Buick Encore Key Fob Failure & Starting Issues Fixed

Had the same problem with my 2011 Buick Regal with similar symptoms. The key fob system completely failed, requiring manual key use for everything. The issue turned out to be more than just a battery replacement. Main problem was the vehicle antenna module located near the center console. Diagnostic testing revealed poor signal reception between the key fob and the car. The connection plug had corroded pins and damaged wiring, blocking proper communication. The repair involved: Testing the antenna mount connections, Replacing the corroded wiring harness, Installing new antenna module, Reprogramming the system It was a moderate repair job taking about 3 hours. The radio signal components were also affected, causing occasional FM antenna reception issues until fixed. The original radio system worked perfectly after the repair. The problem can worsen if left unaddressed, potentially affecting the immobilizer system. Would recommend getting it checked soon, as failing key fob systems often indicate deeper electrical connection problems that can affect other vehicle systems.

Thanks for sharing your experience. I also had this frustrating key fob issue with my 2014 Encore last year. Would you mind sharing what the total repair cost was in your case? Mine ended up requiring a complete automotive antenna replacement and new wiring, but I wonder if costs vary much depending on the specific damage. Also, have you noticed any issues since the repair? My car radio signal has been working perfectly since then, but I keep wondering if others experienced any recurring problems.

Thanks for asking about the cost details. After visiting the mechanic, the fix was much simpler than expected, just needed to repair a faulty cable connection to the bumper antenna. Total cost came to 95€ for parts and labor, which was a relief since I initially feared needing a complete antenna replacement like yours. The repair fully resolved all key fob issues and fixed the signal interference problems I was experiencing. The car radio and FM antenna reception have been working flawlessly for the past year. No recurring problems at all with the automotive antenna system or key fob functionality. This type of repair tends to be pretty reliable once properly fixed, especially when the issue stems from basic connection problems rather than complete component failure. Sounds like your case required more extensive work, which explains the difference in repair costs. Good to hear your radio signal is working well too, these antenna issues often affect multiple systems, so a proper fix usually resolves everything at once.

After dealing with the frustrating key fob situation, I finally took my Buick to a trusted mechanic last month. The complete antenna replacement with new wiring ended up costing around 400. More than I wanted to spend, but the thorough fix was worth it. The mechanic found significant corrosion in the antenna module and wiring harness near the center console. The repair took about 4 hours total. They had to remove parts of the interior trim to access everything properly. The car radio and key fob systems have worked perfectly since the fix. Really glad I got it done properly instead of trying cheaper temporary solutions. No more manually unlocking doors or dealing with poor radio signal quality. The peace of mind knowing the electrical system is properly repaired was worth the investment.
