Overriding code on a smart key

[wilcol123]

I have puchased on ebay a smart key for my 2009 Highlander and have been told by 2 Toyota dealers that a key programmed for another highlander cannot be reprogrammed for my vehicle. Is ther a way to override the original programm and reprogram for my vehicle. Where might such a service be available?

Check out some of our past threads regarding key fobs (like this one) that may have a solution to your question. The search feature is located to the upper right of the Highlander forum main page.

Doesn't sound right unless during the registration process something is changed in the key firmware.

Otherwise..

I total of 7 keys can be registered.
The key recieves signals from the transponder and returns the key ID code.

If you bought a new unregistered key you should be able to get it added.

If you bought a previously used key and Toyota has some logic that adds vehicle specific info to the key during the registration process you are out of luck

I bought a used HL smart key on ebay; however, the dealer also told me that keys cannot be reprogrammed for another vehicle. Dealers say they cannot do things (that they really can do) all the time, so I am very weary of believing them. There are all kinds of people (and 'companies') selling used Toyota SKS fobs online--- if it is not possible to reprogram them, then why on earth is there a market for these used fobs? I need some concrete evidence either way on whether used fobs can be reprogrammed to another vehicle. Any help would be appreciated!
