3. Operating Instructions (Rekeying Process)
These keys are used to rekey a Kwikset 5-pin lock cylinder to match the bitting of the provided KW1 key. The rekeying process involves disassembling the lock cylinder and replacing the existing pins with new pins that correspond to the cuts on the new KW1 key.
3.1 General Rekeying Steps (Consult Kwikset Rekeying Kit Instructions for detailed steps):
- Remove the Cylinder: Disassemble the lockset from the door and remove the cylinder plug.
- Insert New Key: Insert one of the new Kwikset KW1 keys into the cylinder plug.
- Remove Old Pins: Using a follower bar, carefully push out the old pins and springs from the cylinder.
- Install New Pins: Refer to the Kwikset rekeying kit for the correct pin sizes. Install new bottom pins into the cylinder plug, aligning them with the cuts of the new KW1 key.
- Install Top Pins and Springs: Place the new top pins and springs into the cylinder housing.
- Reassemble: Carefully reassemble the cylinder plug into the housing, ensuring all pins and springs are correctly seated.
- Test: Test the rekeyed lock with the new KW1 key to ensure smooth operation.
Important: Each pair of KW1 keys provided is unique. Use one key from a pair to rekey a lock, and the other as a spare or for another lock you wish to match to the same bitting.
4. Maintenance
To ensure the longevity and proper function of your Kwikset KW1 keys and the locks they operate:
- Keep Clean: Periodically wipe keys with a soft, dry cloth to remove dirt or debris.
- Avoid Damage: Do not bend, scratch, or modify the keys, as this can impair their function or damage the lock cylinder.
- Proper Storage: Store keys in a dry place, away from extreme temperatures or corrosive materials.
- Lock Lubrication: For optimal lock performance, periodically lubricate the lock cylinder with a graphite-based lubricant, not oil-based sprays.
5. Troubleshooting
If you encounter issues after rekeying a lock with a KW1 key:
- Key Does Not Insert Fully: Check for obstructions in the keyway. Ensure the key is not bent or damaged.
- Key Inserts but Does Not Turn: This often indicates incorrect pin alignment during rekeying. Carefully re-examine the cylinder and pin placement according to the rekeying kit instructions. Ensure the correct pins were used for the KW1 key bitting.
- Key Is Stiff or Hard to Turn: The lock cylinder may require lubrication. Apply a small amount of graphite lubricant into the keyway. If the issue persists, check for debris or misalignment within the cylinder.
- Lock Malfunctions After Rekeying: If the lock does not function correctly, it is advisable to disassemble and reassemble the cylinder, paying close attention to pin placement and spring tension. If problems persist, consult a professional locksmith.
