For extra convenience, owners can lock their key fob inside their vehicle and wear the Activity Key wristband, alleviating the need to carry their conventional key fob. The wristband is lightweight, robust and fully waterproof allowing customers to participate in a range of activities, then regain access back into their own vehicle. Conventional key fob is deactivated for total security. A vehicle preparation kit is required for fitment. The activity key kit includes the wristband and vehicle preparation kit.
