Rekeying a lock is the process of changing the internal pins of a lock cylinder so that a different key operates it while the old key no longer works. This process allows property owners to maintain their existing hardware while effectively resetting the security of the door. Homeowners and business managers should prioritize rekeying whenever there is a change in property possession, a loss of keys, or a need to restrict access for individuals who previously held a copy.
The decision to rekey usually stems from a desire for security and cost efficiency. It is the most direct way to ensure that only authorized people have access to a building. This guide explains the specific situations that require a lock update and how to determine if rekeying is the right choice compared to a full replacement. Expert knowledge in the field of physical security ensures that these recommendations align with best practices for maintaining a safe environment.
Moving Into a New Home
One of the most common times to rekey is immediately after purchasing a new home or moving into a new rental unit. During the construction or sale process, several people may have had access to the keys. This includes real estate agents, contractors, cleaning crews, and the previous owners. Even if the previous owner hands over a set of keys, there is no guarantee that they did not make extra copies for friends or neighbors.
A report highlighted by This Old House emphasizes that updating locks should be one of the first tasks on a moving checklist to ensure immediate privacy. Rekeying offers peace of mind by rendering any previously issued keys unusable, helping new occupants establish clear security boundaries from day one.
Lost or Stolen Keys
Losing a set of keys creates an immediate security gap. If the keys are stolen, the risk is even higher because the person who took them may know exactly which property they belong to. Even if the keys were simply misplaced, the uncertainty of whose hands they might fall into makes rekeying a necessary precaution. Understanding the essential role of locksmith services in modern security helps property owners make faster, safer decisions when access control is compromised.
Bonus Tip
If you lose your keys, check to see if your home insurance policy covers the cost of rekeying. Some policies include lock and key coverage as part of their standard protection.
Changes in Household or Staffing
Changes in living or working arrangements often necessitate a change in access. In a residential setting, this might happen after a divorce, a breakup, or when a roommate moves out. While the departing person might return their key, it is impossible to know if they made a duplicate during their stay.
In a business environment, employee turnover is a key reason for managing lock access. When an employee leaves a company, especially under difficult circumstances, rekeying office doors prevents former staff from entering the premises after hours. As noted by Bob Vila, rekeying is a widely recommended security practice for commercial properties to safeguard sensitive information and physical assets.
Comparing Rekeying and Replacing
Many people confuse rekeying with a full lock replacement. Replacing a lock involves removing the entire handle, latch, and deadbolt assembly and installing brand new hardware. Rekeying is much less invasive and focuses only on the internal cylinder.
| Feature | Rekeying | Replacing |
|---|---|---|
| Average Cost | $40 to $100 per lock | $80 to $300+ per lock |
| Hardware Used | Existing hardware stays | Entirely new hardware |
| Complexity | Low to Moderate | Moderate to High |
| Appearance | No change to the door | Changes the look of the door |
| Security Level | High (resets access) | High (adds new features) |
It is recommended to evaluate the condition of the hardware before choosing. If the current locks are high quality and in good working order, rekeying is the more logical and economical choice. However, if the locks are old, rusted, or difficult to turn, replacing the entire unit is better for long-term reliability.
Consolidation of Keys
Carrying a bulky keychain with multiple keys for different doors can be frustrating. Rekeying allows a locksmith to configure all the locks in a home to work with a single key, a process commonly known as “keying alike.” As explained by Hunker, this is possible when locks are from the same manufacturer or use the same keyway. For instance, if all exterior doors have Kwikset locks, they can be adjusted to operate with one key, simplifying daily routines and spare key management for family members.
Things to Consider Before Making a Decision
Before deciding to rekey, evaluate the following factors to ensure the best outcome for your security:
- Hardware Compatibility: Check if your locks are the same brand. Different brands often use different key shapes, which prevents them from being keyed alike.
- Lock Condition: If the lock sticks or the key is hard to turn, the internal mechanics might be worn out. Rekeying won’t fix a broken mechanism.
- Security Upgrades: If you want newer features like pick-resistance or bump-proof cylinders, a full replacement might be more effective than just rekeying.
- Smart Lock Integration: If you are interested in moving toward electronic or smart locks, you will need to replace the hardware entirely rather than rekeying the old manual locks.
- Budget: Determine how many locks need attention. Rekeying a whole house is significantly cheaper than buying new designer hardware for every door.
Common Questions About the Process
Does a locksmith need the original key to rekey a lock?
It is much easier and faster if the locksmith service has the current key. It allows them to turn the cylinder easily to remove it. If the key is missing, the locksmith must pick the lock or use other tools to gain access to the cylinder, which might increase the labor cost.
How long does it take to rekey a door?
A professional can typically rekey a single lock cylinder in about 10 to 15 minutes. A standard house with three or four exterior doors can usually be finished in under an hour.
Can I buy a kit and do it myself?
Retailers sell rekeying kits for specific brands. While this is a possibility for a handy homeowner, it requires precision. If the pins are not aligned perfectly, the lock can jam, potentially locking you out of your own home. Professional service ensures the lock functions smoothly and remains secure.
Bonus Tip
When having your locks rekeyed, ask for at least two or three extra copies of the new key immediately. It is cheaper to have them made while the locksmith is already on-site than to go to a hardware store later.

Direct Answers to Frequent Queries
Is rekeying as secure as getting new locks?
Yes. Once the internal pins are changed, the old key is completely non-functional. The lock is just as secure as a brand new one, provided the hardware itself is not damaged or compromised.
What if my locks are different brands?
If your front door is a Schlage and your back door is a Kwikset, they cannot be keyed to the same key because the physical shape of the keys is different. In this case, you would need to replace one of the locks to match the brand of the other if you want a single-key system.
Can high-security locks be rekeyed?
Most high-security locks, such as those with restricted keyways, can be rekeyed. However, these often require specialized pins and tools that only authorized dealers or professional locksmiths possess.
Should I rekey the mailbox and gate, too?
It is a good idea to rekey any lock that uses a key you might have lost or that a previous occupant had. Mailbox locks are often different types of cylinders, but can still be changed to ensure your mail remains private.
Summary of Action Steps
Deciding when to update your security depends on your specific life events. Moving into a new space, losing keys, or experiencing a change in who lives in your home are the primary triggers for rekeying. This method offers a fast and affordable way to regain control over who can enter your property without the waste of discarding perfectly good hardware.
Evaluate the physical state of your locks first. If they are sturdy and function well, rekeying is the best path forward. If they are failing or look outdated, consider a full replacement. Working with complete residential and commercial security solutions ensures proper compatibility, reliable workmanship, and long-term protection for your home.
