Must admit I prefer the look of the Bentley fob. I will hopefully be speaking to Jason tomorrow so will show him the picture to see what he says. That is an excellent effort Sally, thanks. I have been working on photoshopping that fob, but as this is the first time I have ever used photoshop I wasn't getting very far. As mentioned by Robbie the buttons will have to be in a similar configuration to keep the move from one key to the other simple. Changing the shape of the buttons should be a possibilty, aslong as the contact underneath can be made on the switch.
Will keep you posted after I speak to him.
