Experiencing issues with your Toyota Tundra key fob can be frustrating, especially when it intermittently stops working. One owner of a 2023 Toyota Tundra has encountered a perplexing problem where their key fob becomes unresponsive, displaying a “No Key Detected” message on the instrument cluster.
Initially, the original key fob would fail to communicate with the truck, preventing locking or unlocking of doors. Sometimes, the system would prompt to “hold FOB to Push/Start Button,” which would temporarily resolve the issue. Replacing the key fob battery seemed to fix the problem, but only for a short period, ranging from a day to two weeks, before the key fob issue would resurface.

Even after receiving a second, newly programmed key fob from Toyota, the problem persisted. The very next day, the new key fob also became unresponsive, leaving the owner unable to lock or unlock their Tundra. The truck simply wouldn’t recognize either key fob.
As a temporary workaround, the owner discovered that removing and reinserting the battery in the key fob would reset it and restore functionality, albeit temporarily. This suggests the problem isn’t necessarily a dead battery, but rather some other form of key fob malfunction or a communication issue with the vehicle.
To further diagnose the Toyota Tundra Key Fob Not Working issue, the owner plans to test if carrying both key fobs will make a difference, and try placing the fob in the center console cup holder area, as suggested in another forum post, to see if it restores communication. Toyota has advised towing the vehicle in when the issue occurs to allow for a diagnosis while the problem is active.

While a battery reset can offer a quick fix, persistent issues may require professional diagnosis to address potential underlying problems within the vehicle’s keyless entry system.
