Rekeying vs Changing Locks: Which Is Better?
Deciding whether to rekey or change your locks is a fundamental security decision for any homeowner. Both methods address different needs and offer distinct benefits. Understanding the process, cost factors, and how to verify the work will help you make the most informed choice for your property’s security.
What Affects the Cost?
Several factors influence the price of both rekeying and changing locks. For rekeying, the primary cost driver is the number of locks that need to be rekeyed. Each lock cylinder requires internal adjustments and new pins, so a house with many doors will naturally cost more. The type of lock also plays a role; some higher-security or specialized lock cylinders might have different internal mechanisms that affect labor time. For changing locks, the cost is influenced by the price of the new lock hardware itself. Standard deadbolts are less expensive than high-security models or smart locks. The number of locks being replaced, similar to rekeying, is also a significant factor. Labor is charged per lock for both services, so the more locks involved, the higher the overall expense. The complexity of the existing door hardware and the accessibility of the locks can also impact labor charges.
The Rekeying Process
Rekeying a lock essentially reprograms it to accept a new key, rendering the old keys useless. This is a cost-effective solution when you need to change access for specific individuals without replacing the entire lock mechanism. The locksmith will first disassemble the lock cylinder. They will then remove the old pins and replace them with a new set of pins that correspond to the cuts of the new key. The existing lock housing and mechanism remain in place. Once the new pins are installed, the locksmith will test the lock with the new key to ensure it operates smoothly and securely. The old keys will no longer turn the cylinder. This process is particularly useful if you’ve lost a key, had a tenant move out, or want to consolidate access to multiple locks with a single key. It’s also a common solution for managing access to rental properties or ensuring that previous residents or service personnel can no longer enter.
The Lock Changing Process
Changing locks involves removing the entire existing lock mechanism and installing a completely new one. This is a more comprehensive security upgrade. The process begins with the locksmith removing the old lock hardware, including the deadbolt, doorknob, and any associated strike plates or mounting hardware. They will then install the new lock, ensuring it is properly aligned with the door and the frame. This often includes fitting the new strike plate to ensure a secure engagement when the lock is engaged. Testing the new lock with its corresponding key is crucial to confirm smooth operation and proper security engagement. This method is recommended when the existing locks are old, worn out, malfunctioning, or if you need to upgrade to a higher level of security. It’s also the standard procedure when moving into a new home, as it guarantees that no one else has a key to your property. If you’re experiencing issues with a lock that can’t be resolved by rekeying, or if you want to install a different type of lock, such as a smart lock that may require different mounting hardware or even a key fob for access, changing the lock is the necessary step.
When to Choose Which
Choosing between rekeying and changing locks depends on your specific security needs and budget. Rekeying is generally more economical and faster than changing locks, making it ideal when the existing lock hardware is in good condition but you need to invalidate old keys. This is a good option if you’ve had a falling out with someone who had a key, or if you’re managing a property and want to change who has access without the expense of new hardware. Changing locks is the better choice for enhancing overall security, replacing worn-out or damaged locks, or when you want to install entirely new lock systems. For instance, if your current locks are easily picked or don’t offer the desired level of resistance, replacing them with high-security locks is a significant improvement. If you’ve experienced a break-in, or if you’re concerned about the age and integrity of your current locks, a full replacement provides the most robust security solution. For needing a car key replacement near me, or a general car key replacement, the process is different from residential locks but shares the principle of needing new, functioning keys and potentially new access devices like a key fob. For home security, rekeying is about the key, while changing locks is about the entire mechanism.
Judging the Finished Work
Regardless of whether you opt for rekeying or changing locks, verifying the quality of the work is important. After the locksmith has completed the job, test all the locks thoroughly. For rekeyed locks, ensure the old keys no longer operate the locks and that the new keys turn smoothly in all positions (locked, unlocked, and any intermediate positions). For changed locks, confirm that the new hardware operates correctly, that the deadbolt extends and retracts fully into the strike plate, and that the door closes and locks securely. Check that the new keys operate the locks without sticking or requiring excessive force. If you notice any stiffness, binding, or if the locks don’t engage properly, contact the provider immediately to rectify the issue. A well-executed job should result in smooth, secure operation of your locks, providing reliable access and protection for your home.
