After Upgrading to KRN 2, My Prepaid Meter Will Not Accept New Tokens

After Upgrading to KRN 2 I get an Error 017
How do I know that I entered my Key Change Tones Successfully
Why you need to keep those Key Change Token numbers until 2025
After upgrading my prepaid meter it won’t top up

We recently supplied a new Prepaid Water Meter Keypad to a local client who returned to the Straton Prepaid Offices saying that the keypad was not working when they entered their recently purchased tokens.

Looking at their till slips it showed KRN 2 which means that he Key Change Tokens had been issued to upgrade the meter.

The client said that they had entered the Key Change Tokens and then purchased the new Black Prepaid Water Meter UIU from Straton Prepaid.

Now the water meter would not accept the new tokens.

So, I got in my car and went to the site to see for myself.

The UIU communicated and displayed the correct amount of available water as well as the correct meter number so communication between the two was good.

First step was to reset the UIU – #981# and then re-pair – #999#Serial_Number###

That didn’t work so the next step was to check that the Key Change Token numbers had been entered successfully. The only way to do so is to re-enter the issued Key Change Token numbers, which I proceeded to do.

After the first set of numbers the feedback on the UIU displayed was ‘GOOD’ with a tick. When the client said that they never saw that when they entered the numbers I knew I was on the right path.

After entering the second Key Change Token number the UIU displayed a tick.

NOTE: Not all meters will give the exact same feedback so look out for a tick, beep, series of short beeps, thumbs up, OK etc after entering each set of numbers.

After that the new prepaid water meter token numbers were entered without a problem.

Boilerplate and Editor’s Notes.
