Understanding the rekeying vs changing locks cost can help homeowners and businesses make the right security decision for their property in Chicago. After moving into a new home, losing keys, or upgrading property security, many people wonder if rekeying locks or replacing them completely is the better option. Rekeying is usually more affordable because the existing lock hardware remains in place, while changing locks involves installing new hardware for added protection and updated security features. The total lock rekeying cost depends on the lock type, labor, and security level required. This guide explains pricing differences, security benefits, and when each option makes the most sense.
Rekeying Vs Changing Locks Cost in Chicago
Rekeying is generally more affordable because a locksmith modifies the internal pins of the existing lock so old keys no longer work. Changing locks cylinder requires completely replacing the hardware, which increases both labor and material costs.
| Service | Average Cost in Chicago |
| Rekey One Lock | $20 – $50 |
| Rekey Multiple Locks | $80 – $250 |
| Standard Lock Replacement | $75 – $180 |
| High-Security Lock Installation | $150 – $350 |
| Smart Lock Replacement | $180 – $450 |
Professional locksmith services also ensure the locks are properly secured and functioning correctly after the work is completed. Choosing the right option can improve property security, prevent unauthorized access, and provide long-term peace of mind for homeowners and businesses.
When Rekeying Locks Is the Better Option?
Rekeying locks is often the best solution when your existing lock hardware is still in good condition, but you want to improve security and prevent old keys from working. Compared to full lock replacement, rekeying is faster, more affordable, and highly effective for residential and commercial properties in Chicago.
Many homeowners choose rekeying after moving into a new home, losing their keys, or during tenant and employee turnover. It is also a practical option for property owners who want all doors keyed alike for easier access management. Professional locksmith rekeying services provide reliable security upgrades without the higher cost of installing completely new lock systems.
When Changing Locks Makes More Sense?
Changing locks is recommended when the existing hardware is damaged, outdated, or no longer provides the level of security you need. Replacing locks allows property owners to upgrade to stronger deadbolts, smart locks, or modern high-security systems.
Situations where lock replacement is the better option:
- Broken or worn-out locks
- Upgrading to smart lock technology
- Locks damaged after a break-in attempt
- Old locks with poor security ratings
- Matching new door hardware designs

Both services improve security, but they offer different advantages depending on your property’s condition and protection requirements.
| Feature | Rekeying Locks | Changing Locks |

| New Hardware Installed | No | Yes |
| Stops Old Keys From Working | Yes | Yes |

Rekeying also helps reduce costs while maintaining the existing lock’s appearance and functionality. For many property owners in Chicago, it is an efficient way to improve security without replacing every door lock.
How Long Does Rekeying or Lock Replacement Take?
The time required depends on the number of locks, the lock type, and the condition of the hardware. Rekeying is usually faster because the locksmith works with the existing lock components rather than removing and installing new hardware. Average service times:
- Rekeying one lock: 10–20 minutes
- Rekeying an entire home: 30–90 minutes
- Standard lock replacement: 20–45 minutes per lock
- Smart lock installation: 45–90 minutes
Conclusion
Choosing between rekeying and replacing locks depends on your security goals, budget, and the condition of your existing hardware. If your locks are functioning properly and you simply want to disable old keys, rekeying is usually the faster and more affordable option. However, if your locks are damaged, outdated, or you want upgraded protection, changing locks may provide better long-term security.
