In this comprehensive guide, we’ll explore the ins and outs of keyed alike lock systems to help you make an informed decision.
Key Facts and Statistics on Keyed Alike Systems
- Approximately 23% of homes use keyed alike locksets on all exterior doors, allowing one master key to access the front, back, garage, etc.
- Around 18% of small businesses opt for keyed alike systems across all interior office doors, desks, cabinets, etc.
- Euro cylinder locks are the most common choice for keyed alike solutions due to their modular nature.
- Rekeying existing locks to be keyed alike costs an average of $8-15 per lock. Entirely replacing locks averages $60-100 each.
What Does “Keyed Alike” Mean?
Keyed alike refers to a master key system where two or more locks are configured to operate using the same key. This allows a single key to lock and unlock multiple doors.
It provides convenience and simplicity by consolidating all access to different doors into one universal key. Property owners only need to manage one key instead of several.
The Benefits of Keyed Alike Lock Systems
- Convenience – Only carrying and keeping track of a single master key makes access much simpler.
- Emergency Access – Keyed alike allows faster access to all emergency rooms without needing multiple keys.
- Managing Staff Access – Employers can provide one master key for all required doors without worrying about copied keys.
Can a Locksmith Set Up One Key for All Your Doors?
Feasibility and Process
Professional locksmiths can rekey your existing locks to be keyed alike. Here is how they go about it:
- Evaluate your existing locks and determine which are suitable candidates for rekeying. Euro cylinders usually work best.
- Disassemble each lock and file down the existing pin heights to a shared master key configuration.
- Reassemble the locks with the newly keyed pins, allowing your single master key to work across all doors.
Padlocks, deadbolts, and other residential or commercial locks can potentially be included in a keyed alike system.
Limitations and Security Considerations
There are some limitations though:
- Locks across different brands may not always be compatible for rekeying.
- Mixing lock types like deadbolts with euro cylinders can complicate or prevent keying alike.
- Hiring unqualified locksmiths risks compromising the system’s security.
- Losing one master key jeopardizes all access unless locks are promptly rekeyed.
How Does Keying Alike Work?
The Technical Process
When rekeying locks to be keyed alike, a locksmith follows these key steps:
- Remove the lock’s plug cylinder and inspect the keypin heights inside.
- Use pin gauges to identify the existing top and bottom pin sizes.
- File down specific pins to the same heights needed for the master key configuration.
- Insert the newly keyed pins back into the cylinder and reinstall.
- Use the master key to test and verify proper functioning.
- Repeat the process for all other locks to be included in the system.
Determining Lock Compatibility
To determine if locks can be keyed alike, you’ll need to:
- Verify the same manufacturer and model across all locks.
- Inspect the current pinning configuration of each lock.
- Consult with a certified locksmith on viable options.
Some retrofitting or new locks may be required if existing ones are incompatible.
Cost Implications
On average, you can expect to pay $8-15 per lock to have a locksmith rekey them too. Replacing locks with new matched sets can cost $60-100 each.
For a home with three exterior doors, rekeying would total around $25-45 vs. $180-300 for replacement.
Pros and Cons of Keyed Alike Locks
Advantages
- One master key provides easy access to all required doors.
- Quicker emergency access without fumbling for different keys.
- Managed staff access – employees only need one provided key.
- Potentially cost-effective by rekeying existing locks instead of full replacement.
Disadvantages
- Compromised security if the master key is stolen or duplicated.
- Rekeying all locks again is required if the master key is lost.
- Insurance policies may require separate keys for sure locks.
- Upfront costs if new keyed alike locks must be purchased.
Choosing the Right Locksmith for Keying Alike
Verifying A Locksmith’s Credentials
When hiring a locksmith, be sure to:
- Review their experience, licensing, and certifications.
- Ask about their process for keyed alike systems.
- Request client references to evaluate the quality of service.
- Get a detailed written invoice or quote before work begins.
Why Choosing an MLA-Approved Locksmith Matters
MLA or Master Locksmiths Association-approved locksmiths must meet stringent industry standards for credibility, trustworthiness, and professional service. Choosing an MLA-approved locksmith helps ensure quality workmanship and ethical business practices.
Best Practices for Implementing Keyed Alike
When planning a keyed alike system, consider the following recommendations:
- Only rekey locks within the past 10 years – older locks may need a full replacement.
- Use the same lock model across all access points for maximum compatibility.
- Upgrade to high-security key systems if managing many staff keys.
- Get master keys stamped “Do Not Duplicate” to prevent unauthorized copying.
When Does Keying Alike Make Sense?
Keying all locks to one master makes the most sense in these situations:
- Frequent access is needed through multiple exterior doors (front, back, garage entries, etc).
- Interior doors all require the same access, like bedrooms in a shared apartment.
- Businesses with many employee doors/cabinets need managed simplicity.
Keying Alike Yourself vs Hiring a Locksmith
You can rekey more straightforward locks using rekeying kits at most hardware stores. However, for more complex master key systems, specialized tools and expertise are required.
Professional locksmiths have the knowledge, equipment, experience, and efficiency to properly implement keyed alike solutions. This applies to euro cylinder locks, common in many homes and offices.
Attempting intricate rekeying without the proper skills risks damaging locks or compromising their security.
Frequently Asked Questions
Can you key alike different lock brands?
Unfortunately, most lock brands use distinct and proprietary mechanisms, making it very difficult to key locks from different manufacturers alike. Sticking to the same brand increases compatibility.
How much does it cost to have a locksmith key all doors alike?
For basic master keying of 3-5 residential door locks, expect to pay $30-75. Commercial spaces with 10+ doors can range from $100-250 depending on labour time, parts needed, etc.
What are the security risks of one master key for all locks?
Losing the master key, having it stolen or copied surreptitiously, means anyone could access all doors. This compromises security unless locks are promptly rekeyed with a new master configuration.
Can padlocks also be keyed alike door locks?
Many padlocks can be keyed alike and use the same master key. However, disc or combination padlocks usually cannot be integrated into keyed alike systems. Consult your locksmith on viable options.
How do I know if my locks can be keyed alike?
Your locksmith should inspect them in person and identify any compatibility issues or needed replacements. The same manufacturer, cylinder type, age, and condition increase the chances of rekeying success.
How Do Smart Locks for Gates Compare to Universal Access Locks for Security?
Smart locks for gates offer convenience and remote access, while universal access locks prioritize security through unique access control features. While smart locks for gates provide convenience, universal access locks provide a higher level of security to protect your property and loved ones.
Mastering Single-Key Solutions: Concluding Insights on Universal Key Creation

By understanding the ins and outs of setting up a keyed-like system, you can make the most informed choice for your residential or commercial space. A professional locksmith has the specialized skills to properly implement a master key solution tailored to your security needs and convenience.
