After the problems with this stupid remote system and having no mechanical key I wanted a way to get into the UAV to at least charge the dead battery without having to crawl under, remove the splash pan and connect the charger to the starter. "dealer" wants $200 for a mechanical key, Found a wholesaler that had them for $170 but still expensive. carandtruckremotes has blank keys for $6. Pulled the lock cylinder from the door. There is a circlip on the end and wire retaining ring around the body. Take both off and the end comes off. The pin that keeps the barrel from turning can be pulled out. Reassemble the lock, put it in the door and now if you have to get in, snap off the cover and use the blank key or a flat blade screw driver.
Is it theft proof? No, but how many thieves go around checking if a Volvo had its mechanical lock modified? A thief would slide hammer the lock and use a screw driver.
Still needs the RFID pill in the remote to start the UAV.
