High-security locks like Medeco are more secure than standard locks like Kwikset due to their advanced physical design, key control, and resistance to common forms of attack. Here’s a breakdown of why:
1. Complex Locking Mechanism
- Medeco: Uses rotating, elevating, and angled pin tumblers that must align not only vertically but also rotationally. This triple-lock requirement greatly increases pick resistance.
- Kwikset: Uses standard pin-and-tumbler design with only vertical alignment, making it much easier to pick or bump.
2. Key Control
- Medeco: Patented keyways and restricted key duplication. Keys can only be copied by authorized locksmiths with proper credentials.
- Kwikset: Keys are easily duplicated at hardware stores or kiosks with no authorization.
3. Drill & Physical Attack Resistance
- Medeco: Features hardened steel inserts to resist drilling and other physical attacks (like prying or wrenching).
- Kwikset: Minimal drill protection; vulnerable to brute-force attacks and drilling.
4. Bump Resistance
- Medeco: Specially designed pins and sidebars resist bump key attacks.
- Kwikset: Standard models are highly susceptible to bumping unless they include anti-bump features (like Kwikset SmartKey).
5. Build Quality & Tolerances
- Medeco: High manufacturing precision with tight tolerances, making unauthorized manipulation much harder.
- Kwikset: Looser tolerances reduce cost but make the locks easier to exploit with basic tools.
Summary Table:
| Feature | Medeco | Kwikset Standard |
| Lock Mechanism | Complex, rotating pins | Simple pin tumbler |
| Key Control | Restricted, patented | Easily copied |
| Drill Protection | Hardened inserts | Minimal or none |
| Bump Resistance | Very strong | Weak without SmartKey |
| Pick Resistance | High | Low |
| Manufacturing Tolerances | Tight | Loose |
Bottom Line:
Medeco locks are engineered for high-security environments (government, commercial, institutional use) where lock manipulation and unauthorized duplication pose serious risks. Kwikset locks, while affordable and widely used in residential settings, prioritize cost and convenience over advanced security.
