In simple terms, you keep the same lock, but the old keys will no longer operate on it. Rekeying is a procedure to disassemble the door lock and replace key pins are toggle from inside the lock. 

Key pins have different series, and each series of pins in a lock corresponds to a unique key, so you replace these lock pins with other different pins.

2.Cons of Rekeying

  • Not many security upgrade options: Rekeying locks will only give you a slight increase in security-because you are restricting access to others only through the locks, rather than increasing the inherent security and durability of the locks. If the lock you installed is not perfect and secure, but you rekey the lock, you still get a poor lock and security. This type of change is not as dominant as a security upgrade compared to fully escalating the lock to a more reliable lock.

2.Disadvantages of changing locks

labor cost: Replacing a lock is a more expensive and technically more complicated operation than simply rekeying the lock. If you don’t know how to change locks on the house? Then, In addition to the price of the new lock, you must also pay an additional labor cost, which is usually (even if used alone) more expensive than the full cost of rekeying the key lock. However, with limited budgets, there is no substitute for the security benefits of changing locks for families and business owners.

Cost to Rekey the House

One question you might have with a mind is: Should I change the key or the lock, and how much does it cost to rekey a lock? The average price of rekeying a simple lock in your home is about $ 15 approx. If you want to use multiple locks, and these locks are both the same lock or a lock of considerable complexity, then the price will only increase the cost of each lock. However, not every situation is the same.

Even the most basic locks are quite complex mechanisms. They can become extremely complicated. Is it cheaper to rekey or replace locks? I am going to introduce some common factors that affect the cost of rekeying.

Number of locks

The number of locks will increase your price. Based on the cost of rekeying a lock, multiply by the number of locks you want to re-lock to get the total cost. However, most homeowners do not want the same key to use on all doors of the house. So if you’re going to re-lock a different key, the price will vary, especially if one lock is more complicated than the other. Maybe you are updating your home or apartment security system by installing a master key system. 

Lock change

Not all keys, not even all locks in your home, are the same. For starters, the existing locks in your home are likely to be different, and for security reasons, they will not be all open with a master key. Maybe your front door has a latch, but the garage door may not. These variants will take more time, which in turn will require more money. Inventory your locks in advance (perhaps keeping the tabs with the latches and which ones are not) to better prepare for the price when you get an estimate.

Key update process

Sometimes re-entry locks can be DIY items. Some locks include a kit with the necessary tools. This does not mean it will be easy. This is the wrong move, and you may have to return. The process involves not only removing the door lock from the door in your home, but also removing the door itself, replacing the lock pin to fit your new key, and putting the entire part back in place. This can be tedious and error-prone. Experienced locksmiths can greatly simplify this process, but there are always challenges, so we recommend that you do not do it yourself.

The complexity of locks

Some locks can rekeying DIY styles, but some are more difficult than others. The more complex the lock, the more time it takes, which means that the locksmith’s time cost is higher. The relocking process varies from lock to lock-some will come with lock bolts, some may fit with standard bolt cups, and some may even be high-security locks on the front door. If you don’t necessarily know to determine the complexity of locks, be prepared for price changes in case you find that locks are more complicated than you think.


There is nothing better than old-fashioned debate to help people figure out what they should choose. Hope you are not frustrated by not thinking that one of Rekeying Vs Changing Locks is better than the other, and then urge you to reread this method and re-evaluate your position. Each of these methods is a good solution, depending on the problem you need to solve. As always, take the time to understand your needs, and then go through the points listed above so you can see which service is best for your family.
