Dealing with a malfunctioning key fob for your 2008 Acura MDX can be a frustrating experience. Whether your key fob is broken, lost, or simply not working as it should, understanding your replacement options is crucial. This guide will walk you through the essentials of 2008 Acura Mdx Key Fob Replacement, helping you make informed decisions and get back on the road quickly.
One common issue Acura MDX owners face is with aftermarket key fobs. While they might seem like a budget-friendly solution, as low as $40, they can sometimes present challenges, particularly with reprogramming. Some users have reported that aftermarket cases might have a slightly different texture and lack the Acura logo, which are minor cosmetic differences. However, the real issue often lies in the functionality. Reprogramming an aftermarket fob can be tricky, and in some cases, it might be the transmitter itself that is causing the problem, not the programming process. This is highlighted by experiences where the original, albeit faulty, key fob still functions to some extent, suggesting the aftermarket transmitter might be the weaker link.
For reliable performance, especially when it comes to the electronic components of your key fob, opting for an Original Equipment Manufacturer (OEM) key fob is often the recommended path. While the initial cost might be higher, OEM fobs are designed specifically for your 2008 Acura MDX, ensuring compatibility and consistent performance. A practical approach can be to purchase an OEM fob and then transfer the physical key from your old fob to the new one. This can potentially save on the cost of key cutting, especially laser-cut keys which can be expensive.
A recurring physical issue with Acura MDX keys is related to how the key sits within the fob case. If your key appears to stick out slightly when the case is closed, this is generally inherent to the key hub mechanism itself, not a flaw in the case or spring. Unfortunately, there’s no simple fix for this. The only way to completely resolve this issue is to replace the entire metal key portion, which can be costly due to the cutting process, even though the keys themselves are relatively inexpensive.
Even if your old key fob is no longer fully functional, it might still have some utility. For instance, even with a broken unlock function, the “lock” button might still work. In such cases, the old fob can be kept as a dedicated locking device, useful for securing your vehicle, especially for nightly routines. However, features like the “open power gate” function might be linked to the unlock mechanism and won’t work if the vehicle is locked. The “panic” button might still function, but its practical value is limited for most users.
Another point to consider when disassembling your OEM key fob is the swing mechanism screws. Acura often uses blue Loctite on these screws to secure them. This can make disassembly challenging. There are reports of screws shearing in two or stripping out during attempts to unscrew them. Therefore, proceed with caution when working on these screws to avoid damaging the fob and ensure you have the necessary tools and patience.
When searching for aftermarket options, be aware that some key fobs are designed for SUVs with a liftgate, while others are for cars with a trunk. For the 2008 Acura MDX, ensure you are selecting the correct version, likely the SUV liftgate type. Acura IEM part numbers associated with these fobs include 35111-STX-329 and 35111-STX-326 for complete units, and 72147-STX-A12 and 72147-STX-A32 for transmitter-only replacements. These part numbers can be helpful when searching for compatible fobs online.
In conclusion, replacing your 2008 Acura MDX key fob requires careful consideration of your options. While aftermarket fobs offer initial cost savings, OEM fobs generally provide better reliability and compatibility. Be mindful of potential issues like reprogramming difficulties with aftermarket options and physical key issues inherent to the design. By understanding these factors, you can navigate the 2008 Acura MDX key fob replacement process effectively and choose the best solution for your needs.
