# ReplaceKeys

## Description

ReplaceKeys is a request to change the keys on an E-meter. The request needs the DeviceIdentification, an AuthenticationKey and an EncryptionKey.

All requests have similar response behaviour which is described in [ResponseMessages](/gxf/domains/smartmetering/responsemessages.md).

[GetReplaceKeysResponse](/gxf/domains/smartmetering/smartmeteringws/configuration/getreplacekeysresponse.md) returns if the result is successful from the ReplaceKeys request. The response contains the DeviceIdentification and CorrelationUid which is received from the ReplaceKeys request.
