Our garage gets used quite a lot, and the key tends to stay in the back door lock, day and night.
A way around this would be to fit a keypad combination lock, similar to those you see in offices, so that the door locks automatically every time it is shut, and the frustration of returning to the house to look for the key is avoided.
Has anyone heard of such a lock that is suitable for external use, ideally costing less than =A3100?
