We tried to rekey our kwikset smart key, but
I had mine do the same thing right before I was leaving to the airport [re-keying for the house-sitter]. I was setting the lock and I hear a spring-type ping and the keying was lost.
The tumbler can be reset to your key. However, it involves disassembling
the device and has small parts.If you are feeling lucky, you can do
this yourself or take it to a qualified person.
If you are feeling lucky:
A: Disassemble the lock from the door
B: Remove the door handle from around the key side.
C: Remove the U retaining-clip from the outside of the lock that is securing it to the shaft.
D: Remove the lock from the shaft
E: Remove the U retaining-clip from the tumbler body and the case
F: You will have to press the five fingers down evenly on the length of
the case to slide the cylinder out of the case. (I cut a plastic card
with small wire cutters to make a tool, but you could probably use thick
card-stock and some scissors.)
Be careful; you will have to watch for and secure the check ball on one
side of the tumbler and the finger lock bar on the other side as you
slide this out.
G: Remove and store the check ball securely as well as the finger lock
bar. (careful with the plate surrounding the fingers that the finger
lock bar resides in)
H: Remove the finger locking plate. Carefully, make sure the fingers
are still inside and oriented correctly and the spring at the back of
the finger locking plate is left in place.
I: You will notice a u channel groove in the fingers and the finger
locking plate. Align the fingers in the finger locking plate evenly so
that the grooves in the fingers match the groove in the finger locking
J: Replace the finger locking plate with fingers aligned evenly with the
u channel groove back onto the tumbler body and hold back against the
spring left on the rear of the tumbler body. This puts the tumbler into
K: Replace the finger locking bar onto the finger locking plate while
holding the assembly against the spring and tumbler body. (If this is
done correctly, the finger locking bar will now be flush with the side
of the finger locking plate and not raised as normal.)
L: While holding the tumbler assembly together and maintaining the
locking plate pressed against the spring, Insert your new key into the
M: While holding this assembly in this position, add the check ball to the tumbler assembly.
N: While holding the assembly in position, slightly depress the black
plastic block at the back of the finger locking plate and slide this
tumbler assembly back into the tumbler case taking care to rotate the
case 90 degrees clockwise from normal. (Note the U channel groove inside
the tumbler case that normally receives the finger lock bar and use
that for orientation.)
If the tumbler does not insert cleanly, verify the finger locking bar is
flush. If it is not, redo while maintaining proper pressure to keep
the finger locking plate firmly against the spring in re-assembly.
Also, verify the fingers are not protruding from the tumbler body. If
they are, redo the procedure taking care to align the fingers properly
on assembly and maintain proper force on the finger locking plate
against the tumbler body during re-assembly and new key insertion
O: Rotate the key and tumbler body in the case to the normal position (counter-clockwise 90 degrees).
P: While holding the tumbler body firmly against the case, remove the key.
Q: Re-insert the key and verify smooth rotation.
R: Align the tumbler body and case back to the normal position and while
holding the tumbler body firmly against the case, remove the key.
S: Replace the U retaining-clip that belongs on the back of the tumbler body to secure it within the case.
T: Replace the tumbler body in the main lock shaft and secure with the shaft U retaining clip.
