Why tpu key cover hardens in cold weather: TPU will become less flexible at low temperatures. This reduces the material’s elasticity and impact resistance, making it temporarily stiff and brittle—a reversible physical change that resolves once warmed

If the tpu key cover hardens in cold weather and gets difficult to install, please make it warmer to restore its flexibility: 1: Use a hair dryer on low or medium heat and hold it about 6–8 inches away from it. Never use high heat or hold it too close, as excessive heat can cause permanent deformation; 2: Submerge it in lukewarm water at about 40–50°C (104–122°F) for 1–2 minutes
