Experiencing issues with your 2020 Silverado Key Fob can be frustrating. Many owners rely heavily on their key fobs for daily vehicle access and operation. If you’re facing problems after attempting to reprogram your key fob, you’re not alone. One user encountered a series of unexpected issues during a DIY key fob reprogramming process for their 2020 Silverado, offering valuable lessons for anyone attempting the same.
Initially aiming to add extra key fobs, the user followed a standard reprogramming procedure. However, things quickly went awry after the first step of starting the vehicle. Instead of a normal start, the user inadvertently used the remote start feature. This seemingly small deviation triggered a cascade of problems. The key fob sensor relearn program malfunctioned, and alarmingly, the remote and even the dashboard start button failed to shut off the vehicle. Moving the key fobs a significant distance away also proved ineffective in stopping the engine. The vehicle became unresponsive, even preventing hood access.
After a tense 10 to 15 minutes, the truck finally shut off on its own. A subsequent attempt to restart the relearn procedure yielded only partial success; the original remote was limited to just locking and unlocking the doors. At this point, the user decided to pause the troubleshooting and revisit the issue the next day.
Returning to the task with a fresh approach, the user restarted the entire reprogramming sequence. This time, the process completed successfully, and the key fobs regained basic functionalities – locking, unlocking, and starting the truck via the dashboard button. However, remote start remained non-functional across all key fobs. Despite this partial victory, the user considered it a semi-success, concluding the day.
Interestingly, by the following morning, all key fob functions, including remote start, were inexplicably working perfectly. While the exact cause of this spontaneous recovery remains unclear, the user deduced a crucial insight: avoid using remote start during the key fob relearn procedure.
This experience highlights a potential quirk in the 2020 Silverado key fob programming process. It also suggests that allowing the vehicle to sit overnight might resolve certain key fob related issues, echoing observations from other online discussions regarding electronic glitches after modifications like window tinting.
Key Takeaways for 2020 Silverado Key Fob Programming:
- Avoid Remote Start During Programming: As demonstrated, initiating remote start during the relearn procedure can lead to complications and programming failures. Stick to a standard ignition start as instructed in your vehicle’s manual or programming guides.
- Patience is Key: If you encounter issues, especially after a seemingly unsuccessful programming attempt, allowing the vehicle to sit for an extended period, possibly overnight, might surprisingly resolve the problem. This could be related to system resets or electronic recalibration processes that occur when the vehicle is inactive.
- Follow Procedure Carefully: Ensure you are precisely following the recommended key fob programming steps for your 2020 Silverado model. Deviations, even seemingly minor ones like using remote start, can disrupt the process.
- Consider Battery Health: While not explicitly mentioned in this case, a weak vehicle battery or key fob battery can sometimes cause unpredictable electronic issues. Ensure both are in good condition before attempting key fob programming.
While this account is based on a single user’s experience, it offers valuable anecdotal evidence and practical advice for 2020 Silverado owners facing key fob programming challenges. If you’re attempting to program your key fob, learn from this experience and proceed with caution, avoiding remote start during the process and considering an overnight wait as a potential remedy for unexpected issues.
