Quick Answer: What Does Rekeying Do?
Rekeying changes the internal pin configuration inside your existing lock cylinder.
| Before Rekeying | After Rekeying |
|---|---|
| Old keys still work | Old keys no longer work |
| Unknown copies may exist | Access is reset |
| Existing lock stays in place | Existing lock stays in place |
| Hardware does not change | New key operates the lock |
The door hardware stays where it is. The main change is simple: only the new key works.
What Is Lock Rekeying?
Rekeying reconfigures the internal pin stack inside your existing lock cylinder.
A locksmith removes the cylinder plug, replaces the key pins and driver pins with a new combination, and cuts a new key to match.
Nothing on the outside of the door changes.
Rekeying is usually a good fit when:
- the lock is still mechanically sound;
- the hardware is worth keeping;
- the key has been lost, copied, or shared;
- you want old keys to stop working;
- you want multiple locks to work with one new key.
The Real Problem Is Key History
For many Philadelphia homeowners, the lock hardware is not the problem.
The problem is key history.
You may not know:
- how many copies exist;
- who still has an old key;
- whether a contractor made a spare;
- whether a previous tenant returned every copy;
- whether a roommate, cleaner, dog walker, or guest still has access.
A “Do Not Duplicate” stamp is not the same as a restricted keyway. Many standard keys can still be copied unless the lock uses a controlled or patented system.
Rekeying resets access without automatically replacing the whole lock.
For a typical Philadelphia home with three to five exterior locks, that gap adds up fast. A Jefferson technician will assess each lock honestly on arrival and tell you which ones qualify for rekeying and which, if any, need replacement.

When Should You Rekey Your Locks
Any time a key has been outside your control, rekeying is worth considering.
Common reasons to rekey include:
- you moved into a new house or apartment
- you lost a key
- a roommate moved out
- a tenant moved out
- a contractor, cleaner, or dog walker had temporary access
- a relationship ended
- an employee left the company
- you bought a property with unknown key history
- you want all exterior doors to work with one key.
For landlords and property managers, rekeying is especially useful after tenant turnover or after regaining possession of a unit.
For Airbnb or short-term rental hosts, rekeying may make sense when keypad access is not being used or when physical keys are still part of the check-in process.
If your home was recently broken into or you discovered signs of attempted forced entry, contact us through our emergency locksmith service. That situation may call for a full security assessment before rekeying begins.
Rekeying vs. Replacing Your Locks
Rekeying and replacing solve different problems.
| Situation | Better Option |
|---|---|
| Old key should stop working | Rekeying |
| You lost a key | Rekeying |
| Tenant moved out | Rekeying |
| Lock works smoothly | Rekeying |
| Lock is damaged | Replacement or repair |
| Hardware is corroded or loose | Repair or replacement |
| You want a smart lock | Replacement or upgrade |
| You want higher-security hardware | Replacement or upgrade |
Rekeying is the right call when the lock works and access needs to be reset.
Replacement makes more sense when the lock is worn, damaged, physically compromised, or when you want to upgrade to high-security hardware or a smart lock system.
Philadelphia Homes Often Have Hardware Worth Keeping
Many older Philadelphia homes still have durable lock hardware that can continue working well when serviced correctly.
This is common in:
- Manayunk rowhomes
- Roxborough twins
- South Philadelphia rowhouses
- Germantown homes
- Chestnut Hill properties
- older apartment conversions
- Victorian-era homes with original hardware.
Pre-war rowhomes along the Manayunk hillside and older properties near Germantown Avenue often have mortise cylinders or solid brass hardware that should not be replaced automatically.
If the lock is still mechanically sound, rekeying may preserve the character and function of the door while resetting access.
When Replacement Makes More Sense
Not every lock should be rekeyed.
Replacement or repair may be the better option if:
- the cylinder is loose;
- the keyway is badly worn;
- the lock sticks even with a good key;
- the plug no longer seats properly;
- the hardware is corroded;
- the lock was damaged during a break-in attempt;
- the keyway is obsolete or incompatible;
- the lock no longer secures the door correctly.
A Jefferson technician inspects the lock first and explains whether rekeying, repair, or replacement is the better option.
Nothing proceeds without your approval.
How the Lock Rekeying Process Works
When you call (215) 798-4787, we ask a few questions so the technician arrives prepared.
We may ask:
- how many locks need service;
- whether you know the lock brand;
- whether you want all locks keyed alike;
- whether the property is residential, commercial, or rental;
- whether any keys were lost, stolen, or unreturned;
- whether the lock is sticking, loose, or damaged.
Then the process works like this:
1. On-Site Inspection
The technician inspects each lock to confirm it can be rekeyed safely.
They check:
- brand
- cylinder condition
- keyway type
- hardware condition
- door alignment
- whether the lock should be repaired or replaced instead.
2. Free On-Site Estimate
After inspection, the technician explains the work and provides a confirmed estimate.
You decide whether to proceed.
There is no obligation and no pressure.
3. Cylinder Rekeying
Once approved, the technician removes the cylinder plug and resets the internal pin configuration.
The old key should no longer operate the lock.
4. New Key Cutting
A new key is cut to match the updated cylinder.
If you want multiple exterior doors to work with one key, the technician can set compatible locks to the same key pattern.
5. Final Testing
Before leaving, the technician tests:
- the old key
- the new key
- lock operation from both sides when applicable
- door alignment
- smooth turning
- full lock engagement.
The job is not complete until the new key works correctly and the old key no longer works.
Keyed-Alike Rekeying
Keyed-alike rekeying allows multiple locks to work with one key.
This is useful for:
- front doors
- back doors
- side entrances
- basement doors
- garage entry doors
- rental units with multiple exterior locks.
Instead of carrying several similar-looking keys, you use one key for compatible locks around the property.
The technician will confirm which locks can be keyed alike during the on-site inspection.
What Types of Locks Can Be Rekeyed?
Jefferson Locksmith rekeys many common residential and commercial lock types.
These may include:
- deadbolt cylinders
- knob lock cylinders
- lever lock cylinders
- rim cylinders
- mortise cylinders
- storefront cylinders
- commercial entry cylinders
- compatible high-security
- cylinders
- master key system cylinders
- keyed smart lock cylinders when applicable.
Some locks cannot be rekeyed because of age, damage, discontinued parts, or non-standard keyways.
The technician will explain that clearly before recommending another option.
Not Every Lock Can Be Rekeyed
This matters.
A lock should not be rekeyed if the cylinder is too worn or damaged to operate reliably after the pin change.
Common reasons a lock may not qualify include:
- heavily worn pins
- a damaged cylinder plug
- internal corrosion
- obsolete keyway
- incompatible imported hardware
- missing or broken internal parts
- a lock that already fails with the current key.
Forcing a rekey on compromised hardware creates a false sense of security.
If a lock cannot be rekeyed safely, Jefferson Locksmith explains why and provides options for repair or replacement.
How Jefferson Handles Lock Rekeying Estimates
Jefferson does not publish fixed prices or provide phone estimates for lock rekeying.
An accurate estimate depends on what the technician finds on-site.
The estimate may depend on:
- number of locks
- lock brand
- cylinder type
- hardware condition
- mortise vs. standard deadbolt configuration
- whether keyed-alike service is requested
- whether new keys need to be cut
- whether any lock requires repair or replacement.
Every job starts with a free on-site inspection.
The technician examines each lock, explains the scope, and gives you a confirmed estimate before touching anything.
You decide whether to move forward.
Residential, Commercial and Landlord Lock Rekeying in Philadelphia
For homeowners, a single visit typically covers the front door, rear entrance, side door, and any secondary access points. Keyed-alike rekeying eliminates the problem of carrying multiple look-alike keys, some of which may have been duplicated over the years by previous occupants without your knowledge.
Landlords and property managers in the Manayunk and Roxborough rental corridor deal with tenant turnover on a regular cycle. Rekeying between tenants costs significantly less than replacing hardware. For a multi-unit owner with several properties turning over each year, that difference across a full portfolio represents a meaningful annual saving. Jefferson handles tenant-turnover rekeying on a scheduled basis, no need to treat it as an emergency call every time.
For commercial properties, rekeying handles office entry points, storage rooms, and access management when staff changes. If you manage multiple access levels across a building, a master key system may be worth discussing. Our commercial locksmith page covers that in detail.

Frequently Asked Questions About Lock Rekeying in Philadelphia
How much does lock rekeying cost in Philadelphia?
The cost depends on several factors: the brand and type of lock (a standard Kwikset deadbolt and a high-security Medeco cylinder involve different labor), the number of locks being rekeyed, whether the job includes keyed-alike service, and the condition of the existing hardware. Jefferson technicians inspect each lock on-site and provide a confirmed estimate before any work begins. There is no charge for the inspection and no obligation to proceed.
How long does it take to rekey a lock?
A single lock takes roughly 10 to 15 minutes. Most residential jobs covering three to five locks are complete in under an hour. A typical Manayunk or Roxborough rowhome with a front door deadbolt, rear entry, and one additional lock is usually done in 30 to 45 minutes from the time work starts.
Is rekeying as secure as installing new locks?
Yes, when the existing hardware is in good condition. The security of a lock depends on the physical strength of the cylinder and the door hardware, not on which key currently opens it. Rekeying changes only the pin configuration, the key profile that works. If the lock itself is worn, low-grade, or physically compromised, replacement is the better call. Jefferson technicians give you an honest assessment of which situation applies to each lock.
Should I rekey or replace locks when moving into a new Philadelphia home?
Rekeying is the right move in most cases. Before closing, a set of keys to your new home has typically passed through the hands of the previous owners, their family members, real estate agents, and any contractors who worked on the property. Rekeying within the first 24 to 48 hours after purchase eliminates all of that key history at a fraction of the cost of replacement. Replacement makes more sense only if the existing hardware is damaged, very low-security, or if you want to upgrade to a smart lock system.
Can all my locks be rekeyed to work with one key?
Yes. Keyed-alike rekeying sets every cylinder in your home to the same new key pattern. Front door, back door, and side entrance all operate with a single key. This eliminates a ring of look-alike keys, some of which may have been duplicated over the years by former residents. It is one of the most practical upgrades a Philadelphia homeowner can make in a single service call.
Can Philadelphia rowhome mortise locks be rekeyed?
Most can. Pre-war mortise cylinders in Manayunk, Germantown, and South Philly rowhouses are a regular part of Jefferson’s work. Technicians carry the tools and parts for older mortise hardware on every van. In cases where a cylinder is too worn or non-standard to rekey safely, the technician explains the finding, shows you what was found, and provides a cylinder replacement option with a confirmed estimate before any work proceeds.
How quickly can a Jefferson technician reach me?
Jefferson operates Monday through Sunday, 6 AM to 11 PM. Technicians dispatch from Manayunk and reach most Philadelphia addresses quickly. Callers in Roxborough, East Falls, and the northwest corridor typically see the fastest arrivals given the proximity to our Leverington Ave base. Response times vary with traffic and time of day across the broader Philadelphia area.
