My story:
'05 SRT6 with 34k south FL miles. Original battery died while car was locked (alarm activated).
When the battery dies and you are forced to manually open the car, the alarm will sound. Short of it is I bought another battery from dealer in Plantation, FL and installed. I had to pull the fuse for the alarm as the alarm will WAIL nonstop.

All in all a pain in the ****. You are better advised to replace ahead of time. The parts lady told me the Chrysler batteries are Interstate, FYI.
