Kryptonite U-Lock Matching Key Cover and Ring

Color code your U-Lock Keys and never mix them up again!

I use multiple Kryptonite U-Locks for my bike. It's always a hassle to lock and unlock each of them by finding the matching key for each lock. With these key covers, you can uniquely identify each key by color and match it with its U-Lock by printing both the key cover and identifying ring with the same color filament. Just slide the ring onto the opened U-Lock and press the key into the key cover.
