Refused to Start Suddenly

[xp0nex]

I encountered my first issue with the 4Runner today. When I tried to start it, nothing happened. The message “Press pedal and push engine switch to start” kept appearing each time I pressed the start switch. Eventually, the message changed to “Press brake pedal and touch power switch with key.” I followed the instructions, but instead of starting, the vehicle only went into “Power On” mode. After another attempt, the engine finally started.

I had already drove the 4Runner throughout the day and there was no issues. The odometer just rolled over 1,400 miles, and the vehicle was delivered in October. Maybe I should also check the key fob battery? Can’t be dying after 2 months?

I've had the same thing a couple times... dealership couldn't find an answer...but maybe hold the keys up to the push button start. That seems to work for me.

I swapped out my key fob battery with a spare. Hopefully, that was the problem.

It sounds like the vehicle may be experiencing a weak key fob signal. You’ve already checked the simplest solution by replacing the fob battery. If the issue continues, radio-frequency interference may be the cause. Low-quality electronics and some LED devices can generate electromagnetic interference (EMI), which can disrupt signals used by key fobs and garage door openers. I recommend unplugging any recently installed third-party accessories, such as dash cameras—ideally at the power source, since the cable itself can act as an antenna and emit EMI. If the vehicle is garage-kept, also check that the garage door opener is not using an LED bulb, as these are a common source of interference.

Sounds like a dead fob. Hold the fob up under the steering column.
