Inquired about Chrysler reprogramming my sentry key system

Basically I sent an email to Chrysler about reprogramming my sentry key system to match a 300M Special computer.........and this is the response I got back (I expected a response like "it's not possible")......but this is close enough :p

I have spoken with a number of different techs as well as our Parts Manager regarding your request. Unfortunately at this time I'm afraid I am unable to help. The serial code in the PCM (300M) will be coded to match the existing components in the original vehicle and I am unsure how it would react to programming (Remote Keyless Entry and other vehicle components) if it were transferred toanother vehicle (different model etc.) While I concede this may be possible, I am not sure how we could proceed on our end of things without incurring a large cost (of which I couldn't even begin to estimate) and I am still unable to guarantee our work would even accomplish what you are requesting. I apologize, I don't believe we will be able to help you with this. Should you have anymore questions or concerns, I would be happy to help anyway I can.

Best Regards,
Chris Newman

Anyone know if this IS possible? Would the keyless still work with a different computer? Can my OEM keys and transponder be recoded to match the new computer?

I just found this - so it would appear that it IS possible to do & and not necessarily by a DC dealer:

Chrysler Flash Procedure
Chrysler's flash procedure is sort of a cross between GM and Ford's procedures. First you go to the www.techauthority.com website and download their "benchtop Programmer" software to your PC. Then you download a huge pdf file ("J2534 Flash Availability") that lists all Chrysler PCMs and their software updates. Chrysler uses vehicle body codes to identify the PCM in addition to the VIN, and you need to use a scan tool to get the module ID from the vehicle. If the vehicle needs a update, you go back to the Chrysler website, pay their access fee, and download the new software to your PC. Then you transfer the software from the PC to a scan tool or J-2534 pass-through tool to install it in the vehicle.

Also note, many Chrysler PCMs require a re-initialization procedure after a flash. For more information about this, click here (requries Adobe Acrobat to open pdf file).

Here is a sample of the flash reprogram procedure a Chrysler dealer would use. This one happens to be for a recall Chrysler issued for 1999 California Dodge Ram Pickups and Vans with 5.9L engine ("Z" engine code in the 8th VIN position), automatic transmission and California emissions control system (code NAE). The OBD II catalyst monitor on these vehicles may not detect a catalyst failure so the PCM programming had to be revised to comply with California regulations.

The dealer accesses the latest software through the modem connection in the Mopar Diagnostic System, and feeds it through the DRB III scan tool into the vehicle's PCM via the OBD II connector. The process begins by turning the ignition key on (engine off) and allowing the scan tool to "auto connect" with the PCM. Once the lines of communication are open, the VIN is displayed on the scan tool. The technician can now press the "OK" button to proceed with the reflash procedure.

The first thing he does is select "Read Part Numbers From Vehicle" and click "Show Updates" on the MDS2. If somebody has already reflashed the PCM, the screen will say "Part number is up to date and does not require any new updates." The software number should be compared to the latest version to verify the numbers match just the same. If the PCM has not yet been updated, the technician clicks OK, selects the new software part number and clicks "Update Controller Software." From that point on, the process is automatic - but there is a hitch. During the flash reprogramming procedure, the PCM loses communication with other modules on the vehicle that may set a number of "false" trouble codes for the transmission module, ABS module, body control module, etc. This does not indicate a problem and the codes can be erased after the flash reprogramming procedure has been completed. The technician is also supposed to attach a label to the PCM with the reflash part number and date indicating the PCM has been reflashed.

Not Without Risk
So what happens if something goes wrong during a reflash procedure? Anyone who has ever experienced a crash while installing new software on a PC knows it can cause real problems. In some cases, the PCM may be so scrambled that it will not accept a reflash, which means you get to buy a new PCM!

Chrysler issued a TSB (18-32-98) that deals with how to recover from a flash reprogramming failure.

The bulletin says, "Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment may lock up during the procedure." Common causes of flash errors include poor cable connections between the PC, scan tool and vehicle, loss of power to the diagnostic equipment while the flash procedure is underway, turning off the vehicle ignition switch before the flash procedure is complete, unfamiliarity with the procedure (pushing the wrong buttons), or low vehicle battery voltage.

If the process crashes, recheck all the cable connections to assure good communications and reinitialize the flash procedure. In other words, if at first you don't succeed, try, try again. On the Chrysler applications, you may also have to identify which type of controller is on the vehicle (SBEC2, SBEC3, JTEC 96-98, JTEC+ 99, etc.) to get the system to accept the new programming. If you get an error message again, you probably selected the wrong controller type (try again!).

Doing your own flash reprogramming is not without risk. But for some shops it may be a more practical and profitable alternative to sending vehicles back to the dealer when a PCM needs to be updated or replaced.


Here is the site & it has a lot more info on reprogramming:

http://www.aa1car.com/library/2004/us10430.htm

Here is another place that sells the equipment:
http://161.58.194.170/J2534/index.html

It would seem to be a law that anyone can do it, not exclusive to a certain dealer.
However you must purchase the software from the manufacturer, either for long term or short term useage.

Not sure where you came up with all those part numbers, but the correct one is
4606 873AA (2002 high speed) & 4896 226AC (2003/4) high speed.

The one I can get will be the first one, from a 2002 car.
Retail price is $390.00 USD for either

Oh, those part numbers are PROGRAM part numbers........for the data, not the actual units. I'm still trying to figure out the easiest way to do this.......it'll all be figured out by tonight. I'm thinking that after talking to a few people here, the easiest way is the hardest way........getting all the parts from an '02 M Special donor car......and using 2 keys......one for the ignition, and one for everything else :(


....not gonna stop me though, I'm sick of my speedo reading high........it's only read correctly for a couple months in the last 3 years :(

OOOOOOOOOOOOOOOK, got some info from Dave "D76G12".

Apparently the PCM's are write ONCE PCM's.........NOT reprogramable. So my computer is TECHNICALLY the same computer a 300M Special uses, but isn't reprogrammable to act like a 300M Special PCM does.

Basically if I bought a new computer, give the dealer a VIN from an '02 Special.........have them download the software for THAT car.........and then upload it into my Intrepid, the car should basically take care of the rest.

Anyone ever autopsy one of the badboys too see what kind of chip is used to hold the info ? Many memory chips can be edited and rewritten. Also, it can probably be determined by their part number if they are in fact write once only, even they can be read and a new chip flashed with edited info , or possibly be replaced by a reflashable part.

Why use 2 keys? Use the ignition from your car, get new sentry keys cut for it(they'll be the same key as your existing one) and program the chips for the special's SKIM. Basically you'll be making a hybrid key. Cut to match your ignition and doors, programmed to match your new SKIM.

That's TRUE........


QUESTION........would I really NEED the ignition lock and the key? .......orrrrrr can I get the sentry key info from the skim so I can re-program my keys to match the new SKIM without having the key from the actual car?

When a PCM (SBEC) and the SKIM are replaced
at the same time perform the following steps in
order:
(1) Program the new PCM (SBEC)
(2) Program the new SKIM
(3) Replace all ignition keys and program them to
the new SKIM.



PROGRAMMING THE PCM (SBEC)
The SKIS Secret Key is an ID code that is unique
to each SKIM. This code is programmed and stored
in the SKIM, PCM and transponder chip (ignition
keys). When replacing the PCM it is necessary to
program the secret key into the new PCM using the
DRB III.(2) Use the DRB III and select THEFT ALARM,
SKIM then MISCELLANEOUS.
(3) Select PCM REPLACED (GAS ENGINE).
(4) Enter secured access mode by entering the
vehicle four-digit PIN.
(5) Select ENTER to update PCM VIN.


Depnding on where the pin is stored, you may need the 300 special pin # .

Ummmmmm, OK, so where the heck do you get the pin #??? I guess since I'm considering replacing both the PCM and the SKIM (will match each other), but reprogramming my keys to match them......I'll probably still need the pin # for the key programming?

Chrysler gets it from their database from the vin. I specifically asked for mine when I had a new key programmed. I wonder if you got the skim and keyheads for the 300 if that would work...or clash with the bcm because of the vin ?

EDIT: a quick look at the manual doesnt seem to show a vin or skim codes relating to the bcm.

And BTW..your keys are write once..they are good for YOUR skim and nothing else unless the existing skim codes can be transferred to another skim module.

$20 on eBay for a new generic blank Chrysler sentry key shipped to my house.



.......sooooooooo, let's summarize here:

If I get:

Junkyard 300M Special PCM
Junkyard SKIM module from the same 300M Special
VIN # from the same 300M Special
at least 1 blank uncut Sentry key


..........I can swap the PCM and SKIM modules, have the key cut to my own Intrepid's cut, and have the key programmed to the VIN # of the 300M Special.

..........I should be good to go?

I don't believe it's that simple. No way will a dealer program a key to a vin number of any car other than your own, if they even can with the DRB III.

Do you have SKIM now?

Re-read my post above on how it is done.
It is not "necessarily" a one shot deal, the proceedure is outlined above & more info is on that site.
As well, all the 3.5 PCMs are basically the same - sort of like all Intrepids are the same. The PCM's are 380 USD, (slightly higher in Canada!!!) regardless of programming.
They have different programming depending on each vehicle's parameters.
The dealer doesn't need any VIN if the tech knows what he is doing.
He basically accesses the PCM and uploads the parameters for the M Special to the PCM.
There are a lot that can also be changed , such as pinion, tire/wheel sizes, shift points, SPsteering enabled. Problem is that most service depts don't know how, &/or don't want to fool with it, plus they are going to charge you $85+ per hour to do it.
