Most of the time you can lock and unlock the drivers door with the key to disarm the system.

if you use a regular key it will turn the ignition on, it will engage the starter motor & turn the engine over but if the vehicle has an engine immobilizer it will not start.....hope this helps......cheers.

of course it is from the battery but the flashing kleds take such a minimal amopunt of power to work you have no worries about draining the battery

Oil sludge or black sludge is a solid or gel in motor oil caused by the oil gelling or solidifying, usually at temperatures lower than 100 degrees Celsius. Sludge can be a major contributor to Internal combustion engine problems, and can require the engine to be replaced, if the damage is severe. Sludge is usually caused by the presence of water in the oil, and can accumulate with use. Ways to minimize sludge production and accumulation includes performing frequent oil changes, using synthetic oil, and following the manufacturer's engine maintenance routine.
The following engines were reported by the Center for Auto Safety and/or their manufacturers to have a problem with sludge accumulation:
