I've just (yesterday) purchased myself an '01 Hilux Workmate. While it's such a great, practical vehicle all round, the thing that strikes me immediately is how vulnerable it is to break-ins. The vehicle has obviously already been broken into at least once. The key for the door is different than the ignition, and there are scratches on the inner door lock. I'd like to know what options there are available for security for this vehicle. I'm assuming I can get an engine immobilizer for it, and probably not much else. How about an alarm for window breakage or door opening? Central locking??? Highly doubtful.
