OBDSTAR X300 DP Plus Overview: Versions, Packages, and What's Included
The OBDSTAR X300 DP Plus is a tablet-based automotive diagnostic and key programming tool designed for professional use. It runs on an Android platform and connects to vehicles via a main diagnostic connector, with additional adapters available depending on the functions and vehicle types you need to cover. The device is built around a touchscreen interface, making it relatively straightforward to navigate compared to older handheld programmers with physical button menus.
One of the first things buyers notice is that the X300 DP Plus comes in different package configurations. The most commonly referenced are the A Package, B Package, and C Package, with the C Package often described as the most comprehensive option. Each package tier determines which vehicle brands, functions, and adapter sets are included out of the box. Before purchasing, it is essential to confirm exactly which package you are ordering, because the difference in coverage between tiers can be significant for your specific workflow.
The tool is designed to handle key programming, immobilizer functions, mileage correction, and a range of special service resets. It is not a basic code reader — it is positioned as a multi-function professional programmer. The tablet form factor means technicians can carry it around the workshop, use it at the vehicle, and review results on a reasonably sized screen without needing a laptop connection for most operations.
What is typically included in the box varies by package, but buyers should expect the main tablet unit, a diagnostic main cable, a power adapter, and potentially a set of key programming adapters. Always verify the exact box contents with the supplier before purchase, as bundle configurations can change. At GETOBDTOOL, we recommend confirming the adapter list with your supplier to ensure the tool arrives ready for the vehicle types you service most frequently.

Full Supported Car List: Makes, Models, and Function Coverage by Brand
The OBDSTAR X300 DP Plus car list is one of the broadest in its class, covering a wide range of Asian, European, and American vehicle brands. Coverage typically includes popular makes such as Toyota, Honda, Nissan, Hyundai, Kia, Ford, GM, Chrysler, BMW, Mercedes-Benz, Volkswagen, Audi, Renault, Peugeot, Citroën, and many more. However, the depth of function coverage varies significantly by brand and model year, which is an important distinction buyers often overlook.
For some brands, the X300 DP Plus may support full key programming including all-keys-lost scenarios, pin code reading, and remote programming. For others, coverage might be limited to specific model years or specific immobilizer systems. This is not a criticism of the tool — it reflects the reality of how immobilizer technology varies across manufacturers. The key takeaway is that you should always verify the specific function coverage for the vehicles you work on most, rather than assuming full coverage applies universally.
Official examples and videos include Mazda, Honda, Toyota/Lexus, Nissan, Hyundai and other Asian models, but exact coverage still depends on model year and function. European coverage is also present, though some advanced functions on newer European models may require additional tokens, software modules, or adapter cables. American domestic vehicles are included in the coverage list, with key programming and diagnostic functions available for major US brands across a range of model years.
Special functions beyond key programming also vary by brand. Mileage correction, for example, is supported for a range of vehicles but the specific models covered depend on the software version and package tier. Oil reset, EPB, TPMS, throttle reset, and other service functions are listed as supported for many brands, making the tool useful for general workshop maintenance tasks in addition to its primary programming role. We strongly recommend downloading or requesting the latest vehicle coverage list from your supplier before finalizing your purchase, as software updates can expand or adjust coverage over time.

C Package vs Full Version: Exact Differences and Which to Choose
The question of OBDSTAR X300 DP Plus C Package versus the Full Version is one of the most common points of confusion for buyers. Understanding the difference comes down to three things: which vehicle brands are activated, which special function modules are included, and whether additional adapter hardware is bundled in the package.
The C Package is generally positioned as the most complete single-purchase option, covering the broadest range of vehicle brands and functions available on the X300 DP Plus platform. The Full Version, depending on how a specific supplier defines it, may refer to the same C Package or may indicate a bundle that includes additional adapter kits such as the EEPROM adapter set or the Toyota smart key adapter. This naming can vary between resellers, which is why it is critical to ask your supplier for a detailed breakdown of exactly what software activations and hardware adapters are included before you pay.
For technicians who work across a wide variety of vehicle brands daily, the C Package or Full Version is almost always the better investment. The per-vehicle cost of the tool drops significantly when you are using it across dozens of different makes rather than just one or two. For shops that specialize in a single brand — say, exclusively Japanese imports — a lower-tier package might cover everything needed at a lower entry price.
Here are the key questions to ask your supplier when comparing package tiers:
- Which specific vehicle brands and model years are activated in each package?
- Are all-keys-lost functions included for the brands I work on most?
- What adapter hardware is physically included in the box?
- Are any functions token-based or require additional purchase after the initial buy?
- Does the package include a software update subscription, and for how long?
Getting clear answers to these questions before purchase will save you from discovering gaps in coverage after the tool arrives. A slightly higher upfront cost for the C Package or Full Version often makes more sense than buying a lower tier and then paying for individual upgrades later. If you are also evaluating competing platforms, our comparison of the Autel MaxiIM IM508S Full Review: Key Programming Deep Dive is a useful reference point for understanding how feature sets differ across professional key programmers.

Key Programming, Mileage Correction, and Special Functions Tested
The core strength of the OBDSTAR X300 DP Plus lies in its key programming capability. The tool is designed to handle immobilizer-related tasks including adding spare keys, replacing lost keys, and in supported cases, performing all-keys-lost procedures where no working key is available. The workflow typically involves reading the vehicle's immobilizer data, generating or cloning the key chip, and programming the new key to the vehicle's ECU.
For technicians new to key programming, the tablet interface guides you through the process step by step, which reduces the learning curve compared to older programmer tools that required memorizing menu sequences. That said, key programming is a technically demanding task, and results depend heavily on having the correct adapter for the vehicle's immobilizer system and ensuring the software version supports that specific model year. Always test on a vehicle you are familiar with before relying on the tool for a customer job.
Mileage correction is another headline function on this platform. The tool supports odometer adjustment for a range of vehicle makes and models, working through the OBD port or directly via the instrument cluster depending on the vehicle. As with key programming, coverage varies by brand and model year, and technicians should verify support for specific vehicles before committing to a job. Mileage correction tools are subject to legal regulations in many regions, so always ensure any use complies with local laws and is for legitimate purposes such as cluster replacement documentation. For a broader look at odometer-related tools, see our odometer correction tool collection.
Beyond programming functions, the X300 DP Plus includes a suite of special service functions that add everyday workshop value:
- Oil service reset — supported across a wide range of brands
- Electronic parking brake (EPB) service — useful for brake pad replacement workflows
- Throttle body adaptation — resets throttle position after cleaning or replacement
- TPMS reset and programming — depending on package and vehicle
- Battery registration — important for European vehicles with smart charging systems
- Steering angle sensor reset — required after alignment or suspension work
These service functions make the tool genuinely useful on a daily basis, not just for the occasional key programming job. A workshop that uses the X300 DP Plus for routine service resets alongside key programming will get significantly more value from the investment than one that only reaches for it when a key needs programming. For a broader overview of how professional diagnostic platforms compare across these service functions, the Car Vehicle Diagnostic Tool Scanner: Buyer's Guide & Comparison is a helpful reference.

Price Breakdown, Subscription Policy, and Where to Buy Safely
The OBDSTAR X300 DP Plus price varies depending on the package tier, the included adapter bundle, and the supplier you purchase from. Because this is a professional-grade tool with multiple configuration options, pricing is not fixed across all resellers. We recommend checking the current product page for the most accurate pricing, as costs can change based on promotions, bundle changes, or software update inclusions.
One of the most important cost considerations beyond the initial purchase price is the software update policy. OBDSTAR tools typically require an annual update subscription to access new vehicle coverage and software improvements after the initial free update period expires. The length of the included update period and the annual renewal cost should be confirmed with your supplier before purchase. A tool that looks affordable upfront but carries a high annual renewal fee may cost more over three years than a slightly more expensive tool with a lower or included update policy.
When evaluating the total cost of ownership, consider these factors:
- Initial purchase price including all adapters you need
- Length of included software update subscription
- Annual renewal cost after the free period ends
- Whether any functions require additional tokens or credits per use
- Warranty period and what it covers
- Supplier support quality — can you get help if a function does not work as expected?
Buying from a reputable supplier matters significantly for a tool like this. Key programming tools require reliable software support, and if you encounter a vehicle that should be covered but is not working correctly, having a responsive supplier who can escalate to the manufacturer is valuable. Be cautious of heavily discounted listings that do not include clear information about update policy, warranty, or adapter contents.
From our experience working with technicians, repair shops, and vehicle owners across our target markets, the buyers who are most satisfied with their X300 DP Plus purchase are those who took the time to verify coverage for their specific vehicle mix before buying, confirmed the update policy upfront, and purchased from a supplier with clear after-sales support. GETOBDTOOL lists this tool with A/B/C options, but current availability should be checked on the product page before ordering. and we can help you confirm which package and configuration suits your workshop before you commit.

Frequently Asked Questions
What is the difference between the OBDSTAR X300 DP Plus A, B, and C packages?
The main difference between the package tiers is the range of vehicle brands and functions that are activated in the software. The A Package covers a more limited set of brands, while the B and C packages progressively expand coverage to include more vehicle makes, additional special functions, and in some cases additional adapter hardware. The C Package is generally the most comprehensive option and is recommended for workshops that service a wide variety of vehicle brands. Always ask your supplier for a detailed breakdown of which brands and functions are included in each tier before purchasing, as the exact contents can vary between resellers.
Does the OBDSTAR X300 DP Plus support all-keys-lost programming?
All-keys-lost key programming is supported for a range of vehicle makes and models on the X300 DP Plus platform, but coverage is not universal across all vehicles. For some brands, all-keys-lost procedures require reading data directly from the immobilizer ECU or EEPROM chip, which may need additional adapter hardware beyond the standard OBD cable. Before taking on an all-keys-lost job for a specific vehicle, verify that the tool supports that exact make, model, and year by checking the coverage list or confirming with your supplier. This avoids situations where you have committed to a customer job only to discover the function is not supported for that particular vehicle.
How does the OBDSTAR X300 DP Plus software update policy work?
OBDSTAR tools typically include a period of free software updates from the date of activation, after which an annual subscription is required to continue receiving new vehicle coverage and software improvements. The exact length of the included free update period and the annual renewal cost should be confirmed with your supplier at the time of purchase, as these terms can vary. Keeping the software updated is important because new vehicle models and immobilizer systems are added over time, and an outdated software version may not support newer vehicles even if they fall within the tool's general coverage range. Factor the ongoing update cost into your total cost of ownership calculation.
Can the OBDSTAR X300 DP Plus be used for mileage correction legally?
Mileage correction functionality is included on the X300 DP Plus for supported vehicles, but the legality of using this function depends entirely on your local laws and the purpose of the adjustment. In many regions, adjusting a vehicle's odometer for fraudulent purposes is illegal and carries serious penalties. Legitimate use cases include documenting cluster replacement where the replacement unit shows a different mileage than the vehicle's actual history, or correcting errors caused by instrument cluster faults. Always ensure any mileage-related work complies with the laws in your jurisdiction and is properly documented. If you are unsure about the legal requirements in your area, consult a legal professional before using this function.
What vehicles does the OBDSTAR X300 DP Plus car list cover for key programming specifically?
The OBDSTAR X300 DP Plus car list for key programming covers a broad range of Asian, European, and American vehicle brands, with particularly strong coverage reported for Japanese and Korean makes. European brands including German manufacturers are also covered, though some advanced functions on newer models may require additional software modules or adapters. American domestic brands are included for key programming across a range of model years. Because vehicle coverage is updated regularly through software updates and the specific depth of function varies by model, we strongly recommend requesting the current detailed coverage list from your supplier and cross-referencing it against the specific vehicles you need to program before making your purchase decision.
