Double cylinder deadbolts are a popular choice for securing doors, especially in areas where security is a priority. Unlike single cylinder locks, they require a key on both sides, providing enhanced security but also making rekeying more complex. Understanding the right tools and procedures is essential for homeowners and locksmiths alike.
What Are Double Cylinder Deadbolts?
Double cylinder deadbolts are locks that have a key cylinder on both sides of the door. This design prevents intruders from opening the door with a credit card or other tools if they gain access to the interior side. They are commonly used in homes with glass doors or doors with windows close to the lock.
Rekeying Tools Needed
- Pinning kits with various pin sizes
- Tension wrenches
- Plug followers
- Small screwdrivers
- Key gauge or key decoder
- New key pins (if changing key configuration)
Steps to Rekey a Double Cylinder Deadbolt
Rekeying involves removing the lock cylinder, changing the pins inside to match a new key, and reassembling the lock. Here are the general steps:
Step 1: Remove the Lock Cylinder
Use a screwdriver to remove the screws holding the lock in place. Carefully extract the cylinder from the door, noting the orientation.
Step 2: Disassemble the Cylinder
Insert the plug follower into the cylinder to push out the existing pins. Use small screwdrivers to remove and replace pins as needed.
Step 3: Change the Pins
Match the new pins to the pattern of the new key. Insert the pins into the cylinder in the correct order using the pinning kit. Ensure the pins sit flush with the plug.
Step 4: Reassemble and Test
Reassemble the lock, reinstall it on the door, and test the new key to ensure it operates smoothly. Make adjustments if necessary.
Safety and Tips
Always wear safety glasses when working with small parts. Keep track of all pins and components. If unsure, consult a professional locksmith to avoid damaging the lock or compromising security.
Conclusion
Rekeying a double cylinder deadbolt requires the right tools and careful attention to detail. With practice, homeowners can perform basic rekeying, but for complex or high-security locks, professional assistance is recommended. Proper rekeying ensures your home remains secure and tailored to your needs.
