To remove a deadbolt security screw, the method depends heavily on the type of security screw used. Standard screws can be removed with a regular screwdriver, while security screws are designed to resist removal and may require special tools or techniques.
Not all screws used in a deadbolt are "security" screws in the sense that they are hard to remove. Many deadbolts use standard Phillips or flathead screws. However, some may incorporate specific security screws designed to prevent tampering or unauthorized removal. Common types of difficult-to-remove security screws include:
- One-Way Screws: Designed to turn only in one direction (tightening).
- Tamper-Resistant Screws: Require special bits (like security Torx with a pin) to turn.
- Screws with Unique Heads: Designs that don't match standard screwdriver types.
Methods for Removing Deadbolt Security Screws
The approach you take depends on the type of screw you encounter.
Removing Standard Screws
For standard Phillips or flathead screws, simply use the appropriately sized screwdriver and turn counter-clockwise. Ensure the screwdriver tip fits snugly to avoid stripping the head.
Removing Tamper-Resistant Screws
If the screw has a head with a pin in the center (like a security Torx) or an unusual shape requiring a specific tool, you will need a matching security bit set. Insert the correct bit into a screwdriver handle or drill and unscrew.
Removing Difficult or One-Way Screws
One-way screws or those with stripped/damaged heads can be challenging. Here are a few methods:
- Using Pliers or Vice Grips: If the screw head protrudes even slightly, you can grip it. As demonstrated in one guide on removing one-way screws, you can take your like pliers [or] vice grip vice grip. After you've tapped it out slightly, you can grasp it and turn it. This method uses the strong grip of the pliers/vice grips to provide the torque needed to turn the screw out.
- Screw Extractor Kit: This is a common method for stripped or one-way screws.
- Use a drill bit (usually included in the kit) to drill a pilot hole into the center of the screw head.
- Insert the extractor tool (which has a reverse thread) into the hole.
- Slowly turn the extractor counter-clockwise. It will bite into the screw and thread it out.
- Cutting a Slot: If the screw head is flush or slightly recessed, you can use a rotary tool with a thin cutoff wheel to carefully cut a straight slot across the screw head. Once a slot is created, you can often use a flathead screwdriver to turn it out. Exercise caution and wear eye protection when using power tools.
- Drilling Out the Screw Head: As a last resort, you can drill out the entire screw head. Use a drill bit slightly larger than the screw shank. This will remove the head, allowing you to remove the deadbolt component. You will then need to remove the remaining screw shank from the door frame or door jamb using pliers.
Important Tips & Safety
- Always wear safety glasses when using tools, especially power tools.
- Use the correct size and type of tool for the screw to avoid further damage.
- Apply firm, steady pressure when turning to maintain grip.
- If a screw is stuck, sometimes applying a penetrating lubricant can help (though less common for door hardware).
Removing a deadbolt security screw ranges from a simple turn of a screwdriver to requiring specialized tools and techniques depending on the type of screw you are dealing with.
