That IS a dodge part number
internet shows no longer available from chrysler, but there may be an updated model available- you need a dodge specialist
and a high failure item, which is used for many functions beyond anti-theft

good tip to pull fuse #13 and then test again
( note that 315 MhZ radio frequency can cause this to fail...like added CB radio*)
If the Dodge dealer can't sort it out she is either screwed completely or at the wrong dodge dealer
dealers tend to hire new techs right out of school, short on experience and with book learning of model from recent years only
I'd start calling around
I do not know IF that diagnosis is truly the problem and if the module is a straight swap or it it needs to be programmed
