I bought a switch blade key, programed the remote and tried to program the key chip to cars ecu but no go. Main question, i believe the key may be cut a little off. Will a cut, being programmed key, turn to the on position from the lock but just not start the 8 due to the immobilizer ? When Im undergoing the key programming Im using 2 working keys with a 3rd being the switch blade. Any help would be great . Thanks

Now Geradenoz, once i finally found someone who would cut the key i also had to have them tweak the cut before it would turn to "ON". As long as your key will turn then your good to try programming. I was careful not to go past "on" though in fear of triggering some hidden security that would hinder my programming, just paranoia im sure. I also used my valet and it went fine, but i started with my primary key as key 1. I also paused on lock when turning to off since the directions noted "turn to lock". You need to do it all qucik too though, 4 seconds may seem long enough unless you fumble between key changes.

just brought the key back, wouldnt unlock trunk or door. I noticed i was a tad retarded for not trying it before. Imeaditly tried to program. After some fine tuning by the man we were in business!
Pro tip 101
** make sure key works in trunk and door tee hee !

So Question..
I've read all the posts and I'm not seeing my answer. on my '04, I have 1 key (Which to be the original I think.. bought the car used). I'm having a locksmith who says he can make+program a 2nd key.
1) Having 2 keys I should be able to make my own and program them? (1 not being original would work?)
2) The Key FOB Is the original but it's not programmed.. I tried the ON/OFF x3, Lock x3, but when I push the button on the FOB twice, nothing happens.. Any insight on this? Or do I need to goto the dealer.. (Not wanting to pay out the butt)
Thanks for any help!

One key will program the switchblade FOB, two working keys will program another key. The answers are in the thread, if you scroll up to the top, you will see the type of FOB needed for this to work. As I have explained before, the programming instructions in this thread is for the switchblade and WILL NOT work with the original 2004 OEM keychain FOB.
Here is the summary of everything (everyone) needed to know:
Here is the summary of everything (everyone) needed to know:
Read the procedure. You've got everything you need (except the switchblade and blank) to do it yourself with a quick trip to a hardware store to copy your existing (not valet) key to the blank.
The valet key definitely works as part of coding -- just don't use it to cut your new key. And you do not need an existing FOB. They all get re-registered when you follow the specific procedure for them... again, documented above.
The valet key definitely works as part of coding -- just don't use it to cut your new key. And you do not need an existing FOB. They all get re-registered when you follow the specific procedure for them... again, documented above.
You need AT LEAST 2 keys that are already cut/programmed (this can include the valet key) to program another key, after having it cut.
If you don't have 2 keys already that will unlock/start the car you will have to get the new key cut (anywhere can cut the key so it unlocks the door) AND you will have to get it programmed so it will start the car. You can get the programming done at a dealership or at select locksmiths.
Once you have those 2 programmed you can program another.
If your FOB goes bad you don't need any working ones to program the new one. All you need is ONE functioning key (fully functioning, unlocks and starts car). Use that key and follow the procedure to program the FOB.
If you have an '04 you CAN buy the switchblade FOB with FCC ID: KPU41788. It will program correctly.
I hope this is a reasonable summary for those reading the thread.

Grace,
Thanks for the response, I got the key programming part, Not really an issue. I ordered the Sweet switchblade and will try and program it when I get it. Thank you for the summary!
Although maybe I'm going full tard on this, but I see "This programming does not work with the Stock/original FOB. Are there no handy instructions for the original? Tried the one that says it doesn't work.. which doesn't.. obviously.
Once I get the switchblade in and if it programs the old one will be a spare if I can get it to work so I guess I'll be crossing my fingers for it to work lol

The 2004 OEM FOB may be programmed by the dealer's M-MDS(Mazda Modular Diagnostic System), I believe. That is why most opted with the switchblade instead of trying to reprogram and reprogram the 2004 OEM FOB. It happened to many members when the FOB battery started to die down, after replacing it with a new one the FOB failed to work.

The 04 I just bought came with just a key, no remotes. There are quite a few remote switchblade keys available on Ebay but some of them say they only fit 2005 and up. The few that fit 2004 like: For Mazda SKE12501 New Flip Key Keyless Entry Remote Fob Transmitter Replacement | eBay do not have the trunk button. Can I use the ones listed for 2005+ like: 2x Flip Key Keyless Entry Remote Fob For SKE12501 Uncut Transmitter Replacement | eBay with this 2004? I asked the seller and they said no but they may not be sure either. I obviously don't have the FCC ID number to compare it to.

I have a similar problem and searching here has not lead to a fix! My car refuses to accept any key fob. I've tried several from eBay, both of the common models. I've even tried a spare "switch blade" style from my fathers cx7. I don't have the flashing key that most people with bad antennas have. Does anyone have any ideas before I give up and just run with a key?
Edit. 2004 rx8 GT. Not the original engine if that makes a difference.

Make sure you have the right Model.
Old 2004 FOB:
Visteon Model: 41848
FCC ID: KPU41805
IC: 4238A-12076
What you need to buy:
Visteon Model: 41525
FCC ID: KPU41788
IC: 4238A-41525
All the necessary information of what kind of Visteon Model to purchase and the programming instruction I have already linked in this thread alone. I guarantee that the switchblade will work, specially if your 2004 originally came with the key chain FOB.
There are a few that have accidentally purchased a similar switchblade FOB but it was made by Mitsubishi. As long as you matched the information I have linked about the switchblade FOB, what you have purchased will surely work. If in doubt, there is a way to separate the FOB and the key transponder from each other. Inside is where the matching FCC and Visteon model numbers are located(see my picture below).

As I said. I have tried Both of those models. I also tried a spare switch blade. I don't have any of the other issues I've seen people say they have when they have a bad antenna. At this point I can only guess that the car has had 3 fobs programmed and I can't find any way to make it forget one.

I'm honestly at the point where I think there may be something wrong with my cars keyless system. It goes into programming mode just fine, but I've tried 4 different fobs, even the one the dealer said should work.

Can’t believe it’s 5 years later and I still need to post here about these issues! I got a new switchblade on eBay for my 2004 and I was successful in programming the FOB. https://www.ebay.com/itm/312756307539
Getting the new key to start the car is still not working. I had the key cut at the HD and it works on the door, trunk, and ignition. It won’t start the car though despite trying the registration procedure about 10 times. Everything goes as expected except I get the key icon rapid flashing when I introduce the new key. I’m starting to think that the RFID chip inside the switchblade is malfunctioning. Any other ideas?

I got mine cut but not programmed.
I think that's a job for the dealer, sad to say.
I could be wrong.

Several people on this thread stated they were successful with the procedure Grace_Excel posted a few times. It just seems to be hit and miss and my best guess is that it’s due to the low quality chips inside the switchblades we all buy on eBay. There are comments there from buyers stating that even locksmiths with specialized tools can’t always register them to the car. But as you said, my main need was to get a working FOB so at least that’s working.
