How Lock Rekeying Works in San Diego
Lock rekeying is a precise technical process that alters the internal configuration of your lock so that a new, unique key is required to operate it. Understanding how it works helps explain why rekeying is both effective and economical. When you call Locksmith Magic at (619) 416-2467, we dispatch a licensed technician to your San Diego location equipped with professional rekeying tools and a complete pin kit covering all major lock brands.
The process begins with our technician removing the lock cylinder from the lock body. In most residential locks, this involves removing the lock from the door, extracting the cylinder plug, and accessing the pin chambers inside. Each pin chamber contains a spring-loaded driver pin and a key pin. The key pins are what make each key unique. Their varying heights correspond to the specific cuts on your key. When the correct key is inserted, all pin breaks align at the shear line, allowing the cylinder to rotate and the lock to open.
During rekeying, our locksmith removes the existing key pins and replaces them with new pins of different heights that match a brand-new key. The springs and driver pins are inspected and reused if they are in good condition, or replaced if worn. Once the new pins are set, the cylinder is reassembled, reinstalled in the lock body, and the lock is mounted back on the door. Your technician then tests the new key multiple times to ensure smooth, reliable operation in both the lock and unlock directions.
The entire rekeying process takes approximately 10 to 15 minutes per lock for an experienced locksmith. If you are having multiple locks rekeyed, especially if you want them keyed alike, the process is even more efficient because the same pin configuration is repeated across all locks. We commonly rekey four to eight locks in a single visit for homeowners in neighborhoods like Point Loma, Ocean Beach, and Tierrasanta who want comprehensive security updates without replacing perfectly functional hardware.
For commercial properties, rekeying can involve more complex systems including master key hierarchies and restricted keyway cylinders. Our technicians are trained in commercial rekeying for brands like Corbin Russwin, Sargent, and Best Access Systems. Whether your business is in the Gaslamp Quarter or an industrial park in Kearny Mesa, we deliver precise commercial rekeying that integrates seamlessly with your existing security infrastructure.

Rekey vs. Lock Change: Which Is Right for Your San Diego Home?
One of the most common questions we hear from San Diego homeowners is whether they should rekey their locks or replace them entirely. Both options restore your security, but they differ significantly in cost, scope, and outcome. At Locksmith Magic, we always provide honest advice based on your specific situation rather than pushing the more expensive option.
Choose rekeying when: Your existing locks are in good physical condition, function smoothly, and you are satisfied with their appearance and security grade. Rekeying is ideal after moving into a previously owned home, losing a key, or ending a relationship where your partner had a copy. It is also the right choice when you want all your locks to work with one key (keyed alike) without buying new hardware. Rekeying typically saves you 40 to 60 percent compared to a full lock change, making it the budget-friendly security reset that most homeowners in San Diego need.
Choose a full lock change when: Your existing hardware is physically damaged, visibly worn, rusted, or outdated. If your locks are more than 8 to 10 years old, they may lack modern security features like anti-bump pins, reinforced strike plates, and pick-resistant keyways. A lock change is also the right move if you want to upgrade your security level, for instance, switching from a basic Kwikset to a high-security Medeco deadbolt. After a break-in where the lock was damaged or compromised, replacement is almost always necessary.
There are also situations where a combination approach makes the most sense. For example, you might replace your front door deadbolt with a new high-security model while rekeying the back door and side door locks that are still in excellent shape. This hybrid approach is common among our customers in La Mesa, El Cajon, and Spring Valley who want maximum security on primary entry points while being cost-conscious on secondary doors.
Our technicians carry both rekeying tools and a full inventory of new locks on every call, so we can perform either service, or a combination, during a single visit. We assess the condition of every lock before recommending a course of action and provide transparent pricing for all options. Your security decision should be informed, not pressured. Call (619) 416-2467 for a no-obligation assessment, or visit our residential locksmith page to learn about all the ways we help protect San Diego homes.
When San Diego Homeowners Should Rekey Their Locks
Rekeying your locks is a proactive security measure that should be considered any time the key control for your property has been compromised or is uncertain. Here are the most important scenarios when San Diego residents should schedule a professional rekeying service with Locksmith Magic.
After purchasing a home: This is the number one reason homeowners call us for rekeying. Real estate transactions in San Diego's active market, from the competitive neighborhoods of North Park and South Park to the luxury enclaves of Del Mar and Coronado, often involve multiple parties handling keys. Agents, inspectors, contractors, and previous owners may all have copies. A professional rekey immediately after closing ensures that you and your family are the only people with working keys to your new home.
After a tenant moves out: If you are a landlord or property manager in San Diego, rekeying between tenants is essential. This protects your new tenant's safety and limits your liability. We provide volume rekeying services for multi-unit properties in rental-heavy areas like Pacific Beach, Mission Valley, Clairemont, and Mira Mesa, often completing entire buildings in a single visit.
After losing keys or a theft: If your keys were lost or stolen, whether at the beach in Ocean Beach, at a restaurant in Little Italy, or from your car in a parking structure, rekeying your home locks should be an immediate priority. The cost of rekeying is minimal compared to the potential consequences of unauthorized entry. For urgent situations, we offer emergency rekeying with 15 to 30-minute response times across San Diego.
After a roommate or partner moves out: Domestic situations change, and when someone who previously had legitimate key access to your home no longer should, rekeying provides instant peace of mind. Our technicians handle these calls with discretion and professionalism.
When consolidating to one key: If you have accumulated different keys for different doors over the years, a keyed-alike rekey brings everything under a single convenient key. Many homeowners in older San Diego neighborhoods like Normal Heights, Kensington, and Talmadge find this service especially valuable since their homes may have had locks replaced piecemeal over the decades. Call (619) 416-2467 to schedule your rekeying appointment today, or learn about our full residential locksmith services.

Rekey Locks FAQ: San Diego
How much does it cost to rekey locks in San Diego?
Lock rekeying pricing in San Diego depends on the lock brand, cylinder type, and number of locks being rekeyed. High-security locks with restricted keyways may cost more due to specialized pins and key blanks. We offer discounts when rekeying multiple locks in a single visit. Locksmith Magic provides upfront pricing with no hidden fees, so you know the exact cost before we begin. Call (619) 416-2467 for your free estimate.
What is the difference between rekeying and changing locks?
Rekeying changes the internal pin configuration of your existing lock so that a new key is required. Old keys stop working, but the physical lock hardware stays the same. A lock change involves removing the entire lock and replacing it with brand-new hardware. Rekeying is cheaper and faster since you keep your current locks, while a lock change is appropriate when you want to upgrade security, change lock styles, or replace damaged hardware. Both services result in old keys being rendered useless.
Can you rekey all my locks to use the same key?
Yes, this is called keyed-alike rekeying and it is one of our most popular services. We rekey all of your locks to match a single pin configuration, so one key opens every door, front, back, side, and garage entry. This works with any locks that share the same keyway brand. If you have mixed brands like Schlage and Kwikset, we can either rekey within each brand group or recommend converting one set to match the other. Most homeowners find keyed-alike rekeying extremely convenient.
How long does it take to rekey a lock?
A professional locksmith can rekey a standard residential lock in approximately 10 to 15 minutes per lock cylinder. Simple deadbolts and knob locks are the fastest. More complex locks such as mortise locks or high-security cylinders may take 15 to 20 minutes each. If you are having multiple locks rekeyed to the same key, the process goes faster after the first lock since the same pin configuration is repeated. A typical whole-house rekey of four to six locks takes roughly 45 minutes to an hour.
Should I rekey or change locks when I move into a new home?
At minimum, you should rekey all exterior locks when moving into a new home. You have no way of knowing how many key copies were made by previous owners, real estate agents, contractors, or house sitters. Rekeying is the cost-effective standard recommendation. However, if the existing locks are old, worn, or low quality, upgrading to new locks during your move is a smart investment. Our technician will inspect your locks and give an honest recommendation based on their condition and your security needs.
Do you offer emergency rekeying service in San Diego?
Yes, Locksmith Magic offers emergency rekeying service with response times of 15 to 30 minutes throughout San Diego County. If you need your locks rekeyed urgently, after a break-in, stolen keys, or a domestic safety concern, call us at (619) 416-2467 and we will dispatch a technician immediately. Our mobile units carry complete rekeying kits for all major lock brands so we can rekey your locks on the spot, day or evening, seven days a week. Your safety is our top priority.
Can high-security locks be rekeyed?
Yes, high-security locks from brands like Medeco, Mul-T-Lock, and ASSA can absolutely be rekeyed, but the process requires specialized tools, proprietary pins, and restricted key blanks that standard locksmiths may not carry. Locksmith Magic is fully equipped to rekey high-security cylinders with restricted and patented keyways. These locks use advanced sidebar mechanisms and unique pin designs that demand professional expertise and brand-specific training. Rekeying a high-security lock maintains your significant investment in premium hardware while ensuring that only your newly authorized keys provide access to your property.
