poppers, or remote latches that are hidden.
Poppers are inherently annoying. I am currently doing a 66 T-Bird shave project, and an lucky enough to have door latches that " PULL UP" off the latch release. I will be drilling a hole 1/2 inch away fron the window channel and using a bike BRAKE cable and a ringlet, a release wgen the door is "keyed" (yeah leaving the door lock is important in this operation) OR I will be using a simple design of some custom billet "chromed door latch knobs" on the outside and a "J" hook woth threading on it ran through a grommet in the door to match up and simply be a "PULL" rod through the door. it will look great no-matter what.
I will post pix this month as it is in the shop now.
FWIW< DO NOT RELY ON ELECTRICAL DEVICES TO LET U INTO YOUR CAR.... A BUSTED WINDOW sucks. So does locking yer keys in a DEAD BATTERY CAR.
