If you’re trying to decide whether to rekey your locks or replace them entirely, you’re not alone. Most homeowners in Dallas face this question after moving into a new home, losing a key, or upgrading their security. The right choice depends on your lock condition, budget, and security needs.
Here’s what you actually need to know to make the decision.
Rekey vs Replace: The Quick Comparison
| Factor | Rekeying | Replacing |
|---|---|---|
| Cost | $20-$50 per lock | $80-$250+ per lock |
| Time Required | 15-30 minutes per lock | 30-60 minutes per lock |
| Best For | New home, lost keys, working locks | Damaged locks, outdated hardware, security upgrade |
| Security Level | Same as original lock | Can upgrade significantly |
| Hardware Changed | No — only internal pins | Yes — entire lock mechanism |
What Rekeying Actually Means
Rekeying changes the internal pins inside your existing lock so old keys won’t work anymore. The locksmith removes the lock cylinder, swaps out the pin configuration, and cuts you new keys that match. Your hardware stays the same the deadbolt, knob, and finish don’t change.
It’s the cheaper option because you’re keeping the lock body. As long as the lock itself is in decent shape, rekeying gives you fresh security without the cost of new hardware.
When to Choose Rekeying
Rekeying makes sense in these situations:
- You just bought a house. Previous owners, contractors, and real estate agents may still have keys. Rekeying ensures no one else has access.
- You lost a key. If someone could have your key, rekeying is the fastest way to eliminate the risk without replacing every lock.
- A tenant moved out. Landlords should rekey between tenants to prevent former renters from returning with old keys.
- Your locks work fine. If the deadbolt turns smoothly and the hardware is solid, there’s no reason to replace it.
- You want all locks to use one key. If you have multiple locks with different keys,residential lock services can rekey them all to match a single key.
When You Should Replace the Lock Instead
Sometimes rekeying isn’t enough. Replace your locks if:
- The lock is damaged or sticky. If the key doesn’t turn smoothly or the deadbolt jams, the internal mechanism is wearing out. Rekeying won’t fix that.
- You want better security. Basic builder-grade locks offer minimal protection. If you’re upgrading to high-security deadbolts or smart locks you need full replacement.
- The hardware is outdated. Old locks from the 1980s or 1990s don’t meet modern security standards. Replace them.
- The lock brand doesn’t support rekeying. Some cheap or off-brand locks can’t be rekeyed without costing almost as much as replacement.
- You’re changing door hardware styles. If you’re switching from brass to brushed nickel or upgrading the entire door handle set, replacement is the only option.
Cost Breakdown for Dallas Homeowners
In the Dallas-Fort Worth area, rekeying a standard deadbolt runs $20 to $50 per lock. If you’re rekeying multiple locks at once, the per-lock cost drops because the technician is already on-site.
Full lock replacement costs $80 to $250+ per lock depending on the quality of the new hardware. A basic Kwikset or Schlage deadbolt costs less than a high-security Medeco or electronic smart lock. Installation labor is included in most quotes.
If you have five locks and they all work fine, rekeying saves you $300 to $1,000 compared to replacing everything. But if your locks are fifteen years old and sticking, replacement gives you the security upgrade you need.
What Happens During a Rekey or Replacement
Rekeying Process
The locksmith removes the lock cylinder from your door, takes out the old pins, and replaces them with a new configuration that matches your new key. The whole process takes 15 to 30 minutes per lock. You get new keys on the spot.
Replacement Process
For a full lock installation the technician removes the old lock entirely knob, deadbolt, strike plate, everything. The new lock gets installed, the door is tested to make sure it latches properly, and you’re handed new keys. Takes 30 to 60 minutes per lock depending on the door condition.
Common Questions About Rekeying and Replacing Locks
Can I rekey my own locks?
Technically, yes rekey kits are sold at hardware stores. But if you’ve never done it before, you’ll likely drop pins, jam the cylinder, or cut the new key wrong. A licensed locksmith does it faster and guarantees the work.
How many times can a lock be rekeyed?
As many times as needed, as long as the lock cylinder is in good condition. Once the internal mechanism wears out, though, rekeying won’t help the lock needs replacement.
Will rekeying damage my door?
No. Rekeying only changes the lock cylinder internals. The door, frame, and hardware stay untouched.
Should I rekey or replace after a break-in?
Replace. If someone forced your lock open, the internal mechanism is likely damaged even if it still turns. A break-in is also the right time to upgrade to high-security deadbolts with reinforced strike plates.
Can all locks be rekeyed?
Most standard residential locks can be rekeyed, including Schlage, Kwikset, and Yale. Some cheaper no-name brands or specialty locks can’t be rekeyed cost-effectively. A locksmith can tell you in two seconds whether your lock is rekeyable.
