It has to be within about an inch of the key slot.
When I programmed my spare "guts", I had one cut remote key. I programmed the one, then simply swapped guts (I didn't have the cover on, so this is easy), inserted the same key a second time with the different guts, and programmed the second set of guts. Popped the cover on, and I have two sets of guts, but only one cut remote key. I'll get around to ordering (for the THIRD time...) a cut blank some day, and just pop the spare guts into it, and I'll have 4 keys (two remote keys, one of each Transponder key plus two bananas) all programmed to the car.
As for the "security" issue, I don't see a whole lot of difference between secreting a whole key with transponder someplace and separating all the guts & storing just those someplace. If someone really wants your car, and **knows** you have a transponder in the car, they'll have no problem using s slide hammer on the ignition lock, turning it with a screwdriver, and driving off, using the transponder you put in the car.
If you want this for an emergency measure, then it's as simple to tape a whole transponder key someplace out of the way, like in the trunk under the spare, or behind a trim panel, so you can drive away once you've gotten in the car with your transponderless key. All you need to do is not make it common knowledge that you are doing it (and make sure the tape won't let go & drop your key into an abyss...).
I suppose, if you got a Transponder Key, you could remove the chip, and epoxy it someplace out of the way, but in proximity to the key slot so that it works, and use a "flat" key (often done to make "remote start" work on these cars). But again, someone who knows the car may realize you've got a "different" key setup.
If Ilco makes a programmable transponder key that's to your liking, then perhaps that's what you want.
Big keys are a way of life these days with most cars, especially European cars. Electronic security, like the transponder, is here to stay. Buyers want all the functions in one device, so the separate remote fobs & keys are all but extinct.
Personally, I feel it's more trouble to administer and track the separate bits all around than just to keep the keys as supplied. I occasionally valet park my car, and it would be a real hassle to have to remember to bring a different key for the valet to avoid tipping my hand, or worse, if your car were truly desired, and you bypassed the transponder-in-key setup (by gluing a chip near the ignition lock), then a knowledgeable criminal working as a valet could take an impression of the key & cut a blank (see: "The Great Train Robbery" with Sean Connery) & drive off with your car.
Of course, the need for absolute security with these cars is debatable, and what I wrote above is extremely unlikely. Saabs aren't high on the list of most stolen cars, and OG 9-3s are approaching 10 years old for the youngest, so...
