add) a used Smart Key that has been previously registered on another vehicle. after some additional research on the web and in the forums, here is the skinny on registering Toyota Smart key Has anyone gone through this process on a 2012 toyota? Did you get a seed code? If so, how did you get the passcode (did you find a calculator, send to the guy in the EU, some other source?). If I hit the copy to clipboard button and past into notepad, I get nothing. the box where the seed should be is blank. There is mention of some online calculators, but I couldn't find one.Īnyway, When I go into the menu to get the seed code. In order to do that you need a TIS passcode which is made from VIN and a SEED code you get from Techstream. If I go into Door Lock diagnostics to test the extra key FOB, the car does beep (telling me the key is xmitting but the car is saying it's not registered).Īfter some research, it appears that you need to 'reset' the ECU. I tried erasing one of my original keys and reregistering it, that process worked fine (so I know I'm doing the registration process correctly).
However, when I try to register the extra key fob, it isn't recognized (get the message 'key registration failed'). The Techstream tool works fine, I can get into all the menus and work that magic. I bought a used Smart Key FOB (HYQ14FBA) as well as the Techstream tool.
