Back in February of 2014 my wife and I changed out our original Kwikset Handle Set. We purchased our new Kwikset Handle Set with the following. Exterior: Montara #553MNH Venetian Bronze Finish (with Rounded Latch Plates and Smart Key), the Interior: Tustin #978TNL Satin Nickel Finish (LH Door). The Smart Key worked perfectly, it allowed me to key the new handleset to match all of the other keyed alike doors in the home. It looks great and operates flawlessly we really like this product.
