Using your Kryptonite U-Lock is easy. First, attach the FlexFrame - U bracket to your bike at a convenient location. Then, slide the lock into the bracket when you're not using it for easy transport. To lock your bike, place the shackle around a secure object like a bike rack and insert it into the lock body until you hear a click. When unlocking, insert one of the stainless - steel keys into the disc - style cylinder and turn it. Here are some important things to keep in mind. Don't try to force the lock open if it seems stuck; instead, check for debris in the keyhole and clean it if necessary. Avoid exposing the lock to extreme temperatures for long periods as this could affect its performance. For maintenance, regularly use the sliding dustcover to keep dirt and debris out of the lock. If the lock gets wet, dry it off with a cloth. You can also lubricate the keyhole and moving parts with a light lubricant every few months to ensure smooth operation. Remember to keep your keys in a safe place and take advantage of the Key Safe Program in case you lose them.
