How To Bypass Toyota Immobilizer

You need to make sure everything is fine if your engine won’t start, which is a sign that the immobilizer is on and blocking entry. Make sure you are using the correct key, and if not, search for it. It is applicable when using a smart key or a separate key for unlocking the door and starting the ignition. If you believe that the smart key battery is dead, inspect the batteries on your smart key fob to rule out any potential problems and, if necessary, buy a replacement.

Additionally, make sure the door cylinder is in good condition. Sometimes when trying to enter, the robbers may put too much force on the door, which could damage the cylinder. If everything is in order, move on to the following action.

Step 2: Bypassing the System

When looking at immobilizer bypass methods, you must have your door key on hand. Instead of starting the engine, turn on the ignition after checking for the antitheft signal on your dashboard, which is often red or blue. After 10 to 15 minutes, leave the key in this position and check the anti-theft light again. Turn off the ignition and give it three minutes to rest if the light is not blinking. The immobilizing system recognizes your key and resets itself throughout the resting period. If your engine won’t start after your first attempt, try again after two more tries.
