Things you'll Need
1.

$14 Keyecu Upgraded Flip Remote Car Key Shell Case for Toyota Sienna Highlander Tacoma GQ43VT20T,Just a Key Shell

Keyecu Keyfob Shell (This has a blank on it, along with a mock button set for dropping in the fob buttons I'll explain later)
2.

$13 KeylessOption Key Fob Replacement for 2004-2018 Toyota Tundra Tacoma Sienna Sequoia Highlander Remote, 3-Button GQ43VT20T

Tundra keyfob (You don't need this specific one, you can get one from a locksmith that works on vehicles)
3. Immobilizer Chip (This is the one that works for Dot key Tundras)

Steps
1. Dissasemble the Keyecu fob, should be one screw on the back. (There is a spring in there so be careful, don't loose it. Nor the screw it's very small)
2. You'll need to take the key blank and an existing key to your local locksmith and have them cut a clone of the truck key, then test it everywhere. Door locks, bed locks, glove box, and even ignition. Without an immobilizer, you'll spin the engine indefinitely without starting but it'll show that it will at least work.

3. While you're there, have them program your lock/unlock fob and confirm that the doors cycle locking.

From here, once you've gotten your immobilizer chip it's time for assembly.

4. Using a key, separate the keyfob and pull out the chip with the buttons, it should all come out in one piece minus the plastic.


5. Drop this in the slot on the KeyECU remote, it should pop in the same way it came out of the old fob,

6. Slot the Immobilizer chip into the small rectangular pocket near the top of the key, I would use super glue to hold it in place unless you like listening to your key rattle for the rest of its life. (The chrome is pointed at the immobilizer pocket.)

7. Reassemble the key itself, In case things fell apart, it goes spring, chrome tube, and the finalized cut key.
(The button has three wings, the two on the same side should be facing up) Also, Try twisting to have more tension on the key, it'll help it swing out faster.

8. More Steps coming together.

Nice DIY

Probably the only thing I really miss about my old audi, fun to fidget with.

 

I know it's an old thread, but maybe you'll respond. Did you need to get the immobilizer chip programmed as well?

I also looked as the link is broken, but is it a 4D-67 Transponder Chip? Thanks!

 

I have a flip key.
A local locksmith did it for me, $100 including key.
3 locksmiths told me it's not possible before this guy did it.
IDK why so many say it's not possible, maybe it's harder or maybe they truly don't know it's possible?

 

Hmm, I was planning on doing this myself. I've already got the shell for the flip key. Plan on getting some normal aftermarket "dot" keys and programming them via techstream. Then I figured I'd take the newly programmed key and cannibalize the transponder chip and swap that with the fob internals into the new flip "shell"

 

I didn't mean to suggest anything otherwise, I just wanted to share my experience and offer an alternative solution. IF I had the ability to DIY then I'd take that route!

 

Ah I see, sorry I was misunderstanding. Well I'll give the diy a shot and if I have some success I'll post up here

 

I bought the flip key shown by OP, it lasted a year and broke. Then I did the same thing, took its G code chip and dropped it in new case, and programmed door locks with Techstream as the PCBA was different...

This thing is solid. The blade swapped from broken flip key to so there was zero cost. I have thread somewhere here...

oh here it is
