Car key replacement
Cut replacement keys and enroll them when the Sierra pickup’s security system requires it.
Low Rate Locksmith provides GMC Sierra, a pickup truck, key replacement and mobile locksmith service across the USA and Canada. This page covers common Sierra pickup key types (metal keys, transponder keys, remotes, and push-to-start smart keys where equipped), what usually requires programming, and what you’ll need for authorized service.
| Question | Answer |
|---|---|
| Typical cost | Industry-typical ranges vary by year and key type. Examples: spare metal key $10-$35; spare transponder key $60-$180; transponder all-keys-lost $120-$300. Many remote and smart-key situations are quoted by VIN (dealer and mobile). Exact price is confirmed at dispatch; Canadian customers pay the equivalent in CAD. |
| Programming required? | Sometimes. Many 2007+ Sierra pickup configurations use an immobilizer system that may require key enrollment; remotes and smart keys also vary by year and trim. |
| All keys lost? | Often serviceable on-site after photo ID and proof of ownership/authorization are confirmed, then the correct key system is matched to your truck. |
| Online fob accepted? | Sometimes, but part number/FCC ID and whether it’s locked/used must be confirmed before a locksmith can program it. |
| What to prepare | Vehicle year, VIN (recommended), photo ID, proof of ownership/authorization, your location, and any remaining keys/fobs (even damaged). |
Cut replacement keys and enroll them when the Sierra pickup’s security system requires it.
Pair transponder keys and some smart keys to the truck’s immobilizer when supported.
Address worn buttons, battery contacts, and shell issues before you replace the remote.
Authorized entry when keys are inside the Sierra pickup or the remote won’t unlock.
Remove a snapped blade from the ignition cylinder or door lock without forcing parts.
Diagnose key-fit and cylinder wear when the key turns poorly or won’t turn at all.
The Sierra pickup spans multiple generations, trims (including 1500/2500HD/3500HD and Denali), and key options. Some years are basic metal keys with separate remotes, while other years use a transponder/immobilizer system (GM PK3 is one system seen in certain bands). Newer push-to-start configurations may use a proximity-style smart key.
Because remotes, transponder chips, and FCC IDs can change within the same model year, a VIN-based match is the cleanest way to prevent wrong-part issues for customers in both the USA and Canada.
Knowing which component is failing helps separate “key problem” from “truck-side problem.” These are common Sierra pickup components involved in key and lock service.
Where a mechanical key inserts; wear can cause hard turning or inconsistent key feel.
Pin-tumbler door cylinders that can be rekeyed or repaired on some configurations.
May be keyed to match the doors or actuated electronically depending on trim.
Receives remote commands; pairing method depends on year and remote type.
Mechanical steering lock components can bind if the wheel is loaded against the lock.
Most Sierra pickup key problems come down to compatibility, authorization, and whether programming is required. These decision points help avoid paying twice.
| Option | Best for | Watch out for |
|---|---|---|
| GMC 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 modern Smart Key |
Aftermarket can work, but only when the chip type and FCC ID match and the fob isn’t previously locked. For Canada and USA customers, the safest path is to confirm compatibility before cutting or attempting enrollment.
If a blade snaps, extraction is usually attempted first. If the cylinder is worn or damaged, it may be more cost-effective to address the cylinder so the replacement key doesn’t bind or wear prematurely.
These bands reflect common Sierra pickup configurations and known chip/FCC examples. Final compatibility depends on your exact year, trim, and equipment, and is commonly confirmed by VIN for USA and Canada service.
| Years (context) | Key system (typical) | Notes |
|---|---|---|
| 1999-2006 | Mechanical metal key + separate remote (no immobilizer typical) | Examples seen: standard key FCC B102 or GM39; remote FCC examples include KOBLEAR1XT, KOBUT1BT, LHJ011, AB01502T. Many items are quoted by VIN. |
| 2007-2013 | Transponder / immobilizer key (GM PK3) + optional remote | Transponder example: chip ID46, FCC B111. Add-a-key and all-keys-lost procedures may be onboard; confirmed for your truck. |
| 2014-2018 | Remote keyless entry (remote type varies) | Remote example: FCC M3N32337100. Whether an immobilizer key is present depends on configuration; many items are quoted by VIN. |
| 2019-2026 | Smart key system / push-to-start (proximity) (GM PK3) | Examples seen: chip PCF7937E; FCC HYQ1ES or HYQ1EA. Enrollment commonly uses OBD; confirmed for your vehicle. |
Pricing on the Sierra pickup is driven by (1) whether you’re making a spare or starting from zero, (2) whether programming is required, and (3) whether the truck uses a basic key, a transponder key (GM PK3 on some year bands), or a push-to-start smart key.
Industry-typical ranges (USD): spare metal key $10-$35; spare transponder key $60-$180; transponder all-keys-lost $120-$300. Many remote and smart-key scenarios are commonly quoted by VIN (dealer and mobile locksmith). Canadian customers pay the equivalent in CAD.
| Factor | Cost impact |
|---|---|
| Spare key with one working key | Usually lower, especially when a simple metal spare is supported. |
| All keys lost | Usually higher due to origination and additional programming steps. |
| Smart key / push-to-start (2019+ trucks) | Usually higher; many jobs are quoted by VIN due to part and programming variation. |
| Customer-supplied fob | Depends on compatibility (FCC ID, chip type, and whether the fob is locked/used). |
| Emergency timing or remote location | May affect the service call cost. |
| Vehicle-side issue (battery, ignition) | May require diagnosis before key work can be completed. |
Final pricing is confirmed after the vehicle year, key type, location, authorization, and compatibility are reviewed.
On many Sierra pickup years, creating a new working key means cutting plus enrolling to the immobilizer (when equipped), after ID and ownership are confirmed.
If the blade turns but the engine won’t start, it can point to a transponder/immobilizer mismatch or a truck-side start/ignition issue.
Lock/unlock can work even when the transponder or smart-key portion isn’t recognized; diagnosis starts with confirming the key type for your year.
For push-to-start Sierra pickup trims, a proximity smart key may need pairing, a battery, or compatibility correction before the truck will start.
If an online key/fob doesn’t match the correct FCC ID or chip type, it may not program even if it looks identical.
Start with the fob battery and the truck’s 12V battery, then confirm the smart key’s FCC ID/chip and check for start-system faults if pairing fails.
Without valid ID and proof of ownership/authorization, Low Rate Locksmith will not cut, program, or unlock a vehicle.
ID and proof of ownership/authorization are confirmed first. This is required in the USA and Canada, with details varying by state and province.
The Sierra pickup’s year/trim determines whether you need a basic key, transponder key, remote, or proximity smart key. FCC ID and chip type are checked before programming.
Cutting is performed when applicable, then the key is enrolled to the GM PK3 immobilizer through OBD-II or an approved onboard method when supported by that system.
Start, lock/unlock, and remote functions are tested as equipped. Results and parts used are documented for your records.
| Stage | Deliverable | Format |
|---|---|---|
| Vehicle ID | Confirmed year/trim context and key system direction (based on the details provided) | On-site checklist |
| Authorization | Documented confirmation of ID and ownership/authorization | Dispatch and on-site record |
| Cutting | Cut key blade (when applicable) verified for physical operation | Physical key + notes |
| Programming | Enrolled transponder or smart key (when required by the Sierra pickup) | Programming log |
| Verification | Start test and lock/unlock/remote function checks (as equipped) | On-site test steps |
| Closeout | Clear summary of work performed and parts used | Receipt / closeout notes |
Key type, likely programming needs, and next steps are explained before any cutting or enrollment.
ID and proof of ownership/authorization are required. This applies to U.S. and Canadian customers, with local rules varying by state and province.
FCC ID/chip type checks help prevent “looks right, won’t program” outcomes.
Start and remote functions are tested on-site when the truck supports them.
Designed for no-tow situations: lost keys, spare keys, and on-site pairing when supported.
Automotive key systems change by year band; the workflow focuses on identifying the right system first.
OEM and compatible aftermarket options may be available depending on your year/trim and inventory.
Receipts and basic closeout notes help when you need a second spare later.
Supports many Sierra pickup configurations (1500/2500HD/3500HD and Denali) based on year/trim and equipment.
Spare-key work is usually simpler than all-keys-lost service, especially on transponder and smart-key Sierra pickup years.
Push-to-start smart keys and turn-key blades are different systems. Confirm what your truck uses before ordering a fob.
If you buy online, match FCC ID and chip type and avoid used/locked fobs. If uncertain, get compatibility checked first.
Programming usually requires access to the truck and a stable work area near the driver’s side.
Low 12V battery voltage can interrupt enrollment on some systems. A healthy battery helps prevent incomplete programming.
When timing is flexible, you can often avoid higher service call costs tied to urgent dispatch windows or remote travel.
