you can disconnect the arm linking the handle to the central locking meaning it would only open with the key - but why would you not want it to open with the fob?
I had issues with mine leaking and when I came to change it noticed the original key didnt fit the boot lock, so it was being run ONLY from the fob, bad news when the fob broke, and you have the dog cage bars fitted and on one of the seats that holds the dog cage the clip had snapped

it was time for some careful cutting with the biggest cutters I had
