Replacing your 2010 Acura MDX key fob can seem daunting, but understanding your options and potential pitfalls can save you time and money. Many Acura MDX owners face issues with their key fobs over time, ranging from battery drain to button malfunctions or complete failure. This guide provides insights based on real-world experiences to help you navigate the replacement process effectively.
Aftermarket vs. OEM Key Fobs: Making the Right Choice
When it comes to replacing your 2010 Acura MDX key fob, you’ll encounter both aftermarket and Original Equipment Manufacturer (OEM) options. Aftermarket fobs, often available at lower prices, can be tempting. One user’s experience highlights the mixed bag of aftermarket solutions. While a generic aftermarket fob might look similar and even function to some extent, issues can arise during reprogramming. In some cases, these fobs may not program correctly, leading to frustration and wasted effort. The texture and lack of the Acura logo are minor cosmetic differences, but the potential for reprogramming problems is a significant drawback.

For reliable performance, especially with the sensitive electronics in modern vehicles like the 2010 Acura MDX, opting for an OEM key fob is generally recommended. While they may come at a higher initial cost, OEM fobs are designed specifically for your vehicle’s system, ensuring seamless programming and functionality. A practical approach to potentially save some money is to consider purchasing an OEM fob and transferring your existing physical key. This leverages the quality of the OEM transmitter while potentially reducing the cost associated with key cutting.
Addressing Common Key Fob Issues and Quirks
Beyond the choice between aftermarket and OEM, there are a few common issues and quirks to be aware of when dealing with your 2010 Acura MDX key fob. One reported issue is a key that slightly sticks out when the fob case is closed. This isn’t due to the case or spring, but rather an inherent characteristic of the key hub itself. Unfortunately, the only definitive fix for this is replacing the entire metal key portion, which can be an expensive undertaking due to the laser cutting required.
Another user’s experience sheds light on the interconnectedness of key fob functions. A broken “unlock” button on an older fob can impact seemingly unrelated features like the power tailgate. Specifically, the “open power gate” function may not work if the vehicle is locked, even if other buttons like “panic” still function. This highlights how different functions within the key fob system are linked.
Finally, a practical tip for those attempting DIY repairs or key swaps: be prepared for potentially stubborn screws. Acura often uses blue Loctite on the screws holding the swing mechanism of OEM keys. This can make disassembly challenging, and as one user discovered, screws can shear or strip if excessive force is applied. Patience and careful technique are crucial when dealing with these small components.
Key Fob Identification and Part Numbers
To ensure you order the correct replacement key fob for your 2010 Acura MDX, verifying the FCC ID and part number is essential. The FCC ID N5F0602A1A and part number N5F0602A1A are frequently associated with Acura key fobs of this era. These identifiers can often be found on the back of your existing key fob.
For those exploring aftermarket options or needing to specify the exact type of fob, Acura IEM part numbers are also relevant. Numbers like 35111-STX-329 and 35111-STX-326 differentiate between fobs with an SUV liftgate icon versus a car trunk icon. Transmitter-only part numbers such as 72147-STX-A12 and 72147-STX-A32 may also be useful when sourcing components.
Conclusion: Replacing Your 2010 Acura MDX Key Fob with Confidence
Replacing your 2010 Acura MDX key fob doesn’t have to be a headache. By understanding the pros and cons of aftermarket versus OEM options, being aware of common issues like key sticking and screw difficulties, and correctly identifying your key fob using FCC ID and part numbers, you can approach the replacement process with confidence. While aftermarket options exist, the experiences shared suggest that investing in an OEM key fob, or at least an OEM transmitter, is often the most reliable path to restoring full key fob functionality for your Acura MDX.
