Hi,
I have new 2007 Caravan base model which has no power door lock. I called a
local electronic shop about keyless entry, they say they can only add remote
keyless to front doors. Not for sliding doors and back trunk because there
no actuators. I wonder if it's too big a job to install an actuator? or it
costs too much and not worthwhile? I really want one for the trunk, so no
need to use key in cold days.

Thanks,

John
