Lock Replacement
New lock with installation
When your lock is acting up—sticking, grinding, or not latching properly—you face a common question: should you repair it or replace it entirely? The answer depends on several factors including the lock's age, condition, security needs, and your budget. This guide helps Dallas homeowners and business owners make the right choice.
When to Repair Your Lock
Repair is Usually the Right Choice When:
- Lock is less than 10 years old
Modern locks from quality brands can last 20+ years with maintenance
- Key turns but is stiff or sticky
Often just needs cleaning, lubrication, or minor adjustment
- Deadbolt doesn't fully extend
Strike plate misalignment—easy fix with adjustment or longer screws
- You need new keys but like the lock
Rekeying costs $20-$50 vs $75-$200 for new lock
- Lock is high-quality (Grade 1 or 2)
Premium locks are worth repairing—internals are often replaceable
When to Replace Your Lock
Replacement is Better When:
- Lock is visibly damaged from a break-in
Security is compromised—repairs may not restore full protection
- Lock is old, worn, or Grade 3
Repairing a cheap lock often costs more than upgrading
- Key no longer works at all
Cylinder may be damaged beyond repair
- You want to upgrade security
Moving from Grade 3 to Grade 2 or adding smart features
- Repair cost exceeds 50% of replacement
Better investment to get a new lock with warranty
- Moving into a new home
Previous owners, contractors, and others may have keys

Example 1: Repair
Lock: Schlage B60 ($120 new)

Example 2: Replace

Repair: New cylinder + labor = $40
40/45 = 89% → Replace ✓
What About Rekeying?
Rekeying is a middle-ground option that changes your lock's internal pins so old keys won't work. It's ideal when:
Rekeying Works For:
- • Moving into a new home
- • Lost or stolen keys
- • Employee or tenant turnover
- • Matching multiple locks to one key
Cost: $20-$50 per lock
Rekeying Doesn't Help:
- • Broken or damaged locks
- • Upgrading security grade
- • Changing lock style/features
- • Very old or cheap locks
In these cases, replace
