Passlock SUCKS!!!!

MaximumOD · June 19, 2006

I have a brand new 2006 2500HD 8.1 4x4 Allison tranny. Waited two months two get it and have issues a month later. When I picked up my truck a month (5-6-2006) ago right away I went to a shop and installed an alarm. Last thursday while driving the lock indicator lit up on the dashboard. The following morning I try to start it and it shuts off. All gauges read fine, full tank of gas. As soon as I turn the key, the engine cranks over and less than a second the gauges crash to the left and dies. That d**n lock flashing in the dashboard. 6 hours later try to crank it over the same thing. So I get the truck towed to the dealer, and the service guy says it's the aftermarket alarm. They charged me $90.00 to remove it and place everything to orginal specs. I just don't see how a month later after the install of the alarm the Passlock crap would start to act up. Well got the truck back with a scratch on the tailgate, and as of today the freaking garbage lock on the dash lit up again!!!! Now WTF are they going to say since there is no alarm in there! Is there a way to disable the Passlock? I don't need the crap, since I also have lojack. I don't want this to happen when I'm at Glamis with a 10,500lb toyhauler connected!!!! Any help will be greatly appreciated.

why did they charge you? They obviously didnt install something right. Thats THEIR problem, not yours. Id get your money back.

there are modules you can install to make PASSLock compatible with aftermarket alarms/remote starts. If they are installed correctly PASSLock isnt a problem.

You wont say PASSLock sucks when you're parked next to a Ford and Dodge, and they get stolen and your truck is still parked there

They charged me because it wasn't something they installed so it was not covered by the warrenty. The alarm I puchased is the Clifford Matrix RSX 3.5 Can you give me more info on these modules for this type of alarm? I would like to reinstall it, but make sure my truck works fine. I just find it hard to believe that after a month with the alarm installed the Passlock is now acting up. A person would think that right after the install you would get problems from a improper install not a month after using it. The manual says that if the lock indicator lights up while you are driving that the passlock is in need of service and to take it to a dealer for repair. Am I wrong on this, or my just misunderstand the way this thing works? Thanks for the reply and help.

Worked at a Chevy dealer last summer. Those d**n aftermarket alarms were/are nothing but trouble. $90 is the cheapest removal I've ever heard of, must have been an easy one!

On edit: Who would want to steal a Furd or a Dodge???

Aftermarket alarms usually wait a few years before they start screwing things up royal. Actually it's the crappy work the installers are notorious for as they don't do anything right. You must have installed it or had it installed in the worse way. I hate having to repair cars with that stuff on it and it would have cost you more if I had done it. Also passlock will do more to prevent your truck from being stolen than the alarm would have. Have it fixed.

Not sure if the "security relearn" would have helped you in this situation or not. Do a search for it and you will see what im talking about. It may help out in a pinch, but it wont solve your problem long term.

PROCEDURE:

1.Insert key, attempt to start the vehicle and leave the key in the ON position.

In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.

2.When the Security light goes OFF, turn the ignition to the OFF position.

Leave ignition OFF for 20 Seconds.

3.Attempt to start the vehicle again and leave the key in the ON position.

In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.

4.Turn the ignition to the OFF position for 20 Seconds.

5.Attempt to start the vehicle again and leave the key in the ON position.

In some vehicles, the Battery and Security light will blink for several seconds, and then shut off. Then the Security light will then remain ON. Leave the ignition ON until the Security light goes OFF. This will take more than 5 mins.

6.Once this entire procedure has been completed (three times) your vehicle will start on the fourth attempt.

You also have Lojack installed???????????

Thats prob. another cause of your problems................

Have that disconnected also and see if it is the cause.

Lojack is only installed by their technicians. Not even the dealers install these. What I don't understand is other people have some of the same issues that I do with this Passlock even without an alarm installed. I think GM should stick to making, and improving their vehicles not trying to become a security company that can't get it right the first time. We should not have to be the guinne pigs. I'm just pissed that I would have to even consider doing that Passlock reset (no guantee it would work) on a $40,000.00+ truck.

I did not have a lowjack installed. I figure the OnStar IS my lowjack. Truck gets stolen you can call and they can notify the Police as to it's location and if need be cut the ignition..

sonjaab · June 19, 2006

FUNNY.........The ONLY time I see passlock or other NO start

problems on ANY of these GM truck forums is when folks have

ANY aftermarket gadget "cobbed" into their vehicles..........

I went thru this on my 97 Chevy..........Never again~

Your alarm guy obviously didn't do the install correctly. Passlock is very sensitive to slight voltage variations in various circuits, and a loose connection or such can wreak havoc with Passlock. LoJack guys are pros, doubtful that's causing the problem, but always a possibility.

Try a post over at www.the12volt.com, a forum for alarm/stereo installers.

FWIW, don't know whay you need an alarm anyway, between, Passlock and Onstar and LoJack, the only way they're gonna get the truck is on a flatbed anyway.

Frozen001 · June 19, 2006

The problem is most likely related to the AFTERMARKET alarm. Passlock works by sensing the current/voltage through a dedicated circuit. What is probably happening is that the circuit is now intermittent due to the alarm installer installing the bypass module, and then the dealer removing it. Believe me you are way better off having the dealer correct the blunder by the installer and throwing the aftermarket alarm in the trash. 90% of all of those alarms do nothing but cause problems.

If you need lo-jack + passlock + onstar +alarm you need to move to a lower crime area.

Well you guys are probably right. The problem is now I don't know if I can return the alarm. I'd hate to lose $420.00 on an alarm. Piece of mind is well worth it if I know when I turn on the ignition my truck will start in Glamis. Thanks for all the replys and insight. Wish I would have found this site sooner, instead of after the fact I had problems.

I wanted to install remote start in Wife's Burb. Called my good buddy who is service manager at GM dealership. He said don't do it. Any time you tap into the standard wiring / computer system on a late model vehicle you are asking for trouble. He said majority of electrical problems they see at dealership are result of aftermarket alarm / remote start / etc.

As previous poster said, On-Star can locate and shut down your vehicle if it is stolen.

MaximumOD · June 20, 2006

Why is it then the same dealers that tell you not to install an aftermarket alarm, also want to sell you an alarm at the time of purchase? Sounds to be a bit hypocritical, since gm doesn't make alarms. So what kind of alarms are these they sell that are not aftermarket? Or is it that they will sell you an alarm but as long as they install it? I'm not going to put mine back on, but just trying to understand the doublespeak.
