I don’t have an answer for you, but I just wanted to say you probably won’t find an answer here for your issue.
It don’t appear to be a factory issue but rather an aftermarket issue, and without knowing more on the aftermarket alarm and radio, you will be hard pressed to find someone who can help. (I’m not saying someone won’t know)
My advise would to take it to an audio specialty shop to see if they can troubleshoot the wiring or something. If I remember correct the can bus system was really finicky in those early year Dodges. To the point when changing the headlights to your car caused issues the starter. Also since you installed the radio, make sure you use the correct PAC-Audio module and if you aren’t maybe you should look into using one.

First up... find it, learn it, love it. I'll be clear... I almost walked away from your request for help because you didn't do the bare minimum to make it readable. Not okay.

That aside...

The base cars at that age didn't have an actual alarm in the sense of making sounds and having sensors detect intrusions. The anti-theft system would basically disable the starter if the doors were opened while the car was in an "armed" state and that's about it. Third-party alarms could be added which added features, like hood and trunk pins that detect hose opening, or tilt-sensors to detect being towed, or shock sensors for being bumped. Plus, of course audible alarm to draw attention to a vehicle that was being abused. Some of those third-party alarms could link to the on-board theft-prevention engine cutoff. But a poor/cheap installer could just put in a third-party alarm that couldn't link in, which could lead to all kinds of strange behaviour.

From your description, I'm understanding one of your remotes is broken? Depending on if the third-party alarm integrates with the theft-prevention, that could be your problem in a nutshell.

Also, many modules in the car talk to one another on the CANBUS (network between electronic car parts). The stock radio may have been involved with the stock theft-prevention, and swapping it out may have interfered there. I don't personally know enough about the integration to offer details. I did have a 2008 with stock theft-prevention and an integrated third-party alarm, but I never replaced the radio head unit. With my install, I could use the third-party remote to do everything... or I could use the stock remote but it would only activate the stock theft-prevention. With your install, it's hard to say.

I'd recommend putting the original radio back in to confirm if its replacement is the actual cause of your problem, and make your decisions from there.

Best of luck.

Did not read. Sorry. Hope you didn't ask more questions in there.
