Reading Pin Code on 2001-2007 Dodge Caravans

[MaximumMini]

Anyone know of a Hex to Dodge'/Chrysler Pin Code conversion chart?
I downloaded the EEPROM contents and I know which bits are the Pin Code, but I still need the Hex conversion table for these vehicles.
I have the chart for 1996-2000 Caravans, but not the 2001-2007s.

Not really sure if Autel, Lonsdor or XHorse will pull the pin on these older vehicles.
The RKE isn't working and I'm trying to get it all back working.
The Immobilizer does work so the key is the correct one and seems to have the correct code, just no RKE.
Could always be a wiring or BCM issue as well (sigh).

send me the eeprom dump and I can decode it, There is a specific sequence you look for in the dump. pin is bit swapped in that sequence.

I really appreciate your offer. Thanks!
But...give a man a fish....you feed him for a day, teach a man to fish and you feed him for life
Just some confucious stuff there. haha.

I believe the bits I want are at location 7 and 8.
But...as you probably know, all Dodges and all Chryslers (AFAIK) do not use the exact same location for the pin code on all models.
On the Caravans I believe a 1F 00 marks the position of the pin code for 1996-2000, then bits 7 and 8 for 2001-2007.
If you care to confirm that it would be great.

I still would need the Chrysler / Dodge Hex to Pin Code chart to determine the actual pin code. On some you can directly see the actual code that you have to know how to reverse because it's encrypted, but on others you need a conversion chart. If that's not correct please let me know.

It's so easy to throw a bunch of cash at the problem and load up on tech gadgets (shotgun approach), but I'd like to become a bit fluent in the process to get there without it as much as possible first.

do you do this for a living or hobby?

You shouldn't need a PIN just to program a RKE fob on a RS van?
The earlier ones had separate Sentry Key
Later models had the remote head key

What particular van are you working on?

AlfaOBD can't pull the PIN (even tho I wonder if you need it)?
Is it high trim or optioned with VTSS?
Chrysler Pin Puller app can do MY05+ allegedly

Hello Michaelluscher!

This is a 2005 Dodge Grand Caravan.
It is a base model trim but does have VTSS which I cannot disarm so every time I lock the car I have to be very fast to jump in and place the key in the ignition and switch it on to re enter the vehicle and deactivate the VTSS. Obviously, the immobilizer works, but not RKE. It has a SKREEM AF295. I need to do some electrical diagnostics to see if the SKREEM is bad or if there's a BCM or physical wire problem.

I recently picked up a spare SKREEM that matches so I may push the binary code from the original into this one and see if it works.
I have the Binary file pulled from the EEPROM. Just don't have the conversion chart from Hex to Pin code.

I do have an XTool D8, which is absolutely useless for the job. To be honesty, the D8 seems to be just a high priced basic and overly embellished OBDII scanner that has really disappointed me.

Does the XTool have the menu option for PIN pulling or to program if you got the code from somewhere else?

I didn't keep my XTool, glad I returned it
If you go to your Chrysler parts counter with proof of ownership and ask nicely, they should give you the PIN
Or there's shady eBay sellers and websites who can also assist

Is this a PIN issue, or a tool issue
How many keys do you have that can start it?

Man you made a good call returning that XFool thing
I have a fleet of older caravans and all but one runs like new.
They are my forever keepers. But I only have one key fob each, for ALL of them and I want backups for all of them.
One of my 1999's has no response whatsoever to the FOB, but it does need the fob for the immobilizer. My 2005 has no response at all to the FOB but it also needs the Fob for the immobilizer. My 2006 is not working but I think the FOB doesn't work for that one either (but again, it needs the Fob for the immobilizer so lots of Caravan Key Fob problems. An I absolutely HATE taking anything to any shop.
I have the build sheets for all of these and they do have RKE and VTSS on all of them. I think the 1999 needs the BCM VIN changed because I believe years ago I changed the BCM to disable the VTSS.

The XTool does have all the lingo for pin reading, key duplicating etc...problem is....every single time it takes me through all the steps only to get to the finish line and tell me that there's been a communications failure or I need to see a dealer (imagine that...you spend that kind of money on a tool and the best it can do is tell you to take the vehicle to dealership after all !!)

I'm going to buy a few real tools like the VVI Key Tool Max Pro and the Lonsdor and XHorse and if I can't get it done with that THEN I'll try a dealership since I have clear titles for all of them. By the time I get all that stuff bought and figured out, heck, I might as well become an automotive locksmith

On a non-can chrysler the pin code cannot be pulled via OBD,

Haven't tried pulling them that way.
Only via Micropod2 and Witech Chrysler emulator. (And XTool).
No joy on any route so far.

But I can pull the EEPROM code. Just need the right Hex to Pin Code charts.
Otherwise, I'm going to start trying from 0000 and work my way to 9999. Hey, there's only 10,000 possibilities

This companies software claims it can do it

But you're fighting an uphill battle, go try and play nice with your Chrysler parts counter person
It might cost you some marked up oil filters, but it'll save your sanity

I appreciate your suggestions. But I'm already in too deep.

I have 4 Dodge Caravans and I've promised all 4 of them that they will never be subjected to Dealership torture.
I HAVE to get this process down pat. And I will. Getting the pin codes is probably the easiest part. There could be issues with the modules themselves or the communications networks.

3 of them have remote/RKE/VTSS issues.
If I need a dealership for ANY reason, I'm sunk.
I've been looking into Andromeda Research (the company you mentioned above)
What I'm doing right now is studying the entire architecture of the SKIM, SKREEM, PCI-Bus (on the 2005 and 2006..the 1999's use CCD-Bus) and wiring systems to get a comprehensive foundation on exactly how everything works and why.

I'm confident that with my background in electronics, my knowledge of these vehicles, the right tools and perseverance I'll master these issues. These are my forever vehicles. It's a battle worth fighting imo
