I'm having a problem with my alarm sounds. It used to make a noise when I locked my car like a beep now only my lights flash and no sound how can I fix this?

 

First welcome to the forum.

I would suggest that you check the owners manual
for instructions re setting of features.
You may have inadvertently turned it off, although
a failed horn unit is possible.
If you don't have the manual they are downloadable @
Dodge.com .
