2026 Toyota Tacoma Electrical Problems

Your truck's smart key and door lock system is malfunctioning unpredictably. Doors lock by themselves while you're entering or exiting, the system sometimes thinks your key fob is inside the truck when it's actually in your pocket (preventing the truck from locking), and you're getting false "Key Not Detected" warnings on the dashboard while driving or trying to start the vehicle. Most concerning: if the truck loses key fob detection while you're driving and you turn it off, it may not restart even when you hold the fob to the start button, potentially leaving you stranded. The fix will likely require Toyota to reprogram or replace the smart key and door lock control modules.
