Experiencing issues with your 2017 Gmc Key Fob can be incredibly frustrating, especially when it starts acting erratically. For owners of the 2017 GMC Silverado and similar models, a peculiar problem has surfaced involving the key fob causing doors to randomly unlock. This article delves into a firsthand account of troubleshooting and resolving such an issue, offering a potential DIY solution for those facing similar challenges with their 2017 GMC key fob.
The author, a 2017 Silverado owner, initially received two key fobs from the dealership. Around 2020 or 2021, they began noticing two distinct symptoms: firstly, locking the doors with the key fob would result in immediate unlocking, and secondly, random unlocking would occur while driving or when the vehicle was in retained accessory power mode. Suspecting a faulty key fob, they isolated one fob, effectively stopping the erratic behavior and started using the second key fob instead.
However, a week ago, the same frustrating symptoms reappeared. Determined to find a more permanent solution, the author dedicated time to troubleshooting. Carefully opening the key fob casing, they discovered a clear, gel-like substance on parts of the circuit board and the inside of the case.
Through testing, this gel-like substance appeared to be conductive and the likely cause of the key fob malfunctions. Using a simple paper towel, the substance was carefully cleaned from the circuit board and the fob casing. After reassembling the 2017 GMC key fob, initial tests indicated a successful repair.
While the exact nature of this gel remains uncertain, the author suspects it could be leakage from the key fob battery. This wouldn’t be the typical corrosion seen in standard AA or AAA batteries, but a less common form of leakage. However, further investigation would be needed to definitively confirm this hypothesis regarding the 2017 GMC key fob battery.
The author intends to continue using the repaired key fob and will provide an update in a week to confirm whether this cleaning process has provided a lasting solution to the 2017 GMC key fob unlocking issue. This simple DIY fix offers a promising avenue for resolving similar problems without immediately resorting to key fob replacement or professional servicing.
