Does the door and trunk use a different key than the round ignition key? I only got the one key and what looks like a universal remote with my new to me 2001.

 

The Driver's door, Cubby, Boot lid and Ignition all have the same 'cut' but the VALET KEY has a different key tip that will not operate the boot lid or cubby locks.
All TIBBE 8 cut KEYS will LOCK the 'tumbler' set in the door but only the correct key will UNLOCK it.(don't know about 6 cut)
The boot lid lock is seldom used by most people and when you try to use the key after a few years of NON-USE it will not work. The lock gets 'jammed-up' with corrosion and debris so you need to lubricate and work the lock to free it.
I had to spend up to 10 minutes lubing and working the key in a customer boot lid lock before I got it freed.
USE the key in the door and boot lid a few times a year or cry when it gets stuck!!!!!!!!!!!

 

And this key is different than the round ignition key, which is the only one I have?

 

It's possible the ignition barrel has been changed.

 

my 2002 uses one (black) key for everything.

^^^^ this !!!^^^^

everything on these cars needs to be used frequently or issues associated with disuse will arise.

that includes all the electronics, sounds system, and nav system if so equipped.

i didn’t use my CD changer for months (years ?) and now I’m paying the price.

I better start using that cassette deck. ;^)

 

I am going to get a cassette adapter for my iPhone Airplay.

 

The cars came with Tibbe keys (the "round" key you're looking at). Look at the very tip of the key -- if it goes smoothly from the tip to the first cut on the side, that's a Valet key. If there is a tiny ":ledge" profile cut between the tip and the first big cut, that's a standard key.

Valet keys open doors and work the ignition lock, but they are NOT supposed to operate glovebox or trunk.

A few moments with an appropriate tool can put the profile onto a Valet key, converting it to the standard key.
