the only problem is that I live in a small town so the only other dealrs are like 2 hours away lol

 

This thread is confusing. So if I have an 04' with one key, and I want to get the switchblade and key programmed then I need buy a switchblade remote and key, then pay the dealer $143.00 to program it?

 

You're telling me! I am starting to get confused.

The confusion came in when someone said they could get into the programming mode for adding the remote without having a previously programmed remote. I have never seen this happen personally, but also haven't tried because cars I have programmed already had at least one remote functioning.

For programming keys it is really easy as long as a person has two keys already programmed for the car. (see document at the beginning of the thread)

If a person does not then they will have to bring car to dealer to have the key programmed to the car using the WDS machine which adds the key to the ECU

Any of the advanced keyless systems (card remote) need to be programmed via the dealership. (Unaware of any way around this although eBay sellers have said that it is possible, in small print they say some systems may require that the dealership program the remote or key to the car).

Hope that helps clear some confusion.

 

well the key and the remote part of the switchblade have to be programmed separately right?

 

Right. The switchblade key just combines a key and a remote in one body, but they function separately.

 

Thanks.

 

hey so I've got a 2004 american RX8 and bought a 2005 switchblade key with FCC ID: KPU41788, IC: 4238A-41525, and Visteon no: 41525 from ebay. I was able to program the remote just fine even though I didn't already have a remote, but I can't get the key to program after many tries. I've been using one master key and one valet key. Any idea why I can't get this to work? im so frustrated with it cause I followed the instructions perfectly. thanks for any help.

 

nevermind, not sure what was up before but I've got it working perfectly now.

 

Hi Guys,

How do you get the remote control to open the trunk?

 

there's a button on the key FOB for it.
if it doesn't work press the button in the glove box to activate it.

 

The transponder is a static code passive type for the record.

You can use WDS to add a key with just one key, or use two keys to add a key, same applies to the fob too. Also JET has an expensive hand held device that will program off one key without the car. It does it for all static code transponder systems which is a lot considering only a few manufacturers use rolling code algorithms.

I use the 2:1 sequence method. I want to get the JET device though or another dynamic cloner. I'm surprised there isn't open hardware for it considering the popularity of RFID. These use standard frequency, but I'm not sure about the protocol.

The above applies to any year. I used it on a 09 recently.

 

man i got an 04 with fob, nethier of the remotes work

 

Just finished programming my new switchblade, thanks for the instructions OP.

Car: 2004
Key:
FCC ID: KPU41788
IC: 4238A-41525
VISTEON NO. 41525

I ordered the switchblade from a vendor on ebay, it came with a blank key.
It took it to the dealer to get cut. I provided the little aluminum key code tag, and they cut the key for free.

programming key: you need 2 working keys and one new key.

programming the remote: you need one working remote and one new remote.

and then i just followed the instructions on the first page.

 

2003 Rx8 i dont have any key i m in pakistan here is no mazada deller,
no programmer, wat can i do plzzz help me

 

You'd have to contact Mazda support and give them the VIN and proof of ownership and they will ship it.

There exists 3 methods for programming fobs and keys.

1. The 2:1 method described throughout this thread
2. The single key sequence method which isn't clearly documented for any year
3. The JET programmer that can clone off a single key even without a car, but is really expensive.

Various people are trying to be the authority on the subject matter within this thread, and it just makes it a headache for people trying to save money trying to self-service their vehicles.

 

Alrighty, got a KeyFob in today, and wanted to make sure the numbers are right.

Viseton Model 41805
FCC KPU41805
Canada: 4238A 12076

It matches my old remote numbers perfectly, except the canada part is TW and the model number is 41848. I can't seem to program the new remote, so I figured the number check was in order. :P

EDIT: I got it to work, it came with a near dead battery and it wasn't giving off enough signal. Works perfectly.

 

Hi all,
I have a Mazda RX8 2004 04 plate, the key fob stopped working so i took it to my nearest dealer, they tested it and said it was faulty and i needed a new one, i have bought 1 and was wondering if i need to take it back to the dealer to get them to program it or if there is anything i can do myself, i only have one ignition key and only HAD one key fob, any help/info would be great, i have tried the method in the threads on here but never seems to work.

 

How far do you get into the process before it fails?

 

All off it works fine until the press any button on the remote part, when i press any button twice there is no response, i have two remotes which i bought from cars that they both worked on with no problems.

 

do you know if you can use a snap on dtac to do this? I have a bunch of different diagnostic tools at work, but I don't think we have a Jet.

 

Just bought an 07 2 weeka ago but only came with one credit card key.. been reading a lot on how to program new keys and such but nobody can say how to do the dredit card one from what i have read. Is it all the same no matter what?

Do I have to have 2 keys like the 04 05 models...

 

Call mastercard

 

I need to if I ruin this one.. maybe I can get a magnetic strip put on the car like they have in high security buildings....

for real anyone know if I need 2 keys to do this or am i screwed and have to go to the stealership...

 

So I have done this procedure twice in the past with great success.

Today I program my new switchblade key for my newest 8 and when I do, it disables the other remote. Weird. So I do the process again and get the other remote done...and now the switchblade remote doesn't work!

So I do it a 3rd time and program BOTH. I think I found out why, the other times I had done it on previous 8s the other remotes were no where near the car. I am assuming if the other remotes are near the car and you program one, but don't touch the ones in range they become disabled.

I could be wrong but that would make sense considering what I just had to do.

 

I'm pretty sure the procedure requires you to code all FOBs that you plan to use at the same time. If you don't include the FOB in the procedure then the car no longer knows of that FOB.

If you review the actual Mazda procedure there's a "loop" you stay in for each remote.
