I'm afraid that most of the Porsche keyfob threads end up with the owner having to purchase and program a new key from the dealership. This comes at a total tune of $400 - $500.

Now, there is a slight chance that reflowing the solder joints will help, but be careful. Adding heat can destroy the small circuit boards. Many people use ovens and bake them for a short amount of time at temps at around 300˚F.

Hot air from a heat gun can work, but again, be careful to not over heat the circuit board.

Nothing is jumping out then as every thing that pictures will show looks good and it sounds like everything is physically functioning as it should.

These are pretty simple units, so once we rule out the battery (both the battery and the holder), the button, and the button on the cover, that only leaves the circuit board itself. Either one of the solder joints wasn't good and finally broke loose or a trace in the board itself has broken. Both are fixable by someone that knows what they are doing, but if you don't know such a person a new key is probably easier/safer.

Sounds like you have a good Indy, let them have a look as being able to see it in person may be more revealing.

If you have to buy a new key head be careful that the new one comes with it's secret number that is needed for the dealer to use to program to your car. Without that the new head is worthless. Not necessary to buy from the dealer as they will pick your pocket but just make sure you buy from someone reputable.

I got mine from Suncoast Porsche Parts and I see they have them on sale for @ $160.

Good news to report! Brought it to my key fob guy (yes I have one) and within 2 min he saw that the ground to the battery was bent and not making contact. Fixed and working, ….for now.

Thanks again for all the support.

Glad it was something simple.

Right? Is it a coinkidink that these cheap and easy fixes came right after I joined the Outpost? I think not. Who says the cheapest Porsche is the most expensive to fix? Bologna! ;)

Who says that? Might be a paraphrased version of Jake Raby's expression, "The cheapest Porsche you buy will be the most expensive to own".

I can attest to that first hand.

p.s. glad you found the "cheap" and easy fix to your problem.

I'd still like to see pics of the inside of the key body too.
