You will also need to deactivate the immobilizer if getting into some auto sporting events. Some autosport regulating bodies will require you to disable this system before getting access to the course or track. Another instance where you may want to deactivate this car component is when you have a second-hand unit, and you want to change it.

Follow the steps highlighted below to know how to remove the Toyota immobilizer function.

Step 1: Check Your Key and Door Cylinder

If your engine fails to start, indicating that the immobilizer is on and preventing access, you have to confirm that everything is alright. Ensure that you are using the right key and if not, look for the right one. It applies in situations where you have a separate key for opening the door and turning on the ignition or using a smart key. Rule out battery issues on your smart key fob by inspecting them and, if possible, get a replacement if you suspect that the smart key battery is dead.

Also, check on the door cylinder to see if it is in the right shape. At times, the burglars may use too much force on the door as they try to gain entry, and it may end up damaging the cylinder. If everything is okay, you can proceed to the next step.

Step 2: Bypassing the System

Looking at how to bridge immobilizer, you need to have your door key to bypass the system. Check for the antitheft light on your dashboard, usually red or blue, then turn on the ignition to activate the car accessories rather than start the engine. Allow the key to rest in this position for 10-15 minutes, and recheck the antitheft light. If the light is not blinking, switch off the ignition and let it rest for around 3-minutes. The resting time makes the immobilizing system recognize your key and reset itself. Try and start your engine; if it does not start, repeat the process two more times.

Step 3: Use Your Car Door Key

You can also deactivate Toyota immobilizer using the door key, where you turn the key on your door as if opening it but do not open the door. Hold the key in place for around 30 seconds to let the immobilizer unit know that you have the right key. You can try turning the key on both sides, lock, and unlock. The action will aid you in bypassing the system and deactivating the immobilizer if it recognizes the key. Now try starting the engine, leaving the door in an unlocked position.
