how do I reprogram my keys. The Jeep is not recognizing either key. on 2004 Jeep Grand Cherokee

The car stalled out on us after being parked for a while. It would start and idle but when tran engaged would stall. Due to previous experience I changed out fuel pressure regulator/filter. Same deal. Now, I see an invalid key icon, and gauges won't come up. It turns over but no start. I understand it has to do with SKIS but can't find any trouble shoot info or similar reports. I'm stumped.

Could be a shorted bus line to any of the control modules... instrument panel, PCM, BCM, Auto A/C control, radio and so on. If it has been sitting for a while I would look for rodent damage to the wiring, mainly under the hood. I don't know if your area has a rodent problem like ours does. If you don't see any damage the system will need to be diagnosed.
