Dick,
Actually I feel this is an appropriate thread. Anybody searching for key programming in the future and finding this thread will not know to go to the DAD topic thread. This DAD information directly applies to key programming. The key program question getting to the DAD topic thread is another issue. I deleted my post here for you though. Hope this does some good. AP/vic

I agree as well - I'm part of another discussion group of a completely different topic - on that "board", "tags" are enabled. They make searching MUCH easier as long as posters add relevant tags - Is this possible here?

Thank you nebep for all the info...! Do you have any fears that when you're trying to key your two Sprinters alike, you may wind up unable to start either ?!

The aftermarket type key you mention, I'd like one of those for a third spare. I'm really after/want one oem spare.
Where are you located? If you can re-key a 97 Passat ignition cylinder,(I have pics) lmk...I'll ship it to you. I'm tired of two keys for one car due to dealer incompetence.

or put in another way,
If the fob looks to be exactly the same type with the same number and placement of buttons/led will it work?
???

Do all the fobs have a separate/different FCC ID#? I never looked at my two originals to see if they were the same FCC ID. Model year specific, fob specific? Interchangeable? Would an '05 fob work for an '03

Default Re: Key Programming

ScottMC - I have a plan A and plan B:

A: Identify/read the microcontroller that contains Immobilizer data from the '04 and the '02. Save both files. Verify them both. Write the '04 immo. file to the proper microcontroller in the '02. At this point the keys which start the '04 will start the '02 also. On the mechanical side of the house, I'll either rekey the locks myself, (I have a kit for older Mercedes which use the same key that may work), or order new cylinders for the '04 and put them in the '02. As far as the ignition goes, I might have to purchase a new ignition cylinder for the '04. I'm not sure if the ignition lock cylinder is servicable or not. (Servicable = can take it apart and put it back together without being able to tell this was done - If it's not, I'll just go the "buy one for the '04" route.) Once this is all complete, the keys for the '04 also operate the '02. Since I have cloning equipment for the chip, I'll be able to make as many keys as I want, which will work on both trucks.

(The purpose of using the '04 is that it has central locking/remote keys. So, I want to maintain control of that functionality for that one - the '02 is a "poor boyz" truck - no power anything...no remote key...I'm not planning on adding those functions to that truck, but, I do want to keep them alive on the '04)

(All this microcontroller talk is based on what I'm able to do with other vehicles. From what I gather, I don't see why this wouldn't work. There may be some reprogramming needed between the cluster and ECU - I'll probably be going after Doktor A to see what he knows about this before proceeding too far. Not 100% sure - these are details I'll be working to find out BEFORE starting down this path at all.)

B: I have a DRB-II with all the things needed for servicing the T1N. - I should be able to accomplish the same thing if plan A doesn't work out.

If I write the data from the '04 to the '02 and the truck doesn't start, then, I'll just need to re-write the data for the '02 back to the controller, then I'll be able to drive the truck.

I'm personally rooting for plan A...

This will definitely be a learning experience...

To get an OEM key - you'd need to order it through the dealer. I'm not sure if Jim (ekeys4cars) has a DRB and the connections to get the programming done or not - worth asking him. Also, it would be worth asking him about your Passat Ignition too - he's much closer to you than I, he's a stellar fella too - I've known him a good while. I promise he'll steer you right.

Arrow Re: Key Programming

Information I've received from Sprintguy (Carl) in conversation yesterday, (simplified, I'm sure he'd put it better.) says that the van's ecu recognizes the key, so you need to tell the van, this key is ok via a ridiculous process. We seem to think the `05 key would work on my `03 once programmed. I do have the central locking, one of my favorite features.

Default Re: Key Programming

Yeh,

This is my thought process, based on what I know of many other vehicles:

the immo. module is reponsible for reading the chip data from the key and "signalling" the ECU that the key is ok, and authorized. From there, the ECU performs appropriately based on this "trigger" that everything with the key IS or IS NOT ok. If NOT ok, the ECU does stuff like, cut fuel, keep power from getting to the starter(which I assume wouldn't be the case in the sprinter anyway), things like this...

That communication link between the two is what I'm expecting will "break" when I put the immo. data from the '04 into the '02 - and another reason I'll save the original file for the '02 if I can't get the ECU/IMMO synced back up for some reason. because - the data will expect to be synced up to the ECU in the '04 - not the ECU in the '02...So, if I can't get them synced up, I'll plop the 02 immo data back on, that data will be "familiar" with the ECU of the '02, and the truck will be back in its original state and driveable...

from there - It'll be time to just suck it up and code the keys from the '04 to the '02 once everything is mechanically correct and call it a day.

...without doubt...still IMPORTANT questions to answer before trying this...In the end, it will work, there are just a couple of questions that need answers, and I know where I can go to get those answers, so, it's all good!

It'll be an interesting process...

..and i agree with that. What i -should- have written would have been:
ALSO ask (in the DAD thread)

..so that DAD followers would notice the question.

My -understanding- of the issue agrees with Scott Mc: you can introduce a new -starter- key to the Sprinter by having the other keys available to "certify" that the new one is friendly.
I haven't noticed any screens/procedures in the DAD that involve (or hint at) accepting a new key.

(riffles through DAD menus....)
DAD has no "set SKREEM" screens/menus, beyond "clear errors".

That was my disappointed discovery, too. I was hoping for diagnostic procedures for the SKREEM or CTM to solve my keyless entry blues.

Otherwise, it looks like a very impressive set of tools. I've not connected mine to my vehicle yet, but I installed the software on an XP desktop and read the user PDF.

The DAD has a data stream menu for the SKREEM module. For your particular remote key issues however it regretfully does not offer a RKE/CTM data stream. Doktor A
