    Has anybody installed a reflashed GM siren from FerrariFobs in their car (https://www.ferrarifobs.com/sirens) and can comment on its functionality (specifically, confirm that the siren does sound during an alarm)? I know from past threads the GM siren has its oddities when swapped with the Ferrari-specific part, so looking to verify the reflashed part works as factory. Thanks!

    Can't comment on the siren, but have done business with FerrariFobs and have leveraged their support to make things work, and strongly recommend them -- honestly, if @gobble says it works, i trust it works.

    Justin- Mark knows what he is doing. If you do not trust him, you can always spend $584.65 at Ricambi for an OEM part.

    This is a brand new effort on Mark's part, so there are not too many of his sirens out there yet.

    I haven't tried the siren but I have used them for fobs. They are real so I would move ahead without any fear.

    This is the first I’ve heard of the siren. Great news!

    I Just recently repaired my Siren module.
    Opened it up and found the dreaded leaking batteries.
    The acid had leaked onto both sides of the PCB.

    Step one was to cut off the old batteries.

    I then used a wet paper towel to wipe off the acid.
    The acid had only damaged the solder mask but did not do damage to the copper underneath.
    After cleaning with water I then scrubbed with a toothbrush and alcohol to remove any residue.

    There are a couple of small traces in the area and I was worried about the acid possibly attacking the copper in the plated barrels which could be thinner than the copper clad on the PCB surface, so before proceeding I checked for continuity.
    It all checked out so I proceeded to solder wires on the board. I then coated over the exposed copper with clear nail polish to help prevent further oxidation.
    I decided to go with 6 AA external batteries as I was able to locate those nearby. Put them into a 6 cell battery holder and placed that into a plastic box.

    Nicely done! Curious how the 9V in AAs works out, you probably could just use 5 to get closer to the original 7.2V on the board. I used a Varta 6/8H 7.2V in a 9V case (https://www.amazon.com/gp/product/B07HY6ST9M) to get the exact voltage, but reading other threads, a regular 9V rechargeable appeared to work at least in the short term. Your board was actually in worse shape than mine, and I'm surprised to hear it's still functional. I'm going to take another look at mine and do a little better cleanup and continuity checking to see if there's any life left in it, otherwise I'll likely go with the FerrariFobs replacement siren.

    The individual rechargeable cells are 1.2V each. 6x1.2 =7.2V The actual voltage measured when fully charged was 7.6V. The battery packs sold are also made of individual 1.2v cells bundled together. All I did was bundle them myself.

    Exactly, and the 9V shaped rechargeable isn't really 9V either. That is why it works.

    Mark at FerrariFobs is fantastic. I’d add his products no hesitation.
