    Does Kwikset sell a rectangular satin nickel striker plate that has outer dimensions of 2 1/4" x 1"?   Those are the dimensions of the existing hole in my doorframe and the plate that came in the Kwikset deadbolt package is too big (2 3/4" x 1 1/8").

    Installed the double sided key dead bolt but can't remove the key on the inside unless the bolt is in the unlock position. We purposely picked the double side key for safety so that children can't enter the pool area without the key.  Is this just broken?

    Asked by: Anne
    Hello Anne,It sounds like the lock was installed incorrectly. Please remove the lock and re-install the lock with the latch bolt in the locked position. If you require further assistance please contact Kwikset technical support at 1-800-327-5625.Thank you,Kwikset Support
