So I took a little break from the headlight stuff to work on this little number:

Image


It's a Mitsubishi switchblade/flip key (or whatever you wanna call it) originally meant for the older generation Lancers (they don't make one specifically for our car). But with a bit of modification I got it to work for our car! The only thing is that I did have to give up the trunk and panic buttons though as the shell case only has two buttons; one for lock and one for unlock, but I thought it was worth the cool factor of this thing. Anyway I think I might be the first to have done this, so here are some pics of the process:
I started taking pics when I was already halfway done, so some things will have already been completed beforehand.


Nails removed from the back so that the shell case can be disassembled.
Image


Shell case disassembled.
Image


Backside of the front of the case. Had to shave off some inner plastic pieces that was meant to hold the Lancer key fob in place.
Image


Spare key that i'm about to hack up.
Image


Key taken apart (keyblade had already been grinded down/trimmed for the flip key and part of the key fob had already been trimmed/shaved off...ended up discarding the red plastic piece altogether).
Image


Key fob taken apart...here's the tricky part: the rectangular piece running diagonally on the top right is the transponder. This is needed to start your car. It has to be within a few centimeters of the ignition cylinder in order to communicate with and start your car. It is glued and soldered into place and has to be removed. There's a spot allocated for it at the very top of the shell case as you will see later. I stuck a piece of electrical tape on the bottom to indicate the negative side of the transponder.
Image

Image


The transponder has to be connected to the circuit board, so I used some 30-gauge wire to connect the terminals of the circuit board to the corresponding terminals of the transponder.
Image

Image


Now if you'll notice, the flip key shell case has the lock and unlock buttons in reverse order in comparison to our keys (ignore the lack of a transponder).
Image


This means that key fob will have to be placed upside down inside the shell case in order for the lock and unlock buttons to work correctly.
Image


The two buttons (lock and unlock) on our key are spread a bit further apart than that of flip key, so I had to adjust the white rubber piece of the key fob in a way so that the flip key buttons would be able to hit them squarely.
Image

Image

Image


I then placed the circuit board back into place, and here you will see the little spot on the top left allocated for the transponder.
Image


Put the back of the key fob back on (again, ignore the lack of a transponder).

Now for the keyblade part: you'll notice there's a little hole at the bottom of the left piece...inside is a small pin, it holds the keyblade into place. It has to be removed in order to remove the keyblade. I had to hammer it out using a small nail and hammer.
Image

Image


I then used a dremel and grinding stone to grind down the bottom part of the keyblade from the spare key I hacked up earlier and matched it with the bottom of the flip key keyblade.
Image

Image


Stuck the modified keyblade into that piece and hammered the small pin back in its little slot.
Image


The reason I didn't use the keyblade that came with the flip key is because it's not the same as the one for our car, so getting it cut is not an option. You'll notice the grooves are on the opposite sides (top: Eclipse key bottom: flip key)
Image


Now I reassembled everything back together and tested it out and voila! It worked perfectly!

...only problem is that I couldn't get the key out of the ignition! :facepalm:
It would get stuck on the ACC position and wouldn't go further down to the LOCK position so that I could pull the key out. Basically I wasn't pushing the key all the way inward in order for it to turn into the LOCK position as the shell case would get in the way and hit the ignition cylinder when I tried to push it in. So I had to disassemble the whole case in order to get it out. The keyblade was too short, I needed a longer one.

I had my key duplicated by this amazing key guy who's duplicates all kinds of automotive keys. I trimmed and grinded the base down to match that of the flip key.
Image


All three keyblades (left: flip key middle: OEM key right: duplicate key)
Image

Image


Finished product.

Oh, and the flashing red LED still works too! :biggrin: Vid of it in action:

Got mine off ebay, username : shopatomik. Item : 3 button flip key fob Mitsubishi.

Flip key blade is slightly longer than solid oem fob. Get it cut at locksmith. The dealership parts people are seriously retarded and dont listen /know how to cut keys properly. Monkeys can push a go button too.


Attached are the pics of flip fob vs solid fob. You can keep your trunk button woth this one and STRAIGHT SWAP. If you do want to rewire as thread discusses there is a spot to slide the transponder into, opposite side of. Flip button. I don't see why you would want to tho.


Buddy from ebay is located in America not China, it cost me 45 Canadian shipped, American is like 30$ if that.
