I've employeed several alternatives. Have installed mechanical trigger (open door) and glass break alarms, very loud alarms, which also notify my key chain if I'm not in immediate vicinity of deuce. Also, since the covered cargo area requires security I have installed a magnetic sensor, to sense movement either inside of the cargo area or close by, depending on how you set the sensitivity. You can set it so you hear a "chirp," for example, if you approach within 5 ft, and a loud alarm if you enter the cargo area. I am rarely if ever out of range, and if I am the deuce is secure in my garage. The alarm should chase them off, anyway (well, maybe). As additional safety measures I have "keyed" the ignition, and I have installed a keyed Cole Hersee battery selector behind the passenger seat. Nobody will find the switch if they are in a hurry and find there is no power because I routinely switch the selector to "off" when I shut down. Have redundant (2) 24 volt systems. Used the tool area and installed the same two deep cycle marine 12 volts in series as I have for the primary battery array. Also have redundant 12 volt deep cycles, one in each tray with the 24 volt series, with separate 12 volt alternator, to run all the lights and other fun stuff. So, really 2 Cole Hersees, battery 1, 2, both, or none. Just for muscle memory I shut them both off and lock each swich, when I shut down. The alarm systems are wired to bypass these switches. An old man. Just returned from Inuvik, NWT, by way of Dempster Hwy in Yukon. As far north as you can drive above arctic circle in Canada, during summer. We old men have to take sufficient precaution so the grizzly bears don't steel our rigs.
If you don't want to get paint in the lock cylinder than paint it with the key in the cylinder. When finished painting than remove the key and dip it in solvent to clean it.
