Car key replacement
Replace lost, broken, or damaged keys, including chip keys and remotes when supported by your vehicle’s system.
Low Rate Locksmith provides Ford Explorer Sport Trac key replacement and mobile locksmith service across the USA and Canada. We help with lost keys, spare keys, fob issues, and ignition-related key problems, with authorization checks and on-site testing before closeout.
| Question | Answer |
|---|---|
| Typical cost | Typical Cost Range: $120-$550 (industry-typical; exact price confirmed at dispatch). Price depends on year, key type, whether all keys are lost, parts, programming needs, and your location in the USA or Canada (Canadian customers pay the CAD equivalent). |
| Programming required? | Often yes. Explorer Sport Trac keys commonly involve an immobilizer/transponder system (Ford PATS family), and remotes/proximity fobs (when equipped) must be paired to the vehicle. |
| All keys lost? | Usually, yes—after we confirm ID and proof of ownership/authorization, we identify the key system and create a working key (when supported by the vehicle’s system). |
| Online fob accepted? | Sometimes. Customer-supplied fobs and keys must be the correct part type and in a programmable state; used/remanufactured units are a common compatibility problem. |
| What to prepare | Vehicle year, your location, a government-issued photo ID, proof of ownership/authorization, and whether you have a working key/fob. |
Replace lost, broken, or damaged keys, including chip keys and remotes when supported by your vehicle’s system.
Enroll transponder keys and pair remotes/fobs to the vehicle after compatibility is confirmed.
Diagnose common fob problems like dead batteries, damaged shells, and pairing issues.
Address key-won’t-turn and ignition-cylinder wear issues that can mimic a “bad key.”
Regain entry without damaging door hardware when keys are locked inside.
Remove a snapped key from the door or ignition, then cut a replacement as appropriate.
Explorer Sport Trac owners usually call us for a short list of repeat issues: lost keys, chip-key starting problems, remote trouble, and ignition wear. Because Ford security equipment varies by year/trim and by USA vs Canada market configuration, we confirm the exact system before we cut or program anything.
We keep Explorer Sport Trac key work documented and test-driven: confirm authorization, identify the system, perform the cutting/programming steps that apply, then verify lock/unlock and start behavior before closeout. This approach is the same whether you’re in the USA or Canada.
Ford Explorer Sport Trac keys are commonly more than “just a metal key.” Depending on the vehicle configuration, you may have a chip key, a separate remote/fob, or a combined head key. The exact format varies by year, trim, and market.
Explorer Sport Trac “no start” and “won’t turn” complaints can be key-related, ignition-related, or security-system related. We separate those causes before recommending replacement parts, and we avoid any approach that bypasses anti-theft systems.
Ford commonly uses the PATS (Passive Anti-Theft System) immobilizer family across cars and trucks, and that security layer changes how key replacement works. On the Explorer Sport Trac (2001-2010), keys and remotes can differ by trim and by USA vs Canada market configuration, so we confirm what you have before we proceed.
If you’re unsure what you have, we can still help: we’ll identify whether your setup is a standard turn-key transponder, a turn-key + remote arrangement, or a proximity-style fob (where equipped) and then quote based on that confirmed system.
Key replacement problems often come from a small set of components interacting: the cut of the key, the immobilizer recognition, and the physical lock hardware. Here are the main parts we evaluate during service.
Mechanical part the key turns; wear here can cause sticking or no-turn complaints.
Need to match the cut key for manual entry and mechanical verification.
May be keyed differently on some vehicles; we confirm function during verification.
The physical blade profile must match the Ford-specific blank used by your locks.
Binding or internal wear can mimic key/remote issues and affects lock/unlock verification.
Explorer Sport Trac key work goes smoother when you pick the right path for your situation: spare vs all-keys-lost, dealer vs mobile, OEM vs aftermarket, and “battery problem” vs “programming problem.” The goal is fewer surprises at the vehicle in the USA or Canada.
| Option | Best for | Watch out for |
|---|---|---|
| Ford 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 shells and remotes can work, but the risk is wrong board/part type or a fob that can’t be enrolled. If you bring your own part, we check compatibility first and only proceed if it’s programmable for your vehicle’s system.
A dead fob battery is common, but it’s not the only cause. Low vehicle 12V voltage, prior programming changes, or a mismatched fob can create “remote not working” symptoms even with a new battery.
Explorer Sport Trac key systems can vary by year, trim, and market. The table below is a practical way to think about what you might have, and why the on-site plan changes between key types.
| Years (context) | Key system (typical) | Notes |
|---|---|---|
| 2001-2010 (turn-key setups) | Transponder / immobilizer (Ford PATS family) | If the chip is not recognized, the engine may crank without starting even if the key is cut correctly. |
| 2001-2010 (remote-equipped trims) | Transponder key + remote/fob | Remote lock/unlock can fail from battery, damage, pairing, or part mismatch; the mechanical key and the remote are separate functions. |
| 2001-2010 (where equipped) | Smart key system / push-to-start | Requires fob enrollment to the vehicle; customer-supplied fobs are more likely to be incompatible or previously locked. |
Typical Cost Range: $120-$550 (industry-typical; exact price confirmed at dispatch). Even within the same model, price changes based on whether you’re adding a spare or starting from zero, whether the vehicle uses a transponder key or a fob system, and whether there’s an ignition/lock hardware problem that must be handled first.
For transponder-key scenarios, both dealerships and mobile locksmiths commonly quote by VIN (especially for all-keys-lost and spare-key situations), because the correct parts and programming path depend on the vehicle’s security configuration. This applies for customers in both the USA and Canada (Canadian customers pay the CAD equivalent).
| Factor | Cost impact |
|---|---|
| Spare key with one working key | Usually lower because the vehicle is already accessible and key enrollment can be simpler. |
| All keys lost | Usually higher due to key origination, immobilizer enrollment, and additional verification steps. |
| Smart Key / push-to-start (where equipped) | Usually higher because fobs require enrollment and parts compatibility is less forgiving. |
| Customer-supplied fob | Depends on compatibility and whether the unit is new/programmable for your specific vehicle setup. |
| Emergency timing or remote location | May affect the service call portion of the total, 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.
If you’re searching from a specific city or region, route through our location layer so dispatch can match you with a mobile technician and confirm what’s supported for your vehicle configuration. This is used for both USA and Canada coverage, and availability can vary by U.S. state and Canadian province.

We identify the Sport Trac key system (PATS/transponder or fob system), verify authorization, then originate and program a working key when the vehicle supports it.
This often points to an immobilizer/transponder recognition issue rather than the blade cut; we diagnose before replacing parts.
Remote buttons can work even when the transponder/proximity credential is not accepted; we verify the start authorization path.
On push-to-start-equipped vehicles, the fob must be compatible and enrolled, and the vehicle’s 12V system must be stable for reliable detection.
If you bought a key/fob online, we check whether it’s the correct type and programmable before we attempt pairing.
We check fob battery condition, vehicle 12V voltage, fob compatibility, and whether a start-system fault is blocking recognition.
No ID and proof of ownership/authorization means we do not cut, program, or originate keys.
We check photo ID and proof of ownership/authorization, then confirm the service request at the vehicle in the USA or Canada.
We identify the key system and confirm the part type needed so we don’t waste time programming the wrong fob/key.
We cut (when applicable) and then program/enroll the key into the Ford PATS-family immobilizer or pair the remote/fob when supported.
We verify functions at the vehicle, then provide a documented closeout so you know what was completed.
| Stage | Deliverable | Format |
|---|---|---|
| Vehicle ID | Confirmed vehicle details and key system direction | On-site confirmation |
| Authorization | Documented ID + ownership/authorization check | Photo/notes captured per job record |
| Cutting | Key cut to match locks/ignition (when applicable) | Physical key |
| Programming | Transponder/remote/proximity enrollment when required | Vehicle programming session |
| Verification | Lock/unlock/start checks and basic functional validation | On-site tests |
| Closeout | Documented completion and next-step notes if issues remain | Receipt and job summary |
We confirm the request and the likely key system before we cut or program, so you know what’s being attempted.
ID and proof of ownership/authorization are required for every key origination or programming job in the USA and Canada.
We verify part type and programmability before pairing, especially for customer-supplied keys and fobs.
We test locks and starting behavior at the vehicle before the job is closed.
Most key replacement and programming steps are performed on-site to reduce towing and downtime.
We focus on automotive key systems, including Ford’s PATS-family immobilizer behavior and common failure patterns.
When multiple part paths exist (key + remote vs integrated remote), we’ll explain what your vehicle supports.
You get a receipt and a plain-language summary of what was cut/programmed and what was verified.
We route model-specific help into the correct service line: key replacement, programming, lockout, or ignition.
Adding a spare key while you still have one working key is usually simpler than an all-keys-lost origination.
Explorer Sport Trac configurations can differ. Knowing whether you have a standard turn-key transponder or a proximity-style fob changes parts and programming.
If you order online, match the exact part type first. Used fobs are commonly the wrong board type or not enrollable.
Clear access to the driver door and ignition area reduces time spent just reaching the work area, especially during lockout or all-keys-lost calls.
Low 12V voltage can interrupt programming and cause false “key not detected” symptoms on some systems.
When timing is flexible, it can reduce the chance of added costs tied to emergency dispatch or remote travel in the USA or Canada.
