Experiencing issues with your 2020 Acura Mdx Key Fob can be frustrating. From malfunctioning buttons to difficulties in reprogramming, many owners encounter similar problems. This guide addresses common concerns and offers advice for troubleshooting and replacing your key fob.
Common Problems with 2020 Acura MDX Key Fobs
Several issues can arise with your 2020 Acura MDX key fob. One frequent problem is button failure. Over time, buttons for locking, unlocking, or opening the tailgate can become unresponsive due to wear and tear. Some owners also find that the physical key blade, which folds into the fob, can become loose or stick out slightly when closed. This issue is often related to the key hub mechanism itself, rather than the key fob case.
Another challenge arises when considering aftermarket key fobs as replacements. While they can be a more budget-friendly option, reprogramming them to work with your 2020 Acura MDX can sometimes be problematic. Compatibility issues with the transmitter in aftermarket fobs may lead to unsuccessful reprogramming, even when following standard procedures. It’s also worth noting that accessing the internal components of your key fob for repairs, like replacing the swing mechanism, can be tricky. Screws are often secured with threadlocker, making disassembly difficult and potentially leading to stripped screws or damage.
Solutions and Replacement Options
When facing key fob issues, you have several options. For button problems or a damaged case, you might consider replacing just the key fob case or attempting DIY repairs if you are comfortable with electronics. Numerous online resources, such as YouTube videos, offer helpful guides for disassembling and repairing key fobs. However, for reprogramming or transmitter issues, especially with aftermarket fobs, the solution might be more complex.
While aftermarket fobs are available and often cheaper, some users report better success with Original Equipment Manufacturer (OEM) fobs for guaranteed compatibility and easier programming. If you opt for an aftermarket fob, ensure it is specifically designed for your 2020 Acura MDX and check the FCC ID and part numbers for compatibility, such as N5F0602A1A. Be aware that aftermarket cases might have slight cosmetic differences, like texture or the absence of the Acura logo.
When considering replacement, you might encounter different key fob designs, particularly concerning the tailgate button icon. Some fobs feature an SUV liftgate icon, while others show a car trunk icon. These variations may correspond to different Acura Internal Equipment Manufacturer (IEM) part numbers, such as 35111-STX-329 or 35111-STX-326. For transmitter-only replacements, part numbers like 72147-STX-A12 or 72147-STX-A32 might be relevant.
If your physical key blade is damaged or sticking, replacing just the key portion can be cost-effective. However, laser-cut keys require professional cutting, which can add to the overall expense. Consider transferring your existing, cut key blade to a new OEM fob to save on key cutting costs if the blade is still in good condition.
Conclusion
Dealing with a faulty 2020 Acura MDX key fob can be a minor inconvenience or a major headache. By understanding common issues and exploring your replacement and repair options, you can find the best solution for your needs. Whether you choose to repair your existing fob, opt for an aftermarket replacement, or invest in an OEM key fob, being informed will help you make the right decision and regain full functionality of your keyless entry system.
