Large amount of house keys

A box full of house keys was stolen from house in Virginia, Co. Cavan. Box was found in Raheny so keys somewhere between Virginia and Raheny. Several bunches with coloured key rings marked "Upstairs" "Apartment 1" "front door" "back door" "no 3" etc etc. Also small brown pouch with 3 house keys on one ring. Some electronic gate zappers also in box. Probably all dumped in one pile.
