My sister is at mine (About 50 miles from her house) and cant find her car keys. Not sure if she dropped them coming into house last night or when we went out for a walk. we have turned house upside down, retraced our steps from last night but no joy...Her house keys are in the car. She has no other sets of keys for the car, I dont drive and she has no docs with her...who is she best contacting? her car insurance? She is fully comp, and thinks she has keys covered but not sure! Advice appreciated as we both have toddlers and were just heading to a soft play centre when we dicovered we couldnt find her keys!
