Losing your Infiniti key can feel overwhelming, especially during a busy day or late-night emergency. This quick guide will walk you through exactly what to do if you've lost your Infiniti keys, including how to identify your key type, gather the right info, and choose the best option for replacement. Whether you need a transponder key, remote fob, or smart key duplicated, we’ll help you get back on the road fast.
Infiniti vehicles, particularly the earlier models, often used traditional metal keys without embedded chips. These mechanical keys are simple, durable, and easy to duplicate. Some common mechanical keyways used by Infiniti include the X237 and DA34. Older Infiniti models such as the 1990 Infiniti Q45 and early '90s G20 featured these non-transponder mechanical keyways. These keys operate only the mechanical lock cylinder and do not require programming, making them cost-effective and straightforward to replace.
If you already have a working key, duplicating it online is one of the easiest and cheapest options. You can order a pre-cut key online by submitting a clear photo of your original key or entering the key code. Visit our online key cutting guide or refer to external services like programyourremote.com for detailed instructions and pricing. Online duplication for mechanical Infiniti keys typically ranges from $15 to $40 depending on the key type and shipping method.
Another option is to visit your local Infiniti dealer. With your VIN and proof of ownership, the dealer can provide you with a factory-spec mechanical key. However, dealer services usually involve higher costs and may include towing the vehicle if you’re locked out. Visit our dealer locator page to find a nearby Infiniti dealership.
Locksmiths remain a reliable and affordable option for duplicating or replacing traditional metal keys. A mobile locksmith can cut a new key on-site, saving you the hassle of towing or waiting days for shipping. Most locksmiths charge around $50 to $80 for cutting and testing a standard mechanical Infiniti key.
If you’ve lost all copies of your key, you can replace it by VIN. Dealers and certified locksmiths can access key code databases using your vehicle identification number and proper ID. For step-by-step instructions, see our guide at what is VIN.
Keep in mind, if your ignition was replaced at some point and no longer matches the VIN, the new key won’t turn the lock. In such cases, a locksmith must decode the current cylinder manually or replace it. Visit our ignition repair page for more help in diagnosing this issue and getting the correct key solution.
Infiniti began using transponder keys in the late 1990s to enhance vehicle security through immobilizer systems that require a chip signal from the key to start the engine. These keys are visually similar to traditional metal keys but contain an embedded chip programmed to the vehicle’s electronic control unit (ECU). Non-laser cut transponder keys were standard on models such as the 1999-2002 Infiniti G20, 2000-2004 I30/I35, and the 2002-2006 QX4. Keyways like DA34 and DAT17 were commonly used, paired with FCC IDs such as KBRASTU15 and CWTWB1U751, both of which are verified transponder key types for various Infiniti models.
If you need a duplicate key and still have a working transponder key, you can use online services that offer pre-cut duplication. By submitting your key code or a high-resolution photo of the key blade, you can order a blank transponder key cut to your vehicle. The chip still requires programming either by onboard programming (if supported) or by a locksmith. Online services like our cutting guide and platforms like Program Your Remote provide instructions and pricing. Expect to pay around $40 to $80 for cutting and another $60 to $100 for chip programming, depending on your model and programming method.
If you prefer to go through a dealership, Infiniti dealers can cut and program a new key using your VIN and proof of ownership. Dealer prices tend to be higher, often ranging from $150 to $250 for non-laser transponder key replacement. Use our dealer locator to find an authorized Infiniti dealership in your area.
A mobile automotive locksmith is often the fastest and most cost-effective route for both duplication and full key replacement. Locksmiths carry advanced diagnostic and programming tools that allow them to cut and program keys on-site. Pricing typically ranges from $120 to $180 depending on key type, vehicle year, and availability. This includes both cutting and chip programming.
If all your keys are lost, a replacement key can be created using your vehicle’s VIN. Both dealerships and many locksmiths can access Infiniti’s key code database to retrieve the correct cut and chip information. Visit our VIN guide to learn how to prepare for a VIN-based replacement.
It’s important to note that if your vehicle’s ignition lock was changed previously and no longer matches the original VIN data, the replacement key won’t work. In this case, a locksmith must physically decode the ignition cylinder to determine the correct key cut or replace the cylinder entirely. Learn more about this process on our ignition repair page.
Infiniti began using proximity key technology in the mid-2000s with luxury models like the M35, FX35, and G37. These smart keys allow for keyless entry and push-to-start ignition, enhancing both convenience and security. Unlike traditional keys, proximity keys operate by wireless communication with the vehicle's onboard system.
Some verified FCC IDs for Infiniti smart keys include:
Owners can duplicate Infiniti proximity keys in several ways. One convenient method is ordering a pre-cut key online using VIN-based cutting. This option is ideal for those who already have the original key or its key code. Onboard programming is often not available for smart keys, so professional programming will be needed. Expect to pay $90–$180 for pre-cut blanks online. For reference and cutting services, visit onlinecarkeycutting.html and https://www.programyourremote.com.
Going to a dealership for duplication is another route. Dealers usually charge more for smart key duplication, typically $250–$500, depending on the model and year. They may also charge for labor and require an appointment. For local dealership options near you, visit findadealer.html.
Locksmiths can often duplicate Infiniti proximity keys for a lower rate than dealers. They carry OEM or aftermarket smart keys and offer mobile programming. Prices vary by location and complexity but often range from $180–$320.
If you've lost all keys, a locksmith or dealer can cut and program a new smart key using the vehicle’s VIN. This may require proof of ownership and ID. Learn more at whatisvin.html.
In cases where the ignition was previously replaced or rekeyed, the VIN may no longer match the mechanical lock. This situation requires decoding or replacing the ignition, often addressed by a specialist. More information is available at ignitionlocksmith.html.
Lastly, proximity key systems rely on complex wiring and modules. If the push-to-start button malfunctions or the key is not being detected, the issue may be electrical. In such cases, diagnosis and repair should be handled by an automotive electrician, not a locksmith.
Replacing your lost Infiniti key doesn’t have to be stressful when you follow the right steps. Here’s how to handle it quickly and professionally:
Confirm the Type of Key Lost: Identify whether your lost key was a traditional metal key, a Transponder, a laser-cut key, or a smart proximity key. Knowing the key type helps determine duplication or replacement options.
Gather Required Information: You'll need the vehicle’s VIN (Vehicle Identification Number), year, make, model, and proof of ownership (such as title or registration). These details are necessary whether you choose a locksmith or dealership.
Call a Locksmith or the Dealer: For fast help, a mobile car locksmith is your best bet. They offer roadside assistance, same-day service, and in many cases, more affordable rates than a dealer. If you opt for the dealership, towing may be required. Learn more at automotivelocksmith.html.
Test the Key: After programming, test the new key for lock/unlock functions and ignition start. For Transponder keys, ensure the car recognizes the chip correctly. Learn more about chips at transponderkey.html.
Make a Spare Key: Avoid future emergencies by duplicating your new key. Whether it’s a traditional or smart key, duplication is easier and cheaper once a working key is available. Check duplicatecarkeys.html for details.
