I have never seen the schematics to our key fob. There maybe someone on here that has them. I can not tell you the difference between the two circuits if I don't have the schematics.
In my opinion and what I would do is just buy another key. SOS, Needswings, and Chrysler have new keys. Not cheep! The piece of mind that a good working key would bring me is worth it again in my opinion.
