Can a key open the doors even if it doesn't have a transponder chip on
it? I want an inexpensive backup key for my wallet and was wondering
if I can get a key that will open the door but not start the engine.

Yes -- The door lock is mechanical -- no computer widgetry required to turn
the lock cylinder.

Won't set off an alarm or anything then?

Would have to be one weird alarm system. I've got a transponder key
(different make of vehicle) and got a "regular" key for a backup like what
you want. Right off I opened the door with it and then tried to start the
vehicle. Curiously, the engine started, but shut itself down after a couple
of seconds and wouldn't re-start until I used the transponder key.
Seeing as how I have *never* hear even a whisper about any manufacturer
tying in the transponder key to the door locks, please post if you find
anything different...

The reason it ran for a few seconds for you and then quit is that the
PassKey system generally disables the fuel pump when the alarm goes
off. So you just used up what fuel was in the lines and then there
weren't no more until you used the transponder key and thus
reactivated the fuel pump.

Cool. But that just adds weight to my believing that a non-transponder key
(cut the same) would operate the (mechanical) door lock. The only thing even
remotely "electronic" on a door lock is the electric lock opener/closer, and
that's just a dumb solenoid operating a mechanical link.

It's not quite that "dumb"... my Silverado has a switch on the lock
mechanism so that the system knows whether the key was used to open the
door; or if somebody reached in through the (perhaps broken) window and
unlocked it from the inside.
