A well-cut copy should enter and turn without excessive force. Wear on the original key, profile type and cutting accuracy affect the result, which is why suitable professional equipment matters.
Before copying a key
Bring the original in the best condition. A copy made from another worn copy may reproduce faults. Some protected profiles, coded keys and remotes require a card, documents, specialist equipment or programming; compatibility must be checked in store.
Storing spare keys
Do not label a key with the full address. Give copies only to authorised people and keep a simple record in businesses or managed properties. Avoid predictable hiding places next to the door.
If a key is lost
If the missing key can be linked to the property or theft is suspected, changing the cylinder restores control over the copies in circulation. Electronic credentials may sometimes be removed from the system.
