Not an auto electrician , but will try to help .Could it be the relay sticking ? Also a few suggestions here about disconnecting remote control signal box for an hour to reset which seems to have cured some faults .Maybe worth a try ?

Its worth checking to make sure the fuse isnt linked to something else for example boot light.Then it will be a case of disconnecting each door lock etc.Do you have access to an amp clamp?
