Posted this as a reply in the general forum, but I think it deserves to be its own thread. I've also updated and improved the original post.

INFO ON THE DIFFERENT KEY TYPES FOR E30s (and E28s I think)
Description of the 4 keys their cars came with here
This pic came from a 2011 ebay.uk Hartge H27 sale post. It's even laid out in the same order hahaha
Key 1 is the Illuminated Key - there should be an "S" on it but it's obscured in this pic
Key 2 is the General Key - also has an "S"
Key 3 is the Valet Key - note the "I" on it
Key 4 is the Wallet / General (coded) key, and is also a master - note the "S"
NOTE: more info on valet keys further down the thread here
Here is the "official info" from the E30 owner's manual. Some quick points:
- The "unlock inhibit" system is the deadbolt function mentioned above. You need a master key to use it ("S" Key)
- The "B" key is Key 3 above, the Valet Key with the "I" on it.
- Note the trunk behavior with the master key
Some GREAT key info here, posted in 1997.
As of this writing you can still get all the E30 key blanks and illuminated key inserts. you can also order coded keys from the dealer that get screwed into a separate illuminated key head. Here are some pics and part numbers. Hit up your favorite BMW supplier for best price. Stay away from ebay unless you want to pay 2-3x dealer price.

51211900892 Blank for the "General Key" - the one we're all used to, and is probably all worn out
51211900894 Blank for the "Illuminated Key"
32321109801 Standard Key (no plastic bits)
Haven't confirmed the valet key blank part number, but I think it's either this standard key or just a shorter version of it.

you use this with the coded wallet key the BMW dealer sells you (part number 51211900877, "General Key (coded)". It turns the combination into an illuminated key
51218105039 Replacement battery insert for the illuminated key (has a nice BMW logo now vs the original illuminated key head which has an embossed BMW logo)
32321151013 replacement battery for the illuminated key head
51218213607 BMW Key case (about $12 - someone posted one of these on the rare parts thread recently)
Will keep posting here as I find stuff - hope others do as well.

INFO ON THE DIFFERENT KEY TYPES FOR E30s (and E28s I think)
Description of the 4 keys their cars came with here
When delivered new in 1986, my car came with 4 keys.
1. lighted key which operates deadbolt function.
2. key with black plastic head (not lighted) which also operates deadbolt.
3. a valet key with a round head which operates door locks-not deadbolt-and will not open the glovebox door lock.
4. a wallet key with a tiny triangular head - functions like key 1 and 2

The master and valet keys are not different thicknesses, they have a different thickness of the center groove only. The valet key is made without the center groove "ground-down" so it won't physically fit in the glove box or trunk lock. The reason it won't operate the dead-bolt locks on the driver's door is that it is lacking length and "nodes" at the tip-end so it won't operate the "extra" part of the cylinder assembly.
The factory blank with the "S" engraved at the hilt is long enough to be cut to operate the dead-bolt function, the "I" blank is not.
All E30s with deadbolts came with "S" profile master keys (2), one headless master (wallet) and one "I" profile valet key missing the end "nodes".
If you cut an "S" blank from a non master-key, it will still not have the extra "nodes" to operate the dead-bolt.
If you cut an "I" profile master blank from an "S" profile master it still won't operate the dead-bolts.
I recommend using the factory steel blanks as the brass junk from key shops have been known to bend and break in the locks, particularly on keys whose code causes deep cuts and weak spots. Any key machine can cut the OE blanks, some shops just don't like to because it causes extra wear on their wheels.
