Im dying to get this fixed - Flipkey for my 2004 RX8
 

Hello guys, I have a RX8 in Sweden, and I saw that some of you made a own flipkey to your rx8's. And im very intressted in this.

I called the Mazda RX8 service in Sweden, and told them that i wanted a flipkey for my rx8 2004, and they just laughed:( They said its impossible, there is no way that you can build a working flipkey programmed to your 2004.

Now i want to show that bastard, and shut him up. But what do i need? I heard that the hardest part was the keycut, what exactly is a keycut? And its pretty easy to get it programmed right?

Will this work? -- >http://cgi.ebay.com/ebaymotors/NEW-0...mZ300261060193

Thanks for all help!

I dont mean the programming, i want to know what key i should cut and put into my new fob? They key im currently using or the service key?

You don't cut the key and stick it on to the new one.

The OEM flip key thats on your ebay link has an "uncut" key inside, and it should be the exact same size as the keys you currently have ( the blade part). Just bring both the uncut and cut key to a locksmith to make a copy.
A guy on one of the thread got his copied at Home Depot, I used to get my car keys copied at Lowes.

Also your going to need two of your original keys to program your new flip key, if i read those thread correctly.

Let me see if i got this right, when my flipkey arrives from Ebay, I take that one and my current rx8key to a locksmith to copy it.

I have to make a copy of this key right http://www.msprotege.com/members/Cap...5/key%20gb.JPG ? And then they put the copied key into my flipkey?

Yes i have tvo orginal keys, so i dont need mazdas help with programming right?

Thank you

Yes the flip key should have an uncut key blade inside, and it should be the same size as the picture. your gonna need two original "coded" keys (not the service) to make the car learn the new flipkey and then, go on with the programming for the remote.

Your rx8 came with remote lock/unlock right? since I'm not really sure of the EU options, I only got 2 flipkeys from the dealer (USA), but it seems like you guys get 3 keys? Master, spare, and service? and I guess a remote fob?

I'd re read the other threads just to be certain. Can anybody else confirm what I said?

Yeah, i have two original coded keys. Thats right, i got one master, one spare, and a service key, and i also have two remote fobs with lock/unlock, trunk opener and panic button.

So I have to make a copy of my master key, and then put it into my uncuted flipkey?

Here's my contribution to this search challenged thread :)

My RX8 is from Germany and its a late 2003 modell. I think I know what the problem is, US remotes doesnt work with EU cars simple as that. My current remote has 4 buttons, lock, unlock, trunk release and larm off botton, but the US model has the panic button instead of our "larm off" botton. What year are your rx8 from?

wonderful, yes it is so, You can not use US keys for European version RX-8.
And by the way the US model key with panic button won't fit to your key wich is with alarm off key. I bought mine key on ebay from England, but it was used and it was with alarm key off.

I found one on Ebay here you can buy it, but I am surprised that it is so cheap, i bought mine for 40 euro and it was used:
http://cgi.ebay.co.uk/GENUINE-MAZDA-...d=p3286.c0.m14

it can be done!

So does the UK remote works with all european RX8, I dont want to buy another remote which wont work again. Can you please give me ur visteon number for the UK remote?
And I also what to know what modell your rx8 is from and what country it has been sold to. Many thanks.

I am now at work, but when I will be at home I will watch what for number I have.
By the way I have 2004 year and bought it from Germany. :) the key visteon nr. wich I bought from UK, was equal what I had.

Must the visteon number match exactly for working with the car?

My visteon nr. is 41844.
Somewhere I read that there can not be various numbers and I know for sure that if you got exactly the same nr. then it will work 100%.

But the problem is that there are no flip keys with visteon no.41844

right, there aren't, but why do you need a flip key, do you have the original key too as a flip key?

So you have checked that out? There are absolutly no flip keys with that Visteon number?
I do have the orginal remotes and keys, but I really liked the flip key.

I managed to code the key itself, but I couldnt program the remote. Thats all.

my original visteon # is 41848. If yours is not the same and you're certain that you're performing the binding process properly then the only thing we can conclude is that they are incompatible...

My best guess is that Mazda swapped out the components at some point during the 2004 rollout. This is also probably why no one will openly market a 2004 flipkey...

What is your cars manufacture date? Mine is Nov 2003 if memory serves correctly.

wonderfull - yes there aren't any...
So we must stay with the old fashioned key... :)

So your orignial visteon # is 41848 and also ur flip key has the exact same visteon number?

My original key's visteon # is 41848.

My flipkey does not have a visteon nor was 41848 listed as a compatible number for it.

Can't program my new flipkey...
 

I just recently picked up a used RX8 with a late 03 build date. I got a brand new blank (flipkey style) from the dealer, and have two programmed keys (black head). For the life of me, I cannot get my new key to program. I've tried all the techniques that seem to work for most people but so far no luck. I even removed the key chains, and keyfob on the new flip key thinking that might be causing interference. Everytime I get to the new key the icon just flashes fast.

Oddly enough, I have been able to get the remote working like a champ. That was cake compared to progamming the key.

Is it possible that keys can go bad or be different? From what I've been reading, all the keys should be the same as far as coding right? The only other thing I could think of is that the PCM is maxed out on keys assigned. Is it possible to tell if your car/PCM is maxed out with 8 keys assigned? Is there required wait time before trying to program the key again?

I've been reading up on all the related threads by searching, but none of the threads I found go into detail around this area.

Thanks in advance!

Sounds like you know as much about the process as I do. The only difference is the results. I spent 10 minutes binding the key and remote on my flipkey.

Looks like I got lucky. A number of people with build dates around the same time as mine have been met with failure, although it seems to be more often the remote they have problems with, not the actual key.

Aww shucks... I was hoping this would be easy as most people described. Seems the easiest things always ends up being twice as hard. Gosh darn it to heck.

Talking with a nearby service department at a local dealer, they were saying that programming Mazda keys are tough. That they charge so much for labor as a flat rate because programming can take anywhere from 5- 45 min or so using the WDS system. (So they say...)

I ordered another blank from Ebay , hoping this will shed some positive results. Wish me luck!

Thanks for replying ShellDude.

FWIW, their own service manual basically states to keep trying until you get it to "take".

one of those potential infinite loops if you look at the process flow.

Yeah I noticed that as well on the dealer documentation. So I'm clinging onto the hope that it might work eventually if I keep trying. I tried several times last night before calling it quits, and then again this morning. Still no luck, but... Hope I get lucky.

New Key Worked!
 

I bought a key blank and transmitter online via ebay (seller: midwestkeyless), and got it cut this afternoon. Had both good keys with me, so I tried to code the key and it worked like a champ. It looks like either the keys can either go bad, or there's certain ones that will work with late 03 and early 04 build RX8s. The first blank I had cut was actually from the dealer, and that will not work at all. I didn't get to see the P/N of the key, but the service tech left me with the impression that they were all the same.

In anycase I just wanted to pass along my experience in case someone else runs into the same situation as I had. I'm switchblade Pimp Status now. :D:

Same guys I went through. Glad you got it straightened out.

Congrats! I wish I hade problem with the key coding, my remote still wont program and I dont know what rremote would work with my car.

Thanks! I seemed to be the odd one out with mine. I had problems with the key instead of the remote.

What FCC ID and IC does it list on your new flip key? The flip key that seems to work for early build US spec cars are:

FCC ID: KPU41788
IC: 4238A-41525
Visteon No. 41524

For reference, my original FOB had this info:

FCC ID: KPU41805
IC: 4238A-12076
Visteon No. 41848

If it's true that US spec cars PCM won't work with EU, maybe they're the same as the ones for Japan and can use one that was made there?

Yeah, something like that.
The Flip key I ordered were
kpu41788
4238a-41525 visteon. 41525

Didn't work at all, And I dont think the other remotes u mentioned would work either.
Did you have the same visteon number on your old fob as the flip key?

My old fob has the visteon 41844. No FCC ID, No IC.

Dude, I finally got myself a working flipkey. I bought one from UK and it worked perfectly with the programming this time. The US remotes has another freq. thats why it didnt work in the first place. But I notice that the battery inside the fob is weak, how do I change the battery? I searched, but I only found when they explain how to separate the key from the fob.
