Lock Rekeying Cost Hamilton 2024: When to Rekey vs Replace Your Locks

Lock rekeying is one of the most cost-effective security upgrades available to Hamilton homeowners and businesses. Understanding when to rekey versus replace your locks can save hundreds of dollars while maintaining optimal security across Hamilton, Burlington, Oakville, Caledonia, Mississauga, Brantford, Grimsby, Guelph, Kitchener, St. Catharines and surrounding areas.

What Is Lock Rekeying?

Lock rekeying changes the internal pin configuration of your existing lock cylinder so that old keys no longer work. A locksmith creates a new key that matches the reconfigured pins, rendering all previous keys useless — without replacing the entire lock hardware.

When to Rekey Your Locks

After Moving Into a New Home: This is the single most important time to rekey. Previous owners, real estate agents, contractors, neighbors, and anyone else who had a key still have access to your home. Always rekey within the first week of moving in.

After Losing Your Keys: Lost keys mean unknown access. Rekey immediately rather than hoping keys won't be found or misused. The cost of rekeying is negligible compared to the potential security risk.

After a Break-In: Even if locks weren't damaged, rekeying ensures any copied keys are invalidated. Combine rekeying with a full security assessment for comprehensive post-incident protection.

After Employee Departure: Businesses should rekey or update access control credentials whenever employees with key access leave the organization, especially in cases of termination.

After Roommate or Tenant Changes: Landlords and property managers should rekey between tenants as a standard practice. Many Hamilton rental regulations recommend or require this.

When You Want One Key for All Locks: Keyed-alike rekeying configures all your locks to work with a single key — eliminating the frustration of carrying multiple keys.

Rekeying vs Lock Replacement: Decision Guide

• Your existing locks are in good working condition
• You want to invalidate old keys quickly and affordably
• Locks are less than 10 years old with no mechanical issues
• You want all locks keyed alike
• Budget is a primary concern

• Locks are damaged, worn, or difficult to operate
• You want to upgrade to higher security grade (Grade 3 to Grade 1)
• Current locks are outdated styles that hurt curb appeal
• You want to upgrade to smart locks or keyless entry
• Locks don't meet current insurance requirements

• Rekeying 5 locks: $200-$350
• Replacing 5 locks with Grade 2 deadbolts: $600-$1,200
• Replacing 5 locks with smart locks: $1,500-$3,000

Lock Rekeying Process

Step 1 — Assessment: The locksmith examines each lock to confirm it's suitable for rekeying. Damaged or excessively worn locks may need replacement instead.

Step 2 — Cylinder Removal: The lock cylinder is carefully removed from the door hardware without disturbing the mounting.

Step 3 — Pin Reconfiguration: Internal pins are replaced with a new combination that matches a newly cut key. This process takes 5-10 minutes per lock.

Step 4 — Testing: Each rekeyed lock is thoroughly tested with the new key to ensure smooth operation in both directions.

Step 5 — Old Key Verification: The locksmith confirms old keys no longer operate the rekeyed locks, verifying complete security.

Master Key Systems for Businesses

Master key rekeying allows businesses to create a hierarchical key system where individual employees access only their designated areas, while managers or owners carry a master key that opens all locks. This eliminates the need for large key rings while maintaining security zones.

• Basic 2-level system (master + individual): $30-$50 per lock
• 3-level system (grand master + master + individual): $50-$80 per lock
• Complex multi-level commercial systems: Custom pricing

DIY vs Professional Rekeying

While rekeying kits are available at hardware stores for $10-$25, professional rekeying is strongly recommended because locksmiths ensure proper pin sizing for smooth operation, professional tools prevent cylinder damage, warranty coverage protects against defects, and keyed-alike service requires specialized equipment.
