KeyBank has some very competitive long-term CD rates. The best rates are for the Key Tiered CD with Relationship Reward. The two best rates are a 5.25% APY 48-month CD and a 4.55% APY 23-month CD. The minimum deposit is $25,000. Without the relationship reward, the rates are 25 basis points lower.
The Relation Reward requires you to have either the Key Advantage, Key Privilege or Key Privilege Select checking accounts. The one with the smallest balance requirement is the Key Advantage which requires a combined balance of $10,000 to avoid a $15/month fee.
You can apply at a KeyBank branch or online. However, based on the online application, it appears you have to live in a state where they have branches. This includes the following states: AK, CO, ID, IN, KY, ME, MI, NY, OH, OR, UT, VT, or WA.
