All you needed to do was an Ebay search: "Mitsubishi Evolution key" I think there is only two vendors selling them; one being expensive, the other cheaper.

This is what I found on a quick search and I think this is the seller that I bought mine from:
2006 Mitsubishi Lancer Evolution Transponder Key 8D4D

Good luck!

 

^got it thanks!

i tried searching the following key words:

evo 8 key
lancer oem key
etc etc

transponder was the word we want!

thanks sir!

 

No problem! Didn't know you tried searching, sorry. I know its sometimes hard to find stuff on these forums without searching using the proper words/settings.

Let us know how it work out for ya!

 

^hey sorry to bump this up.

i recently bought a set of remote and key. they are the same ones found on ebay. i was able to program the remote sucessfully. i havent had the key cut just yet.

can anyone tell me how to "program" the new $15 ebay key with transponder without calling locksmith?

edit: actually, nvm. i found a locksmith. hopefully they dont rape my wallet.

 

any diffrence from the ones listed as ID4D or 8D4D ? edit never mind just going to go with the 8d4d since thats what you listed i dont think there is any diffrence tho.

 

Can you not program the key yourself? When i bought my car it only had 1 key with it and I am going to install an alarm and remote start and have to have a extra key for that also. If I can get out of pay to get it programed that would be sweet.
