Worthwhile product for security. Suzuki should include it. Shipped without instructions. Needs some experimentation to get the personal configuration right. Physical connection into the car’s harness is easy and does not look non-standard. On the automatic, one can have the option of auto locking when selecting Drive or when driving at 15km/ph +. Can’t have both options set. If after driving away, one of the doors is opened, it won’t auto relock. Auto unlocks when selecting Park. Feature which flashes the hazard lights if a door is opened with the engine running is a good safety option.
