If my memory serves me if it is the SKREEM Module your Fob will no longer open the doors.
I see with your previous repairs you have viewed the mystery no start thread.
There are three relays the middle three in the ECM that engage when you turn the ignition to the on position. One opens again in a few seconds that's the fuel relay.
I would disconnect the battery pull out the RCM remove the cover reconnect the battery have someone else put the car in the on position and watch those three middle relays.
If that is well. Then check your fuel pressure. You can get in line gauge off of amazon. If the fuel pressure is good. Then I would recommend the crank sensor next.
These things is just what I would do. I am sure were going to get many opinions. There are some really great people here with years and years of experience on these cars.
Remember if you do buy new sensors only get Bosh or MB except no substitutes.
