Thanks Gent for your answers. will try to be as precise as possible

Well I've got enough things to start trying to locate the alarm module and find out. I only have one key FOB, the other wasn't with the car.
I didn't find any mention about the "batteries age" in owner_manual_crossfire.pdf, is the regular manual found on mopar the one you're reffering to?

fuse #9 seems to be good to me, since the roof light and the trunk light do work.

Is it possible the fob is from another car and only allows the car to start? You never know what someone sells you until you find it does not work.
The fact that the light appears in the red window on the fob just proves the fob batteries are good.
There are batteries available for the car and they will flash the lights and beep in sync with the indicator lights.
It is a good sign that the locks work using the console button, so the problem lies in the signals sent by the Fob or the signal receiver.
This receiver is behind the map light area I think, see if it looks like someone has played around in that area.
I am no expert by any means on this subject though. Pizzaguy may know the answer hopefully
Good luck..
Here's what i could say : the key turns on the car and the transponder is OK. it was glued inside the key on the upper part, which makes me think it's the original key / fob since you can't displace the transponder without breaking the glued side (which is what I did but hopefully the thing still works)

When you talk about the map light, is that the same thing called the roof light? because there really is something related to wireless with 3 buttons and a red light but i believe it's the garage door opener. Am i wrong?

any sentence with SKREEM gives me a headache. I've seen enough posts to see where it's going...
