The reason you are seeing a difference in treatment between the two items is because the administrative system handles the verification workflows for the stylus and the keyboard completely differently backend-wise.
When you contacted support four months ago for the Pencil Pro, the agent likely generated a manual registration modification token to link the accessory coverage window. However, this step is completely unnecessary for your new keyboard due to the following billing policies:
- No Manual Linking Panel for Keyboards: Unlike the stylus, which sometimes requires a manual system push to match purchase windows, the Magic Keyboard does not have a dedicated entry path inside the support console to be paired ahead of time. The support agent physically cannot input the keyboard's serial number into your active tablet contract.
- Coverage is Validated at the Time of Claim: Do not worry that the keyboard does not explicitly show up on your coverage profile screen right now. If the keyboard ever sustains accidental damage, the service technicians will simply check the serial number to confirm it is a genuine accessory, verify it matches your tablet model, and process the replacement under the standard dynamic service fee.
- Keep Your Retail Purchase Receipts: Since you bought all three devices on entirely different dates, the most important step is to safely archive your retail invoices and purchase receipts. If you ever need to file a hardware claim for the keyboard, having the purchase receipt handy will instantly prove that the accessory belongs to you and is within its valid coverage lifespan.
