Medeco vs. Mul-T-Lock: Choosing a High-Security Lock

Medeco and Mul-T-Lock are two of the most trusted names in high-security locks. Both offer cylinders and deadbolts that resist picking, bumping and drilling far better than standard locks, and both offer restricted keys. So which one should you choose?

What makes a lock "high-security"

• Pick and bump resistance: extra locking elements beyond standard pins
• Drill resistance: hardened inserts protect the cylinder
• Key control: patented, restricted keys that can only be copied through an authorized dealer

How they differ

The two brands use different key and pin designs to achieve high security. In practice, the differences that matter most to customers are:

• Fit with your existing hardware. Both make cylinders that fit many mortise locks and deadbolts. Which one fits your door best can depend on the existing lock.
• Existing systems. If your building or business already uses one brand, staying with it keeps keys and service simple.
• Key feel and preference. Some people prefer one key style over the other.
• Budget. Prices vary by product line. We'll quote both if both fit.

Upgrade the cylinder, not the whole lock

You often don't need a whole new lock. Swapping the cylinder in an existing mortise lock or deadbolt for a high-security one is one of the most cost-effective security upgrades for an NYC apartment or storefront.

Our advice

Both are excellent. Bring us your door or a photo, tell us how many keys you need and whether you already use one brand, and we'll recommend the one that fits best.
