Moving the key is easy.
The question is, do you have a working key in slot 1,2? if yes, are they wireless?
If No,No, then you job will be:
- Save the key data from slot 4
- delete the key No1 from slot
- go to Option 3 and select slot 1, then load the saved file of the key data, then program it ( you may asked to insert a working key, you still can use the same key)
- go back to option 3 and delete the key on slot 4.
