AZ HB2121

Prohibits original equipment manufacturers from disabling electronic equipment (computers, smartphones, tablets, video game consoles) solely because the owner made modifications, including through remote updates or firmware changes.

Allows device owners to sue for actual damages up to $1,000 per violation plus attorney fees, with treble damages available for knowing or willful violations; also permits injunctive relief.

Establishes civil penalties of $200 for first violation, $400 for second, and $600 for third or subsequent violations, with penalties deposited into the consumer protection-consumer fraud revolving fund.

Exempts motor vehicles, motor vehicle parts, medical devices, and products not available for retail sale to consumers from the law's requirements.

Applies only to electronic equipment sold or used in Arizona at least one year after first being sold, with a three-year statute of limitations from discovery of violations.
