The test (I've read) for the key taking to the car regardless the programming is the OUTPUT from the diversity antenna. It's a square wave I believe.

I just found my fluke scope meter and plan to figure this out myself since my remote stopped working on my car. I lost one of my keys or I'd have taken it apart to reflow the joints again but after I get a replacement I'd do that.

I have a clone car in my wife's so I'll do some readings from her's (working key) and mine with her's and my keys. I'll report what I find.
