How to get the key code without going to the dealer? They want $125 for the code and $150 for code with the key.

It would be very helpful to us if you updated your profile/sig with your vehicle information.

^^^ What Mike said, having that info in your sig really helps.
Is this about your '05 Impala SS?

Yes,

Do you have a currently working key, from what you said I am assuming no, but asking to be sure.

Either way give this a read.

You could try to get blank keys from somewhere on the net, I do not know of any good places to get them from though, and the only one I could find that says it was for your year car was the following site.
2000-2005 Chevrolet Impala Blank Ignition Key

If you have no original key already cut, and you purchased the new key, you would of course have to get a locksmith to cut the key to the cars ignition, then you should be able to program it via the 30 minute method, I have never personally done so though, so I am just going from what I spent the last hour reading.

30 Minute Relearn Procedure (Steps): This is for a "replacement" (new) key (no original available)
1) Insert a "Master" Passkey III (PK3) Key (the one with the black plastic cover as shown above).
2) Turn the Ignition to ON, but do NOT start the engine. You should see the "Security" message on the dash for about 10 minutes and then it will turn off.
3) Turn OFF the Ignition and wait 5 seconds.
4) Repeat the above steps (1-3) a total of 3 times, or a total of 30 minutes.
5) After the third time (including turning back to the OFF position), start the van. The van should now have "learned" the transponder information and will allow it to start and continue to run.
Important Notes:
- When the above procedure is used, all previously learned keys will be erased from system memory.
- Additional keys can be learned immediately after the relearn procedure. This is done by inserting the additional key and turning the ignition to the RUN position within 10 seconds of removing the previously learned key


Found that info on a chevy venture site..

x2 as above. Good info!
My Pk ave 97, had only one original key and I wanted one more ready in wallet, so that if I ever locked my key inside trunk or loose it... I can still get home!
My older GM Passkey II system also has to be programmed and I phoned around and managed to find a local locksmith that easily produced a key and encoded for $55.
I then made sure it actually worked in car door lock to open and that it starts the car fine.

Thx, I have a key that works intermittently. When I place it in the ignition, it won't turn. Sometimes I have to remove it and replace it several times to get it to turn. Other times jiggling it will work. The longest it took to get it to turn was 10 minutes, I was told eventually it won't turn at all no matter what I do.

are you sure your key has a chip in it? have the dealer run the VIN to make sure. my 00 impy has the sensor, but no chip key. the SS had it as an option, but if i remember correctly it wasn't standard.

if it does have the chip in the key, any reputable locksmith can duplicate the chip. the key not turning wont affect the chip at all.

I agree with Jason, the chip should not stop you from being able to move the switch to try to start the car, sounds like your ignition switch itself if starting to go bad.

I didn't mention the key had a chip and it doesn't have one. I just need the key code.

The locksmith said the cylinder is good, it'* the key that'* worn It'* worn so bad, it'* causing the problem. I don't have a problem starting the car, it'* getting the key to turn. He cut a new key from it and it'* having the same problem. That'* why I need the code, so he can cut a key using it. Also The key I have is a copy, I don't know if it'* of the original or a copy.
