Printer Friendly Forum Posts - DEI 555l , 2001 Alero

I know most of you are sick of hearing this question, but I've read until my eyes were bleeding and can't find the answer I'm looking for.

My question...I have a 2001 Alero with Passlock II system. I want to bypass it and I do NOT have or want a remote start system. Will the DEI 555l module work on a system without a remote start. Could you please talk in elementary terms as well as I'm no mechanic or electronics guru. Could you also give a description of the installation that needs to be done?

Thanks very much

Joe

The 555I is for Honda/Acura.........Not sure that will code

Shouldn't U use: 556LW or 555LW or 555T or ...Can use the 457GW to bypass the Passlock II

Either way U will need to Ground BLUE wire on unit & Learn Key

Ok, looks like I need to figure out which one to get but, are there instructions that come with the bypass to tell me how to Ground Blue wire on unit and learn key? And will they work without a remote start?

Thanks for the quick replies

May I ask why you are trying to circumvent a theft deterent feature of the vehicle? Are you having problems with the Passlock system?

"May I ask why you are trying to circumvent a theft deterent feature of the vehicle? Are you having problems with the Passlock system?"

Yes, it's my 7 month pregnant wifes car. It will not start about once a week and you have to wait 10 minutes for it to start, we really just can't afford for this to happen in case of a baby emergency.

Do you need a bypass just for a alarm no remote start???

Yes no remote start, don't have one and don't want one.

iskidoo,

So that device will work to bypass the passlock with NO remote start system?

Thanks folks for your help

Do you have another suggestion?

Thanks

It's a passlock II on an Alero, the security light blinks and I have to wait ten minutes for it to reset....why wouldn't a bypass work again, what's a keyless bypass

e reason that is happening is that it does not see that you have the right key in the ign. It may be the key, the cpu or a ign. switch. A keyless bypass is where you don't need a key in the bypass to work.

well...if the correct key is in the ignition then it sends the correct resistance back to the passlock II system that allows the fuel pump to run and the car to start. With a bypass I was hoping to learn that resistance and bypass the "send back" feature of the passlock II, hence always feeding the passlock to the correct code to start.

This is the problem with using the search feature, there are lots of articles on this subject and a whole lot of negative posts about how "this and that" will not work, but no solutions....please, try to limit responses to solution thoughts and not negative mumbojumbo. If you've ever noticed before the person with the "this and that" will not work also doesn't have a solution

I disagree...perhaps we can agree to disagree. iskidoo!! where are you?

We don't really know if the bypass will fix your particular problem. Usually, people are just trying to temporarily bypass the key to remote start the vehicle but their Passlock 2 system is working just like it's designed to. So given that your whole Passlock system has an intermittent problem you might be wasting your money and time with the bypass. But if you want to try it then it involves about 4 wires on the unit and then some initial programming using the existing working key.

~ Constant Ground (vehicle chassis)
~ Constant +12 volts
~ a ground while starting
~ data wire (PIN#2 OF OBDII DIAGNOSTIC CONNECTOR)

Most remote starters supply a ground out when starting that feeds the 3rd input. Where you are not using a remote starter, you may have to add some kind of relay that inverts your +12volt starter wire into a negative (ground) to feed your bypass unit.

After doing all that if you still have the issue then your going to probably have to pay a visit to the dealer to get the system fixed. But without knowing exactly what piece of the Passlock System is causing the intermittent problem, it's hard to give you a viable solution. I know how to get around the Passlock system but I don't know how to repair it. You may want to try some auto mechanic sites to see what those guys have to say. Good luck though.

Ok then, I have a couple questions...

do you need to stick the key in the ignition before you start to drive if you use a remote start unit? I'm just curious if you remote start the car, then stick the key in it to drive will the passlock reject the key and shut down the car?

I'm pretty sure my problem is the ignition lock.

Once the vehicle is remotely started, you get in put the key in turn the ignition to on and then go. The Passlock will not reinitialize when you put the key in if it's already running, no.

If you press the brake though before turning the key on you will have to restart it with the key. The brake shuts down the remote start unit so the key takes over after you press it.

so after remote starting with the bypass, the passlock system will not care about the key you put in the ignition and turn to on, it will still run. Ok...

Let's say I put in the RS and bypass kit correctly and the bypass learns the code for the first time. Then I stop using the RS and start starting the car by the key again(because the RS is only there for emergencies). Then the passlock doesn't recognize my key one day. Will I be able to start the car using the RS that has the correct code that's stored in the bypass? Will the bypass lose its original configuration by using the key to start the car? How often does the bypass relearn? and can it relearn at the exact time that it shouldn't relearn, which is when the passlock isn't working with the key?

Slowly but surely I'm understanding

Thanks and sorry for being confusing and repititous

Joe

Once the bypass has learned the code it shouldn't need to be reprogrammed and shouldn't by accident. If your Passlock goes into tamper mode it will lock itself out for 10 minutes no matter what. You can't get around it even if you use the bypass with the correct code. This is by design to thwart would be thieves that try to use a few different key codes. It's not going to let the wrong code happen more than a few times without going into tamper. Not too many smash and grab thieves will sit there for 10 minutes to wait it out and try again.

Well, I just ordered DEI 561R RS and DEI 555l bypass. I hope this fixes my problem.

It shouldn't go into tamper mode with the 555l sending the same correct code everytime right?

Thanks for your help

Joe

Jeez.... wish I would have seen this sooner....

Okay. You could use the 555L to permanently bypass the passlock system. The 555L learns constantly, but once it learns the car once,it is generally good to go. To wire it up without worrying about any switches to flip or anything:

red- 12V constant
pink- ignition
Black- Passlock Ground
BLACK / YELLOW- Passlock resistance car side
Yellow- PL Key side
Blue/black- Take it to the light green keysense wire. It will turn the 555L on as soon as a key is inserted.

Of course, you COULD always actually take the car to the stealership and get the problem corrected properly. Probably the key cylnder, and it will probably be covered under a warranty or one of GM's little "secret recall" campaign. (We won't send out any letters, but we will sit on it until we get too many customer problems, and then fix them) There has been a lot of key cylnder problems in these parts lately, and they have been getting covered. You could also search your car on a TSB site like ALLData.com to give yourself some ammunition by actually knowing which TSB # applies to your problem.... they like that.... they are usually more interested in taking your money than looking at their service bulletins to see if it is covered....

and that's it, I will not have this passlock problem anymore after this fix?

I'm going to check for TSBs now

Thanks!

well alldata.com cost 25 bucks so that's out. I got an email from the place where I ordered the DEIs from shortly after I made the order and they said I needed a few more parts to make the door locks and trunck work so I cancelled the order all together until I got my shhh together, glad I did if all I need is a DEI 555l.......if that's the case?

I found it no problemo.... for free.....

Try here:

Like I said..... PLII problems are more common than you may think. Pile of bulletins on that car (I just picked a 2001 3.4L off hand, but you will get the drift) There is one for intermittant no crank/no start.... seems to fit the bill. If you can get it fixed properly under warranty, then why not?

Ah, and just for fun:
My own car

I ran my own car for comparison.....

I've been sick lately, sorry I won't be on much.

Do you have subscriptions and are already logged in? Because when I try clicking on the service bulletins, they want 24.95 to view them. Maybe that's what Joe was reffering to.

that is what I am referring to

No subscription.... you can look up the entire listing on any make/model/year for free.... $25 gets you the detailed buletins themselves. Armed with the actual bulletin number, you can head into the dealer, and give them the number as a nice surprise when they hand you a bill.

heck all that talk about different keys and the keys don't matter at all in the Passlock 2 system and Passlock 1 for that matter

the resistors for the Passlock system are built into the ign. switch and not the key on these particular systems

you can cut any key you want and it doesn't matter one bit so..................

as far as your problem I would go to a dealer and get it diagnosed b/c it's either the ign. switch /wiring to and from/ or the PCM

you may not like this but the bypass is not a good idea b/c especially if you're not familiar(i'm not saying you're not but i'm just assuming) w/ remote starts and stuff of that nature you're just asking for more trouble in the future

hope this steers you in the right direction

thanx
