Before you replace the siren, as James suggests - just YANK IT OUT OF THERE and see if that fixes the problem. My bet is, it won't fix all of it.

1) High pressure car washes use WATER PRESSURE to clean the car, this can direct water into areas it does not belong. Less than a week ago, I got a call from a young girl who was in a panic, she went thru a car wash with her Kia and ti went into limp mode. The way to wash a car is simple: Two buckets, two mitts and some car shampoo. I know that no one wants to hear it, but that is the way it is.

"Anti theft went off" - what does that mean? Did you get the flashing lights? The Siren? Both? Any other indications? You must be specific, otherwise we are guessing.
Tried disconnection of battery and re-connecting, nothing fixed.
Took it to a Chrysler dealer after having it for 4 days said the Remote safety module was bad.
There is no such module. But then, it's a dealer and they can't fix the car, as there is NO factory support for the Crossfire. See my sigline.
we took the fuse out for the siren out but still the lights flash on and off. .
I suspect you got water into the Central Locking Pump/Security System Module (CLP/SSM) - probably thru the underside drains when the under carriage spray hit the bottom of the car.
Id yank the trim from the trunk area and look for water in and around the CLS/SSM. If you find water on/in/at the CLP/SSM, you found your problem. You must replace teh module and the last few feet of the wiring harness - used parts on eBay are one option or from a junk yard.
In fact, just yesterday I was working on a Roadster's inoperative top - I found a water damaged CLP/SSM, which explains the top not working. THe car in question sat in a garage two years. BUt just before they put it away, they drove thru 2 1/2 feet of water, flooding the CLP-SSM.
