Oh, for that, you just have to really pay attention to the key light on the dash.

I just set up a new key and it did take a few tries to get the timing right.

 

Hmm, as soon as I left Home Depot where the cut my new blank switchblade key, it started my car fine. It doesn't actually work in my doors though lol.

 

I only tried may be three or four times on seperate occations. I have time tomorrow, may be I will experiment and follow the instructions in different variations

My concern is, I just can't remember if I had the blinking red key light on the the dash before I tried to link the transponders to the car or not. I still have that blinking red key light even after I have disconnected the car battery, as well as, when either keys are not in the ignition. My 2004 keys still work but I always have the whole switchblade key FOB in the car key chained with the 2004 key each time I am driving the car.

Could both of you tell me if the red key light is something pre-existing with the car or I may have caused that during my attempts to link the used switchblade transponder to my car?

I had a 2004 keychain FOB that stopped working and purchased a used 2005/6 switchblade, were yours brand new and own a 2005/6 RX-8? Likewise, my locksmith had that initial problem where the newly cut keys only work in the ignition then took him another half an hour going back-and-forth turning the key in the key hole and grinding the key until both newly cut keys worked in all the doors, trunk, rear pass-through door, and the ignition.

 

Just a general thanks to Grace and others for all the answers in this thread. I am ordering an eBay switchblade with the right FCC for my 04 since my OEM fobs don't work anymore even after I have replaced the batteries.

I'm sick of using the key to get in the door.

 

You're welcome! CR1625 is the battery for the switchblade FOB. Just make sure you purchase a Visteon not a Mitsubishi as a few members have mistakenly purchased.

Click on this link for replacing your Switch Blade Key Battery and the inside will look like this where the Visteon and FCC codes are.

 

Yup, got Visteon 41525 and FCC ID: KPU41788. I think I am good. I only got for the moment as I want to make sure I get everything to work first. I'll post up success or any issues. Right now the fob and key are in the mail.

 

Everything with the 05 switchblade worked like a charm. You rock Grace!

 

Hi.
I recently bought a 2004 model and I want to program the valet key. Lost the other key. Now I need a pin to do that. Can anyone assist with this, if I give the VIN?

Stranded!!

 

What did you do then?

 

If you had taken the time to read the primary pages, you wouldn't find yourself asking that question!

 

Sorry if that sounded lazy, I have been reading these pages back and forth now and it seems that the thing that solves this is to reprogram the key. I did it but it didnt solve the "honk when locking" problem..

 

If anyone needs a key made in NYC, Star Locksmith has switchblade blanks and will cut and program the key to start the engine and open the doors and trunk etc and the key works on the doors and trunk. Price was $160. Dealership tried to charge me $491 for what i got done in less than 10 minutes. I only had 1 key and they used a machine to program the new key to the car.

Tell them Juan with the Black RX8 sent you.

 

$160 is way too expensive. I bought the key for about $50 from ebay I believe and then went to my local dealer and they cut it for me for free. Took about 30 seconds. No questions asked.

Then I just had to program it.

 

Could some one tell me if FCC: # BGBX1T478SKE12501 keyless entry remote work for a 2004 RX8??

 

Hi there..I read through the pages but didn't seem to find an answer.

I have an 08 with the advanced smart key..i lost one of the emergency keys but still have the bigger part itself. I'm trying to figure out whether or not I can program a switchblade key to my car? I want to leave the credit card fob at home and use the switch blade instead.

Thanks in advance

 

We really wouldn't know. Many of us have a 2004/5 RX-8, if you end up purchasing a switchblade and have successfully programmed it with your 2008, let us know.

 

Has anybody successfully programmed a AKE remote using two working AKE remotes?
I understand the dealership is the only place that can program a second remote when in possession of only one remote but..

 

magixpuma, your basic steps worked for me the best!!! Although, I appreciate all of you guys comments on how to program an Mazda RX-8 remote fob!!!

1 sit in car

2 open driver door

3 put the key in move it
to lock to on
to lock to on
to lock to on

theres a small button in the door jam with a rubber stopper on it press it 3 times

now check that the door buttons still work and lock and unlock the doors.

then press any button on your key fob twice. now be patient cuz it takes like 5 seconds for it to first work.

MAKE SURE YOU DO THIS ALL QUICKLY!!!! 30 secs and under.

 

So my understanding is that I can just purchase the switchable FOB above KPU41788 for my 04 rx8? Do I get this on ebay? How much for this? I can go to ACE or such to get it cut? I have tried everything with the Visteon 41848 fobs I have (2 of them) They both have new batteries but do nothing?! And the FCC code I have is KPU41805. I Don't know if these fobs ever worked but per your message the one you specify is OK for for any 04 rx8?? Thanks for your info! P.s? I haven't been to Auto zone but per posts on here you can check to see if old fobs are dead?? Giving signal etc...maybe try that out. Thanks! Any info helpful.

 

Ok guys i have a 04 base rx8 and I'm lost, when I bought my 8 it only came with 1 key. I'm trying to program my key fob. I do the steps like your suppose to but nothing happens. After I push the door thing three times the car only locks then unlocks 2 times instead of 3. Am I doing something wrong??

 

Hi, I wanted to reinforce this message board. Both of my keyless fobs died on me, so I needed a new one. After searching this board, I decided to test out the switchblade keyless fob.

Mazda dealer told me that it wouldnt work on my car since it is a 2004 Rx8 (first generation). That was to be expected; however, a Mazda technician assured me that it would work flawlessly... I will just need to get it cut and programmed.

My died fobs were Visteon Model 41848, FCC ID KPU41805 (see the back of your keyless fob). I ordered used one off ebay for like 30 bucks, which has FCC ID KPU41788.

I had to get the blade cut, which home depot wouldnt do it. Went to a local locksmith, and paid 6 bucks.

Total cost was about 40 bucks... and I followed the instructions on this board to the Tee and it WORKED!!! The "longest" part of this project was the drive to the local locksmith, which was a ten-minute drive... and the whole programming (remote plus the key) worked....

By the way, you will need two valid keys (including the valet key... which is has a grey-colored head on the key)... If you want to get your key cut, do it with the master key since with the master key, you can open the trunk and glove compartment.

Anyway, best of luck to others... and MANY THANKS to others for the instructions/comments/assurances!!!!

by the way, the dealer told me... everything would cost me about $215, that was the discount rate.... locksmiths in my area would cost me in range of $85 to $125 to cut AND program the key.... I spent? about 40 bucks for the same result/outcome...

 

Have same situation as you Random Thoughts. I wish to get a switchable key from ebay. Any one you recommend? I believe all are same kpu41788? I have a 2004 grand touring rx8 with 2 keys. Who did you use from ebay? Then as I am reading get cut at ACE or WALMART. Any suggestions appreciated. Thanks.

 

You need the flip key fob with these numbers.
FCC ID:KPU41788
Visteon # 41788

It's the exact same FOB i have for my 04

Morning, matey.

I got mine from autoniz:
OEM MAZDA FLIP KEY KEYLESS ENTRY REMOTE UNCUT KEY KPU41788

The most important things are... make sure that there is a warranty and a chip in the key. You can usually ask a seller. I would not recommend you to ask a seller if it would work on ur 2004/5 Rx8, because they will likely say "no" when in reality it will work as long the blade key has a chip and u have two valid keys. Finally, you want to make sure it has a trunk button also.

As for getting it cut at ACE or WALMART, you might want to call either store and ask because I have been told that Wal-Mart has changed its policy on cutting car keys. I did not verify that information as the closest Wal-Mart is about 20-25 minutes away while a local locksmith was considerably closer.

I hope that helps. LMK

 

I followed the DIY procedures trying to program my Switchable Flip Key. I used my other 2 keys and followed the instructions on Mazda Money's GIFT (4 thumbnails). They both start the car and did make the car lock/unlock. I don't have to wait between doing each key do I? I did each key within 24 seconds. Then I inserted the Switchable Flip Key (with remote all connected in one piece..as it separates in center) and again followed the instructions. Turned 3 times and click on door side button 3 times etc. Doors opened/closed etc. It said to press 2 times on remote part of switchable key 2 times and it locked/unlocked drivers door. I got out of car and it unlocked drivers door but not passenger. Is it supposed to unlock both? I tried the trunk release worked no problem. Got back in car turned ignition and nothing. Is the Switchable Flip Key programed IN 2 parts?? It opened the driver door from outside..trunk etc but can't start car. How do I do this? I had 2 separate Mazda Steering Column Ignition Replacement Flip keys cut from blanks as extras (the top portion of the remote that separates) as got from ebay. I had originally purchased a complete Switchable Flip Key and had cut also. Do I need to clear codes stored? And info appreciated. I thought I was so close as think it worked all doors/trunk but can't start car with any 3 of these??

Thanks in advance for any help! I know these questions have been asked in forums etc on here but unfortunately I'm at a loss here.
