My Kryptonite Lock Won't Open

Kryptonite is a maker of locking mechanisms for bicycles and vehicles such as motorcycles, scooters and snowmobiles. These locks are made for use in areas with varying amounts of crime, using hardened manganese steel for a high amount of security.

Many Kryptonite locks are secured using a four-digit combination, while others are opened with a key. If you have forgotten the combination or forgotten the key, Kryptonite may be able to help. If the lock does not open due to a defect, Kryptonite will replace the lock at no cost.

Call Kryptonite at 781-828-6655 if you have previously registered or know your lock's key number. This number is printed on the key itself. You may also contact Kryptonite if you forgot the combination, but previously registered it with the company.

Notify the customer service agent that you have lost the key or combination. If the key is lost, a new set is sent out to you in one business day. If you lost a previously registered combination, it may be given to you over the phone.

Send the lock, if you did not previously register it, and a check or money order for £13 to:

Kryptonite -- Re-key

437 Turnpike St.

Canton, MA 02021

The lock is re-keyed and mailed back to you, along with a set of two new keys.

You can also send a malfunctioning lock to this address, along with an explanation of the problem, for a free replacement lock. All Kryptonite locks are covered by a lifetime warranty.

Remove the endcap of the Bic pen by prying it off with a screwdriver, your fingernail or any other flat object. If you cannot pry it off, you may cut off the end of the pen with a pair of scissors. The endcap is the coloured part of the pen, found on the end opposite from the tip.

Remove the ink cartridge from the pen once the endcap has been pried or cut off.

Cut four perpendicular lines in the pen case where the endcap previously was. This lets the pen case expand as it enters the lock.

Slide the cut end of the pen firmly into the keyhole. Ensure that the pen goes in straight during this process.

Hold the lock steady in one hand while holding the pen with your other hand. Shake the lock around until a click sound is heard. This sound indicates that the lock is open.
