    Asked by: RudedogEOD
    Hi RudedogEOD,Kwikset model 665 SMT has SmartKey technology, which provides you the flexibility to re-key your own locks quickly and easily without removing them from your door.

    I installed the double cylinder dealdbolt as a replacement for the exact model. From the inside, the keys turn the cylinder just fine. When using the keys from the outside, the keys hangs and the cylinder will not turn. Any ideas …….. a bad cylinder? 

    Asked by: Bcubed
    Hi Bcubed,Please follow these trouble shooting steps to reset your cylinder. (1) Insert the last key that you tried to program to the unit. (2) Pull the key out a notch at a time and try to turn it at the same time to the quarter turn position to the right. (3) If the key turns to the quart turn position, insert your smart key tool and then remove your key. (4) Remove the key and insert the key that came with the box and turn it back to veritcal at 12 o'clock. (5) Then re-do the re-keying steps that came with the box. For further assistance please contact Kwikset support at: 1-800-327-5625.Thank you,Kwikset
