Car key replacement
Replace a lost or damaged key for the G20 sedan, including cutting and (when needed) programming.
Low Rate Locksmith provides Infiniti G20, a compact sedan, key replacement and mobile locksmith service across the USA and Canada. If you lost every key, need a tested spare, or your remote stopped working, we focus on the correct key system for your G20 sedan and document the work before we close out the job.
| Question | Answer |
|---|---|
| Typical cost | Typical Cost Range: $120-$550 (industry-typical; exact price confirmed at dispatch). Your total depends on year/system, whether all keys are lost, parts choice, and any programming needed. Prices shown are $USD; Canadian customers pay the equivalent in CAD. |
| Programming required? | Sometimes. Many G20 sedan keys are simple metal keys, while later systems may use a transponder key and/or a keyless-entry remote that needs pairing. |
| All keys lost? | Often yes, after photo ID and proof of ownership are confirmed. For transponder-equipped G20 sedan setups, the immobilizer must recognize the new key before the engine will start. |
| Online fob accepted? | Sometimes, but compatibility has to match the vehicle’s system and frequency. Used or locked fobs are a common reason customer-supplied parts fail. |
| What to prepare | Vehicle year, your location, a working key (if you have one), photo ID, and proof of ownership/authorization. |
Replace a lost or damaged key for the G20 sedan, including cutting and (when needed) programming.
Pair transponder keys and many remotes to the vehicle so the security system recognizes them.
Help with non-working buttons, intermittent range, or re-sync needs on keyless entry remotes.
Diagnose key-won’t-turn issues and ignition cylinder wear that can mimic a key problem.
Remove a snapped key blade and cut a replacement when the cylinder condition allows.
Non-destructive entry when you’re locked out of the G20 sedan, then route you into a spare if needed.

The Infiniti G20 sedan was produced across a span where some vehicles used a metal key only, while others use a transponder key (a chip inside the key head) and a separate keyless-entry remote. Infiniti vehicles commonly share Nissan security architecture such as NATS on many platforms, but the exact G20 sedan key system is identified from the vehicle during service so we cut and program the correct type.
If you’re in Canada and your G20 sedan is a Canadian-market vehicle, key and remote variants can differ from USA-market versions. We account for those differences during compatibility checks.
The metal profile that physically operates door, trunk, and ignition cylinders.
When equipped, the chip must be recognized by the immobilizer before the engine will start.
A wear point that can cause “key won’t turn” symptoms even with a correctly cut key.
Pin tumbler cylinders that can be rekeyed or repaired when damaged or mismatched.
Electronic components that move locks; failures can look like a remote problem.
Mechanical steering lock interaction can add resistance that feels like a bad key.
| Option | Best for | Watch out for |
|---|---|---|
| Infiniti 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 situations or every G20 sedan system |
Aftermarket keys and remotes can work when the part number, frequency, and board match the vehicle’s system. The risk is paying twice if the part cannot be enrolled or if it’s previously locked to another car.
If buttons stopped working, a remote battery is the first check. If the G20 sedan also has starting or security indicator symptoms, we treat it as a vehicle-side recognition problem until testing proves otherwise.
Infiniti used more than one key setup during the G20 sedan’s production years. We identify the exact system from the vehicle before cutting or programming parts.
| Years (context) | Key system (typical) | Notes |
|---|---|---|
| 1991 to early production years | Mechanical metal key (no chip) | Cut-to-code or cut-from-existing. No immobilizer enrollment when the vehicle is mechanical-only. |
| Mid to late production years (varies by trim/market) | Transponder key + keyless-entry remote | The engine will not start unless the immobilizer recognizes the transponder. Remote pairing is separate from key cutting. |
For the G20 sedan, price depends on whether the vehicle is metal-key only or uses a transponder/remote system, and whether you still have a working key. A spare made from an existing working key is usually simpler than originating a key when all keys are lost.
Typical Cost Range: $120-$550 (industry-typical; exact price confirmed at dispatch). Prices shown are in $USD; Canadian customers pay the equivalent amount in CAD. Dealer quotes and mobile quotes can differ based on parts availability, programming method, and whether the vehicle must be towed.
| Factor | Cost impact |
|---|---|
| Spare key with one working key | Usually lower |
| All keys lost | Usually higher |
| Customer-supplied fob | Depends on compatibility |
| Emergency timing or remote location | May affect service call cost |
| Vehicle-side issue (battery, ignition) | May require diagnosis before key work |
Final pricing is confirmed after the vehicle year, key type, location, authorization, and compatibility are reviewed.
For the G20 sedan, we identify whether it’s metal-key only or transponder-equipped, then cut (and program when required) a working key after authorization is confirmed.
Often points to transponder recognition, a worn key, or an ignition/anti-theft condition; we test to separate key issues from vehicle-side faults.
Remote lock/unlock can work even when the immobilizer will not accept the key; we confirm whether the key has the correct chip and enrollment.
Most G20 sedans are turn-key; if you’re seeing a no-start condition, it’s usually not a proximity issue and needs key/immobilizer or ignition diagnosis.
If you bought a key or remote online, we can check whether it matches the vehicle’s system before attempting cutting or pairing.
If you can’t provide ID and proof of ownership/authorization, we do not cut or program keys.
We confirm the vehicle details on-site and review ID plus ownership/authorization before work begins.
We determine whether your G20 sedan uses a metal key only, a transponder key, and/or a programmable remote.
We cut the key and perform programming/pairing when the vehicle requires it for starting or remote functions.
We test functions we serviced (start/locks/remote as applicable) and document results before payment closeout.
| Stage | Deliverable | Format |
|---|---|---|
| Vehicle ID | Vehicle details captured for correct key system matching | On-site notes |
| Authorization | ID and ownership/authorization check completed | Documented confirmation |
| Cutting | Key cut to match the vehicle (when applicable) | Physical key |
| Programming | Transponder/remote pairing performed when required | On-site procedure record |
| Verification | Function tests for serviced items (start/locks/remote as applicable) | Demonstrated results |
| Closeout | Final scope and price confirmed before payment closeout | Invoice/receipt |
We align on the problem (lost keys, spare, remote, ignition symptom) and the key system before cutting or programming.
ID and proof of ownership/authorization come first. If authorization is not present, we stop.
We match the key/remote to the vehicle’s system to reduce the risk of wasted parts and repeat labor.
We test the functions we serviced (as conditions allow) and confirm results with you before closing the job.
Most G20 sedan key work can be performed where the vehicle sits, avoiding towing in many situations.
Automotive locksmith work is different from door-hardware work. Our workflow is built around vehicle security systems and lock cylinders.
When the vehicle supports it, we can discuss OEM-equivalent vs aftermarket options and the trade-offs.
We provide clear documentation of what was done so you can reference it later if you add spares.
We dispatch mobile automotive locksmith support throughout the USA and Canada, with service availability varying by location.
If you still have one working key for the G20 sedan, duplicating is often less involved than originating a key after total loss.
The G20 sedan is typically turn-key, but remote and transponder differences still matter. Knowing your exact setup helps reduce mismatched parts.
If you buy parts online, match the system details first. Used remotes are frequently locked or the wrong frequency for USA vs Canada variants.
Clear access to the driver door and ignition area helps reduce service time, especially when programming is required.
Low 12V voltage can interrupt programming or create false no-start symptoms. If the car battery is weak, address that first.
When you’re not locked out or stranded, scheduling can reduce added dispatch variables. This applies in both the USA and Canada.
Share your year + situation and we'll confirm compatibility and a typical price range. Or call the dispatch number directly.
