Hiring a Locksmith to Change House Locks: Rekey or Replace?
If you need a locksmith to change house locks, the first decision is whether the locks actually need to be replaced. In many cases, rekeying the existing hardware gives you new keys and blocks the old ones for less cost. In other cases, damaged, outdated, or low-security locks should be replaced.
The best choice depends on why you are calling, the condition of the door hardware, and the level of security you want after the job is done.
When to change your house locks
A lock change or rekey is smart after moving into a new home, losing keys, ending a roommate or tenant arrangement, finishing major contractor work, or dealing with a break-in. You should also update locks that are sticking, rusted, loose, or hard to operate.
If a lock is failing mechanically, do not wait until it strands you outside. A stiff key, loose cylinder, wobbling knob, or deadbolt that does not throw cleanly can turn into a lockout or security failure.
Rekeying vs replacing locks
Rekeying changes the pins inside the cylinder so old keys stop working and a new key operates the lock. You keep the existing hardware. This is often the right option when the lock is in good condition and your goal is access control.
Replacing a lock removes the old hardware and installs a new lockset, deadbolt, smart lock, or high-security cylinder. Replacement is better when the existing lock is worn, damaged, low quality, mismatched, or not strong enough for the door.

What a professional lock change includes
A locksmith should inspect the door, frame, strike plate, cylinder, latch, and deadbolt alignment before recommending hardware. If the door is misaligned, a new lock may still feel difficult to use unless the strike or hinge problem is corrected.
A proper visit should include clear pricing, hardware options, installation or rekeying, new keys, testing from both sides of the door, and basic care instructions. If smart locks or high-security locks are being installed, the technician should also confirm backup access and key control.
Choosing the right lock
For most homes, a good deadbolt is still the foundation. Look for solid construction, proper strike reinforcement, and a lock grade that matches the risk level of the door.
Smart locks add convenience, temporary codes, and remote control, but they still need a strong mechanical installation. High-security locks add resistance to picking, drilling, bumping, and unauthorized key duplication. They are a good fit when key control matters or when the existing door is a primary entry point.
How much does a lock change cost?
Cost depends on the number of locks, the type of hardware, whether you rekey or replace, the complexity of the door, and whether the visit is scheduled or emergency service. Rekeying is usually less expensive because it uses the current hardware. New high-security or smart hardware costs more but may provide better long-term value.
Always ask for the service call, labor, and hardware cost before work begins. A low phone quote that excludes parts, labor, or after-hours rates is not a real quote.
FAQ
Should I rekey or replace locks after moving in?
If the locks are in good condition, rekeying is usually enough to stop old keys from working. Replace them if they are worn, weak, damaged, or not secure enough.
Can one key work all my house locks?
Often, yes, if the locks are compatible. A locksmith can key multiple cylinders alike or explain when hardware differences prevent it.
Should I change locks after losing keys?
Yes, especially if the keys may be tied to your address. Rekeying is often the fastest way to make the lost keys useless.
