Why Consider High-Security Locks?
Standard residential locks provide a basic level of security. They keep honest people out and create a legal boundary. But they can be defeated by picking, bumping, or drilling in under a minute by anyone with basic tools and a YouTube tutorial.
High-security locks from Medeco, Mul-T-Lock, and Abloy use fundamentally different internal mechanisms that resist these attacks. They also offer restricted key systems that prevent unauthorized duplication. For the Treasure Coast, where coastal properties and snowbird homes sit vacant for months, this extra protection matters.

Medeco: The American Standard
- MechanismMedeco uses pins that must be both lifted to the correct height AND rotated to the correct angle. This dual requirement defeats standard picking and bumping techniques.
- Key ControlMedeco keys use patented blanks available only through authorized Medeco dealers. No hardware store or key kiosk can copy them without authorization.
- AvailabilityMedeco has the largest dealer network in the US, making service and additional keys readily accessible on the Treasure Coast.
- Best ForResidential homes wanting maximum security with local service support. Commercial buildings with moderate key control needs.
Mul-T-Lock: The Commercial Powerhouse
Mul-T-Lock, an Israeli manufacturer now part of the ASSA ABLOY group, uses a telescoping pin design where each pin contains a smaller pin inside it. Both the inner and outer pins must align correctly for the lock to open, creating a mechanism that is extremely difficult to manipulate.
Mul-T-Lock excels in commercial applications with its flexible master key system capabilities. The Interactive+ platform offers a keyway authorization card system that gives building managers control over key duplication.

Abloy: The Finnish Engineer's Choice
Abloy uses a disc-detainer mechanism instead of pin tumblers. The key rotates a series of discs to specific positions rather than lifting pins. This design is fundamentally immune to traditional picking and bumping because there are no springs or pins to manipulate.
The Abloy Protec2 platform uses rotating disc technology combined with a patented key profile. It is widely regarded as the most secure mechanical lock available. The tradeoff is higher cost and fewer local service providers compared to Medeco.
When Standard Locks Are Not Enough
- Home sits vacant during snowbird season (months of unoccupied time)
- Previous break-in or attempted break-in through the front door lock
- Business stores high-value inventory or sensitive data
- Insurance provider recommends or requires high-security hardware
- Concern about unauthorized key copies from former tenants, employees, or contractors
- Property is in an area with higher-than-average burglary rates
Choosing the Right High-Security Lock
- For most Treasure Coast homeowners, Medeco offers the best balance of security, service availability, and price
- For commercial buildings needing flexible master key systems, Mul-T-Lock Interactive+ is excellent
- For maximum security where cost is secondary, Abloy Protec2 is the top choice
- Consider matching your lock brand to a local locksmith who is an authorized dealer for faster service
