I had he same problem with the siren of my 355. I made the mistake of taking the car to the dealer and I told them to replace it, thinking that if you can buy a brand new alarm for about $99.00 at Mother's, just a Siren/battery should not represent a big expense. I was presented with a $400.00 bill (and they were nice enough not to charge labor).
For less than $300.00 you coud go to an alarm and window tint place and get a full system that is probably of a better quality than the factory one. They can even program your own original remotes with the new codes.
