Re: New SKREEM pricing make me want to Scream!!
What causes the key and SKREEM to be so expensive. G R E E D
Time to find a way of getting rid of the fob chip and the SKREEM.
Let’s face it the price to protect this diminishing asset of a car is rising faster than the value of the car is falling.
Is it possible someone has come down with a big hammer on NeedsWings?

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.

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..

I am sure that the US government would love to haul a foreign carmaker over the coals, why not try and get The Donald involved? Add a few extra percentage points to the Mercedes tariffs. Get him to mention this in one of his rants and they will be keen to give us all cheap SKREEMs and keys.
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 ?

Surely there is a government branch that protects customers from having to pay such an exorbitant price for two parts that could exceed the value of the car and force it to be scrapped, adding to the pile of scrap metal and unrecyclable materials.
