How to Rekey a Kwikset Lock: A Step-by-Step Guide
Rekeying a Kwikset lock is a cost-effective and straightforward way to enhance your home security without replacing the entire lock. Whether you’ve just moved into a new house, lost your keys, or simply want to control who has access to your property, rekeying is a practical solution. This comprehensive guide will walk you through the process of rekeying a Kwikset lock, providing detailed instructions and helpful tips to ensure a successful outcome.
## Why Rekey Your Kwikset Lock?
Before we dive into the how-to, let’s understand why rekeying is a smart choice:
* **Security Enhancement:** Rekeying renders old keys useless, preventing unauthorized access to your home. This is particularly important when you move into a new house, as you don’t know who might have copies of the old keys.
* **Cost-Effectiveness:** Rekeying is significantly cheaper than replacing the entire lock. You only need to change the internal components of the lock cylinder, saving you money on hardware and installation costs.
* **Convenience:** Rekeying allows you to use a single key for multiple locks. If you have several Kwikset locks in your home, you can rekey them to work with the same key, simplifying your key management.
* **Peace of Mind:** Knowing that only you and trusted individuals have access to your home provides peace of mind and enhances your overall sense of security.
## Tools and Materials You’ll Need
Before you start, gather the necessary tools and materials:
* **Kwikset Rekeying Kit:** This kit typically includes a new set of keys, a rekeying tool (also known as a SmartKey tool or Learn Tool), and replacement pins (optional, but recommended).
* **Screwdriver:** You’ll need a Phillips head screwdriver to remove the lock from the door and disassemble the cylinder.
* **Tweezers or Small Pliers:** These tools will help you handle the small pins inside the lock cylinder.
* **Original Key:** You’ll need the original key that currently operates the lock.
* **New Key:** You’ll need the new key that you want to use to operate the lock after rekeying.
* **Work Surface:** A clean, well-lit work surface is essential for organizing the small parts and preventing loss.
* **Optional: Lubricant:** A small amount of lubricant, such as WD-40 or silicone spray, can help smooth the operation of the lock cylinder.
## Step-by-Step Guide to Rekeying a Kwikset Lock
Follow these detailed steps to rekey your Kwikset lock successfully:
### Step 1: Remove the Lock from the Door
1. **Loosen the Screws:** Use a Phillips head screwdriver to loosen the screws that secure the interior portion of the lock to the door.
2. **Remove the Interior Portion:** Carefully detach the interior portion of the lock from the door. This will expose the mounting plate and the through-bolts.
3. **Remove the Exterior Portion:** Unscrew the through-bolts that hold the exterior portion of the lock in place. Gently pull the exterior portion of the lock away from the door.
4. **Separate the Cylinder:** Depending on the Kwikset model, the cylinder may be held in place by a small screw or clip. Locate the screw or clip and remove it to release the cylinder. In some cases, you may need to use a small screwdriver or pick to gently pry the cylinder out.
### Step 2: Identify Your Lock Type
Kwikset primarily uses two rekeying technologies: SmartKey and traditional pin-and-tumbler. The rekeying process differs slightly depending on the lock type. Most newer Kwikset locks use SmartKey technology. If your lock has a small slot or hole near the keyway, it’s likely a SmartKey lock. If you see pins inside the cylinder when you remove the key, it is a standard pin and tumbler lock. We will discuss both.
### Step 3A: Rekeying a Kwikset SmartKey Lock
1. **Insert the Original Key:** Insert the original key that currently operates the lock into the keyway.
2. **Insert the SmartKey Tool:** Locate the small slot or hole near the keyway. Insert the SmartKey tool (or Learn Tool) into this slot. Push the tool in firmly until you feel a click or resistance. This disengages the side locking bars.
3. **Remove the Original Key:** While keeping the SmartKey tool inserted, remove the original key from the keyway.
4. **Insert the New Key:** Insert the new key that you want to use to operate the lock into the keyway. Make sure the key is fully inserted.
5. **Remove the SmartKey Tool:** Remove the SmartKey tool from the slot. The side locking bars will now engage with the new key.
6. **Test the New Key:** Remove the new key and re-insert it to ensure it turns smoothly and operates the lock cylinder correctly. If the key does not turn smoothly, repeat steps 2-5.
### Step 3B: Rekeying a Traditional Pin-and-Tumbler Kwikset Lock
This process is more involved and requires careful handling of small parts. It is recommended to have a well-lit and organized workspace.
1. **Remove the Cylinder Plug Retaining Clip (if applicable):** Some Kwikset cylinders have a retaining clip that holds the cylinder plug in place. If present, carefully remove this clip using a small screwdriver or pick.
2. **Insert the Original Key:** Insert the original key fully into the cylinder. This aligns the pin stacks and allows you to remove the cylinder plug.
3. **Remove the Cylinder Plug:** With the original key inserted, gently push the cylinder plug (the part that the key goes into) out of the cylinder housing. Be extremely careful, as the pin stacks and springs are under pressure and will fly out if you’re not cautious. It’s best to do this over a clean, contained surface.
4. **Remove the Old Pins and Springs:** With the cylinder plug removed, carefully remove the old pins and springs from each of the pin chambers. There are typically two types of pins: key pins (the ones that touch the key) and driver pins (the ones above the key pins). Keep each set of pins organized by chamber. A pin tray or a piece of paper with numbered sections can be very helpful.
5. **Insert the New Key:** Insert the new key into the cylinder plug.
6. **Insert the New Pins and Springs:** Now, you need to match the correct pin heights to the new key. Look at the cuts on the new key. Each cut corresponds to a specific pin height. Insert the correct key pin into each chamber, so that the top of the pin is flush with the cylinder plug surface when the new key is inserted. Then, place the driver pin and spring on top of the key pin in each chamber.
7. **Reassemble the Cylinder Plug:** Carefully insert the cylinder plug back into the cylinder housing, making sure all the pins and springs stay in place. Use the original key to help align everything as you slide the plug back in. You might need to use a small tool to compress the springs as you reinsert the plug.
8. **Replace the Cylinder Plug Retaining Clip (if applicable):** If your cylinder had a retaining clip, reinstall it to secure the cylinder plug.
9. **Test the New Key:** Insert the new key and turn it to ensure the cylinder operates smoothly. If it doesn’t, you may need to remove the cylinder plug again and check the pin alignment. Ensure each pin is the correct height and that the springs are properly seated.
### Step 4: Reinstall the Lock
1. **Reinsert the Cylinder:** Carefully reinsert the cylinder into the lock housing. Ensure it is properly aligned and secured with the screw or clip that you removed earlier.
2. **Reattach the Exterior Portion:** Align the exterior portion of the lock with the door and reinsert the through-bolts. Tighten the bolts securely.
3. **Reattach the Interior Portion:** Reattach the interior portion of the lock to the door, aligning it with the mounting plate. Tighten the screws securely.
4. **Test the Lock:** Test the lock thoroughly with the new key to ensure it operates smoothly and securely. Open and close the door several times to verify the lock functions correctly.
## Troubleshooting Tips
* **Key Doesn’t Turn:** If the key doesn’t turn after rekeying, double-check that you inserted the SmartKey tool or Learn Tool correctly and followed the instructions precisely. For pin-and-tumbler locks, ensure that all the pins are correctly aligned and that the springs are properly seated. Also, check that the new key is fully inserted.
* **Lock is Stiff:** If the lock feels stiff after rekeying, apply a small amount of lubricant, such as WD-40 or silicone spray, to the keyway. Insert the key and turn it several times to distribute the lubricant.
* **Pins Fall Out:** When rekeying a traditional pin-and-tumbler lock, it’s common for pins and springs to fall out. Work in a clean, well-lit area and use tweezers or small pliers to handle the small parts. Keep the pins organized by chamber to ensure you reassemble them correctly.
* **SmartKey Tool Won’t Insert:** If the SmartKey tool won’t insert into the slot, ensure that the original key is fully inserted into the keyway. The tool will only engage when the key is properly positioned.
* **Difficulty Removing Cylinder Plug:** If you have difficulty removing the cylinder plug on a traditional lock, ensure the key is fully inserted and apply gentle but firm pressure. Avoid excessive force, as this could damage the cylinder. Use a lubricant if necessary.
## Important Considerations
* **Kwikset Lock Types:** Kwikset offers various types of locks, including deadbolts, doorknobs, and levers. The rekeying process is generally similar for all Kwikset locks, but there may be slight variations depending on the model. Refer to the specific instructions for your lock model if available.
* **Key Control:** After rekeying, keep your new keys in a safe and secure location. Avoid leaving keys in obvious places, such as under doormats or in flowerpots. Consider using a key cabinet or lockbox to store spare keys.
* **Professional Assistance:** If you’re uncomfortable rekeying your Kwikset lock yourself, or if you encounter any difficulties, consider hiring a professional locksmith. A locksmith has the expertise and tools to rekey locks quickly and efficiently.
* **Rekeying Frequency:** It’s generally recommended to rekey your locks every few years, or whenever you experience a change in circumstances, such as moving into a new house, losing your keys, or experiencing a security breach.
* **SmartKey Security:** Kwikset SmartKey technology is designed to be highly secure and resistant to picking and bumping. However, it’s still important to take precautions to protect your keys and prevent unauthorized access to your home.
## Maintaining Your Rekeyed Lock
After rekeying your Kwikset lock, proper maintenance will help ensure its longevity and smooth operation:
* **Lubricate Regularly:** Apply a small amount of lubricant to the keyway every few months to keep the internal mechanisms moving freely. Avoid using graphite-based lubricants, as they can attract dirt and debris.
* **Clean the Keyway:** Periodically clean the keyway with a soft brush or compressed air to remove any dirt or debris that may have accumulated.
* **Inspect for Damage:** Regularly inspect the lock for any signs of damage, such as cracks, loose screws, or corrosion. Address any issues promptly to prevent further damage.
* **Protect from the Elements:** If your lock is exposed to harsh weather conditions, consider using a lock cover to protect it from rain, snow, and sun.
## When to Replace Instead of Rekey
While rekeying is a great option in many scenarios, sometimes replacement is the better choice. Consider replacing your Kwikset lock if:
* **The Lock is Damaged:** If the lock is physically damaged, such as having a broken cylinder, bent bolts, or a cracked housing, replacement is necessary.
* **The Lock is Old and Worn:** Over time, locks can wear out due to age and usage. If your lock is old and worn, it may be more cost-effective to replace it than to repair it.
* **You Want to Upgrade Security:** If you want to upgrade to a higher level of security, such as a smart lock or a high-security deadbolt, replacement is the best option.
* **A Break-In Has Occurred:** After a break-in, it’s a good idea to replace your locks, even if they don’t appear to be damaged. This will provide you with added peace of mind.
