Robbed Again!

[mistermike]

For the second time, my home has been broken into, and my EFI Live laptop stolen (along with much other stuff). The worst part is that they got into the cupbord where I keep all my extra keys, and they not only now have duplicates of my house and other car keys, they stole BOTH keys for my GTO.

Here's the question, if anyone is particularly well versed in BCM's and related systems on a 2004 GTO, equivalent to VY Monaro.
Obviously, new keys and reprogramming of the lock cylinders will be required.

A friend parting out a wreck will sell me steering column, BCM, radio, and 2 keys from the same car. I will still have to have the door lock cylinder reprogrammed. Hopefully I can find someone in the States who can do this. If not, I may be mailing my cyl / key to Oz LOL.

Obviously, the BCM will be happy with the keys and radio, but there seems to be some question of whether a BCM can be transferred to a car with a different VIN / ECM. Some are saying no, others are saying 2004 only. I'd hate to have to buy a blank BCM and pay the dealer to link it.

Also, for my own knowledge. There are 2 matchups that have to be satisfied with the keys. The RF codes and frequencies for the remote door and trunk unlock I know live in the BCM, but what about the codes transmitted by the chip in the key through the ignition for starting the car? Is this a BCM-key communication as well, or is this info transmitted to the ECM or some other module I'm not familiar with?

What do people who just have to replace key fobs do?

I'm sorry to hear that Mike.

I believe the owners manual will have the procedure to program a new key fob. If not, you could probably find the procedure on the www or sweet talk the dealer into programing it for you.

Have you considered adopting a two headed dog as the new family pet? With a head on each end, they create no bio-waste and are quite protective of the home :D

Here's what my service manual has for the BCM:

Service Programming System (SPS)
For step by step programming instructions, please refer to the techline information system (TIS) terminal.
Review the information below to ensure proper programming protocol.

Important
DO NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customers concern.
It is essential that the Tech 2 and the TIS terminal are both equipped with the latest software before performing SPS.
Some modules will require additional programming/setup events performed before or after programming.
Review the appropriate service information for these procedures.

Important
Once the PCM has been programmed it must be security linked to the body control module (BCM) and the Powertrain Interface Module (PIM). Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System

Ensure the following conditions are met before programming a control module:
Vehicle system voltage
There is not a charging system concern. All charging system concerns must be repaired before programming a control module.
Battery voltage is greater than 12 volts but less than 16 volts. The battery must be charged before programming the control module if the battery voltage is low.
A battery charger is NOT connected to the vehicles battery. Incorrect system voltage or voltage fluctuations from a battery charger, may cause programming failure or control module damage.
Turn OFF or disable any system that may put a load on the vehicles battery, such as the following components:
Twilight sentinel
Interior lights
Daytime running lights (DRL)--Applying the parking brake, on most vehicles, disables the DRL system. Refer to the Owners manual.
Heating, ventilation, and air conditioning (HVAC) systems
Engine cooling fans, radio, etc.
The ignition switch must be in the proper position. The Tech 2 prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.
Make certain all tool connections are secure, including the following components and circuits:
The control module Serial Data Link Tester
The RS-232 communication cable port
The connection at the data link connector (DLC)
The voltage supply circuits
DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. Attempt to reprogram the control module. If the control module cannot be programmed, replace the control module.

A little more info on Key Fobs:

BCM Replacement Procedures - kw code control entry Fob key keyless lock module number pin program radio remote RKE security TechII #PIC3370 - (Feb 7, 2005)
BCM Replacement Procedures
.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.
Condition/Concern:
After Body Control module replacement, the BCM security code does not function or cannot be located, key Fobs cannot be programmed to the new BCM, and/or the radio reads loc.
.
Recommendation/Instructions:
The GTO is supplied with a security card with all the security codes and key codes. When replacing a BCM, the new 6 digit security code is attached to the new BCM. The original security code is no longer operational with the new BCM. Write the new security code in the owners file and give a copy to the owner of the vehicle. The early security codes where tapped to the BCM with scotched tape. The current BCM security code is attached to the BCM on white label that measure 1 inch wide by 2 inches in length. The label does not have a bar code.
When replacing the BCM, new key Fobs need to be ordered. The original key Fobs will only operate with the original BCM. The key Fobs are write protected to the BCM that the Fobs are programmed to. The key Fobs can not be programmed to any other BCM. When programming a new BCM start by programming the new key Fobs first. Next link the BCM to PIM. Refer to SI Document 1379493 for link procedures. If security card is needed, refer to PI AIC3082A. After replacing the BCM, the radio may display loc. The radio 4 digit pin number is located on the security card or can be accessed through the Tech 2. Refer to SI Document 1349190 to enter the pin into the radio.
.
Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
Models:
(2004-2005 Pontiac GTO)

[mistermike]

Thanks a million. Is this info from the GTO service manual? My other stolen laptop contained the GM Service info software. I'm temporarily up the creek without a paddle.

[TAQuickness]

yes sir it is - specifically an '04 goat. PM sent...

[joecar]

Mike, sorry to hear that, hopefully they will get caught soon.

[dfe1]

Mike- sorry to hear about the break-in. If this is the second time, there's probably a good chance word has circulated amongst the low lifes that you have good stuff. I think you need to seriously consider an alarm system if you don't have one and a better system if you do.

As for your GTO, rather than go to all the trouble of re-keying it, why don't you just hook up a disabler? All you have to do is hide a switch somewhere and kill power to the PCM. It will never start unless they find the switch., and with a little creative thinking, they never will. You could also use the valet mode in a COS and set the rpm disable very low.

If you'd like some specifics, PM me.

Note-- To the first Administrator who sees this-- Since the thieves know that Mike has EFILive, there's a possibility they'll visit the forum to find out specifics about Mike's GTO. How about moving this thread to the restricted area.

[ScarabEpic22]

Im with dfe, lets no make their jobs any easier, ehh?

And Mike, sorry to hear about this. Once is bad, twice is horrible. Hope everything works out soon.

Mike, you will need a new BCM and Keys.
The keys are married to the BCM.
The BCM is then married to the PIM.
The PIM is then married to the PCM.

Not all need to be replaced if something goes bad. So if you change your PCM there is no need for new keys as an example.
I think it might be possible to marry the BCM to a new set of keys but I don't think that erases the previous keys (It can store 4 or 6 codes from memory) so you are better off being safe and getting another BCM.

The dealer will need to fit the new BCM and keys then marry those, then the new BCM will need to be married to the PIM. That should be it.

The worst part is the keys are worth maybe $30 at best to the dealer......check the over the counter price :eek: . Over $100 here last time I looked. And yes, armed with a hammer and a roll of tape you can change out the batteries on the remotes.

Cheers,
Ross

Mike moved it back for you. If there is any info in this thread you'd rather not have publicly available, let me know.

Thanks, Ross. I was kind of hoping you might chime in with your computer knowledge.

I have one fellow parting out a wreck who will sell me 2 keys, matching BCM, and column and even swap radios if needed for a very fair price. A local salvage yard will sell me column, matching keys and BCM, and also the door lock cylinder for $125 more. I guess it boils down to how much I might get hosed to have my door lock cylinder reprogrammed for a different key.

There seems to be some controversy as to whether you can take a BCM that was already linked to a ECM / PIM and re-link it in a different car. A shop foreman at a Pontiac dealer seems to think that BCM's are permanently VIN locked once they're linked up. The fellow at the salvage yard says it will work with a 2004, but not the later CAN bus BCM's. I guess I should be prepared to buy a virgin BCM if I have to.

[Cougar281]

What kind of anti-theft dies the car use? My mothers olds has PK3, and IIRC (which I might not), when you program a new key, you need to have all the keys available because it wipes out the programmed ones... Could be wrong though.

Durn it, Mike! That's what I told you a couple days ago on another forum - for the "remote", get a new BCM and new keys and you're golden. (OK, I didn't go into detail, granted...)

Oh, I know that will work, but I'm trying to see if I can re use another BCM and save the $230 plus labor. Since I have to change the locks so the thieves can't open my doors with the old key, the package of keys, column, door lock from the salvage yard makes the most economic sense.

So are you thinking salvage keys, column cylinder, door cylinder and BCM from one '04 GTO? That would certainly do the trick, I think. Also, it sounds like salvage keys & cylinders from one GTO plus a BCM from a different source might work, assuming you can associate a remote with the BCM.

Really sux about your Goat, BTW. These cars seem to have taken on a surprisingly emotional role for an unusual number of owners, I think - myself included. Part of it, of course, is the heart put into them by their Aussie creators.

Regarding your twin-screw: I seriously waited since long before you had yours running, back when you were still working on components. Less than a month ago, I bought a heads & cam package but what I really wanted was your setup. :(
