Yeah if there is no way you could pay the smallest neighborhood juvenile delinquent a buck to snake thru the back seat then yes drill it carefully so as to not torque/bend anything that you dont want bent. You might try & pick it by turning the cyl slightly clockwise with a narrow piece of cutdown hacksaw blade & holding that pressure then raise the tumblers one by one till they catch as you maintain the slight turning pressure. You might feel the cyl turn a hair as each tumbler raises enough to where is now in line & not keeping the cyl from turning. all of em have to be at the right height which why the key notches are at different heights. Good luck with it & holler how it turns out
