Precision bump key for Weiser 5-pin cylinders. Bump keys work by transferring a sharp kinetic impact through the key to all the driver pins at once - sending them above the shear l ine for a brief moment you use to turn the cylinder. A key that doesn't match the target keyway exactly will absorb that energy wrong and give you nothing. Our WR5 bump key is precision code cut for the Weiser keyway standard, so the energy goes exactly where it needs to.
