How To Start Toyota Camry Without a Key?

The earlier models of Toyota Camry depended on a key for ignition and to open and lock doors. The physical keys had fewer chances of failing compared to the modern ones. The newer models, however, use a remote for various functions, including ignition.

Camry TRD is also equipped with smart entry and start, allowing you to operate the car without a key. However, not all modern Toyota Camrys use a push button since the LE and SE trim only offer the push button as an option.

In case your key fob malfunctions or runs out of battery, there are various ways you can start the engine. Following are some ways to start your Camry in some scenarios.

1. Scenario One (Start Camry with Push Button, Key Fob Failed)

Follow the following steps

  1. The key fob has a button that releases the key inside. The button can be on one side of the key fob or the top side. Press the button to release the key from the key fob and take it out.
  2. Use the key to unlock the door and get into the driver’s seat. One turn right and back opens the driver’s door, but two turns open the rear door too.
  3. Your key fob has a unique low-frequency signal that it transmits using the radio-frequency identification (RFID) chip and antenna within it. The car’s computer reads and validates it when you push the start button.

If the key fob is dead or malfunctions, the computer can’t validate it automatically and must scan it. Press the fob slightly against the start button, press the brake pedal, then push the start button to start the car.

2. Scenario Two (Start Camry with Push Button, Key Fob Working)

There’s also a way to start your Toyota Camry by using the key fob, but without physically pushing the start button. The scenario is common when you want to warm up the vehicle without doing it manually. Follow the following steps:

  1.  Make sure you’re within 80 feet or 24 meters of your car.
  2. Aim your key fob at the vehicle and press the lock button three times. The first two times, press the button quickly.
  3. For the third time, press and hold the lock button for three seconds. The turn signals will flash, and the engine will turn on.
