Thanks a lot for the help!

For a '90 just get a GM D-blank door key cut to code 91C9 and you'll have a functioning "valet". No jumping or dis-assembly.

Is this the car that was in Toronto?

I don't need the valet, I need the "power" key.

Valet - POWER = one in the same!

Oh wow thank you! I hope the local GM dealership got one in stock!

Do you think a blank key like that is hard to get?

You will NOT have any problem, if your question is the 91C9 code, that is just coincidental. I assure you if it's NOT been tampered with the D-blank 91C9 will work, even in a Canadian car.

Any GM dealer or local hardware that does keys.

Ok so I just have to go to any key cutter, tell them I need a key cut for a '90 ZR-1 with the code 91C9 and bingo?

If so, I think you're my hero.

I thought the original power key had a chip on it...

You don't need to or even want to mention ZR-1. It's not important. Just the D-code blank and the 91C9 code. The key will be an oval-head door blank. Don't be concerned.

No chips

Now if the owner has already by-passed the key and then lost/misplaced the key then I'd think he would know and pass on the information. In that case, if the owner has by-passed the key wouldn't be a factor, it should perform as an always-on modified car.

I likely have an NOS original key with the knock-out still in it.

Also...

On a '90 that has the (popular) secondaries deleted modification, whether there is a POWER key or not or whether it is turned on or not the FULL ENGINE POWER will be illuminated on the center display status screen (above the radio, etc.) IF the the switch has been modified (per Mike 100s post).

WARNING:

IF the chip has been modified so that the Secondary Port Throttles have been permanently "turned on", then the "NORMAL vs. FULL POWER (key switch) MUST always be in FULL POWER mode. Otherwise a serious/dagerous lean condition will exist and can result in burnt valves. So, to be safe, the wires going to the switch are often jumpered together (per Mike 100s post).
