How to Choose the Right High-Security Brand
Consider these factors when selecting a high-security lock brand for your DFW property: Threat level — basic bump/pick resistance (Schlage Primus) vs maximum security (Medeco, Abloy). Key control needs — do you need to prevent unauthorized key duplication? Number of locks — some brands are more cost-effective at scale. Master key compatibility — if you need a master key system, ensure the brand supports multi-level mastering. Dealer availability — restricted key systems require a local authorized dealer for key duplication. MyKey is an authorized dealer for Medeco, Mul-T-Lock, and Schlage Primus in the DFW metroplex.
Choosing the Right High-Security Lock for Your DFW Property Type
High-security locks are not one-size-fits-all — the best choice depends on your specific property and threat profile. For DFW residential homes in standard neighborhoods: the Schlage B60N at Grade 1 provides excellent security at $95-150 installed and covers 95% of residential break-in attempts. Full high-security (Medeco, Mul-T-Lock) is warranted for homes with significant valuables, home office server rooms, or properties in areas with documented break-in patterns. For DFW commercial properties: high-security is the baseline recommendation for any property that handles cash, pharmaceuticals, jewelry, electronics, or sensitive data. The cost premium ($200-450 per door vs. $95-150 for Grade 1) is minor compared to the value of what's being protected. For property management: a master key system built on a high-security platform (Medeco or ASSA Abloy) provides the best combination of key control and master key functionality — property managers can't afford unauthorized key duplication across a portfolio of units. MyKey installs high-security locks across Dallas, Fort Worth, and all DFW cities and can recommend the right tier for your specific situation. Texas DPS License #B31013001.
High-Security Locks in Texas Heat: What Holds Up and What Doesn't
Not all high-security locks perform equally in DFW conditions. Medeco's hardened steel construction handles heat expansion well — the tight manufacturing tolerances don't loosen significantly in the 110°F+ temperatures that south-facing DFW doors experience. Mul-T-Lock's telescoping pin design is similarly durable in heat. ASSA Abloy's higher-end residential lines also perform well. What to avoid in Texas: high-security locks with significant rubber or polymer components in the cylinder — these can soften and degrade in extreme heat, reducing security over time. Also avoid locks with clear plastic cover plates on the keyway (aesthetic covers on some designer locks) — UV exposure causes brittleness and cracking within 2-3 years in DFW sun. When MyKey installs high-security locks in Dallas-Fort Worth, we factor in your door's sun exposure, material (steel vs. wood doors expand differently), and whether the door faces south or west (maximum sun exposure) vs. north or east. Proper hardware selection prevents the premature wear that negates the investment in high-security hardware.
Frequently Asked Questions — High-Security Locks Dallas
Q: How much does high-security lock installation cost in Dallas-Fort Worth?
A: Medeco deadbolts run $200-350 installed. Mul-T-Lock deadbolts run $180-320 installed. ASSA Abloy commercial high-security runs $250-600 per door depending on the model. These prices include the lock hardware, professional installation, and key cutting. Key duplication for high-security locks requires the authorization card and can only be done at authorized dealers — this key control feature is part of the security value.
Q: Can high-security locks be rekeyed like regular locks?
A: Yes, but only by authorized locksmiths and with the factory authorization card. The rekeying process for Medeco and Mul-T-Lock requires specialized tools and the correct replacement pins for each brand. MyKey is authorized to rekey Medeco and Mul-T-Lock cylinders in the Dallas-Fort Worth area. Rekeying a high-security lock runs $65-95 per cylinder, slightly more than standard lock rekeying due to the specialized tools required.
Q: Is a high-security lock enough, or do I need other upgrades too?
A: A high-security lock on a weak door or door frame provides limited protection. The lock is only as strong as the door frame it's mounted in. For maximum security, pair a high-security lock with a door frame reinforcement kit and a solid-core (wood) or steel door. A Medeco deadbolt in a hollow-core door with a standard strike plate is significantly less secure than a Grade 1 Schlage in a solid-core door with frame reinforcement.
Q: Do high-security locks deter burglars in DFW neighborhoods?
A: Yes, as a visible deterrent. Most residential break-ins in DFW are opportunistic — burglars avoid properties that appear harder to breach. A visibly installed Medeco or Mul-T-Lock (both have distinctive keyways that experienced burglars recognize) signals a harder target. Combined with proper exterior lighting and window security film, high-security locks contribute significantly to deterrence beyond their direct resistance to picking or drilling.
