Parts apparently not available

I have a Toyota Hilux which is fitted with a Toyota Spare Wheel Lock Kit (Part No-PZN33-D 2010).The key for the lock kit has unfortunately been mislaid.However,when the Lock Kit was fitted by Toyota,a Key Code Card for the Spare Wheel Lock (which contains a special code number attaining to this specific Wheel Lock) was also supp**** and on this card it also states,quote,If you lose your key, hand this key code card into your Toyota dealer who will order a replacement,unquote.<br> When I approached McCarthy Toyota Centurion Parts Department I was informed they could order me a new key but I had to supply a copy of my I.D.document as well as a copy of the vehicles Registration Certificate to verify that I am the lawful owner of the vehicle concerned.<br> Upon my return to McCarthy Toyota Centurion with the correct documentation a few days later,I was now informed by the Parts Department that I could not just order a new key (they do not supply just the key)but that I would have to purchase a whole new Spare Wheel Lock Kit.<br> Firstly,I do not believe they cannot order me a new key as it is a Toyota product fitted by Toyota.<br> Secondly,I am in dire straits as I cannot remove my spare wheel.<br> <br>
