Step-by-Step Solutions

Solution 1: Double-Check Meter Number (Fixes 70% of Issues)

Problem: Token purchased for wrong meter number.

How to Verify:

  1. Look at your meter's physical label or display screen
  2. Compare with meter number on your token receipt
  3. Even one digit wrong = token won't work

Fix: If wrong, contact your vendor. Most DisCos/platforms like BuyPower offer free corrections within 24-48 hours if you haven't attempted to load the token.

Solution 2: Check for Typos (Error 06, AAAAAAA)

Problem: Entered the 20-digit token incorrectly.

Fix:

  1. Count the digits (should be exactly 20)
  2. Watch for similar-looking characters:
    • 0 (zero) vs O (letter O)
    • 1 (one) vs I (letter I) vs l (lowercase L)
    • 5 vs S
  3. Enter slowly, checking each 4-digit group

Pro Tip: If your meter supports SMS or USSD token loading, use it to avoid manual entry errors.

Solution 3: Key Change Token (KCT) Required (Error 70, Error 75, Error 12)

Problem: Your DisCo changed tariffs or a global Token Identifier (TID) rollover occurred.

What is KCT? A Key Change Token updates your meter's internal tariff data or TID. It must be loaded before credit tokens after a tariff change.

How to Get KCT:

For IKEDC (Ikeja Electric):

  1. Visit: https://www.ikejaelectric.com/kct
  2. Enter your meter number
  3. Receive KCT instantly
  4. Load KCT first, then your credit token

For AEDC (Abuja Electric):

  1. Visit: https://www.abujaelectricity.com
  2. Login or call 0803 907 0070 to request KCT

For Other DisCos:

  • Call customer care
  • Visit nearest business unit
  • Some provide KCT via SMS

Loading KCT:

  1. Enter the KCT exactly as received
  2. Press Enter
  3. Meter should display "Accepted" or "KCT Loaded"
  4. Now load your credit token

Solution 4: Meter Activation (New Meters)

Problem: Newly installed meter not accepting tokens.

Fix:

  1. Contact your DisCo with your meter number
  2. Request activation/commissioning
  3. DisCo will send an activation code
  4. Load activation code first, then credit tokens

Typical Wait Time: 24-48 hours (but can be faster if you escalate)

Solution 5: Communication Error (Error 30, E-5)

Problem: Meter and Customer Interface Unit (CIU)/keypad can't communicate.

Symptoms:

  • Keypad lights up but token not accepted
  • Display shows numbers but freezes
  • "Error 30" or "Communication Failure"

Fix:

For MOJEC Meters (Reset Procedure):

  1. On the keypad, dial: 990 then press Enter
  2. Then dial: 0000 then press Enter
  3. Then dial: 999 then press Enter
  4. Unplug the CIU from the meter
  5. Wait 30 seconds
  6. Plug back in
  7. Try token again

For Conlog/Other Meters:

  1. Dial: 755204 then press Enter (connects remote to meter)
  2. If that fails, turn off main switch to meter
  3. Wait 2 minutes
  4. Turn back on
  5. Try token

If Reset Fails:

  • Check cable between CIU and meter (may be loose)
  • Ensure meter has power supply from grid
  • Call DisCo technician (internal wiring issue)

Solution 6: Duplicate Token (ddddddd, "Token Used")

Problem: Attempting to load a token that was already accepted.

Fix:

  • Each token can only be loaded once
  • If you didn't load it before, someone else may have (check family members)
  • Contact vendor for refund if genuinely not loaded
  • Check your meter's balance — units may already be there

Solution 7: Meter Full (Unit Threshold Exceeded)

Problem: Some older meters reject tokens if total units exceed limit (e.g., 9,999 kWh).

Symptoms:

  • Token valid but meter shows "FAILED" or "Exceeds Limit"
  • Meter display shows very high existing balance

Fix:

  1. Use some of your existing units first
  2. Once balance drops below threshold, load new token
  3. If you can't consume enough units, contact DisCo to reset meter capacity

Solution 8: Token Expiry/Out of Sequence

Problem: Some tokens have validity periods or must be loaded in order.

Fix:

  • Load tokens in the order you purchased them
  • Don't "save" tokens for months (some expire in 30-90 days)
  • If expired, contact vendor for fresh token generation

Preventing Token Errors

  1. Save Receipts: Keep all token receipts (screenshot if via app)
  2. Verify Before Buying:
    • Triple-check meter number before purchase
    • Use DisCo's official platforms (BuyPower, Quickteller, bank apps)
  3. Request KCT Regularly: If you haven't loaded tokens in 6+ months, get KCT first
  4. Keep Meter Powered: Never disconnect meter from grid power completely
  5. Update Contact Info: Register phone/email with DisCo for KCT notifications

Frequently Asked Questions

Why does my prepaid meter show "Token Rejected"? The most common causes are: (1) Wrong meter number on purchase, (2) Typo when entering the 20-digit token, (3) Need for Key Change Token (KCT) due to tariff update, (4) Meter not activated (new meters), or (5) Communication error between keypad and meter (Error 30).

What is Error 30 on a prepaid meter? Error 30 means the meter cannot communicate with the Customer Interface Unit (CIU) or keypad. Fix by resetting: dial 990-Enter, 0000-Enter, 999-Enter, then unplug and replug the CIU. If this fails, check physical connections or call your DisCo.

How do I get a Key Change Token (KCT)? Visit your DisCo's website (e.g., ikejaelectric.com/kct for IKEDC) or call customer care. KCT is usually provided free and instantly. Load the KCT before loading any credit tokens after a tariff change or TID rollover.

Can I get a refund for a rejected token? Yes, if the token was genuinely not loaded. Contact your purchase platform (BuyPower, Quickteller, etc.) within 24-48 hours with your transaction reference. Provide proof the meter rejected it (photo of error screen). Most vendors process refunds within 7-14 days.

My token says "FAILED" but meter number is correct. What now? FAILED can mean: (1) Need KCT update, (2) Meter activation required (new meters), (3) Communication error (try reset), or (4) Meter fault. After trying KCT and reset, if still failing, call DisCo for technician visit.
