So I wanted to see what kind of batteries the remotes took (found out they are CR2032) since one of mine seemed to be getting low. And got a little overzealous and cracked the case of my factory key. DOH! I bought some aftermarket flip key cases from China a few months back ($12.00 each off Ebay, multiple sellers) but never got around to doing the conversion since I figured I would need the assistance of a locksmith to cut the new key. Since I broke the key any way figured I would tear into it and see what could be done. Turned out very nice.

So first I confirmed with the key unlock buttons detached from the key you can still start the car. Which means there is a transponder chip somewhere in the head of the key assembly. I could really only see one area that was thick enough to house it. I scratched a bit at the surface of it thinking the chip would be housed in some silicone or something but all I felt was hard plastic. So started ripping and tearing at the plastic to see what I could remove. Not much is the answer. So I moved to a bench grinder to thin out the plastic walls a bit.

So once the chip was loose I then inserted it into the head of the new flip key case. It goes in the top section where the key pivots. You remove the small Phillips head screw at the back to separate the key pivot section of the case. Then you will see the spot for the chip. Pops right in.

Image

Then I turned my attention to the key shaft. Still had a lot of plastic attached to it after I broke it out of the case. Turned to the bench grinder again to remove the plastic attached to the metal shaft.

Image

Once it was all clear of black plastic I could see the shaft was very similar to the key blank that came with the new case. All except for a pin slot at the top of the key shaft that is used to hold the key in the base by inserting a metal pin to wedge it into the base.

Image

So lining up the shoulders of the new and old key shafts I could see the slot runs right through the middle of the hole that is present on the original key. SO I used a dremmel cut off wheel and made a slot right through the middle of the hole. Went a little too deep on mine so be careful those things cut fast.

Image

Getting the key shaft back into the base was a bit difficult. Seems the factory key is a bit thicker and wider at the top than the China clone. Not much, but enough to cause an issue. Little fineness on the grinder made it slide in. Re secured the pin into the base to lock the shaft in place and it formed a solid unit.

Image

Reassembled the case ( I may need to do a video on how to do that it's a bit involved ) and put a Holden sticker on the back and it is good to go. The case came with a Pontiac and Bow Tie Sticker but I got the Holden ones from the "Badge Man" Gary Whitby. I swapped over my internal circuit board and fresh battery into the new case but you can just transfer over your original buttons and battery if you prefer. They should fit just like factory.

Image

On Ebay a good search term for the item is "3+Panic Key Fob Case caprice"

From what I hear you can get replacement chips and program them to the car. Might be a better option than grinding the old one out? Anyone looked into those?

EDIT: Found out some more info on the Chips: The chips are Philips 2nd Generation Crypto chips. You can get them individually. I see one on ebay now for about $9.00. The Philips Crypto 2nd generation transponder chip is also known as the 46 chip or the Philips Crypto. All the ads I see says you have to take them to the dealer for programming but many of the G8 guys have been programming it themselves successfully using the instructions in the owners manual . Basically you have to have a good working key to do it. Turn the car on with your good key, turn it off and within 5 seconds put in the new programmed key and turn to the run position. Done. May want to buy one in case the grinding gets out of hand! LOL


Second Edit: Although I did not have the key blank cut in the new flip case I bought I noticed something I should bring up in case any of you are planning on getting the new key blank cut. It seems all the sellers on Ebay list our cars and the G8 as compatible with a HU43 key blade. When in reality our cars and the G8 come with a GM45 key blade. Slight difference so maybe they are compatible and will work either way but I am not sure so I just thought I would point it out. Seems the HU43 came factory in the GTO's so not sure if the sellers are just assuming compatibility in later years with all Pontiac's from AU.

Nice write up! Plan to do the same. I am fine with arrowhead key fob though (previous G8 owner).

I just did this mod on mine. My chip did not look anything like the pictures here. I had some sort of ceramic coating or something around my chip. It worried me so I only shaved enough of this coating to get the chip into the new fob. Maybe I just did not grind enough to get to the actual chip but the ceramic stuff was defiantly different then the plastic that I had been shaving off.

SMWALKER, do you have a website for the "Badge Man" I want a Chevy sticker for mine ( or maybe you still have the one you did not use? )
I am very happy with the new Flip Key. Now I just have to keep the Dealer from walking away with it if I have to service the Car.

I managed to get mine done with factory parts before the recall took all the Zeta flip keys away.

viewtopic.php?f=9&t=57&hilit=flip+key&start=0

Still had the original fixed keys and had the recall done with them, but I'm keeping the flippers--so far, so good.

Was yours the new after recall key? THe one I chopped up was the factory key, wonder if they updated the recall ones?

PM me you address, think I have 2 of the Chevy Logos, let me know if you want both of them. I think Gary only has the Holden Logos. He is only on Facebook as far as I know. a closed group. See if I can get an email for him.

Bringing this one from the dead. Just to add that I just did it to both of my keys but used the blank keys that came with them. They were exactly the same and had no issues getting them cut by the locksmith (other than cost of $60!). Now I don't have a key stabbing me in the thigh anymore!

Hey Moose provide a link to where you got your case and blank key blade. Did they specifically say it was a GM45 blank?

Didn't say anything about the blade type but just went on a hunch about getting it specifically for the Holden. Funny thing is that they included Pontiac emblems instead of Holden. Anyway, found some Chevy emblems on fleabay.

And there's also have Holden if anybody is interested.
