Hi there everyone.. I am new to this as I inherited a 2002 Mustang GT dropped off last week from my brother who gifted it thru his passing. So, there is a sentimental value here as he loved his mustang! The problem is upon the transport company dropping it off, I can't get into the vehicle due to the alarm setting off. So, I figured I would jump out and then relock the car manually as his remote keys don't work. My question is....is the battery really dead or does this have to do with the alarm system preventing the car to start up? Thanks for any and all info. Look forward to comments.
