Misplaced or lost your Infiniti key? Don’t worry—this guide will walk you through everything you need to know about Infiniti key replacement. Whether you’ve lost the key entirely, broken it in the ignition, or are simply locked out, we’ll explain your best options. From working with a dealership to calling a mobile locksmith, this step-by-step resource is designed to help you recover quickly, safely, and affordably.
Infiniti vehicles, particularly older models like the Infiniti Q45, J30, and first-generation G20, originally used traditional metal mechanical keys with no embedded chip or transponder. These keys typically used keyways such as DA24-P, DAT17R, and X237. They are simple cut-to-fit mechanical keys that operate the door and ignition without any electronic programming. While these types are no longer found in newer models, many older Infiniti cars still rely on this classic key design.
If you still drive an Infiniti that uses a traditional mechanical key, duplicating it is simple and affordable. One convenient option is ordering pre-cut keys online. By submitting your VIN, you can receive a replacement key cut to your specific car, often for as low as $25 to $40. Sites like Program Your Remote also offer remote programming instructions for related models.
Going through a dealership for a duplicate key is another option. Infiniti dealerships in Austin can typically provide a factory-original cut key if you bring proof of ownership. The cost at a dealer generally ranges between $65 to $120, depending on whether they have the key blank in stock. For a list of authorized dealers near you, visit our dealer locator page.
Alternatively, a mobile locksmith can often duplicate a traditional Infiniti key on-site. Mobile locksmiths usually charge $50 to $90 for a mechanical key copy and can complete the service at your home or workplace. This is particularly useful if your key is worn down or no longer functioning smoothly in the ignition.
If you have lost all copies of your key, the vehicle's VIN can still be used to create a new one. Whether you go to the dealer or a certified locksmith, they’ll typically need your VIN, driver’s license, and vehicle registration. Read more about how this works at our VIN key replacement guide. Expect a cost of $90 to $150 for full key creation using VIN data.
In some cases, if the ignition was replaced at any point, the original VIN key may not work. This can occur if a used or aftermarket ignition was installed. In such situations, decoding the current ignition or replacing it again may be necessary. Learn more about resolving this issue on our Ignition Repair & Replacement page.
Infiniti began using transponder keys in the late 1990s as part of their effort to enhance vehicle security. Models like the 1999 Infiniti I30 and later the QX4, G35, and M45 were among the early adopters of transponder technology. These keys contain a small chip that communicates with the vehicle’s immobilizer system. If the code doesn’t match, the engine will not start. Common transponder keyways and FCC IDs used in Infiniti vehicles include DA34 (X237), DA31, and FCC IDs like KBRASTU15 and NI04T.
If you need a duplicate transponder key, ordering a pre-cut key online is a convenient option. With your key code or VIN, online services can provide a ready-to-program key. Most pre-cut Infiniti transponder keys range from $45 to $85, not including programming. You can find compatible options and programming instructions at Program Your Remote, especially for models that allow onboard programming (typically older models).
Some Infiniti models allow for onboard programming of new keys if you already have two working ones. This self-service method avoids dealership or locksmith fees. However, many models—especially newer ones—require a professional scan tool to program the key into the vehicle’s ECU. If onboard programming is not possible, you will need to go through a locksmith or a dealer.
Infiniti dealerships in Austin can duplicate or replace transponder keys. You'll need your driver’s license and proof of ownership. Pricing at the dealer typically ranges from $120 to $220, depending on the model and whether the key blank and chip are available in stock. For assistance, visit our Infiniti Dealer Locator in Austin to connect with up to three nearby authorized service centers.
Licensed locksmiths equipped with advanced programming tools offer a faster, more affordable alternative. Mobile locksmiths can usually duplicate and program transponder keys for $90 to $160. This option avoids towing and can be scheduled at your home or office. Locksmiths also come in handy if the key is broken or if your only key was lost.
In the case of a complete key loss, you can still replace your transponder key using the vehicle’s VIN. The VIN allows either a dealer or a locksmith to cut a new key to factory specs and program it to your vehicle’s immobilizer system. Read more about the process in our VIN-based Key Replacement Guide. Prices typically range from $140 to $200, depending on the vehicle’s condition and programming method required.
If your ignition has been changed in the past—especially with a used or aftermarket cylinder—the VIN might no longer match the current ignition. This misalignment prevents key duplication using factory records. In this situation, a locksmith will need to manually decode the existing ignition or replace it again. Learn more on our Ignition Repair & Replacement page.
Infiniti began using proximity smart keys—often referred to as Intelligent Keys—in the early 2000s, starting with premium models like the Q45 and M45. By 2007, most Infiniti vehicles came standard with push-to-start ignition and keyless entry systems. These keys communicate wirelessly with the vehicle, allowing doors to unlock and engines to start without inserting a physical key.
Several FCC IDs are associated with Infiniti proximity smart keys. Common examples include:
You can duplicate Infiniti proximity keys by purchasing a pre-cut emergency blade and a new or used OEM fob online. The blade can be ordered based on your VIN, typically for $40 to $70. Programming the fob depends on the vehicle—some models support onboard programming, while others require scan tools. For detailed programming instructions, visit ProgramYourRemote.com. Full duplication with a remote usually costs around $100 to $180 when done through online sources. Learn more about this option at onlinecarkeycutting.html.
Infiniti dealerships such as Infiniti of Austin, Covert Infiniti, and South Austin Infiniti offer proximity key replacement and programming using OEM parts. This service typically costs between $280 and $450, and includes the emergency blade, new key fob, and full programming to your vehicle’s immobilizer system.
Automotive locksmiths are often more affordable than dealerships. A certified mobile locksmith can cut the emergency key and program a new or used fob on-site for approximately $180 to $300, depending on your vehicle’s model and year. Many locksmiths carry genuine OEM remotes, offering a balance between convenience and price.
If you’ve lost all your keys, a new key can be generated by VIN through either a locksmith or a dealership. Locksmiths generally charge between $200 and $280 for this service, while dealerships may charge $350 to $500. For more information, visit whatisvin.html.
It’s important to understand that push-to-start ignition repair or replacement is not a locksmith’s job. These systems involve electronic steering locks and ECU communication. If your ignition button or start system fails, you’ll need a qualified automotive electrician or dealer technician—not a locksmith. Electrical diagnostics and ECU syncing are outside the scope of standard key programming services.
Replacing a lost car key can feel overwhelming, but understanding the step-by-step process will help you get back on the road quickly and with minimal stress. Whether you’ve lost a transponder key, a proximity fob, or a traditional metal key, following these clear steps will ensure a smooth replacement experience.
Step 1: Confirm the Type of Key Lost
Before contacting anyone, identify what kind of key you lost. Was it a basic metal key, a chip-enabled transponder key, or a push-button start proximity key? Knowing this will help determine the replacement method and price. You can usually tell by whether your vehicle had remote locking/unlocking or required insertion into the ignition.
Step 2: Gather Required Information
Have your vehicle details ready. You’ll need the make, model, year, and Vehicle Identification Number (VIN). The VIN can often be found on the dashboard near the windshield or on your registration papers. This information allows a locksmith or dealer to generate or program a key that matches your car.
Step 3: Call a Locksmith or the Dealer
Next, decide if you want to work with an automotive locksmith or go through the dealership. Locksmiths are typically more affordable and faster, especially for roadside service. Dealerships are ideal if you prefer brand-new OEM keys and don't mind paying more or waiting a day or two. Read more about this choice at lostkeys.html.
Step 4: Test the New Key
Once the key is cut and programmed, test it thoroughly. Ensure it unlocks the door, starts the engine, and communicates with the immobilizer. For proximity fobs, check that the push-button start works and that remote functions like lock, unlock, and trunk release are functioning correctly.
Step 5: Make a Spare Key
After your replacement key is working, don't stop there. It's always wise to make a duplicate car key immediately. Losing your only key again can cost you even more, especially if reprogramming or ECU syncing is needed. Most locksmiths can duplicate a second key on-site for less than the cost of a full replacement.
By following this step-by-step lost key replacement process, you’ll avoid unnecessary delays and expenses. Preparation and prompt action are key to turning a frustrating situation into a quick solution.
If you're having trouble with your Infiniti’s ignition, you’re not alone. Ignition issues are common in both older and newer Infiniti models, and they can stem from a variety of problems including worn components, attempted theft, or key damage. Understanding what causes these problems—and how to fix them—can save you time and stress. Here’s what to know about Infiniti ignition repair and replacement.
Broken Key in Ignition
One of the most frequent ignition issues is a key that snaps off inside the ignition cylinder. This can happen due to metal fatigue, a bent key, or excessive force. Attempting to remove the broken piece on your own could cause more damage. A professional ignition locksmith can extract the broken key without harming the ignition housing. In some cases, a full ignition cylinder replacement may be recommended. Visit ignitionlocksmith.html to learn more about how this service works.
Key Stuck in Ignition
If your key is stuck and won’t come out, the issue may be mechanical or electronic. Problems like a damaged shift interlock system, worn wafers inside the cylinder, or a faulty ignition lock mechanism can all cause this. An experienced locksmith can diagnose the exact problem, disassemble the ignition if needed, and repair or replace it on-site—usually within an hour.
Key Won’t Turn in Ignition
When a key won’t turn in the ignition, it could be due to a worn key, a faulty cylinder, or a steering lock issue. Before forcing the key, try gently moving the steering wheel while turning the key. If that doesn’t work, a locksmith can inspect both the key and the ignition cylinder to determine if rekeying or full replacement is necessary. In some Infiniti models, the immobilizer system may also require syncing with the new ignition components.
Burglary Repair and Ignition Replacement
After an attempted vehicle theft or burglary, it’s common for the ignition switch to be damaged or completely destroyed. In these cases, replacing the ignition switch is not optional—it’s essential. A mobile locksmith can remove the damaged parts, install a new ignition cylinder, and match it to a new key. Some services also offer cosmetic repair for steering columns or ignition bezels affected during the break-in. For complete support, check out ignitionlocksmith.html.
Whether your issue is a stuck key, broken ignition, or theft damage, Infiniti ignition repair and replacement is best handled by a skilled professional. Don’t wait until the vehicle becomes completely inoperable—addressing the problem early ensures your car stays secure and reliable.
When replacing your car key, you’ll need to choose between a dealership and a local locksmith or mobile service. Dealerships provide OEM keys and guarantee factory programming, but they often require towing the vehicle and charge higher rates. In contrast, mobile locksmiths offer faster service at your location and may use either OEM or high-quality aftermarket keys. While dealerships are ideal for brand-new vehicles or warranty work, locksmiths are more affordable and convenient for urgent needs. For most drivers, mobile service is a practical solution—especially when towing to the dealer could cost an additional $100 or more.

1. What should I do if I lose my Infiniti key while away from home?
If you lose your Infiniti key while out and about, contact a mobile locksmith that provides roadside assistance. They can come directly to your location and generate a working replacement key on-site, even if you've lost all existing keys.
2. Can I get a new Infiniti key without the original?
Yes, a professional locksmith can replace your Infiniti key without needing the original. Using your vehicle identification number (VIN), they can cut and program a new key that works with your car’s security system, including the transponder and immobilizer.
3. Will a locksmith be able to open my trunk if my key is lost?
Absolutely. Trunk access is typically included in full vehicle unlocking services. Even with lost keys, a locksmith can gain entry to both the doors and the trunk using specialized tools and techniques without causing damage to your Infiniti.
4. Are Infiniti keys equipped with a transponder chip?
Most modern Infiniti keys, including standard and proximity styles, are equipped with a transponder chip. This chip communicates with your vehicle’s computer to enable ignition. Without proper transponder programming, the key will not start the engine.
5. Can roadside assistance help with Infiniti key replacement?
While basic roadside assistance services may offer lockout support, they typically do not provide full key replacement or programming. For that, you’ll need a certified automotive locksmith who can both cut the key and program it to your vehicle.
6. Can I get a spare Infiniti key made even if I still have one working key?
Yes, and it’s highly recommended. A locksmith can duplicate your working Infiniti key to create a backup. Whether it’s a transponder key or smart key, having a spare can prevent the inconvenience and expense of emergency replacement later on.
7. Does my insurance policy cover lost Infiniti keys?
Some comprehensive auto insurance policies include key replacement as part of theft or loss coverage. It’s best to review your policy or speak with your insurance provider to determine if you’re eligible for reimbursement after replacing a lost or stolen key.
8. How long does it take to replace a lost Infiniti key?
Most mobile locksmiths can complete the job in 30 to 60 minutes, depending on the key type and model year. This includes key cutting, transponder programming, and testing all functions, including door, ignition, and trunk access.
9. Can I use an aftermarket key or fob with my Infiniti?
Yes, many locksmiths can program high-quality aftermarket keys or remotes that function just like OEM parts. These aftermarket options are often more affordable, but make sure the key is compatible with your vehicle’s transponder and immobilizer system.
10. Do locksmiths need to reprogram my car if the ignition was changed?
If your ignition was replaced, the key code may no longer match your car's ECU. A locksmith can reprogram the transponder chip to sync with the new ignition. In some cases, this may involve accessing your vehicle’s onboard computer for calibration.
