I have a 1999 Pontiac Grand Prix GT with a bulldog remote starter. To the best of my knowledge my car has Passlock II security system so that's the instructions I'm following to install the DEI 555L bypass module. I've hooked it all up to the correct wires, except I'm not sure what yellow wire is the resistance wire. There are numerous yellow wires. I've tried 3 of them with no luck. The unit does not bypass anything as it's hooked up now. Either the unit isn't learing the code, or i don't have the right resistance wire connected, which I'm pretty sure is the problem. The wires i have tried are, 1. Bright Yellow, 2. Light Yellow, 3. Yellow with Black stripe. Does anyone know where this wire is? Maybe it's not even yellow, I don't know. Any help would be appreciated Thanks.

99 grandprix doesn't use a 555L for bypass
you need a 555G

Well it has factory anti-theft system so it obviously has security that needs to be bypassed. I however did not know I need the 555G :( I can not find any information for this car's factory system but i figured it had passlock II so i'd use the 555L. Extreme1, how did u find out which bypass I need? Do you have experience with '99 Grand Prix cuz i could use some help if you have. I hope i don't have to buy another bypass module. I already have a bulldog #791, and now this DEI 555L. What's the main difference in the 555L versus 555G? Thanks for the information.

why do you assume it has a factory security just curious. also it looks like you could also use a 555u if you did in fact have passkey 3. remember with the 555u you must sacrifice a key.

It has Remote Keyless Entry W/Factory Anti-Theft System. I have the dealership window sheet with all the specs and features it has. It lists "Theft Deterrent System". I know it's not one of those transponder ones cuz none of the keys I have have that little chip on them. I just found a site that lists a 1999 Grand Prix having VATS Key Anti-Theft system. I originally tried hooking up the bulldog #791 unit with the VATS instructions. Maybe I'll try that again and see if I can get it working this time. I really don't want to buy another bypass module. :(

that vehicle does not need a 555l, It may possibly have VATS on it. the way to tell is if on the metal part of you key, you have a little black "chip" on either side. this is a resistance based immobilizer system. this should explain why you can't find the right wire.

see now VATS is just a resistor pellet imbedded in the keyshaft.
555L doesn't work well for vats, I use a PL2002 for vats.

Is there a reliable/incluisive chart out there to see who has Vats, transponder /passkey/Lock, I, II, III, ..... Vats was old, and the resistor was in plain view on the shank, but the now they're hidden right? For instance I've got a '97 Grand Prix. No factory Theft System. My manual mentions Theft Deterrent (but only for those that were optioned). I don't think I have any of these. One chart agrees, but another says "transponder".

Some hints: Red "Theft" light on dash (briefly after start) = Passlock I Yellow "Theft" light on dash (briefly after start) = Passlock II "PK3" written on Key = transponder system (likely for 2003+) Vats = resistor on key shank.

I've looked for many charts about security systems, but none of them list pontiac grand prix from 97-99 at all which makes this whole thing all the more frustating. They always list from 2000-2004, or 1992-1996. That was until I found this chart at crimestoppers, https://www.logjamelectronics.com/logjam/crimmodapp.html I don't know how reliable it is but it's the only one that's listed my year. U can see it lists grand prix 1994-1999 with VATS, so I attempted to use VATS instructions for the #791 bypass module. Needless to say it didn't, I even tried the Transponder (PK3) setup because according to the wiring diagram I downloaded for my car it said under factory anti-theft "Transponder PK3". This method did not work either. And none of the keys have a chip or say PK3 on them at all. So I have given up on trying to do this myself. Their is a major lack of knowledge with this make, model and year of car. I think i'm going to have to pay someone to look at it and hook up the right bypass module professionally.

Well if you're throwing in the towel, then you owe us 5 cents each for the swell advice (I get 15 cents for posting my reply three times) Actually the right way is to just take apart the ignition switch. Look for a couple of thin guage wires. They should be (white w/BLK trace) or (Violet w/YLW trace). Some were Both YLW or Both WHT. The givaway though I think is the small gauge. The 555U (Universal) might work best for this situation since using a spare key assures you it will work, regardless of the system. Just get a spare key from Mr. Dealer, (test it first!) and hook it in.

i have checked all my sources and they tell me that vehicle doesnt have any factory anti-theft for that model year.... it does have a factory alarm, but no anti-theft to worry about..... ------------- Kevin Gerry

Thanks for checking, I have no sources, other than this fine forum. I know it has Remote Keyless Entry W/Factory System of some kind, so it could be alarm as you say. But it needs to be bypassed none the less, cuz it still goes off everytime I try to remotely start it. I just don't know what else to try other than buying another bypass. I just got sick of messing with the whole thing. I'll have to do more searching for bypass modules. Thanks for the replies.

Update: I sent an email to DEI tech support asking them what unit of theirs I would need to solve my problem. Tech support confirmed the fact that a 1999 Pontiac Grand Prix does not have any factory immobilizer anti-theft system. Therefore no DEI module was needed. After explaining to him that I have a bulldog remote starter that works without the system being armed, he told me chances are that the remote starter unit wasn't interfaced with the factory keyless entry system, and he sent me a wiring diagram, https://www.the12volt.com/installbay/detail.asp?info=alarm&year=1999&make=Pontiac&model=Grand%20Prix&ID=18793&type=Alarm ,showing which wire was the factory disarm wire. Sure enough the remote starter wasn't connected to it, so I connected the "factory alarm shutdown", RED / black wire, coming from the remote starter into the ORANGE / black, disarm wire, on the Driver's Kick Panel 32 pin harness, pin #5. And that was it! Now I can arm the system and have it remote start without the horn going off. One simple wire that was overlooked by the installer of the unit costed me a lot of time and some money, but I hope this information will help anyone else out there with this same problem. Thank you all for your replies.

kinda nice of DEI's tech support to spend the time with you when you purchased a BullDog brand starter........ dont you think????

After reading all this, I think I'm in the same boat as far as OEM security systems. I have a 02 Astro that has OEM keyless entry that I am about to install a RS system and was assuming I needed a 555L because my Chevy owner's manual says the vehicle has the "Passlock" theft deterrent system. I was suspicious of this because the keys have no appearance of having a chip, although they could have something in the plastic part. Is there a surefire method to determine what, if any, system the vehicle has? How would I be able to get a diagram as in the previous post, to find out for sure? Thanks, Joe

Your van DOES have PASS 2 It's in the Ign. Cylinder.
I use OMEGA DB-PLDATA simple to install and hooks in to DATA wire

Does that mean the key has a resistor in the plastic part and by data wire, do you mean at the ECU in the driver's kick panel where the OEM KL hooks up? Thanks, Joe

NO your key has nothing in it
The Pass 2 system uses a Hall Effect Sensor that sends the resistance code to the Passlock Module when the key is turned
