Techstream key registration

[m4rkw]

I've just got an aftermarket key that *should* be compatible with my 2006 Harrier. Unfortunately when I try to register it with Techstream it says "registration failed". Anyone got any tips?

The remote works fine but I can't get the transponder to register.

 The solution is in the CD but not legal 😇

Not sure what you mean, there's no CD involved here.

Anyway I found the problem, they sent me a key without a transponder chip so no wonder it doesn't work!

My 2005 RX300 had a 3-button key, the buttons controlling the remote lock/unlock and the transponder controlling the immobiliser. However, when taking the key apart to replace the Battery, there's only one electronics unit and all functions are done by that, so how can it not have a transponder in it?

They said that the harrier is usually sold without an immobiliser so they sent me a remote unit that doesn't have a transponder. They are going to send me a new one with the right chip in it though.
