Hello everybody.

Firstly, I must apologise to all those who have purchased these instructions from me over the past few months.

From May this year, Ebay revised their Downloadable Media Policy & decided to ban all digitally delivered items. This meant that the instructions that I have been successfully emailing to people were now banned from being delivered by email. I could have elected to print each set out & post them to buyers, but to be perfectly honest this would be both time consuming & an unnecessary use of resources (printer ink, paper, envelopes etc.) so I decided to simply stop listing in order to be a good boy & comply with the policies.

Unfortunately, not all members are as good at sticking to the rules as myself & several are still listing on a nudge, nudge, wink, wink, "I won’t actually state that I email the instructions even though I do" basis. This guide is dedicated to these members.

It would seem that the only way to make sure everybody sticks to the rules is to make sure that the information is made available to all, so rather than paying for the instructions to be emailed, here they are for free:

 

These instructions are applicable to the flip type rectangular keys – the "bladeless keys" can only be reprogrammed using diagnostic equipment & can NOT be used on any vehicle other than the one that it was supplied with.
