The key dance saga..

[Ac1962]

Hi all, be gentle please, my nerves already shot to bits over this...
My car 2002 PFL
i had one key, so bought a blank and a 'used' key to make a spare... the used key i bought i think now despite looking the same before i opened it up, has different internals so when i do the reprogramming dance, although the car goes into programming mode, the 'new' key refuses to play ball. Yes the battery is ok, i see the red light when i press the lock or unnlock buttons. So, am i right in thinking the internals make a difference and they dont all work regardless of car age? If so, does anyone have an old 2000-2002 PFL key with working internals i can buy? Also, if anyone with a requirement for internals from a 736716-A 2 button fob, please let me know

Our key internals are the tokai rika variety, Toyota did use three manufacturers so you may have got the wrong one.  Tokai are often grey plastic with a transparent battery cover.

Once you know you have got a tokai fob, the dance can be a little tempermental with the time between button presses - a watch of a youtube video can help.

Fob will also not pair if the remote already has four fobs paired to it - another dance sequence will tell you how many are registered.
