High-security locks occupy the premium tier of residential lock hardware, offering features and protections that standard locks simply cannot match. But with prices ranging from $100 to $400 per lock (compared to $20 to $50 for standard deadbolts), the question is whether the additional security justifies the investment. Here is what makes a lock truly high-security and whether it makes sense for your home.

What Makes a Lock High-Security?
A true high-security lock meets specific standards that go far beyond what standard residential locks offer. The Underwriters Laboratories (UL) 437 standard is the benchmark for high-security lock cylinders. To earn this rating, a lock must resist picking for a minimum of 10 minutes (standard locks can be picked in seconds to minutes), resist drilling through the use of hardened steel and anti-drill pins, use patented key blanks that cannot be duplicated at standard key-cutting machines, and resist key bumping — the technique that opens most standard pin tumbler locks.
Additionally, high-security locks typically feature precision-machined components with tighter tolerances, restricted keyways that are only available through authorized dealers, key control systems that require identification to obtain duplicate keys, and additional security pins (6 or more compared to the standard 5) in complex arrangements.
Top High-Security Lock Brands
Medeco: One of the most recognized high-security brands, Medeco uses a unique rotating pin tumbler system. Their keys have angled cuts that both lift and rotate pins, making picking extremely difficult. Restricted key blanks prevent unauthorized duplication. Residential models range from $125 to $250.
Mul-T-Lock: Uses a pin-in-pin system where each pin contains a smaller internal pin, effectively doubling the number of elements that must be aligned. Known for excellent bump and pick resistance. Models range from $100 to $300.
Abloy: Uses a rotating disc system entirely different from traditional pin tumblers, making it virtually pick-proof with conventional tools. Originally from Finland, Abloy locks are considered among the most secure mechanical locks available. Models range from $150 to $400.
Schlage Primus: Adds a secondary sidebar mechanism to Schlage traditional pin tumbler design. The key must operate both the standard pins and the sidebar to open the lock. Restricted key blanks provide key control. Models range from $100 to $200.
Who Should Consider High-Security Locks?
High-security locks make the most sense for homeowners who live in higher-crime areas where burglary risk is elevated, people who need strict key control (landlords, property managers, homes with multiple key holders), those who want the absolute best mechanical security available, jewelry or valuable collection owners, and home office security for sensitive documents or equipment.
When Standard Locks Are Sufficient
For many homeowners, a quality Grade 1 or Grade 2 deadbolt provides adequate security when combined with other measures like reinforced strike plates, good lighting, and an alarm system. Remember that most residential burglaries do not involve lock picking — they involve kicking doors, breaking windows, or entering through unlocked openings. A reinforced door frame with a $50 deadbolt often provides more real-world security than a $300 lock on an unreinforced frame.
The Layered Security Approach
Security experts recommend a layered approach. Start with the basics — strong door frames, quality deadbolts, reinforced strike plates, good exterior lighting, and consistent locking habits. Add visible deterrents like cameras and alarm signage. Then, if your risk profile or peace-of-mind demands it, upgrade to high-security lock cylinders for the strongest mechanical protection available.

How often should I rekey or change my locks?
You should rekey or change locks whenever you move into a new home, after losing keys, following a break-in or attempted break-in, after ending a relationship with someone who had keys, and when keys have been in the possession of contractors or service providers. As a general practice, rekeying every few years provides added security. Rekeying is more affordable than full lock replacement and equally effective.

What is the difference between rekeying and replacing locks?
Rekeying involves changing the internal pins of an existing lock so old keys no longer work, while the lock hardware stays the same. Lock replacement involves removing the entire lock mechanism and installing new hardware. Rekeying is more affordable and ideal when your existing locks are in good condition. Full replacement is recommended when locks are worn, damaged, or you want to upgrade to higher-security models.
