If you have an electric prepaid meter, chances are that you will be asked at one point in time to input a key change token in order to reconfigure the meter.
The Key Change token (KCT) is a group of 2 sets of numbers (usually 20 each) that are loaded into a prepaid meter when it is not accepting electricity tokens.
Most times, new electric prepaid meters will require the KCT to change the meter configuration: Tariff Index, Supply Group Code and Key Revision Number. These have to be configured rightly so the meter can accept credit tokens.
According to Ikeja Electric (IE), If you are unable to load your credit token, you may need to input the key change token directly under your purchased energy token. This, according to IE, will enable you to load your credit token.
Where you have a total of 40 digits, input the first 20 digits and press enter, input the second 20 digits and press enter, input your recharge token purchased, and press enter, then all should work well.
However, some prepaid meters may require a different approach to activation. MOJEC meter, for one was highlighted by IE. They noted that after installing the prepaid meter for the first time, an sms will be sent to your mobile phone within 72hours.
MOJEC meter has the number sequence, 45xxxxxxxxx. After you have loaded the Key Change Tokens successfully, they you can proceed to load the energy token – punch all 20 digits, then press enter.
But then, prepaid meter users have taken to the social media handles of their electricity vendors to voice their discontent with the KCT. Some agitated that despite being provided with the tokens (KCT 1 and KCT 2), and having fulfilled all righteousness, their meters still display error messages.
To understand the issue surrounding their KCT complains, the responses from the electricity vendors were perused, and some conclusions were derived.
First off, the format in which users enter their Key Change Tokens may be incorrect. They are not be entered at a go (40 in all): Input the first 20, press enter, then the next 20, press enter.
Also, the KCT may need to be newly generated. Contact your electricity vendor for this.
