Hi guys, I'm a UK 8 owner and have bought a switchblade remote key from eBayUK. Unfortunately, I bought it before i knew this place existed.
When i pulled the key apart, it turned out to be the Mitsubishi version (still branded with the Mazda logo). Followed the instructions for coding the key and that worked a treat. Starts the car no problem.
However i can't get the remote to open/lock the doors. Have tried the programming method on here. Would the Dealers be able to programme the remote to work? Was thinking of telling them that it used to work but has stopped since i changed the battery, but that it still starts the car.
Don't want to turn up at the Dealers and look like an idiot when they tell me that the Remote will have never worked.
Any help greatly appreciated.
Many thanks

please read my post nr 250 in the previous page.I mention there that the Mitsubishi remotes won't work-we tried it. You MUST find from Ebay a Visteon one (No 41787). Ask your Ebay seller if he can exchange it, or buy another one after you make sure its a Visteon

Thanks for the reply, i read your post earlier. Just out of interest do you know what models the Mitsubishi version works on? ie Mazda 3/MX5 etc. Have been speaking to a Auto locksmith today who says it should be possible to program the key, though when i take it through to him i'm gonna check that he isn't just going to use the method that i have allready tried. Not sure if its going to be worth the £40 to find out what with your info.
Will let you know if i go ahead and take the chance depending on what metod he is going to use.
Got my hopes up when i managed to code the transponder so that the key will start the car.
The keys are as rare as hens teeth on eBay but will keep looking.
Cheers

Does anyone know if the procedure defined in this thread will work on 2006 and newer? I bought a new smart card but I cannot get the car to automatically lock/unlock itself after 3 on/off's of the key and 3 switch presses. I've tried it really fast and pretty much every speed within 24 seconds you can do. I have a 2006.
thanks.
thanks.

I thought you guys would like to know some more stuff. All the RX8 models use a static code transponder. You can program, or use Jet Smart Clone which is expensive but does all static code cars with a single key and the cut spare; which is a lot of makes.
There is also a way to get pass the transponder with handbrake and some sequencing, but I don't know it. Most chip key cars have them, Honda is the only one with it public.
I'm trading mine in on a 09 soon and will see what has to be done with it.

Are you able to get the car in programming mode for the remote?
There are some remotes that unfortunately do not work with the 8 but we should make sure the directions were followed before blaming the remote.
Remote Programming
· Ensure that all doors, trunk, and hood are closed,
· open the driver’s door
Carry out the operation below within 24 seconds:
· Insert key
· Turn ignition to the run position and off, 3 times
· Leave key in ignition
· Push door switch, 3 times (The door switch is the little rubber one on the jamb of the rear door next to your elbow when sitting in the driver’s seat, which controls the interior lights.)
· Car will lock, then unlock (If it does not: wait 40 seconds and try again)
· Push 'Lock' on first remote, 2 times,
· Push 'Lock' on second remote, 2 times,
· Push 'Lock' on third remote (new), 2 times,
· Now all 3 remotes are accepted by the car.
A person only needs one working remote to setup a second remote but you need to program all remotes you have (up to four) when adding a new remote. Otherwise the remotes not programmed can drop off of the car’s database.
Key Programming
1. Have the additional key (key 3) ready (cut) for registration.
2. Using key 1, turn the ignition switch to the ON position (do not start).
3. Verify that the security light in the dash (looks like a little lock) illuminates for approximately 3 seconds and goes out.
4. Using key 1, turn the ignition switch to the LOCK position within 4 seconds after the security light goes out.
5. Remove key 1
6. Repeat steps 2-5 using key 2.
7. Repeat steps 2-5 using key 3.
8. If additional keys need to be registered, repeat Steps 1-7 in the same manner as key 3.

Im guessing that my remote is bad. I tried these steps and it did everyhitn he said it would (locked+unlocked doors) but my remote still doesnt work =[ But are you saying that if i buy a stock 04 rx8 remote off of ebay i will be able to program it with my only exsisting key with the procedure he listed here?

like skrubol says
you do need at least one fob already programmed to the car to program an additional remote
at least two keys already programmed to the car to program another key (valet key would work if you have that, it is just cut a little different so that the trunk and glove box cannot be opened)
If you do not meet the requirements the dealership can program the key or remote with the WDS system that adds them to the ECU.
Who69, you'll need to bring it in to the dealer to have the key programmed to the ECU.
You can program the one remote as long as you have at least one other remote.
The key needs at least 2 already programmed, to add another key.
(just mentioned 5 posts before)

I just followed the programming remote instructions in the PDF or whatever it is at the beginning of this thread and used the new remote as remote 1. Worked first try iirc. To program the key I chose to get a valet key from the dealership rather than spending almost as much to have them cut/program my switchblade. In hindsight it might have been better to have the dealer take care of it, as I haven't been able to get a good key cut (first key wouldn't unlock door, had a hard time in the ignition. Second key works fine in ignition, but still won't unlock the door. If my remote battery dies I'm screwed.)

ok I just got off the phone with the dealership and they told me they can't program a new key without two keys either so I'd have to buy a valet key first which makes no sence to me cause they would have to program that right anywho they also said that they don't program remotes that I would have to order one from california customs so I'm not happy
