U.S. federal Regulation E (12 CFR Part 1005) limits your liability for unauthorized debit card transactions from a KeyBank account to $50--or the amount of unauthorized transfers before notice--if you notify KeyBank within 2 business days of learning about the loss or theft of your debit card or access device. If notification comes after 2 business days, your liability does not exceed the lesser of $500 or the sum of specified amounts. Contact KeyBank Customer Disputes at 555 Patroon Creek Blvd., NY-, as listed in their official disclosures. This applies to personal checking/debit accounts under the Electronic Fund Transfer Act (EFTA); it does not cover credit cards, merchant refunds, or business accounts.
What Controls Unauthorized Debit Card Disputes at KeyBank
The primary rule is U.S. federal EFTA, implemented as Regulation E § 1005.6, which sets consumer liability limits and requires financial institutions like KeyBank to handle error resolution for unauthorized electronic fund transfers (EFTs), including debit card transactions.
Under Reg E § 1005.6, if you notify KeyBank within 2 business days after learning of the loss or theft of your access device (such as a debit card or PIN), your liability is limited to the lesser of $50 or the amount of unauthorized transfers before notice. Notification after 2 business days increases potential liability to the lesser of $500 or the sum of unauthorized transfers before notice plus amounts from the 60 days after the first unauthorized transfer--though the $500 cap is the key confirmed limit from official text.
KeyBank, as your financial institution, must comply with these federal requirements. Their eDAS Disclosure provides the Customer Disputes mailing address but does not detail a specific debit dispute workflow beyond this.
| Liability Scenario | Maximum Liability | Notification Deadline |
|---|---|---|
| Within 2 business days of learning of loss/theft | Lesser of $50 or amount before notice | 2 business days |
| After 2 business days | Lesser of $500 or specified sum | As soon as possible |
What Does Not Control This Dispute
Unauthorized debit card disputes follow EFTA/Reg E rules for EFTs from bank accounts, not credit card billing disputes under Regulation Z or the Fair Credit Billing Act (60-day timelines). KeyBank's tools for credit card disputes, such as partnerships with Quavo and TSYS/Ethoca, apply only to credit cards and do not cover debit transactions.
This process also excludes merchant refunds, chargebacks through card networks like Visa or Mastercard (which differ for debit EFTs), wire transfers, or business account services under KeyBank's online agreements. State-specific rules may supplement federal law but do not override Reg E.
Next Steps to Dispute with KeyBank
Notify KeyBank as soon as you discover the unauthorized transaction, ideally within 2 business days of learning about any access device issue to minimize liability under Reg E § 1005.6. Write to KeyBank, Customer Disputes, 555 Patroon Creek Blvd., NY-.
Gather this evidence before contacting:
- Transaction details (date, amount, merchant if known)
- Date you learned of the unauthorized transfer
- Proof of notification (e.g., mailing receipt, call log if phone used)
- Account statements showing the debit
KeyBank must investigate per Reg E requirements. If unresolved, escalate to the Consumer Financial Protection Bureau (CFPB) or Federal Trade Commission (FTC), or your state's banking regulator or attorney general (e.g., Ohio for KeyBank headquarters).
