Experiencing problems with your 2007 Acura MDX key fob? You’re not alone. Many owners encounter similar frustrations, ranging from reprogramming difficulties to physical malfunctions. Based on real-world experiences, this guide dives into common issues and potential fixes for your 2007 Mdx Key Fob.
One owner recounted their recent experience attempting to resolve their key fob issues. Initially, they followed online advice, specifically a helpful YouTube video from AccuraAddicted, and purchased an aftermarket fob for around $40. While the aftermarket case was deemed “pretty good,” with only minor texture differences and lacking the Acura symbol, reprogramming proved to be a hurdle. This led to the suspicion that the aftermarket transmitter itself might be the problem, especially since the original, albeit malfunctioning, fob was still partially operational.
Considering these reprogramming challenges, and drawing from extensive experience replacing keys and fobs across various vehicles, the owner leaned towards Bogdan’s recommendation to opt for an OEM (Original Equipment Manufacturer) fob. The strategy then shifted to using the new OEM transmitter while transferring the existing, and presumably correctly cut, key. This approach aims to bypass potential issues with aftermarket transmitters and the cost of laser key cutting. It’s important to note that if your key appears to stick out slightly when the fob case is closed, this is often due to the key hub itself, not the case or spring mechanism. Unfortunately, the only definitive fix for this mechanical issue is replacing the entire metal key portion, which can be expensive due to the laser cutting involved. Simply replacing the key blank might not resolve this inherent issue.
The owner also shared an intention to repurpose their old, broken fob—initially hoping to use it solely for unlocking and locking functions. However, the broken unlock button presented a limitation: the “open power gate” feature wouldn’t function when the vehicle was locked, only when unlocked. While the “panic” button still worked, it was deemed largely unnecessary. Despite its flaws, the old fob still serves a purpose for a nightly “lock” check of multiple vehicles, as the lock function remained operational.
A further complication arose when attempting to disassemble the OEM key. The screws securing the swing mechanism were found to be secured with blue Loctite. This resulted in one screw shearing in half during removal and another stripping out entirely. Resolving these damaged screws required extra effort to restore functionality to the key mechanism.
When exploring aftermarket options for a 2007 Acura MDX key fob, it’s crucial to pay attention to icon variations. Some aftermarket fobs display an SUV liftgate icon, while others show a car trunk icon. These icons are believed to correspond to Acura IEM part numbers 35111-STX-329 and 35111-STX-326. For those only needing the transmitter, the relevant part numbers are 72147-STX-A12 and 72147-STX-A32.
In conclusion, addressing 2007 Acura MDX key fob issues can involve navigating reprogramming challenges, mechanical key problems, and even stubborn screws. While aftermarket fobs offer a cost-effective alternative, OEM parts may provide a more reliable solution, particularly regarding transmitter functionality and avoiding reprogramming headaches. Carefully consider these factors and part numbers when seeking a replacement or repair for your 2007 MDX key fob.
