well first im hoping that this is in the right section

well for the past few months ive been rebuillding a wrecked 07 mazda3s GT Hatch and am getting the rest of the little things together.

Right now i only have one key that works for everything. I would like to get one more key, maybe 2 and also a key fob, just a regular one to unlock and lock or whatever. Ive searched on here and could find a lot about the flip keys but nothing about the standard fobs really. I dont really wanna spend 120 dollars on a key fob, and ive found a few on ebay that say will work but wanted to check with this community first to see if they do....some are here

Ive programmed these before on other cars but i seen that you may need 2 keys to do it for mazdas, so im sure i will need to get the keys made before i can use the fobs. can i get the uncut keys off ebay too, i know they need the transponder but do those need to be programmed too?

Any info will help and thanks in advance!!!!!

you can get blank keys on ebay, the normal ones have the transponder in the key. (PATS transponder) you need 2 keys to program a third or more keys. if you only have 1 key you have to take it to a dealer to get it done.

as for the remotes i'm pretty sure you don't need an original one to program a new one, you just follow the standard programming method to add them.

so basically for me to get anymore keys as of now would be to go to the dealer to get another key programmed right, could i buy this key from anywhere if it has a transponder?

To link a new key to your car's anti-theft system, you need to have two existing keys. But to link a new remote, you only need a working key (not an existing remote).

As other have said...

To program more keys you need:
-two working keys

To program remotes you need:
-a single working key

Both walkthroughs are linked in my sig. ;) There's no problem with buying an uncut transponder key online, just make sure it has the chip in it. You can also get them cut and shipped to you from onlinemazdaparts for about $22/key. The dealer will have to program at least the first new key for you, but after that you can program a third one (and I highly recommend you buy a third one so you don't have this problem again.) As for remotes online just make sure you get the visteon and FCC numbers off of a 2007 remote and compare them to the ebay one before buying. Many ebay sellers will list a remote as compatible with all models/year ranges when that's patently not true.
