One Minute Locksmith Tips - Rekeying An Old Weiser Lock


To rekey the old weiser lock, you’ll need to get the center knob cylinder out. To accomplish this, you’ll need a W15 key cut to all nines and a rubber band.

Take the rubber band and put it through the keyring hole at the top of the W15 key. Then create a knot by running the rubber band through itself in order to secure it. Once you have that complete, take the knob and stick the key into the lock.

Rekey a Weiser Knob

Take the rubber band and wrap it around the key twice so that the pressure is on the clockwise position. Then, stretch out the rubber band and wrap it around the nearest post sticking out of the other side of the lock.

Using a rubberband to rekey a weiser lock

Flip the knob upside and down, and hold the tailpiece back. Start to gently pound the wiser lock over a hard surface, but you might want to use a mat of some kind in order to prevent scuffs and dings (either on the lock or on the hard surface).

You’re looking for either the key to spin or for the entire cylinder to pop out; either way will enable you to get the lock apart by removing the center knob cylinder. It will likely require around five taps of holding the tail piece back while tapping the wiser lock against the hard surface to get it apart.

Removing the cylinder on a weiser lock

With the center knob cylinder now removed, you can also take the rubber band off and remove the W15 key from the cylinder. At this point, you’re good to go to rekey the entire weiser lock. 

When putting the wiser lock back together, make sure to insert the new key you’ve rekeyed the lock cylinder and place the cylinder back into the wiser lock. After inserting the cylinder into place, hold back the tailpiece and turn the cylinder approximately to the five o’clock position. The cylinder should lock back in fully, and you’ll be good to go.
