Does the Transponder in the Key really work?
So I have a question but hopefully the title of this thread really explains it. Anyway when it comes to getting keys for my 05 RA they say I have to get a special key from the dealership and I'm like okay that seems sensible. A few weeks later my brother goes to Home Depot and gets a copy of my key and I still figured it'd be okay cause there's no transponder in the key. About 5 minutes later I hear my car driving off and now I'm wondering if the transponder really does anything? Can anyone enlighten me on this?

Certain models, especially the 04-06 Lancers and RA's, didn't come with a transponder. Most dealerships are lazy and don't want to try to figure out if it was one that did or didn't and will try to sell the more expensive key rather than admit mistake after they cut it and can't get it to code.

My lancer does not have a transponer. Not sure if the transponder is in the key or the key cylinder. Maybe someone with a transponder can shed some light. I do know from experience installing remote starters that some vehicles have a transponder chip in the head of the key itself and other vehicles have the transponder in the key cylinder/barrel. When a valid key turns the ignition cylinder it reads a transponder on the cylinder side and allows it to start.
An easy way to check would be to try hot wiring your car... hehe... just kidding.

From what I know there is a transponder in the key and there is some receiver in the key cylinder that receives the signal to start the car with the appropriate key. But now I'm having my doubts about whether or not I have one in the car.

If you can go to home depot and get a metal key made that starts your vehicle there is no transponder/chip in the factory key. most lancers that i know of dont have transponders on the other hand some galants and diamantes do.

Lancers ands Evo's are the only mitsu's that dont use electronic keys, so yes you have waisted 80$ on a "transponder key" witch doesnt exist for the RA and most lacers if not all. hope that helps

Evo's have the chips in them. The dealer had to replace my ECU at one point and when they did that they reprogrammed the key I had with me. The spare I had at home no longer works...the car will start up using the spare key but die within 3-4 seconds because the codes don't match.

It may not because the 2008+ has a valet key in the FOB with no chip

Yes, the key in the fob in your KOS (Keyless Operating System) is just a metal key with no transponder, but the key will not work by itself. The key fob must be attached to the end of the key while it's turning in the ignition cylinder in order for it to start the car. This metal key is there so you can start your car in case your FOB has lost its' program and the KOS is inoperative.

Confirmed, Evo's definitely have an immobilizer and all useable keys must be programmed at the same time or the non-programmed one will not work.

You can have your dealer program your spare key to work, so the key isn't a waste. Or if you have 2 keys that work already, you can program any extra keys by yourself. PM me if that's the case, and I can guide you through the method to do it.
