Key change tokens
When your meter needs a key change, and how to enter the two key change codes.
A key change updates the security key inside an STS meter. It's needed after some repairs, a tariff change, or when the supplier updates keys for all meters.
How it works
- Ask support for a key change. We check the meter and the owner before issuing.
- You get two 20-digit codes by SMS. Enter the first, press Enter, wait for Accept.
- Enter the second code the same way.
- Now enter your normal credit token.
Enter the two key change codes in the order given, before any new credit token. A credit token bought after the key change is rejected until both codes are in.
