How to make a duplicate transponder key?

[Exiwolfman]

No need for master key to program new keys but u need to reprogram ECU by obtaining a 6 digit code directly from Toyota this will wipe the ECU old security and reprogram with new with and new cut keys don't know why they are charging u so much tho it's about a 15 min procedure with tech stream online with Toyota plus cost of keys and remote.

Are you sure about that? According to the service manual, with no master keys in possession the transponder key ECU has to be replaced to add new keys. I know that when you buy a new Toyota you get a little metal tag with the keys that you are told "not to lose". My understanding is that code is just for cutting the physical key - It has nothing to do with resetting the transponder.

Hi wolfman,
Thanks for your useful information. How much will it cost generally? Dealership told me they have to order a new key from toyota for $165, together will other costs, almost $400. but the key is much expensive than ebay. could I buy a new key myself?
