Rivian key fob for the times you dont want to bring your phone. Our engineers stress-tested the anodized aluminum loop to ensure when you clip it to your belt or backpack, it stays there until you take it off. The thermoplastic polyurethane (TPU) casing can handle tumbles onto asphalt and into mud, and the key fob is IP67-rated, which means it can be submerged in 3 feet of water for up to 30 minutes. We even did one test where we covered the key fob in soda to make sure the internal components would resist.
