Warranty Basics That Apply to Any Brand

The general rules behind every manufacturer warranty — your rights, what proves coverage, and where registration actually matters.

• Manufacturer warranty and an extended/retailer 'protection plan' are two different things — the manufacturer warranty is free and covers defects; an extended plan (Geek Squad, Asurion, SquareTrade) is a separate paid service contract sold by a third party, not the maker.
• The Magnuson-Moss Warranty Act and the implied warranty of merchantability protect you beyond the written terms — this federal law preserves an implied warranty that goods work as expected, and a written warranty can't disclaim it while it lasts — baseline protection even after fine-print limits.
• Keep the receipt / proof of purchase — it's what actually proves coverage — almost every brand requires a dated proof of purchase to validate a claim and set the start date; without it a valid claim can be denied.
• Many credit cards add extended-warranty coverage automatically when you pay with the card — Visa, Mastercard and Amex have historically extended the maker's warranty (often by up to a year) at no cost on eligible purchases — check your card's current benefits guide.
• In the US you usually do NOT have to register a product to be covered — registration mainly enables recalls and marketing; some brands (Instant Pot) state in writing that not registering won't reduce your rights. Exceptions exist where registration unlocks an extension (LG, SharkNinja, Bosch lasers).
• 'Warranty void if removed/tampered' stickers are often unenforceable — the FTC has warned that tie-in rules and warranty-void stickers generally violate the Magnuson-Moss Act, so opening a device or using third-party parts usually can't void coverage unless it caused the damage.
• Find the serial number before you start a claim — warranty status is keyed to the serial/model number (Apple, HP, Dell, Lenovo lookups); it's on a device sticker, under the battery, in Settings/About, or on the original box and receipt.
• Whether an extended warranty is 'worth it' depends on price, failure odds and overlap — it makes sense when the plan is cheap relative to the item, the product is failure-prone or costly to repair, and it adds real coverage (e.g. accidental damage) you don't already get from the maker or your credit card.

Never lose a warranty again

These rules only help if you can prove when you bought the product. WarrantyKeep stores each product's purchase date, receipt photo and warranty length, and reminds you before it expires.
