Control Module - Infra-red lock

Hi AL514
Based on all the info and research done on this car situation, I have come to the point to believe this car ECU was flashed to put it in an virgin state for reprogram and disable the immobilizer. Why I am leaning towards such point is because when I got the car I could have start it with the blade key and I had to lock up the car with the blade key as well without the remote IR FOB. This confirmed the immobilizer was disabled (I found a website that supposedly to have the step by step info on how to disable or bypass the immobilizer, but the info was taken down to prevent bad people getting their hands on it which makes sense.) There was no red and green LED lights under the rear view mirror functioning. And at that time, the lock control module was missing from the passenger side foot well. Only the alarm was working. After disconnect the battery for a few days to fix the driver's side window motor and when the battery was reconnected that's when this whole issue of crank and no start begins. I am now thinking the car previous ECU program may have got erased so the car ECU is now returned to it's virgin state and now needs to be reprogram. Some folks online are saying I will need a MB Star Programmer scan tool to reprogram it. Here are a few videos I was looking at where the first video guy was using an Autel IM608 to do so:

I have also noticed from one of the videos I have recognized the live data - Drive Authorization stored in the ECU with the Start Enable having a No for the value while being reprogram. See the image below

I tried to update you but the system wouldn't let me. Okay, I figured it out.

Yes, I tried going into the OBD2 option in the top left corner on the screen where all the cars manufacturers are listed. On my scanner it is called EODB. I had no luck with it connecting to the ECM. I am also checking around my location for a mobile tech who knows how to reprogram or flash the ECM for this car.

I am also thinking the previous tech when he flashes the ECM did not hard code some of the car manufacturer data such as the VIN number. Otherwise, my scanner would have able to retrieve it; instead, it is empty. I have to enter it so the scanner can download the proper data (Diagnostic Tool/FBS). My scanner cannot write that data to the ECM and allows the inputting of the VIN. I looked up the Autel scanner the guy from one of the videos was using is not cheap.

The only module the previous tech removed was the Anti-theft lock module. The DAS is still in place; unless the DAS module itself is bad, then that's not good. I will have to find a used DAS and ECM with the same part numbers and also get them re-flash and reprogram. I found this company which seems to be a national mobile tech services company who specializes in auto electronic for all makes and models vehicles name "Elitek Vehicle Services". Have you ever heard of them? I am going to call them this coming Monday to hear what they can do. I am hoping they can rectify the issue and at a reasonable price.
If you have any questions, I need to ask them let me know. Two heads better than one.

My car has a mechanical key with one button infra-red FOB only; I do not have the EIS (Electronic Ignition Switch). The anti-theft lock control module was removed, so only the mechanical key is used for open/locking and starting the car. However, the DAS must have been disabled to allow only the mechanical key to work without the transponder ring around the ignition to read the FOB frequency and send it to the DAS with the rolling code. DAS will then validate the data with the ECU which gives the authorization to start. Remember, I was operating the car with only the mechanical key until I disconnected the battery for about three days. When I reconnected the battery that's when the car stops starting.

You will have to focus only on the 1997 E320 W210 because it is easy to get sidetrack with all other info surrounding the E320. Every year Benz makes some changes to their electronic system. The 1998 model uses an EIS which includes the transponder and incorporates the DAS within the ECM, so the system is not the same as the 1996 - 1997 which has the components separated. I have accidentally left the key within the car in the "0" position for about two days and it did not work. Yes, the used transponder from the junk yard needs to get married/taught to the car so as the anti-theft lock control module. My infra-red signal receiver LED lights doesn't work and I think it's because of the anti-theft control module. My DAS is not an IR- DAS. The above image which year car is it for?

I am still looking for a local mobile auto electronic tech who has the proper tool to check the system and reprogram any of the modules that's need to be sync including the IR-FOB.
One company I located so for is "Elitek Vehicle Services", they claim they can do the job, but they don't go to homes. I will have to take my car to a auto service shop and they will go there and fix it. I hope to hear from a couple more mobile tech tomorrow Tuesday. I just want to weed out the possible causes.
