Quick Summary
Rekeying locks provides a cost-effective security alternative by modifying internal cylinder pins to invalidate old keys without requiring the total replacement of existing door hardware. ASAP Locksmith Vegas acts as the professional authority for these security transitions, ensuring that complex commercial master key systems and manufacturer warranties remain fully protected through expert execution. Property managers can secure their facilities immediately by calling ASAP Locksmith Vegas for a free, no-obligation estimate on commercial rekeying services or comprehensive security audits.
Rekeying Locks – Secure Your Property Fast Without Replacing Hardware
Rekeying locks is one of the fastest ways to make old keys stop working without replacing the entire lock. If you just moved in, lost a key, had a tenant move out, or want to tighten access after a break-in scare, rekeying lets you keep the existing hardware and change only the key that opens it. For many homes, that means lower cost, less disruption, and same-day security.
At ASAP Locksmith Vegas, we handle residential and commercial rekeying with the kind of care that protects both security and hardware. We work with high-security brands like Medeco and Mul-T-Lock, and we do not add extra charges for emergency rekeying on nights or weekends. That matters in Las Vegas, where too many unlicensed operators advertise a low price and then change it once they are on-site. If you need a fast, no-obligation estimate for rekeying or a security check, we can help. See also Car Lockout in Las Vegas? Get Back on the Road Without a Tow.
What Rekeying Locks Costs, Includes, and How Fast It Gets Done
What Rekeying Locks Costs, Includes, and How Fast It Gets Done in brief: Rekeying locks changes the internal pins inside a lock cylinder so old keys no longer work and new keys do. A typical three-door house rekey in Las Vegas usually costs $150 to $250, including the service call. A licensed locksmith can often finish the job in 30 to 60 minutes. Your existing hardware stays in place, which makes rekeying the lowest-cost way to secure a home compared with full lock replacement.
When you need to secure a property quickly, rekeying is usually the most practical choice. A licensed locksmith can change the internal pins in under an hour, make every old key useless, and restore control over access the same day.
Rekeying is generally far cheaper than replacing the full lock assembly. Valley Lock and Door notes that the process changes the internal pins of a lock cylinder while keeping the exterior hardware intact. If the lock is not damaged and the issue is access control, there is usually no reason to replace the whole unit.[4]
At ASAP Locksmith Vegas, we routinely secure typical local homes for $150 to $250. Because emergencies do not wait for business hours, we never add extra charges for nights or weekends, so you get immediate protection without the inflated pricing common among unlicensed operators.
What You Will Need Before the Locksmith Arrives
Before the technician arrives, count every lock that needs service, gather any working keys you still have, and make sure the doors are accessible. A little preparation helps the visit move faster, although ASAP Locksmith Vegas also performs a free on-site assessment so you do not have to figure out every detail yourself.
According to a Keytek Locksmiths survey via Rightmove, 74% of homeowners do not change their locks after moving into a new property (2025). Whether you are rekeying locks or deciding to replace locks entirely, these simple steps help you get ready:[3]
- Tally the hardware: Count every interior and exterior door cylinder.
- Locate existing keys: Even one working key can speed up the job.
- Note your brands: Check for high-security hardware like Medeco or Mul-T-Lock.
- Decide your strategy: Determine whether you want all doors keyed alike or need a master key system.
Unlicensed operators often raise prices if these details come up late. ASAP Locksmith Vegas helps prevent that bait-and-switch under Nevada State Locksmith License #NV20081079, so you do not overpay to replace front door lock hardware or change house locks when rekeying is enough.
Step 1: Decide Whether Rekeying Is the Right Move or the Wrong One
Step 1: Decide Whether Rekeying Is the Right Move or the Wrong One in brief: Rekeying is cheaper than replacing locks and works well when the hardware is in good shape but you need to revoke old key access. It is the wrong choice when locks are physically damaged, heat-worn, or missing security features such as bump resistance. If you are unsure, a licensed locksmith can inspect the hardware and recommend the right option.
Once you have your keys together, look at the hardware and choose the right security path. Rekeying locks is the best fit when your deadbolts still work properly and you simply need to revoke access from previous users. If the lock body is damaged or the mechanism is failing, replacement makes more sense.
When rekeying is the smart choice
Rekeying is usually the right call after a move, a tenant turnover, a lost key, or any situation where you want to keep the current hardware but reset access. Illinois law requires a lock to be rekeyed or replaced before a new tenant moves in, and landlords in Nevada should treat that same standard as a basic security step. If the hardware is still in good condition, rekeying is the faster and more affordable option.
A typical three-door house rekeying job usually costs $150 to $250, including the service call. That makes it a practical choice for homeowners and landlords who need to secure multiple doors without paying for full replacement on every lock.
When replacing or upgrading makes more sense
Do not rekey heat-worn cylinders or locks that are physically damaged. Las Vegas heat can wear down internal parts over time, especially on older hardware. If the lock is sticking, loose, corroded, or missing modern security features, it may be time to replace the front door lock instead of trying to keep it alive.
If you want bump resistance, better weather performance, or a fresh start with worn hardware, replacement is the better path. Smart lock conversion can also make sense if you want remote access or temporary codes, but it is not the right answer for every door.
| Feature | Rekeying | Replacing | Smart Upgrade |
|---|---|---|---|
| Best For | Lost keys, moving | Damaged hardware | Remote access |
| Average Cost | $15 to $40 | $75 to $200+ | $150 to $300+ |
| Fixes Heat Damage | ✗ | ✓ | ✓ |
| Adds Bump Resistance | ✗ | ✓ | ✓ |
Step 2: Remove the Lock Cylinder from the Door
Step 2: Remove the Lock Cylinder from the Door in brief: Yes, a locksmith can rekey a lock without the original key. The technician first picks or decodes the lock to identify the current pin setup, then moves into the standard rekeying process. This adds a few minutes, but it does not require drilling or damaging the lock.
After deciding that rekeying locks is the right choice, the technician removes the cylinder plug from the door. This is a non-destructive process that gives access to the internal pins without harming the door frame or surrounding hardware.
The exact removal method depends on the lock style. A professional usually follows these steps:
- Bypass missing keys: If you lost your key, the technician picks the lock first to turn the cylinder.
- Release knob locks: A small tool depresses the retaining clip so the knob can slide off its spindle.
- Dismantle deadbolts: The locksmith removes the interior mounting plate to expose the core.
Many homeowners assume they have to replace locks or change house locks when the keys go missing. In reality, a qualified locksmith can usually remove the cylinder without drilling. According to WifiTalents, the average cost to rekey a single lock cylinder is between $20 and $50 (2025), which is still far less than replacing the full hardware.[5]
Step 3: Swap the Pins to Match a New Key
Swapping the internal pins means removing the cylinder plug, taking out the old pins, and installing a new set that matches a fresh key. Each pin has to line up correctly. If even one is the wrong size, the key will not turn smoothly.
According to Yelp, the national average cost of rekeying locks is $140 (2025). That is one reason many homeowners choose rekeying instead of deciding to replace locks entirely. Once the cylinder is open, the locksmith follows a careful process:[1]
- Remove old pins: The plug is emptied of the existing pins.
- Match new keys: Fresh pins are selected to match the cuts on the new key blank.
- Add master pins: For master systems, master pins go between the key and driver pins.
Precision matters here. A small mistake can leave the lock sticking or unusable. If you are trying to save money by doing this yourself, it is easy to lose a spring or mix up pin sizes. For most property owners, hiring a professional is the safer path.
Step 4: Reassemble, Test, and Verify Every Lock
After the new pins are set, the locksmith reassembles the cylinder, puts it back in the door, and tests the new keys carefully. A professional also checks the old key to confirm that it no longer works, which is the whole point of rekeying.
The final testing phase should always include a few basic checks:
- Hardware alignment: The technician checks the bolt throw and strike plate engagement so the lock closes cleanly.
- Keying alike: Multiple doors can be matched to one key for easier access.
- Verification: Old keys are tested from both inside and outside to confirm they no longer work.
According to the Bureau of Justice Statistics, 34% of burglaries involve entry through the front door (2022). That is one reason proper latch alignment matters as much as the rekey itself. ASAP Locksmith Vegas provides a written warranty on every rekeying job and tests each lock before leaving the property. If you want a free, no-obligation estimate for residential lock rekeying or a commercial security audit, we can provide that before you decide whether to replace locks.
Step 5: Secure Your Key Control Going Forward
Once the hardware is tested, long-term security depends on controlling who gets a key. Good key control helps prevent unauthorized duplication and reduces the chance that you will need to rekey again sooner than expected. Keep track of copies and consider restricted keyways if access control matters.
Key control for homeowners and tenants
Limit key copies and keep a simple record of who has them. According to Security Magazine, smart locks are projected to reshape the rekeying industry by 2025 (2024), since digital codes can be changed quickly. Even so, smart locks are not the right fit for every door, and traditional hardware still works well when it is maintained properly.
If you are a tenant, ask your landlord about rekeying locks when you move in. If you are a homeowner, make sure every spare key is accounted for after a move, a contractor visit, or a service call.
Key control for landlords and commercial properties
Landlords should rekey between tenants so the next occupant starts with a clean key set. Commercial properties need the same discipline, especially when an employee leaves or access roles change. ASAP Locksmith Vegas installs restricted keyways like Medeco and Mul-T-Lock, which help prevent hardware-store duplication and give property managers tighter control over keys.
We also help businesses plan around master key systems, so access stays organized without sacrificing security. If you need transparent pricing and licensed service, we can quote the job before work begins.
How to Choose a Locksmith in Las Vegas Without Getting Scammed
To choose a locksmith in Las Vegas without getting scammed, verify a valid Nevada State Locksmith License before you book. Legitimate professionals give firm phone quotes, operate under a real business name, and carry active bonding and insurance.
Unlicensed bait-and-switch operators often quote a low fee that balloons on-site when you need to change house locks. According to the Better Business Bureau, complaints against generic locksmith operators remain common (2023). Use these checks to protect yourself:
- Check credentials: Look for state-issued credentials, like ASAP Locksmith Vegas’s Nevada State Locksmith License #NV20081079.
- Demand flat-rate pricing: Trusted technicians should not inflate prices after arriving to replace front door lock hardware.
- Confirm commercial expertise: Legitimate companies can support master key systems and high-security brands like Medeco.
