You receive two keys when you move into a home. The previous owner may have made more. A neighbor, contractor, cleaner, relative, or house sitter could still have one.
You may never know the exact number of copies. You can still decide which keys should work from this point forward.
On compatible keyed ULTRALOQ models, a qualified locksmith may be able to rekey the cylinder. Rekeying changes the internal pin arrangement so a new key operates the lock and the old key no longer does. You keep the smart lock while changing its physical-key access.
Physical keys do not keep an access history
A smart credential can often be added, removed, or changed through the lock's supported controls. A physical key works differently. The cylinder cannot tell you who copied a key or where each copy went.
Copies can spread during ordinary household life:
- A previous owner gave keys to family members or neighbors.
- A contractor kept a copy during a renovation.
- A cleaner, pet sitter, or former roommate once needed access.
- A key went missing without a clear explanation.
These situations do not prove that someone will misuse a key. They create uncertainty about which copies can still operate the cylinder.
Do you need to rekey every time access changes?
Not every change requires the same response. If a trusted family member returns a key and you know no copies were made, you may decide that no mechanical service is needed. If a key is missing or you cannot account for copies from a previous owner, rekeying gives you a clear new starting point.
Consider the door, the people who had access, and how certain you are about the keys. A locksmith can confirm the mechanical options for the cylinder. You remain responsible for deciding which level of access control fits your household.
Rekeying changes which physical key works
A pin-tumbler cylinder contains spring-loaded pin stacks. The cuts on the correct key lift those pins to the positions that let the cylinder turn.
During rekeying, a qualified locksmith changes the internal pin arrangement to match a new key. The old key still fits the same keyway profile, but its cuts no longer align the pins. It becomes a wrong key for that cylinder.
The exterior smart lock, keypad, fingerprint reader, and other supported credentials do not need to change as part of a standard cylinder rekey. The locksmith works on the compatible mechanical cylinder. Confirm the service process for your model before work begins.
Rekeying is different from copying a key
A duplicate repeats the cuts of a key that already works. Both copies can operate the same cylinder.
Rekeying gives the cylinder a new working pattern. A locksmith provides keys that match the new pinning, while keys cut for the old pinning stop working.
If your goal is to add another trusted key holder, you may need a duplicate. If your goal is to remove access from keys you cannot account for, ask a qualified locksmith whether your compatible model can be rekeyed.
Rekeying is also different from replacing the lock
Replacing a lock removes the existing lock hardware and installs another product. You may need replacement when the hardware is damaged, the product is incompatible with the service you need, or you want a different lock.
Rekeying keeps compatible lock hardware in place and changes the cylinder's internal keying. It can address physical-key access without requiring you to replace the entire smart lock.
A locksmith should inspect the lock and confirm whether rekeying suits the model and condition. Mechanical configurations vary across the ULTRALOQ product family.
Times to consider rekeying
After moving into a home
A new key can establish a clear starting point for physical access. Keys from the prior pinning no longer operate the rekeyed cylinder.
After a key goes missing
You may not know whether someone found the key or where it was lost. Rekeying can make that missing key stop working on a compatible cylinder.
After household or service access changes
A former roommate, contractor, cleaner, or caregiver may no longer need entry. Rekeying can remove the old physical-key access when collecting every copy is impractical.
Digital credentials need separate attention. Review the users, codes, fingerprints, cards, or app access supported by your lock when household access changes.
A familiar keyway can help the conversation
Select keyed ULTRALOQ models use a Schlage C keyway compatible profile. Many U.S. locksmiths recognize this widely used profile, which can make common key and service conversations more familiar.
Compatibility describes the keyway profile. It does not mean Schlage manufactures the ULTRALOQ cylinder, and it does not guarantee that every locksmith offers the same service for every model.
Before scheduling work, identify your ULTRALOQ model and tell the locksmith that you want to change which physical key operates the cylinder. Ask the locksmith to confirm compatibility and provide the number of new keys your household needs.
Plan the change before the locksmith arrives
A short access review can help you prepare:
- Confirm the exact ULTRALOQ model on the door.
- Count the household members who need a new physical key.
- List other exterior doors that may need separate attention.
- Review the digital users and credentials supported by your lock.
- Ask a qualified locksmith to confirm that the cylinder can be rekeyed.
Do not assume that rekeying one door changes another lock. Each cylinder keeps its own pinning unless a locksmith services it as part of the same plan.
Plan all exterior doors together
Your front door may be only one physical entry point. A side door, garage entry, or back door may use a separate key and cylinder. Changing the front-door key does not remove access through another door.
Walk through the exterior entries before arranging service. Note which doors have keyed cylinders, which keys operate them, and which household members use each entrance. Give that information to the locksmith when discussing the work.
Some compatible cylinders may support a keyed-alike plan, but support depends on the models, keyways, and service available. Ask the locksmith to inspect the locks instead of assuming that one key can operate all of them.
Check the result before service ends
Test the new key from both sides of the door where the design allows it. Confirm that the cylinder turns without binding and that the deadbolt extends and retracts as expected. Then test an old key to confirm that it no longer operates the rekeyed cylinder.
Store the new keys with the people who need them and avoid labeling a spare with the full home address. Review the lock's digital users as a separate step so physical and smart access reflect the same household plan.
Mechanical access should support life after setup
A front door often stays in place while the people around it change. ULTRALOQ considers that ownership timeline on compatible keyed models through a familiar keyway and a cylinder that a qualified locksmith may be able to rekey.
The value is practical: you can keep using the smart access methods that suit your household while changing the physical key when access needs change.
Frequently asked questions
Will rekeying make every old copy stop working?
A proper rekey changes the cylinder so keys cut for the old pinning no longer operate it. Ask the locksmith to test the old and new keys before completing the service.
Does rekeying delete codes, fingerprints, or app users?
A cylinder rekey addresses physical-key access. Review and update digital credentials through the controls supported by your ULTRALOQ model.
Can every keyed ULTRALOQ model be rekeyed?
Mechanical configurations vary. A qualified locksmith may be able to rekey compatible keyed ULTRALOQ models. Confirm your model before arranging service.
Can one new key operate several exterior doors?
Keyed-alike service depends on compatible cylinders, keyways, models, and the locksmith's service plan. Do not assume that every ULTRALOQ lock or other door lock can share one key.
