The plan was to add another key to each vehicle and then put them in the safe after I got some switchblade keys.

The problem:
When I bought my 2004 RX-8 GT, it only came with one key; I wanted to program a 2nd, and a 3rd to the car because it also did not come with a FOB so if I was locked out, that would require pop-a-lock. Everywhere I have read, it says that I absolutely needed two programmed keys to program another myself. Option B was to bring it to the (st)ealer and have them do it for more than 100 bucks per key.

The key:
Mazda charges quite a bit more for our transponder keys so I did some research to figure out what is compatible aftermarket, and I purchased two keys off ebay for ~10 bucks each. The link is below but it may become invalid some day so here was the description: "Transponder Chip Ignition Key Uncut Blade 4D-63 For Mazda 2 3 5 6 CX7 +9 MX5 RX8" and the description states: " Manufacturer Part Number: BMZ24TK14 MZ24TK14"

Now go get that key cut while you gather the other tools needed...

The tools:
- ELM327 Bluetooth OBDII Adapter: These are cheap, I got mine off ebay for ~8 bucks to the door. Wired would work also, probably wifi versions that are compatible with iProducts too.
- A PC with bluetooth (option 2, wired adapter, wired to this pc, or wifi).
- FORScan OBDII software for the PC (the android and iPhone versions do not have the features you need to do this, but they have other capabilities that I will discuss later). Note, currently there is only a BETA version that works, make sure you read through the process notes below.
- FORScan's (currently free) extended license.
- Access to a website to decode the outcode and turn into an incode (this is discussed within the FORScan instructions, and its currently free as well).
- Your original key and the new cut key.

The Process:
I am a FORScan user, I use it to monitor various OBDII sensors. FORScan beats the competition because it easily allows me to access all the buses, this feature was not so simple in other softwares like Torque, etc. FORScan is designed for Ford, Mazda, Lincoln, Merc, etc. So all the PIDs that are available are already in the software. No need to mess around with adding separate pids. I've been using it on my Android and my windows pc tablet for a while now. Recently, I learned that FORScan for the windows pc supports PATS programming and also the RX-8, this is the feature that programs keys. So I took a challenge to overcome the Mazda costs and use this to program a 2nd key.

The first time I tried this, I had an error pop up that PATS programming is not compatible with my 2004 RX-8 saying because I had a push-button start. That is false so I contacted the support for FORScan and they worked with me to resolve the issue, then release a BETA version. This version is v2.33 and can be found here:
http://forscan.org/download/FORScanS...st10062016.exe
^^^^ Currently this is the only version that does not give the initial error. Future versions will work fine and I'll do my best to update this thread.

Running through the FORScan PATS programming process here:
FORScan forum ? View topic - How to program PATS using FORScan v2.2.*
I did not erase any keys, I went to the spare key program option and followed through with the instructions.

Note Problems faced:
During the programming portion, the software told me that the key programming failed. I reported this and it was explained to me that the OEM key is 40 bit and some of the aftermarket are 80 bit, which would cause an error. I went to module initialization after that thinking my key was still unprogrammed and did that with success but I don't think that was need. I then noticed the anti-theft light disappeared from my dash with the new key, meaning, my new key is programmed!!! SUCCESS!!!

After this, I did the factory 3rd key programming sequence and that worked fine. I now have three working keys, 2 of which are aftermarket keys!

Important little tidbit:
This saved me a ton of cash as you can see, I offered to donate to these guys but they don't accept donations. Their turnaround support time was incredibly fast (within hours I had a new version of the software)! Therefore, I want to do anything I can to give them a heck of a high-five...

If this works out for you, buy the phone version or a paid version when that is available, its cheap, that is the only way to support them at the moment. Links to follow:

FORScan v2.33 - test - 10062016 version that works with this process

I have two working keys, 1 aftermarked with chip i want to program so it could start the car.

The only thing different that I did was that I used a connected cable, same one that I use for my Toyota Techstream programming.

Thanks, OP, you saved me a lot of money!

I bought a 2006 mazda 3 sport a few months back, but it only came with one key. A few days later, my son managed to damage the transponder chip in the key when he dropped them onto a concrete floor from about 2 stories up. I was kinda screwed at that point, and had to fork out over £200 for a locksmith to come out to my house and to 'attempt' to reprogram a couple new keys. I say attempt, because he wasn't wholly successful. He replaced the transponder chip and managed to get the original key working again, so I was back to one fully working key. He then went to pair the aftermarket key he cut and paired to the ecu, but was unsuccessful. I was out with him and he even rang a few other locksmiths to see if they could shed any light on the matter, but to no avail. He was trying to pair it using the ignition/door sequence but it never got past the point where you add the new key. He said it was something to do with not having two central locking paired keys, as you have to click unlock on the main fob and the second fob before you can start adding new ones. Basically the key is paired insomuch that it will start the car without any issues, but the remote central locking doesn't work. So to use the second key you have to manually unlock the doors which sets the alarm off, and then quickly put the key into the ignition to silence the alarm. I guess this is kind of opposite to the problems some of you were having...
It's been like this for a while now, but I'd prefer to have at least two fully working keys. What I'm asking is, with the guidance outlined above, or by contacting forscan, will I be able to pair the coded and cut aftermarket key so that the central locking works on it? The locksmith said that the key he used they use for a variety of vehicles and that he's programmed it to tell it it's a mazda key, so it should be on the correct frequency. Its just the part of trying to get the ecu to accept the new fob that I can't seem to do...
