Car key replacement
Replace a lost, damaged, or worn key for the Century sedan, with on-site verification and testing.
Low Rate Locksmith provides Buick Century, a sedan, key replacement across the USA and Canada. If you lost all keys, need a spare, or your remote stopped working, we can identify the Century sedan’s key system, confirm compatibility, and complete cutting and programming on-site when supported.
| Question | Answer |
|---|---|
| Typical cost | Industry-typical pricing varies by year and key system. For a spare metal key, dealer pricing is typically $16-$70; many other Century sedan scenarios (all keys lost, remotes) are commonly quoted by VIN. Mobile locksmith pricing is also typically quoted by VIN; exact price is confirmed at dispatch. $USD; Canadian customers pay the equivalent in CAD. |
| Programming required? | Sometimes. Many 1997-2005 Century sedan keys use GM PK3 immobilizer technology and/or a separate keyless-entry remote; the programming route is confirmed for your vehicle. |
| All keys lost? | Often yes, after we confirm your ID and proof of ownership/authorization and determine whether your Century sedan uses a mechanical key or an immobilizer key. |
| Online fob accepted? | Sometimes, but part numbers/FCC IDs and reusability vary. We check compatibility before we attempt pairing so you don’t pay for programming time on an incompatible remote. |
| What to prepare | Vehicle year, your ID, proof of ownership, your service location, and whether you still have a working key/remote (spare-key work is usually simpler than all-keys-lost). |
Most Century sedan calls fit into a few patterns: loss, wear, or a mismatch between the key/remote and the vehicle’s anti-theft recognition (when equipped). Here’s what we see most often in the USA and Canada as these vehicles age.
For the Century sedan, the goal is simple: identify the correct key system for your exact vehicle, produce a compatible key/remote, and verify lock/unlock/start functions before closeout.
The Century sedan was produced across multiple years, and the key setup can change by year and trim. In practical terms, you’ll typically see one (or more) of the following.
If you’re unsure what you have, we can sort it out on-site. Century sedan key systems can differ between the USA and Canada market configurations, and rules can vary by state and province on what documentation is required.
Not every Century sedan key requires programming, but when an anti-theft system or remote is involved, the right pairing method matters. We also see ignition wear issues that look like a “bad key” at first.
The Century sedan spans decades of GM hardware, so it’s normal for two vehicles with the same badge to use different keys. Later-year vehicles are more likely to use an immobilizer key and a separate remote, while earlier years are more likely to be mechanical-only.
Buick is part of GM’s wider key-system family. In practice, some protocols and part variants are shared across Buick, Chevrolet, GMC, Cadillac, and (in earlier years) Pontiac, Oldsmobile, and Saturn—so we still confirm the exact match for your Century sedan before any programming attempt.
Replace a lost, damaged, or worn key for the Century sedan, with on-site verification and testing.
Pair transponder keys and supported remotes to your vehicle when programming is required.
Help for dead buttons, battery contacts, and remote issues when the housing or electronics are the problem.
Diagnosis when the Century sedan key won’t turn or the ignition cylinder is worn or failing.
Non-destructive entry for lockouts, followed by key replacement options if needed.

If you’re searching for help near you, use our location hub to route into service coverage. We support customers across the USA and Canada through mobile dispatch (availability varies by city and region).
For Canadian customers, documentation rules and acceptable paperwork can differ by province; we’ll explain what’s needed during dispatch.
Where wear commonly shows up first; can cause sticking or no-turn symptoms.
May be worn differently than the ignition; we match cutting to restore smooth operation.
Often overlooked until a spare key is needed; tested during verification when accessible.
Houses ignition components; certain failures can mimic a “bad key.”
The physical blade profile that must match your locks; some later keys are double-sided.
Century sedan key work can be straightforward, but the wrong part or the wrong expectation is what drives rework. These comparisons help you pick a clean path.
| Option | Best for | Watch out for |
|---|---|---|
| Buick dealership | OEM parts and dealer records | Towing, appointments, higher total cost |
| Mobile locksmith | Lost keys, spare keys, no-tow situations | Requires ID, ownership proof, compatible parts |
| Online fob | Possible savings when exact part is known | Used/refurbished fobs may be locked or incompatible |
| DIY programming | Add-a-key for older mechanical/transponder | Not suitable for all-keys-lost or mismatched parts |
Aftermarket remotes can work, but only when the frequency/board revision and FCC ID match what your vehicle expects. OEM remotes reduce guesswork, but cost and availability vary between the USA and Canada.
If the remote fails suddenly, start with the fob battery. If the Century sedan also has no interior electrical response or intermittent crank behavior, the vehicle’s 12V electrical condition may need attention before programming attempts.
These are common patterns for the Century sedan. Exact parts and programming routes are confirmed for your vehicle.
| Years (context) | Key system (typical) | Notes |
|---|---|---|
| 1973-1996 (early years) | Mechanical metal key | Cut-only service is common; lock wear can affect how cleanly a fresh key turns. |
| 1997-2005 (many trims) | Transponder / immobilizer key (GM PK3 on many vehicles) | Often a double-sided blade. Add-a-key and all-keys-lost routes vary and are confirmed for your vehicle. |
| 1997-2005 (when equipped) | Keyless-entry remote (separate fob) | Common FCC IDs encountered on this nameplate include GM39 and L2C0007T, but exact compatibility varies by vehicle configuration. |
Century sedan pricing depends on whether you’re making a spare or starting from zero, and whether your vehicle is mechanical-only or uses an immobilizer (common on many 1997-2005 vehicles). Remote/fob work adds a separate compatibility layer because matching the correct remote matters as much as programming.
Industry-typical; exact price confirmed at dispatch: a spare metal key at a dealer is typically $16-$70. Many other Century sedan scenarios (remotes and all-keys-lost situations) are commonly quoted by VIN, and mobile locksmith pricing is also typically quoted by VIN. All pricing is shown in $USD; Canadian customers pay the equivalent in CAD.
| Factor | Cost impact |
|---|---|
| Spare key with one working key | Usually lower; simpler when we can originate from an existing working key. |
| All keys lost | Usually higher; may require full key origination and immobilizer enrollment on equipped vehicles. |
| Customer-supplied remote/fob | Depends on compatibility and reusability; used remotes can be locked or incorrect. |
| Emergency timing or remote location | May affect the service call cost depending on where you are in the USA or Canada. |
| Vehicle-side issue (battery, ignition) | May require diagnosis before key work can be completed and verified. |
Final pricing is confirmed after the vehicle year, key type, location, authorization, and compatibility are reviewed.
For a Century sedan, we first determine whether it’s mechanical-only or uses GM PK3 immobilizer recognition, then cut and (when supported) enroll a working key after authorization.
This can point to an anti-theft recognition issue on equipped vehicles or an ignition/column problem; we verify which before recommending the next step.
Remote lock/unlock doesn’t prove the ignition key is recognized; we separate remote pairing from immobilizer/start authorization.
Most Century sedan configurations are turn-key. If your vehicle has an aftermarket start system, we diagnose it separately from key cutting and programming.
We check key blank profile and remote/FCC compatibility first so you don’t end up with a non-programmable or wrong-part key.
No ID and proof of ownership/authorization means no cutting, no programming, and no lock manipulation.
We confirm your ID, proof of ownership/authorization, and service location details before any cutting or programming begins.
We identify whether the Century sedan uses a mechanical key, an immobilizer key, and/or a separate remote, then match the correct key blank and remote format.
We cut the key to the correct profile and, if required, enroll it to the vehicle (including GM PK3-related enrollment when applicable) using the appropriate procedure for your configuration.
We verify operation at the vehicle and provide a simple closeout record so you know what was replaced, programmed, and tested.
| Stage | Deliverable | Format |
|---|---|---|
| Vehicle ID | Key-system identification notes (mechanical vs. immobilizer/remote equipped) | On-site verification |
| Authorization | Recorded confirmation of ID + proof of ownership/authorization review | Dispatch/work order record |
| Cutting | Cut key matched to the Century sedan’s locks (when applicable) | Physical key |
| Programming | Transponder/remote enrollment when required and supported | On-vehicle pairing session |
| Verification | Functional tests (lock/unlock/start as applicable to your configuration) | On-site test results |
| Closeout | Summary of parts used and work performed | Receipt / service summary |
We explain whether you need cutting, programming, or both based on the Century sedan’s configuration.
We start with ID and proof of ownership/authorization to protect customers in the USA and Canada.
We validate key blank and remote compatibility before attempting programming.
We test functions at the vehicle so you’re not left guessing what works.
Most Century sedan key work can be completed at the vehicle location, which helps avoid towing in many situations.
Automotive key systems vary by year; we handle mechanical, immobilizer, and remote scenarios every day.
When multiple compatible options exist, we’ll explain OEM vs. aftermarket tradeoffs without forcing a single choice.
You receive a clear closeout summary of what was cut, paired, and tested.
We route you to the correct service path for the Century sedan based on your situation, not a one-size script.
If your Century sedan still has a working key, making a duplicate is usually simpler than an all-keys-lost call.
Most Century sedan vehicles are turn-key; confirming your setup helps avoid ordering the wrong parts.
Unverified remotes can be the wrong FCC ID or be locked. Compatibility checks matter for both USA and Canada vehicles.
Clear access to the driver door and ignition area reduces time spent just getting the vehicle ready for verification and testing.
Low voltage can interrupt pairing and testing. If the vehicle battery is weak, address that before programming attempts.
If you’re not stranded, scheduling can reduce the chance of added service call costs tied to timing or distance.
Share your year + situation and we'll confirm compatibility and a typical price range. Or call the dispatch number directly.
