Quick answer: high-security locks like Medeco and Mul-T-Lock resist picking, drilling, and key copying far better than regular locks, and cost about $150 to $400 per lock installed. This guide covers the brands, key control, cost, and whether high-security locks are worth it in Indianapolis.
If you want more than basic security on your front door or facility, high-security locks are the upgrade. Below is how they work and what they cost.
What Is a High-Security Lock?
A high-security lock is built to resist physical attack and unauthorized key copying. High-security locks use hardened parts, complex cylinders, and patented keys for real protection.
Unlike regular locks, high-security locks meet strict independent standards like UL 437 or ANSI/BHMA grades. UL 437 evaluates locks against picking, drilling, and destructive entry, and ANSI/BHMA A156.30 sets security-performance requirements for high-security cylinders.
High security locks come as deadbolts, cylinders, and padlocks, so you can protect a door, a gate, or a storeroom. Because high security locks combine drill resistance, pick resistance, and key control, they raise the security on every entry point and keep your keys under your control.
High-Security Locks vs Regular Locks
The difference is in the materials, the cylinder, and the keys. Regular locks are designed for basic privacy and everyday deterrence, while high-security locks stop a determined attacker.
- Regular locks use softer brass or aluminum alloys that break under heavy force
- Regular locks use a single linear row of pin tumblers that can be manipulated
- Regular locks let anyone with the key copy it at a hardware store
- High-security locks add hardened steel, drill resistance, and pick resistance
- High-security locks control who can cut a key
Key Control and Restricted Keys
Key control is the feature that sets high-security locks apart. Patented key control means only an authorized dealer can cut a key for your lock, so no one copies your keys behind your back.
For a business, that means a former employee cannot duplicate a key at a kiosk. For a home, it means your keys stay under your control.
Top High-Security Lock Brands
A few brands lead the high-security locks market. A locksmith can fit any of them to your door.
Medeco
Medeco is a top name in high-security locks, known for pick and drill resistance and strong key control. Medeco cylinders meet ANSI grades and fit standard deadbolts, so a Medeco upgrade is easy.
Mul-T-Lock
Mul-T-Lock is another leader, popular for its telescoping pin design. The Mul-T-Lock MT5+ features a locking bar mechanism and patented key control for high security applications.
Other High-Security Brands
Abloy, Abus, and Schlage Primus also make strong high-security locks and padlocks. A locksmith helps you match the right cylinder to your door and budget.
Where High-Security Locks Are Used
High-security locks are essential for protecting government and military installations, and they are common on hospitals, data centers, and any facility that needs tight key control. At home, they suit a front door, a gun room, or a home office.
High-Security Lock Cost in Indianapolis
High-security locks are significantly more expensive than regular locks, because of the materials and the patented keys. Expect about $150 to $400 per lock installed, and $20 to $60 for each extra restricted key.
Are High-Security Locks Worth It?
For most homes, a high-security deadbolt on the front door is worth it if you want strong protection and key control. For a business, high-security locks are almost always worth the cost.
If your only worry is a lost key, a simple rekey may be enough. If you want to stop drilling, picking, and copied keys, high-security locks are the answer.
