Lifespan TR4000I TR3000I Treadmill Magnetic Safety Key Lanyard (SK22)

## LifeSpan TR4000I TR3000I Treadmill Magnetic Safety Key Lanyard

The LifeSpan SK22 magnetic safety key lanyard is a replacement safety key for compatible LifeSpan treadmills. It is designed for the LifeSpan TR4000I and TR3000I treadmill models and replaces the original magnetic safety key when it becomes lost, damaged, or unavailable. The lanyard gives you a practical way to restore the treadmill’s safety-key setup without replacing the entire machine.

A treadmill safety key connects the user to the equipment’s emergency safety system. When the key sits in its proper position, the treadmill can operate as intended. The attached lanyard helps keep the key with the user during exercise and provides a convenient way to remove it if needed. This replacement part suits treadmill owners, fitness equipment repair technicians, gyms, and anyone maintaining a LifeSpan TR4000I or TR3000I treadmill.
