My 2007 C4S only came with 1 key. I bought a blade that was cut to copy my existing one. It works to open the door and fits in the ignition.
From reading several posts, I surmise that I need another key head with the chip in it to operate the remote functions and disable the immobilizer, enabling the car to start. Then I need to find a decent dealer to program it for me.

Assuming all that is right, here are some questions that I have:
1. Can I take this opportunity to program a 3-button remote to a vehicle that originally came with a 2-button remote?
2. Will doing so enable me to long-press a button to roll the windows down?
3. Any good sources for key heads?
Suncoast wants over $218, but doesn't say whether they will give a 3 button key. Just that it might be black (my original key is the older grey style).
Ebay has used heads with new chips for $110, but I'm not sure it will work.

Any information and/or advice would be appreciated greatly.

Its my understanding the dealer will only program a brand new porsche key. Some will only program one if purchased from them, so call around. So option 2/3/4/ don't actually work for you. Unless you wanna buy the 2 button and then swap the guts after its programmed.

Cab or coupe? What's the third button for on a coupe? Euro cars (cabriolet), third button is for cab top operation. US cars are not programmable to use this third button feature, so a SmartTop module is needed (using a two-button key).
Long press to roll windows down - I did enable this on my cab using a Foxwell tool, but it's a pain (and honestly, I cannot recall if it enabled only down or up, but it was not both, I think up only).
I don't think a 3-button remote can be linked to a 2-button car - especially as there are different key frequencies in use between EU and USA (FYI: I have not idea if US-bound Porsches had to comply with any FCC requirement).

The best solution for your quest is to find $400 for a SmartTop module and install it. Works for coupes too, I believe.
I don't think you will have joy down the dealer route. They really don't give a f*. I'm sure there's a better independent in WA.

EDIT: disclaimer - I own a US cab, so no idea on US coupe button options.

THanks for the info. I have a US spec Cab also. I also have the foxwell, but didn't have any luck when I tried to enable remote control for the windows. What's the button sequence for it? Just press and hold the lock button, right?

I'll look into the $400 module.

Thanks again.

SmartTOP is the only way to get what you want, feature-wise. I went down the same route a few years ago. Once I got over the price, I never have looked back after the SmartTOP install, such a great integration.
I have no affiliation with this company, just really like the product as do many others: https://www.motivemods.com/Mods4Cars...4c-stlbpe1.htm

As for the window auto up/down code sequence, it has to do with the "comfort" functions related to windows. If you search Rennlist, you can find some threads from those who took the time to detail the process.

I never knew a 3-button one existed but if there were one that had discrete lock and unlock functions I'd spend $200+ just to have that. I hate the ambiguity of the lock/unlock toggle.

Unfortunately not how the 3 button works. Most of them are for Cayman/Boxsters - the 3rd button opens the rear hatch/trunk.

Buy the genuine 2 button. But search around. Then have your dealer program it. Your Indy may be able to as well.

To control the windows from the remote don’t buy the smart top, buy the one made for your car from them. It’s called remote key. It’s. $210. Link. It allows your to one button roll up and down your windows. Also make your car chirp with locking or unlocking or both (best feature, I can sometimes not hear it lock). Also adds one touch up/down for passenger.

Easy to install.

didn’t realize OP has a convertible. Above for the coupe.

My 2007 C4S Cab came with two keys, one three button and one two button. Both housings were broken in one way or another. I replaced both housings with three button versions. The first button is lock/unlock, the second button opens the frunk, third button doesn't do anything. I'm thinking the third button doesn't have any function on the US Cabs.

I looked into that one because the horn confirmation would be very appreciated. It doesn't appear to operate the 911 convertible tops. Only those of the boxters. So I suppose the question becomes, "is it worth the extra $170 to be able to open and close the convertible top from the remote?" I'm leaning toward "yes".

Sadeeq

Me too. Unfortunately, it sounds like the 3-buttons are only for European versions of the 911.

Ordered my used 2-button fob with chip off eBay. Hope it can be programmed to work!

Yes, if you have a cab, smarttop is awesome and an easy install. Allows me to drop the top or put it up from the fob. works perfectly every single time...so far...

If it was switchblade styled I might consider it, but I don't see the advantage of those. Am I missing something??
