Business Lock Change in DFW: When & How to Change Your Commercial Locks

When to Change Your Business Locks

Change the locks at your business in these situations:

• You move into a new commercial space — rekey or replace immediately, you don't know who has keys
• An employee with key access leaves the company — remove their access immediately
• After a break-in or security incident — replace compromised locks
• Your locks are old, worn, or outdated — upgrade to modern commercial hardware
• You want to upgrade to high-security or restricted-keyway locks — better key control
• You're implementing a master key system — change locks as part of the system design
• After a security audit reveals weaknesses — upgrade weak points

Rekey vs Replace: Which Is Right for Your Business?

For most situations, rekeying is sufficient and cheaper:

• Rekey: $25-$45 per lock cylinder — change internal pins, keep existing hardware. Best when locks are in good condition
• Replace: $100-$250 per lock — new hardware + installation. Best when locks are old, damaged, or you want to upgrade
• If you're upgrading from standard to high-security locks, replacement is necessary
• If your existing locks work fine and you just want to change the key, rekey
• We assess your existing hardware and recommend which makes sense

Types of Commercial Locks

Commercial buildings use different lock types than residential:

• Mortise locks — heavy-duty locks that fit into a pocket (mortise) cut into the door. Standard for commercial doors
• Cylindrical locks — simpler, bore-hole installation. Common on interior commercial doors
• Exit devices (panic bars) — horizontal bars on exit doors, required by fire code
• Deadbolts — commercial-grade deadbolts are heavier than residential (Grade 1 vs Grade 2)
• Electric strikes — for doors with access control systems. Allow remote unlocking
• Magnetic locks — electromagnetic locks for high-traffic or high-security doors

• Mul-T-Lock — high-security with interactive key element that prevents unauthorized copying

• Cost: $200-$500 per lock, plus restricted key blanks ($10-$25 per key)
• Essential for businesses with sensitive areas, valuable inventory, or compliance requirements

Should You Add Access Control?

If you're changing locks, consider whether it's time to upgrade to electronic access control. Keycards, fobs, or keypads eliminate the problem of lost keys and make it easy to revoke access when employees leave.

Access control also provides audit trails — you can see who entered which door and when. For businesses with compliance requirements or security concerns, this is often worth the investment. We can assess your building and recommend the right system.
