Because you just joined the Forum today, you may not understand why folks are joking about your English...it is the traditional Forum "welcome" for new members. Many of the posts in the Forum are from people in Japan, Germany, Italy...and their English is far better than my Japanese, German, or Italian. Heck, their English is better than most folks in East Texas.

I have five or six of the "new" Kryptonite locks. They use a flat key that is very similar to that used on the OnGuard U-locks. Both the Kryptonite and OnGuard designs require that both ends of the "U" be firmly seated into the crossbar before turning the key. After both ends are fully seated, the key turns easily.

However, if either end of the "U" is NOT fully seated, the key resists turning. Because the flat keys are rather thin, someone trying to "force" the key to turn could break the key.

If the key resists turning, "rap" the round end of the "U" with your hand to seat the "U" in the crossbar. Likewise, don't let anything push on the "U" bar when you are unlocking it, such as pressure from the pole you are locked to.

I use only one lock on a daily basis, and as that lock has been locked and unlocked many times, it has loosened up and bit, and works more smoothly than it did on "Day One".

The OnGuard Brute and Kryptonite New York locks have earned the highest ratings from the UK "Sold Secure" Institute, and the ART Foundation in Holland. They are the best U-locks widely available in the USA. Their design eliminates the "slop" and "freeplay" that is common in "Brand X" U-locks, but the "price" of a tight fitting lock is that a bit of extra care is required when locking and unlocking.
