First, try to re-programme the RKE (Remote Keyless Entry) transmitters before searching for anything else. Assure that the batteries in the transmitters are in working condition and replace them if you are not sure. To pro-gramme the transmitters, perform the following:

Open the driver's door and let it be open throughout the programming process. Then, shift the mechanical door lock lever to the LOCK mode, turn the ignition key to the rUN mode. Within a period of twenty seconds, point a transmitter at the receiver dome and push the lock button for a period of five seconds at least. After the receiver has accepted the programming code the driver's door will unlock on its own. The first transmitter has been programmed, in the same extra transmitters up to four may be programmed in the same way, within twenty seconds.
If the alarm does not work properly, you may have a faulty alarm module and may have to be replace and its common problems with and older model. the systems work like a security systems, if you arms your system with the remote you have to disarm it also with the remote in order for the engine to start and run. The logic in the PCM prevents the VTSS engine no-run feature from arming until the engine start; Its one of the security systems jeep has and if you ask for my opinion its junk. hope that help some..

SOURCE: locks go crazy,alarm goes off, now the car won't start.

I've had this problem under warranty on my '05 Malibu LS. They replaced and reprogrammed the fobs. Looking in my shop manual, it seems the problem is from the content theft deterrent (CTD) system. My car started doing this two years later off warranty and now I just lock the doors from the outside with the key or by pushing the lock stem buttons by hand on each door. The security option in the DIC needs to be set to RKE for this to work though.

Try "cycling the key in the passenger door lock. Turn it all the way to the right and all the way to the left.
