how do you remove the door lock actuator on the rear doors of a jaguar s-type on 2006 Jaguar S-Type

All the time, hit the remote button or the unlock button and you hear the actuator running but it does not unlock

Basically it's tedious hard-to-access component removal and taking it all apart. There is limited space to work inside the door, and you have to take both inside and outside door handles off, linkages off, unscrew the actuator and remove it. That's over simplifying the situation, but there is no "trick" -- just labor, access and removing parts.
