I was not aware, but so everyone knows, you cannot reprogram a used key fob from a different Volt. Even the dealer is unable to reprogram. You have to get a fob direct from Chevy that is pre-programmed to your Volt if you want another one.

Maybe everyone already knows that. I didn't. Lesson learned.

Pretty sure there is a procedure in the Owner's Manual that allows you to do this. The caveat is that you must have one in your possession that is already programmed for your car in order to program the 2nd one.

Ok, just checked, page 2-5 of the 2013 manual shows you how to do this. Now if you lost both of your fobs, then what you say is probably true. But as long as you have one, you can program another one.

Edit: Oops, spoke too soon, page 2-6 actually does show you how to program new ones even if you don't have one already programmed. Only works for US cars for some reason, but claims Canadian cars can have programming done by dealer. Nowhere does it say that you need to get fobs directly from Chevy. Where did you hear this?

Yea I don't know where you're getting your information (oh wait, it's another idiot dealer) but you most certainly can reprogram remotes or add additional remotes. If you would have read the manual, or called your volt specialist they would have told you.
Even a smart locksmith is able to do it. Or maybe you live in Canada and your world is different.

Actually... I think you all have it backwards. The Kebob does not get programmed. It has a unique code number permanently assigned to it. The CAR gets reprogrammed to accept the key fob's code. In other words... The car can LEARN an new key fob. Or the car can LEARN an old key fob.

The key fob does not change.

And yes... The Stealership will do or say ANYTHING to get you to pay for another one. (Even if the car CAN learn any old Volt key fob.)

you can use a different key fob from another volt, the only rules are that
1- you cant cut a new key path on a used fob, like any key blank, it can only be cut one time.
2- you have to have all the key fobs together in the volt when you induct a new key fob. so the car can interrogate the key fobs all at one time and figure out what their individual codes are.

any key fobs that aren't there when you induct a new fob, get dropped from the list.

so you could make a fob that worked with the car EXCEPT for the mechanical door locks, from a used fob.

So this key fob with the wrong key can technically work. Until it's battery dies and you need a 'real' key.

I would not do this as a dealer since the key is not fully functional. A new uncut key needs to be obtained, the key cut, and the car programmed to the fob. This cost me $250 at a Dodge dealer (for a Dodge car of course).

It may be possible to disassemble the fob, insert an uncut physical key, and then use it. I'm not a locksmith, so, I can't answer this.

The dealer said they are not able to use keys from another Volt and I called my Volt advisor who confirmed this as well. How many codes can a Volt learn? I told my Volt Advisor what I was trying to do, and he first told me I could, then I asked him if he was sure, and he put me on hold and checked and came back and apologized and said they could not be used. He said that people will buy used fobs off of ebay and try to use it on their car and they cannot.

Is it possible the car can only "know" 1 code at a time? Perhaps that is the case. Anyone successfully get a used fob and train their Volt to use it and the originals?

Key with Integrated Transmitter Programming

Keys can be programming in various ways using the procedures outlined below. Using the Replacing Keys procedures will first erase all the known keys from the vehicle. Any existing keys and any new keys will then be programmed. This procedure should be used any time a key is required to be unlearned or erased from a vehicle. If a new key is being learned to a vehicle to replace a damaged, inoperative, or stolen key, the Replacing Keys procedure must be used. This ensures that the old key cannot be used to access or start the vehicle after programming.

The Adding Keys procedure does not erase any keys prior to programming. The procedure will simply program the key into the next available slot. The Adding Keys procedure should only be used when adding an additional key to the vehicle. The Adding Keys procedure should never be used to program a key to a vehicle that is having a key replaced, regardless of the cause for the replacement.



Adding Keys (With SPS)
Note:
• This procedure may be used with or without existing learned keys being present.
• This procedure will take more than 15 minutes to complete.
A total of 8 keys maybe be learned to a single vehicle.
• This procedure will only learn the vehicle key information. This procedure will not learn any immobilizer information between the body control module (BCM) and engine control module (ECM).
• If the battery voltage is low, charge the battery before continuing with the procedure.
1. Connect a scan tool to the vehicle and access SPS. Refer to Service Programming System (SPS) .
2. Ensure that all power consuming devices are turned OFF on the vehicle.
3. Select the SPS application and follow the onscreen instructions.
4. Select Reprogram ECU.
5. Select IMMO Immobilizer Learn - Setup.
6. Select the Program Transponder or Remote Key (Add) function.

The physical key part can be replaced on the remote. It is just held in with a small pin. So you could get just the key portion cut, and replace it on the fob.

So basically your dealer and the volt advisor is calling the manual (and us) a liar? Oh, the drama!!
I trust what is in print more than the "knowledge" that spews from random peoples' mouths. It CAN be done , and HAS been done. No if's and's or but's about it!!

thanks for the correction Somms, I wonder if there was a change after 2013. I don't recall the "add a key" capability when I added a new fob to my 2013. the OM is a bit disjointed on this point, stating both that to replace a lost key all the active fobs must be present and that to add a new key, only the new key and one other of the active fobs must be present.

as for the idea of programming a new transmitter with an incorrectly cut blade, I can't answer now. (though I did earlier today) the key blade is put into the dash top key slot as part of the reprogramming process, I always thought that this was a blank key slot, with no keying (pins if you will) , but I have not verified this. if there is a keyway in that slot, and it has pins, then the key has to be cut correctly, but I have no specific information to confirm this.

yes, I know that these are not pins, they are cut windows, but its the same principle.

I just bought an extra FOB from my dealer. It was $40. I needed an extra set as my wife has a habit of once in a while taking my keys along with hers. I need a backup in case this happens again!
