Car key replacement
Replacement keys for turn-key and push-to-start systems, based on year band and parts compatibility.
Low Rate Locksmith provides Ford Fusion, a sedan, key replacement and mobile locksmith service across the USA and Canada.
| Question | Answer |
|---|---|
| Typical cost | Industry-typical ranges depend on year and key system: remote key (spare) dealer $200-$450 vs mobile locksmith $100-$250; remote key (all keys lost) dealer $300-$600 vs mobile locksmith $150-$350; smart key (spare) dealer $250-$450 vs mobile locksmith $150-$300; smart key (all keys lost) dealer $350-$700 vs mobile locksmith $200-$450. Pricing is in $USD; Canadian customers pay the equivalent in CAD. |
| Programming required? | Often yes. Many Fusion sedans use Ford PATS immobilizer programming for remote keys and push-to-start smart keys. |
| All keys lost? | Often serviceable on-site after government-issued ID and proof of ownership are verified, then a new key is cut and enrolled to the immobilizer. |
| Online fob accepted? | Sometimes. Customer-supplied keys/fobs must match the Fusion sedan’s year band, frequency, and chip type, and some used units will not enroll. |
| What to prepare | Vehicle year, your location (ZIP/postal code), government-issued ID, registration/title (or authorized documents), and whether you have a working key. |
Replacement keys for turn-key and push-to-start systems, based on year band and parts compatibility.
Enroll a transponder key or smart key to the immobilizer so the Fusion sedan will start.
Help for lock/unlock issues, battery contacts, and fob function troubleshooting.
Non-destructive entry when keys are locked inside the Fusion sedan.
Diagnosis when the key turns poorly, the cylinder binds, or the vehicle won’t recognize a known-good key.
Remove a broken blade segment from an ignition or door lock, then cut a replacement key.
Ford Fusion sedans commonly use Ford PATS (Passive Anti-Theft System), which means the vehicle must recognize the correct transponder or smart key before it will start. Depending on year and trim, you may have a turn-key remote key (key + remote combined) or a push-to-start smart key (proximity fob). Both can require programming during replacement, especially for all-keys-lost situations.
The cut metal portion that mechanically operates door and ignition cylinders on turn-key setups.
The anti-theft chip that must match the immobilizer’s stored data for starting authorization.
Lock/unlock/trunk functions that may require pairing separate from start authorization.
Vehicle-side antennas that detect a compatible smart key inside/near the cabin.
Mechanical component that can wear; problems here can mimic “bad key” symptoms.
Diagnostic access point commonly used to enroll keys to PATS when required by the year band.
The right next step depends on whether you still have a working key, whether the car is push-to-start, and whether your issue is “can’t start” vs “remote buttons don’t work.” The comparisons below help you choose a path that avoids incompatible parts and repeat programming.
| 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 |
If you’re sourcing your own part, compatibility is more important than branding. For the Fusion sedan, the correct frequency, chip family, and whether the fob is “new/virgin” (not previously locked to another vehicle) determine whether programming can succeed.
A worn ignition cylinder, low vehicle voltage, or a start-system fault can mimic a key issue. If the Fusion sedan intermittently recognizes the key or shows inconsistent symptoms, diagnosis may be needed before replacing parts.
Ford Fusion key systems vary by year, trim, and market (USA and Canada). The table below reflects common configurations and the programming approach typically used.
| Years (context) | Key system (typical) | Notes |
|---|---|---|
| 2006-2010 (turn-key era) | Remote key + transponder (Ford PATS) | Chip: 4D63. Add-a-key: onboard. All keys lost: OBD programming typically used. |
| 2010-2012 (turn-key remote key) | Remote key + transponder (Ford PATS) | Chip: 4D63. FCC: 2011+ FO38R. Add-a-key: onboard. All keys lost: OBD programming. |
| 2013–2026 (turn-key remote key) | Remote key + transponder (Ford PATS) | Chip: ID49. FCC: 315MHz. Add-a-key: OBD. All keys lost: dealer-only on some trims/configurations (confirmed for your vehicle). |
| 2013–2026 (push-to-start trims) | Smart key / push-to-start (Ford PATS) | Chip: ID49. FCC: -2017 315MHz or -2017 902MHz. Add-a-key: OBD. All keys lost: OBD on supported configurations (confirmed for your vehicle). |
| 2017-2020 (push-to-start smart key) | Smart key / push-to-start (Ford PATS) | Chip: ID49. FCC: 315MHz or 902MHz. Add-a-key: OBD. All keys lost: OBD on supported configurations (confirmed for your vehicle). |
Ford Fusion key pricing depends mainly on (1) whether you have a working key, (2) whether your Fusion sedan uses a turn-key remote key or a push-to-start smart key, and (3) whether programming is required to enroll the key to Ford PATS. Travel distance, parts availability, and the condition of locks/ignition can also affect the total.
Below are industry-typical ranges for dealer vs mobile locksmith service (not a quote). Pricing shown is in $USD; Canadian customers pay the equivalent in CAD. Exact pricing is confirmed at dispatch after the year band, key type, and compatibility are reviewed.
| Scenario | Dealer (industry-typical) | Mobile locksmith (industry-typical) |
|---|---|---|
| Remote key (spare) | $200-$450 | $100-$250 |
| Remote key (all keys lost) | $300-$600 | $150-$350 |
| Smart key (spare) | $250-$450 | $150-$300 |
| Smart key (all keys lost) | $350-$700 | $200-$450 |
| Factor | Cost impact |
|---|---|
| Spare key with one working key | Usually lower than originating keys from zero. |
| All keys lost | Usually higher due to immobilizer enrollment and extra verification steps. |
| Smart key / push-to-start (2013–2026 trims) | Usually higher because parts and programming are more involved than basic transponder setups. |
| Customer-supplied fob | Depends on compatibility and whether the fob is new/programmable. |
| Emergency timing or remote location | May affect the service call cost in the USA and in Canada. |
| Vehicle-side issue (battery, ignition) | May require diagnosis before key work can be completed. |
Final pricing is confirmed after the vehicle year band, key type, location, authorization, and compatibility are reviewed.
On many Fusion sedans, a new key must be cut and then enrolled to Ford PATS so the vehicle will start.
This can indicate an immobilizer mismatch (PATS) or a key chip issue rather than a cutting problem.
Lock/unlock can function even when the transponder/smart key isn’t authorized to start the Fusion sedan.
For push-to-start trims, proximity detection and smart key enrollment must match the vehicle’s system.
Aftermarket and refurbished fobs vary; compatibility checks help avoid parts that won’t program.
Common causes include a weak fob battery, low vehicle 12V battery, incompatible fob/frequency, or a start-system issue on the Fusion sedan.
If ID and ownership can’t be verified, the job stops before cutting, programming, or entry service.
Before cutting or programming, we confirm the Fusion sedan and verify ID + proof of ownership. Requirements can vary by U.S. state and Canadian province.
We identify whether your Fusion sedan uses a remote key or smart key, then confirm chip family and frequency so parts match.
If a cut key is required, we cut it to match the locks. When programming is required, we enroll the key to Ford PATS using the appropriate method for your year band.
We verify starting, locking, and requested remote functions (as applicable), then provide a documented closeout summary.
| Stage | Deliverable | Format |
|---|---|---|
| Vehicle ID | Confirmed Fusion sedan key system path (remote key vs smart key) | On-site assessment |
| Authorization | ID + proof-of-ownership check completed before work | Document review |
| Cutting | Key blade cut to match locks when required | Physical key |
| Programming | Key enrolled to Ford PATS when required for start authorization | Electronic enrollment |
| Verification | Start/lock/unlock/remote functions tested as applicable | Functional test |
| Closeout | Documented results and next-step guidance if a vehicle-side issue is found | Job summary |
We confirm whether you need cutting, programming, or both based on the Fusion sedan’s key system.
ID and proof of ownership come before key origination or immobilizer enrollment.
Chip family and frequency mismatches are a common cause of failed programming; we check first.
We test what we serviced (start and requested remote functions) before we wrap up.
On-site service is designed to reduce towing and coordinate around your location when service is available.
Automotive key work involves immobilizers, remotes, and ignition hardware—handled as one system.
Depending on the Fusion sedan’s year band, we may support compatible OEM or aftermarket options.
You get a clear record of what was cut/programmed and what was tested.
We coordinate service across the USA and Canada; availability varies by location and is confirmed at booking.
If you still have one working key, adding a spare is usually simpler than originating keys after all keys are lost.
Fusion sedans can use either system depending on trim. Confirming this up front helps avoid ordering the wrong fob.
Used/refurbished fobs may be locked. If you buy online, match the year band and frequency and expect a compatibility check.
Clear access to the driver door and OBD-II area helps the technician complete cutting/programming without delays.
Low battery voltage can interrupt programming on PATS-equipped vehicles. If the Fusion sedan battery is weak, address it first.
Non-emergency scheduling can reduce the chance of additional dispatch charges based on timing or distance in the USA and Canada.
These are examples of key/fob product types that may match certain Fusion sedan configurations. Compatibility depends on year band and system type (remote key vs smart key), and programming enrollment may still be required.
Common turn-key remote style. Must match chip/frequency and be programmable for your Fusion sedan.
Refurbished units may be re-usable when properly prepared, but some are locked and cannot be enrolled.
Used on push-to-start trims. Smart key compatibility must be confirmed before programming.
Make-level guidance for Ford keys, programming, and related help.
Key replacement, programming, lockouts, and ignition support.
Help for worn cylinders, ignition problems, and related no-start conditions.
Remove broken keys from locks/ignition, then restore access and function.
Share your year + situation and we'll confirm compatibility and a typical price range. Or call the dispatch number directly.
