locksmith worked for me! a TON cheaper than the dealership too!

 

Dude just program it yourself. It's brain-dead easy as shown HERE.

 

Hey guys I'm going to purchase this transponder

http://cgi.ebay.com/ebaymotors/2005-...Q5fAccessories

But in the link it states that I need to use a scan tool, or a programming computer to make it work, are they just talking crap? Or do I really need to bite the big one and have the dealer connect it?. I know how to program it; but I just want to make sure that this key fob is ok

it is a KPU41788, which works for my remote KPU41805

 

The key has 2 different types of programming.
1. For the transponder, unlock doors, trunk etc.
2. This one, the key itself to turn the ignition, unless you already have 2 keys programmed and this is going to be your 3rd, you HAVE to go to the dealership and pay.

 

Oh I have two keys, I just wanted to know if that little disclaimer they had was serious, I know how to program both keys. I just wanted to be sure thanks

Just wanted to thank everyone who contributed to this thread. I bought one from Ebay and it programmed with no problem. As long as you have 2 working key programming is very easy. My problem was getting the key cut. I went to 3 different places until I could convince the guy that I know what I am doing.

The seller I bought my key from is remotez4less.

BTW if programming goes wrong or cutting the key goes wrong you can buy just the key blade and replace it.

 

What is the model #, FCC ID #, IC # on the remote? That ebay seller doesn't provide any of that information in his ad. 2004 RX8's will only work with a specific switchblade model.

Here is what I got: FCC ID: KPU41788 IC:4238A-41525 Version No:41525

That's why I put the sellers name cause the one I got from him worked for me with no problem. Also the reason I chose him was it was the cheapest on Ebay that accepts 7 days money back based on their ad. Even if you cut the key and find out it is not working you can buy one of these blank blades for around 7 bucks and return it or sell it on Ebay. Here is a link of one of these blank blades: http://cgi.ebay.com/ebaymotors/Blank...Q5fAccessories

 

ok i need help, i read this thread but i think i am misunderstanding. I have a 2004 rx8 and both of my keyless remotes are dead. They are the old ones with an FCC ID: KPU41805.

Question 1: If i get an uncut switchblade remote from ebay with a different FCC ID, will it still work with my 2004 rx8?

Question 2: After looking at ebay, all of the switchblade remotes say they only work for 2005+, if i purchase one of these switchblades remotes with an uncut key, will it still program with my 2004 rx8?

 

I have an 04 RX8 too. MY remote had the same KPU as yours, KPU41805. I bought the switch blade one from Ebay with different FCC ID: KPU41788 and it worked with no problem on my car.

The reason all of those says 05+ and the dealer says the same is because they come as 05+ and they do not know or try these remotes with cars. They just put whatever the manufacturer of these keys says. Switch blade was not available in 2004.

Some people say some of the keys on Ebay would not work with 04 cars. IMHO I think there is no reason it shouldn't work but to be safe buy it from a seller that have a refund policy just in case it is not working for you. Before cutting the key program the remote part, if it works then cut it otherwise return it.

If you look couple of posts above I put the info of the seller that I bought mine from. I just bought mine a month ago and they have refund policy.

BTW You can program the remote part yourself. You need to have 2 working keys in order to program the immobilizer part yourself otherwise you should go to dealer. Lastly the hardest part for me was convincing the guy at Lows to cut the key and I know it will work.

 

Thank you very much Khaf, I will purchase the key and let you know if it works.

 

im currently in a paypal dispute with "Remote Supply"

stay away from that seller. he would just keep your money!!!!

 

Can you please explain what happened? The remote is not working for you? Can you please post the FCC ID# IC# and Version# of the remote you received from them?

 

stupid stealership sold me a key (non flip key) for 50 something $$ and my key fob doesn't work either They kept on saying that the flip key doesn't work on my 04 and now I read this thread. I failed

 

that's the problem, the bastard kept the money and never sent me anything. the key that i bought was kpu 41788

 

got the flip key, programmed it first try on my 04 rx8, got it cut, everything works perfectly. thank you all very much.

 

I have an '04 (built '03) and only have 1 key (no fob). So I have to go to a dealer or locksmith and have them program a 2nd key so I can buy the switchblade and program/cut that myself?

Sorry this is a bit confusing...

 

I've got one working on my 04 and it's the official Mazda switchblade one.

 

programming yourself wuddn't work cuz you need at least 2 working keys to program a new key

step 1: buy key off ebay
step 2: go to dealer and let them cut + program, tell them to cut it anyway if they tell you it wouldn't work
step 3: enjoy your new key

 

can you still get a switch key cut if you only have one key?

 

yep

 

I know its been posted before, but what is the current part number/vendor? I looked up the numbers before without luck...

 

I just have 1 key and if I ordered a new key (KPU41805) can I still get it cut?

 

The same question have been repeatedly asked, if you scroll up, you will see the response by Khaf below.

 

I ordered my key today, only problem I have is that I have only 1 key so I won't be able to program the key myself and the dealer wants to charge me $150 to do it, does anyone know of any other place to get it programmed I live in Dallas. Please help I don't want to have to pay that much for something that can be easily done.
