Kwikset smart key has no key. need to rekey. how do I do that

If you rotate it back as much as possible toward the start position (the slot with the dot), then insert the tip of a kwikset key and give it a small twist clockwise or counter, it should be able to rotate back to start and you can remove the cylinder. I rekeyed 3 in a row no problem and had the last one jam up. I successfully restarted 3 times, but couldn't get it to complete the rekey.

Kwikset locks are inexpensive because they do not have replaceable parts. Buy a new one.

By the time the lock breaks, it's probably time to get different keys, but if you have so many keys in the hands of people you cannot contact, or you have more than three other locks keyed alike, and you must have the new lock work with the same keys as before, the place where you buy new locks probably has someone who can rekey the new lock to your old keys. Kwikset also sells locks that you can rekey to other Kwikset keys yourself. They are more expensive than other locks of the same type, but could save money long term, especially if you find a need to rekey your locks a lot (lots of visitors, part-time tenants or roommates, your kids lose their keys a lot, etc.)

if you do not have the learned key that works the lock you will need to take the lock to a locksmith that has the reset tool and they can re-learn a new key to the lock.
while at the locksmith shop - have them show you the correct way to re-learn more keys for the future -- and it is very important that you keep a working key for the lock so if the future tenants do not return keys to you, you will be able to re-key to a new key. ( you will need the special tool that fits into the little hole in the cylinder face -- get this tool from the lock shop, they should have plenty ).

Your out of luck this new design is terrible once it locks up and no keys turn it, the lock is done you will have to replace it use the traditional pin tumbler style kwikset and it can be rekeyed unlimited times by a locksmith with or without a key.

Call the 800 number for Kwikset and they will send you a replacement but only the inside lock. That's the only solution to your problem.

put the 'dummy key' that came in with it, turn it a 1/4 turn right, put smart key in, pull out smart key. pull out the key and insert the key that you would have as a desired key and turn left 1/4. thats it!!!!!!

Unfortunatley you need to have the key to remove the cylinder. You can take it to a locksmith that can pick" it to remove the cylinder and make you a key but it may be more cost effective to replace it.

Sorry not to be mre help.

Any locksmith can rekey the locks to a single Master. Some make house calls, but it costs less to take them off and take them if this is feasible.

Visit your local Home Depot and purchase a Kwikset re-keying kit. They're inexpensive and work fine but stay alert and follow the instructions properly. This kit comes complete with proper pins as well as new keys. Good Luck!
