TL;DR
Yes, a skilled lock picker can slowly undermine a deadbolt’s security over time by causing wear and tear. This makes the lock easier to pick in future attempts. Regular maintenance (lubrication), upgrading to high-security locks, and using reinforced strike plates are key preventative measures.
How Lock Picking Weakens Deadbolts
A deadbolt isn’t impenetrable. Repeated picking, even if unsuccessful each time, stresses the internal components. Here’s how:
- Pin Tumbler Wear: Most deadbolts use pin tumblers. Each pick attempt slightly wears these pins and their springs.
- Keyway Damage: Picks can subtly damage the keyway over time, making it easier for them to manipulate the lock’s internal mechanisms.
- Spring Fatigue: The springs that hold the pins in place lose tension with repeated use (and abuse from picking).
These effects aren’t immediately obvious but accumulate, reducing the lock’s security.
Step-by-Step Protection Guide
- Regular Lubrication: This is the simplest and most effective preventative measure.
- Use Graphite Powder: Avoid oil-based lubricants as they attract dirt.
- Application: Puff a small amount of graphite powder into the keyway every 6 months (or more frequently if the lock feels stiff).
- Inspect Your Lock Regularly: Look for signs of wear or damage.
- Stiffness: If the key is difficult to insert or turn, it’s a sign something is wrong.
- Keyway Damage: Check for scratches or marks inside the keyway.
- Upgrade to High-Security Deadbolts: These locks are designed to resist picking.
- Pick Resistance Features: Look for features like spool pins, mushroom pins, and anti-drill plates.
- Examples: Medeco, Mul-T-Lock, Assa Abloy are reputable brands.
- Reinforce the Strike Plate: The strike plate is where the bolt enters the door frame.
- Longer Screws: Replace the short screws that come with most deadbolts with 3-inch screws that reach into the wall stud. This makes it much harder to kick in the door.
- Strike Plate Material: Consider a reinforced steel strike plate.
- Consider Smart Locks (with caution): While offering convenience, smart locks aren’t immune to attacks.
- Choose Reputable Brands: Research the security features of any smart lock before purchasing.
- Keep Firmware Updated: Regularly update the lock’s firmware to patch security vulnerabilities.
- Be Aware of Your Surroundings: If you suspect someone has attempted to pick your lock, replace it immediately.
- Professional Inspection: Have a locksmith inspect the lock for damage.
Advanced Security Measures (for those concerned)
These are more complex and may require professional installation.
- Door Frame Reinforcement: Strengthen the door frame itself to resist forced entry.
- Security Film on Glass: Makes glass harder to break, delaying entry attempts.
