Hello fellow Volvo enthusiasts! As a content creator at keyfobx.com and a dedicated auto repair expert, I understand the importance of having reliable key fobs for your Volvo. Recently, I’ve been diving deep into Volvo Key Fob Programming for our projects, and I’ve gathered a wealth of knowledge that I’m excited to share with you. This guide is designed to be your ultimate resource for understanding Volvo key fobs, programming them yourself using VIDA, and exploring cost-effective options like using second-hand keys. Forget expensive dealership quotes – let’s explore how you can manage your Volvo keys efficiently.
Understanding Volvo Key Fobs for SPA/CMA Platforms
For Volvo models built on the SPA (Scalable Product Architecture) and CMA (Compact Modular Architecture) platforms, managing your key fobs is more straightforward than you might think. Here are some crucial points to keep in mind:
- Universal Compatibility: Whether you opt for a brand-new key fob or a used one, any compatible Volvo key fob can be programmed to your vehicle. There’s no need for any “virginizing” process with Volvo key fobs, which simplifies things significantly. Just place the key in the cupholder, and VIDA (Volvo Diagnostic tool) will guide you through the pairing process.
- DIY Programming with VIDA: The programming, or “adding a key fob,” function is readily available in VIDA under the “keyless appl” section. If you have access to VIDA, you can handle this process yourself, saving on dealership costs. Of course, Volvo dealerships can also perform this service if you prefer professional assistance.
- Dealer Flexibility: While some dealerships might express reservations about programming customer-supplied or used keys due to internal policies, it’s important to understand that technically, there’s nothing preventing them from using VIDA to program any compatible key fob.
- Frequency Matters: Volvo key fobs come in different frequency variations, primarily 434MHz, 315MHz, and a 434MHz “narrow band” version (specific to South Korea). In North America, 434MHz keys are standard. While this guide focuses on the 434MHz keys common in North America, the general principles should be broadly applicable to other markets.
- Key Variations, Not Part Numbers: We’ll delve into the different types of key fobs available, but we won’t be bogged down by Volvo part numbers. The sheer number of part variations makes tracking them all impractical. Our focus is on understanding compatibility and the practicality of using recycled keys.
- Keyless Operation Systems: Your Volvo might have “keyless starting” or the more comprehensive “keyless locking and unlocking (Passive Entry)” system. However, in North America, passive entry is generally standard on SPA/CMA platform cars. Regardless of the specific system, the key fobs and programming procedures remain the same.
- Emergency Blade Key: We won’t go deep into the physical emergency blade within the key fob, but it’s worth noting that dealerships or Volvo-registered locksmiths can cut a new blade for you. Alternatively, blanks are available in the aftermarket if you need to copy an existing blade.
Considering adding or replacing a key fob with a used one? The used market, particularly platforms like eBay, offers reasonably priced options. A new battery, and a used key fob can function just like a new one. I myself have programmed several used fobs to my Volvo – perhaps more than strictly necessary!

Let’s dive into the specifics of key variations to help you choose the right fob for your Volvo.
Key Variations: Motion Sensing (MS) Technology
Around 2021, Volvo introduced “Motion Sensing” (MS) key fobs in their new vehicles. This upgrade was specifically designed to enhance security and protect against “relay attack” thefts, a vulnerability associated with proximity key fob systems. Motion sensing keys are engineered to deactivate when they remain stationary for a period, thus preventing unauthorized relay and car theft.
Volvo also offers an upgrade kit for pre-2021 models, allowing owners to switch to these advanced MS keys. This kit includes a set of brand new replacement key fobs, reflecting Volvo’s commitment to security enhancements across their range.
Identifying motion sensing keys is straightforward by checking the manufacturer’s (Huf) model number. The non-MS key is model HUF8423, while the motion sensing version is HUF8423MS. Similarly, the FCCIDs, often used in online listings for used keys, are YGOHUF8423 for non-MS and YGOHUF8423MS for MS keys. These model and regulatory numbers are typically printed inside the key fob, under the area where the emergency blade sits. For the sport key tag variants, the model numbers are HUF8432/HUF8432MS, and the FCCIDs are YGOHUF8432/YGOHUF8432MS. Note that these part numbers specifically refer to the 434MHz frequency keys.
Importantly, both MS and non-MS keys are fully interchangeable and programmable on compatible Volvo models. The motion sensing functionality is self-contained within the key fob itself, meaning the car’s system doesn’t differentiate in terms of programming.

Key Styles and Shell Customization
Volvo offers a variety of key styles and shells, and it appears the aesthetic and material quality has evolved over the years. For example, my 2019 S60 came with two luxurious leather-shell key fobs, color-matched to the interior, along with a buttonless, waterproof sport key tag. In contrast, newer Volvos often come with two plastic-shell key fobs as standard.
Volvo also provides accessory replacement key shells in various colors and premium finishes like woodgrain, allowing for personalization. The great news is that all these shells are universally compatible with all fob internals. You can freely mix and match shells to suit your preference. I upgraded my own used MS keys by swapping the original plastic shells for my original leather ones. I even found a beautiful amber leather shell on eBay, ensuring my wife’s key is easily distinguishable – a practical solution after a nine-month key-misplacement saga involving her Mazda!
One minor aesthetic detail: some plastic shell keys come with black buttons. If you swap a shell from a “silver button” key, you’ll notice a subtle change in appearance, but the key’s functionality remains unaffected.

Regarding the sport key tag, battery replacement is technically possible but not designed to be user-serviceable. Therefore, consider this when purchasing used sport key tags. I personally experienced an upgrade journey with the sport key tag when I bought a new MS version, only to discover that the one replaced under warranty was already an MS type. Now, I’m fortunate to have two MS sport key tags in my collection.
Special Volvo Keys: Restricted Key and Care Key
Volvo has also introduced two specialized key types for enhanced control and safety:
- Restricted Key (Red Key): This key enables vehicle operation with several limitations, including speed and stereo volume limits, and it prevents the deactivation of certain safety features. Ideal for situations where you want to lend your car but maintain control over its usage.
- Care Key (Orange Key): The Care Key is designed with safety in mind, allowing you to set a maximum speed limit for the vehicle. If no speed limit is set, it functions as a normal key. This is particularly useful for young or less experienced drivers.

The functionality of Restricted and Care Keys is determined by the vehicle’s factory configuration. However, Volvo offers a service software that dealers can use to disable the restricted key function on vehicles originally delivered with a red key, upon the owner’s request. Here’s how these special keys behave when programmed to your Volvo:
- Vehicles without Factory Restricted/Care Key (or with Disabled Restricted Key): Any red or orange key programmed to such a vehicle will function as a standard, unrestricted key.
- Vehicles Delivered with Restricted Key: If your car was originally equipped with the restricted key feature, any red or orange key programmed will operate as a Restricted Key, regardless of whether it was originally a Care Key or Restricted Key.
- Vehicles Delivered with Care Key: Similarly, if your vehicle came with the Care Key feature, any red or orange key programmed will function as a Care Key.
A Few Final Points to Remember:
- When swapping shells, the shell release slider on the fob retains the original shell color (orange or red for special keys), helping you keep track of your Restricted and Care Keys even after shell changes.
- Motion sensing versions exist for Red Keys, and it’s likely that newer Care Keys are all MS versions for enhanced security.
- Polestar Compatibility: All information above applies equally to Polestar vehicles. While Polestar might not have offered special keys, the Volvo keys are compatible – they are essentially the same keys with different shells.
Hopefully, this guide serves as a valuable resource as your Volvo ages and key fobs may need replacing due to damage or loss. Considering the high costs often quoted by dealerships for new programmed keys, understanding your DIY options and the viability of using used keys can be incredibly beneficial.
