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.
Step 3: Use Your Car Door Key
The door key can also be used to disable the Toyota immobilizer; simply turn the key on the door without actually opening it. To confirm that you have the correct key, hold the lock’s immobilizer unit in place for around 30 seconds. Try locking and unlocking by rotating the key from both sides. If the immobilizer detects the key, the action will help you get around it and deactivate it. Try starting the car now with the door open and the lock off.
If none of these approaches work, you can watch this video for instructions on how to get into your car’s engine control unit. In this situation, a Toyota immobilizer reset tool can also be necessary for assistance with some of the programming.

Q: Why Is My Immobilizer Light On?
Whether you have the correct key or not is indicated by the immobilizer light. If you start the engine, you will notice a solid light that will soon go out, proving that you have the correct key. However, the immobilizer light will start to flicker if you don’t have the appropriate key.

Does the immobilizer stop the starter motor?
A car’s engine cannot start if the proper key is not used, thanks to an immobilizer. The immobilizer operates by matching the transponder chip in the key fob with the codes in the ECU.
The engine won’t start if the engine computer unit does not receive signals from the proper key. Immobilizers for engines aid in preventing hotwiring and theft.
Can an immobilizer drain battery?

How Do I Turn Off My Toyota Car Alarm Without The Remote?

Can anti-theft prevent the ignition of the car?
Auto theft is discouraged by anti-theft devices. The majority succeed in doing just that. However, when anti-theft systems malfunction, they can bring along a lot of bothersome issues. Possibly, your car won’t start. Or, while you are driving, the system can suddenly turn off the ignition, causing your car to stall. If you use the key to enter the door, the alarm can also sound instead of turning off. Alternately, the alarm could sound for no apparent cause.
Anti-theft systems that are factory installed are typically more dependable and less likely to respond inappropriately than aftermarket anti-theft systems. The way the system is put in the car is one of the causes of this. The factory systems are typically built into the powertrain control module (PCM) and body control module (BCM), and they are intended to stop a vehicle from starting if the engine is started without the key. If a door is opened without first being unlocked with a key or keyless entry fob, many factory systems may additionally flash the lights and emit an audio alert (the horn or a second hidden horn). The majority of aftermarket systems are made to accomplish the same goals, but they can also offer remote car starting, GPS tracking in the event that a vehicle has been stolen, and even remote vehicle disabling.
The installer is the biggest issue with aftermarket installations. You shouldn’t experience any problems with the anti-theft system as long as it is functioning properly if the individual who installs it is adequately trained and does a quality job. However, if the installer splices into the wiring haphazardly, he may cause a number of possible issues. A crucial system’s electricity could be robbed by tapping into the wrong power circuit, leading to other issues that might not seem to be connected to the anti-theft mechanism. We’ve heard of aftermarket anti-theft devices that generated engine misfire codes as a result of briefly turning off the ignition while the car was being driven.
The caliber or durability of the electronics used in the anti-theft module is another problem with some aftermarket anti-theft systems. These days, a lot of electronics are made in China, and a lot of them employ very low-quality or recycled chips and other parts. As a result, after a year or two, the electronics start to degrade and the system either starts having issues or stops working altogether. The only solution to this is to purchase a system with the longest warranty possible, and then to cross your fingers that the manufacturer is still in business and will honor that warranty should you experience a problem in the future.
Diagnosing an Anti-Theft System Problem
When you try to start your automobile and the security or anti-theft light is blinking, but the engine won’t crank or won’t start, you may have an anti-theft issue. There could be a problem with the anti-theft module, the keyless entry system, or the wiring, or the system might not be detecting your key or keyless entry signal.
Can You Disable or Circumvent Your Anti-Theft System?
Probably not if the system was installed at the manufacture. Because these systems are intended to prevent auto theft, car thieves would disable or bypass them if they were simple to do so. Anti-theft systems can always be defeated, but the majority of these methods are either too time-consuming, expensive, or complex for the average do-it-yourselfer to attempt. In addition, if we revealed in this post the techniques for getting around your anti-theft system, we would be handing over the keys to your vehicle to anyone wishing to steal it.
If the anti-theft system is an aftermarket system, you might locate every location where it is connected to the wiring and disconnect the system if you have the installation manual or instructions that came with it. Alternatively, you might return it to the installer and request that they take it out or install a new system.
Only Car Dealers or Certified Repair Outlets Can Access the Anti-Theft System
One of the safety features built into modern anti-theft systems is the requirement that only employees of new car dealerships with factory scan equipment have access to the system for diagnostic or repair. Therefore, if you experience an issue with a factory-installed anti-theft system, a trip to the dealer for diagnosis and repair is likely required.
NOTE: Certified locksmiths who have passed a background check, are bonded, and meet all requirements for anti-theft access may also be eligible to access data on anti-theft services. But few people have enrolled in this program due to the costs involved.
Factory Anti-Theft Systems
Vehicle manufacturers employ a range of anti-theft systems: One system, the Content Theft Deterrent (CTD) system from General Motors, sounds an alarm if the doors are unlocked without the key. However, the technology cannot stop a car burglar from taking your automobile.
The Vehicle Theft Deterrent (VTD) or Passlock system from GM, the Passive Anti-Theft System (PATS) from Ford, and the Sentry Key Immobilizer System from Chrysler are examples of factory anti-theft systems that disable the ignition, the fuel system, or the starter to prevent your car from being stolen (SKIS).
Most people use an ignition key with a transponder chip that has been programmed. A transponder receiver in the ignition switch reads the key. The engine computer then receives a “go” or “no go” signal from the anti-theft module or body control module (BCM) after receiving the key signal.
The computer won’t engage the ignition, fuel system, or starter (depending on how it is configured) so the engine won’t start when you turn the key if the PCM receives a no-go signal from the anti-theft system or no signal at all.
