Hi guys... I received my switchback key from the mail today. i was so excited that i transferred the internal components of my stock key to the new switchback key. As i was about to pry the transponder chip from its place, i was surprised that it was not easy to remove it from the shell. though i carefully pried it off from the shell it still sustained scratches coz it was pretty much glued in its place. it ended up that i need to put more force to pry it out and ended causing a deep scratch with transponder. upon close inspection, i notice a shiny thing from the deep scratch. i was so scared that i might have damaged the transpoder, i replace everything back to its original places. then i tried to start my 4.4 with the reassembled key. and my 4.4 did not start. i tried it with the spare key and it started right away. at this point, i assumed that i caused to much damaged on the transponder chip thats why the car did not start with the reassembled key.

i accepted the fact that i already messed up one of my keys. can anyone give me advice on how to fix it (if it is still repairable) if not, help me get a new set of key that does not cost me like those bought/ordered from the dealer? or is it possible to buy a used key and reprogram the transponder to work with my 4.4? i badly need help with this matter. :crying

Yes, if you can find a used key on Ebay, you should be able to remove the immobilizer chip and reprogram it to your car with Techstream. Or you could go to a good locksmith and have them reprogram it.

This video will show how to get the chip out of a valet key:

I went through this process when I moved my key to a flip style key shell. The transponder chip on the side of the key is just nasty to remove, what you want to do is get a set a curved pliers and pull on either side of the housing. The transponder only is glued in from the top. Some solvent to dissolve glue is also a good idea.

Regarding the transponder itself, you sadly cant buy it stand alone, I checked at a dealership. It only comes with a key. What I ended up doing was purchasing a used Rav4 key off ebay. The US and Cad transponders are the same, but not the keyless entry remotes.
