Quick Answer: You prevent lock picking by upgrading from low-grade cylinders to locks with security pins/sidebars, using ANSI Grade 1 hardware on exterior doors, and reinforcing the door/frame so attackers can’t switch to brute force. Cheap knob locks and builder-grade deadbolts are the most common weak links. In Sugar Land, we see a pattern: homeowners upgrade one visible lock (usually the front door) but keep weaker hardware on the garage-entry or back door. That’s where opportunistic entry a
| Lock/cylinder type | Picking resistance | Why |
|---|---|---|
| Grade 3 builder deadbolt | Low | Basic pins, looser tolerances |
| Standard knob lock | Low | Often minimal security features |
| Grade 2 deadbolt with security pins | Medium | Spool/serrated pins increase difficulty |
| Grade 1 / high-security cylinder | High | Sidebars, restricted keyways, hardened parts |
1. Install ANSI Grade 1 deadbolts on exterior doors
2. Choose cylinders with spool/serrated pins or true high-security designs
3. Reinforce the strike plate and frame (picking isn’t the only threat)
4. Don’t rely on knob locks as your primary security
5. Keep secondary entry points (garage entry, side door) at the same security level
If you’ve had multiple people with keys over the years (contractors, former roommates, tenants), picking may not be the real issue—uncontrolled key copies can be.
In that case, a rekey or restricted key system can be the more meaningful upgrade.
