, try the key learn method of turn on key
to just before cranking, and leave this way for at least 10 mins.
The security light would go off, and you should be able
to start the engine.

Passlock 2 should then be "learned", and allow it to
start. That does not always work, but if all things being
equal, it worked well for months, then it stopped,
it usually means a power disruption caused the module
to loose it's set up programming.

You need the tech to get in there to redo it.
The module is warrantied against manufacturer
defects and as long as it was used
for it's intended purpose of remote starting. See that
explained on the site you got it from www.GMPASSLOCK.com .
If used only to bypass Passlock, then no.

However,

If found to be burnt or, installed correctly and has damage,
it can be exchanged for another module, and that would
only cost you shipping to return it to you.

But I don't see allot of malfunctioning modules here.
It is usually an installation issue, and the tech should contact
our service technician to go over the notes at anytime
if purchased here. Check your email for that persons
name and number.

But for now, the best thing is to have it towed or
get it temp started using the 10 min. cycle and get
it to the tech.

QUESTION: The car has not lost power and there has been no battery disconnection done.
The tech reset it on Monday and checked the entire system with his computer. It showed no problems and the car started. Wednesday was the first day I drove it and the first time I shut it off, it would not start.
I tried the key learn method, waited 15 minutes, the security light was still on, it would not start. I then tried the bypass button and that did no go either.
My tech met me at the car about 4 or 5 hours later to reset it again. Before doing so, he tried to start it and it started right up.
Now I am afraid to drive it because I don't know if it will start, when I shut it off.


ANSWER: Have the starter evaluated ma'am. We recently had a 2001 Monte Carlo exibiting the same thing, and once checked, it turned out to be a bad starter solinoid. Once they replaced the starter, al
was fine. These bypass kits hardly ever fail. You can of course
pull it, send it here with shipping cost included and
we can replace it after bench testing. If found
bad, an over the counter exchange will occur
and we'll send out a new one.

But from experience, if it was working fine, and now
it's not, there is another trouble.

It's usually attributed to a bad power issue.

QUESTION: Bob,

Yes, it's Mona from Orlando again ; )

O.K. have elimated starter, alternator, battery (3 months old) taken it out twice and back to the parts store, parasitic draw.
It always cranks, just doesn't start. On a fluke, my neighbor, a diesel mechanic, had me put the key on acc for about 5 or six seconds and then start it. It started every time. I let it sit from Saturday til just now, put the key to acc for 5 or 6 seconds and it started right up.
My question, is there something in the bypass, that is now needing 5 or 6 seconds to read the code before it works? Or 5 or 6 seconds of warm up power?
I went out Saturday 6 or 7 times throughout the day using the same steps and it started every time.

Have you heard of this happening before?

Mona


Answer
The delay is interesting. No I can't say I have heard of that.
But I have a thought...

Sounds like one of the wires the bypass kit is attached to
may not provide the 12 volts source for a couple of seconds.

The tech might want to reassign the power or ignition wires.
and if not using the "key sense" (green in the ignition harness)
then have him do that too, and then program, then ground
the brown input (-) wire to the frame.

Hope that helps.

Bob.

(Also write to my tech Don@alarmteks.com as he may be able
to provide additional input here. ;>)  )
