New SKREEM pricing make me want to Scream!!
 

Whiskey Tango Foxtrot. What happened?

Re: New SREEM pricing make me want to Scream!!
 

Go look at the price of a key now.. Mercedes has shafted us all..

Re: New SREEM pricing make me want to Scream!!
 

How much is a key now?

Dave, any cars that I could afford have always been liabilities, I've never considered them assets.:)

Re: New SREEM pricing make me want to Scream!!
 

Yes but at what point can you no longer afford to drive them?

Re: New SREEM pricing make me want to Scream!!
 

As long as the manual part of the key works I'll live without the buttons if need be.

Re: New SREEM pricing make me want to Scream!!
 

I was thinking about picking up a new project SRT6, but the updated pricing for the key and skreem have me a little apprehensive as I think one or both could be the problem. These cars may be getting a little too pricey for a poor guy to work on.

Does the valet key have a SKREEM chip ?

Re: New SKREEM pricing make me want to Scream!!
 

The only reason I checked key prices.. was because a member on facebook mentioned just under a grand at the dealership for a key .. she was given a link to the website.. and wasn't able to navigate it.. so I went to provide a direct link to the key... It's Mercedes doing this..

One can easily conclude the price hike is Daimler's way of compensating for the Trump tarrifs. I'm curious to see if the prices have remained the same at my local Canadian Mercedes dealer

Re: New SREEM pricing make me want to Scream!!
 

I'm just curious about if any of these cars are ever stolen. If so, there must be someone out there that knows how to get around all of these electronics. I wonder if the insurance industry has and stats? Lets hire a car thief to show us how LOL.

Re: New SREEM pricing make me want to Scream!!
 

Been studying a bit more and the SKREEM contains an RF transceiver and a microprocessor (with some memory I would think. Problem is we can't just remove it because it also controls the RKE and the power door locks.
And it is not a discrete signal, it is data blocks:
"Connected to the SKREEM is a Sentry Key Antenna Ring which surrounds the ignition lock cylinder. When the ignition is switched on, the Sentry Key Antenna Ring is supplied with power. A data block is transmitted inductively via the Sentry Key Antenna Ring to the SKREEM and then on to the Powertrain Control Module. If the antenna ring data block content is invalid or if vehicle battery power is too low to build up enough power for the antenna ring, the Powertrain Control Module will not receive the proper signal. This is displayed with the message “Start Error” in the Instrument Cluster"

OK then what we need to reverse engineer and reprogram the SKREEM to just send the data block which means we need to figure out the data block. No Big and may be easier than reprogramming the ECM.

Further: "The SKREEM retains in memory the ID numbers of any ignition key transponder that is programmed into it. For added system security each SKREEM is programmed with a unique secret key code. This code is stored in memory, sent over the CAN data bus to the PCM, and is encoded to the transponder of every ignition key that is programmed into the SKREEM." So what is needed is to reprogram the SKREEM not to interrogate the kay and just send the code.

Thoughts ?

Well.. Canada did see the light.. Germany might have to be next... PS.. Welcome to the USMCA

Re: New SKREEM pricing make me want to Scream!!
 

Where did you see that, Fox news?

Re: New SREEM pricing make me want to Scream!!
 

I like your thinking Padgett. I'm sorry I'm unable to contribute to this project workaround. Definitely interested in and applaud your efforts as I'm sure ALL Crossfire owners will have their hats in their hands thanking you for your efforts on this. Okay, hoping other folks here that have Padgett's thought processes on the SKREEM and ignition ring will chime in.

Thanks Padgett!

Lurking!

Yep.. CNN doesn't want to admit HE made it happen.. PS.. google is your friend..

Winning.. try it sometime.. name calling is the best you got I see.

Can we stay away from politics. This is a crossfire forum. Lets keep it to our special cars.

Re: New SREEM pricing make me want to Scream!!
 

Just a quick response: no, 1989 - that's when the major adversary went broke. Just a different kind of war. Also some little stuff later. (History, not politics).

Re: New SREEM pricing make me want to Scream!!
 

Back to subject matter.. caught a post where a Merc. owner picked up the ECU Skreem and keys from a salvage car and got his back on the road.. I'd guess way cheaper than "new" prices now for just the skreem.. we know the BCM will initialize and accept a new vin .. how about the PCM ?

Re: New SREEM pricing make me want to Scream!!
 

Suspect it took a DAS/STAR or something similar to initialize it. Could you send me the link please ?

Re: New SREEM pricing make me want to Scream!!
 

I was just browsing a google search.. didn't bother to book mark it.

Amen!! I get enough of that crap from virtually everywhere else.

dave is trolling he just needs a hug.

Re: New SREEM pricing make me want to Scream!!
 

Someone in an other post is in contact with Modulegods and they think they can reprogram and completely eliminate the SKREEM module but they need a working set of parts to decode them. They need a keyfob, Skreem and PTCM. He can decode what needs to be reprogrammed in the PTCM to bypass the startup procedure.
( disable the SKREEM entirely ) anyone have a spare car with working parts. After a SKREEM failure we would need to send in only the PTCM to be reprogrammed at a cost of about $200

Re: New SREEM pricing make me want to Scream!!
 

Thanks ! So far. no volunteers :(

Re: New SREEM pricing make me want to Scream!!
 

Re: New SREEM pricing make me want to Scream!!
 

not many have a parts car laying around unfortunately :(

I posted in another thread if members in their area could call around to you pull a parts and salvage yards to see if they have any Crossfires.

Re: New SREEM pricing make me want to Scream!!
 

Let's all pitch in a few dollars for a parts car haha. The skreem and damn traction control need to go.

Re: New SREEM pricing make me want to Scream!!
 

I wish I lived in Greenville, Jeff has three project/parts cars now.

We have a data logger in the lab that I could use to record what is going on between the SKREEM and PTCM/ECM. I cant program microcontrollers like some of my co-workers, but I have access to them as a resource.
It seems to me that one of these could replace the SKREEM (but not provide OEM capability, just provide enough to start and run the car without the original SKREEM and RFID in the key):
https://www.arduino.cc/

Adapting it to the CAN bus, i thought, would the the show stopper, but I was wrong - one of the guys in the lab says it has been done in other cars (but not to get around security, tho that is not the point).

This IS do-able, but I don't know enough about what is going on between the two modules. I think one of the GOOD tuners (Thinking of Josh or Rudy here) may be able to get around this.
But if we think the work around is a plugin module that will cost $79, we have another thing coming.

Perhaps for $500 it would be worth the effort... not sure.

Re: New SREEM pricing make me want to Scream!!
 

So is this a Chrysler screem or a MB part? I don't understand why the module wouldn't be the same or close as the parent corporations other models. Does the parent company change the screem module ( aside from the outside box) from model to model? That doesn't seem cost effective.

Re: New SREEM pricing make me want to Scream!!
 

It is a Mercedes part, 170 820 18 26. I have four of them, one in the car, one spare and two for some unknown cars.
So we can see what car first used it anyway,from the part number that would be the 170 series.
Not many sites list it but it is or was around $300, another site said it is not available now. I suspect it has been pulled back to Mercedes control.
