How to make a duplicate transponder key?

[Exiwolfman]

Yes I have done one on a sienna ..same problem person lost all but one key no masters .
In order to do this I had to log with Toyota and its full of security as in they need my name , blood lol etc after that I get the code that basically resets the whole security and at this time u can load blank keys as ECU is reloaded but like I said only Toyota employe can do this and one has to be verified .
But this is completely different procedure from just adding keys with that u need master for simple add on of lost key with out special security protocol .

That makes sense. So, it's definitely not a DIY. I wonder if the OP's dealer is charging the $400 for that service or if they are doing the service manual route?

By the sounds of it they are doing the manual route and charging for something that just need programming with new security .

They said to order a new key for $165, and look for code/cut/program/, totally about $400. I think it cost too much.
