Everything worked great as soon as I installed the repaired dme back into my car. The only reason I knocked a star off is because there could be better communication during the process. I sent it in for diagnostics and they went ahead and did the repair without asking if I wanted them to proceed (which I wanted anyway so not a big deal). After they had the parts for 2 weeks I had to call to see what the status was on the part and then a week after that it was done. The extra key they cut for me works better than the original. I have been without a car for a year so it was very exciting to hear the car start first crank after getting my dme back.
