No, the SKREEM is still there. I have done the PB start on several of our Crossfires now. The first one I just took the transponder chip out of key fob, taped it to the ignition antenna ring and then ziptied those behind the dash. It worked fine except for the fact that I couldn't lock the doors with the remote for about 15 minutes after I shut the engine off. The reason is that with the chip taped to the antenna ring, it was communicating with the SKREEM and so the SKREEM thought the key was still in the ignition and wouldn't allow the doors to lock with the remote. I could lock the door with the key but I couldn't lock/unlock the hatch. After about 15 minutes the system would go to sleep and the chip and the SKREEM would stop communicating and then I could use the remote to lock/unlock the doors and hatch. So, after experimenting I now send the SKREEM and ECU to The Mercedes Swap Shop (you can find them on FB). They do a "key delete" which means they reprogram the SKREEM and ECU to disable the SKREEM immobilizer function which means the transponder chip is no longer needed to start the engine - just the cut key or in my case the PB start button. But the SKREEM also controls the remote lock/unlock functions and works with the central locking pump and the so now I can shut then engine off and lock the doors immediately with the fob. Works fantastic. The PB start kit is about $25 on Amazon and takes about an hour to install and the way I did it I did not cut or splice into any of the factory wires. If you go to the Crossfire Forum FB page or the Crossfire Tech and Rescue FB page and look in the files section I have uploaded the step by step instructions on how to do it.
@@bradmorgan911 Awesome, thx for the info. I am struggling with sending out the skreem as my xfire is my daily driver. I am not sure if I could be without it long enough to do the work of a delete. I'm just afraid that if my only key breaks, I'm screwed.
