I can only tell you to read thru the process. I know you can buy new ones, and I know there is some programing of the key. There is a how-to on it somewhere as well. Module is located behind the instrument cluster. I have never been in there for any reason thus far, so I am of no help. I hope I never have to. Some of the "locking" mechanism is in the trunk area. Moisture getting in there has caused problems as well, with locking and unlocking. But, the starting issue is sometimes related to the skreem module. In your case, the skreem seems to be the problem. Like I stated earlier, with the CPS, crank no start, with the CRM, no crank. In your case, cranks a couple of times, then nothing. Unplug the battery, replug, repeats...that is classic skreem symptoms.
