Introduction
An immobiliser is a device that prevents a vehicle from being started unless the correct key or code is used. This security feature helps protect a car from theft, but it can also be a problem if you don’t have the right key or code. If this is the case, there are several methods you can use to start a car without an immobiliser.
Jumpstarting the Car
One of the most common ways to start a car without an immobiliser is by jumpstarting it. This involves connecting two cars with jumper cables, so that the working car can provide power to the dead battery of the car without an immobiliser. To do this, you will need to park the working car close to the car without an immobiliser, and then connect the jumper cables to the batteries of both cars. Once the cables are connected, start the working car and allow it to run for a few minutes before trying to start the car without an immobiliser.
When jumpstarting a car, it’s important to take safety precautions. Make sure that the jumper cables are connected properly and securely. It’s also a good idea to wear protective gloves and eyewear to protect yourself from any potential sparks or electric shock.
Utilising a Bypass Switch
A bypass switch is a device that can be installed in the car to bypass the immobiliser. This allows the car to start without the need for a key or code. A bypass switch is easy to install and can be purchased at most auto parts stores. To install the switch, you will need to locate the immobiliser in the car, which is usually found near the steering column or dashboard. Once the switch is installed, you can start the car by simply flipping the switch.
Using a bypass switch has several advantages. It is much easier than jumpstarting the car, and it also eliminates the risk of electric shock. Additionally, the switch can be removed once the car is started, so that the immobiliser is still in place for security purposes.
Battery Check and Replacement
Another way to start a car without an immobiliser is to check and replace the battery. If the battery is dead or weak, it will not be able to provide enough power to start the car. To check the battery, you can use a voltmeter to measure its voltage. If the voltage is lower than 12 volts, the battery needs to be replaced.
When purchasing a new battery, make sure to get one that is compatible with your car. The size and type of battery should be listed in the car’s owner’s manual. Additionally, it’s important to get a battery with a high cold cranking amps rating, as this will ensure that the battery will be able to start the car even in cold weather.
Wires and Connections
The last step to start a car without an immobiliser is to inspect the wires and connections. Poorly connected or damaged wires can prevent the car from starting, even if the battery and immobiliser are working correctly. To inspect the wires and connections, look for any loose, corroded, or frayed parts. If any of these issues are present, they should be repaired or replaced immediately.
If you are not comfortable repairing or replacing wires and connections yourself, it is best to seek professional assistance. A mechanic will be able to diagnose the issue and make the necessary repairs or replacements.
Removing the Immobiliser
In some cases, it may be necessary to completely remove the immobiliser. This should only be done as a last resort, as it will leave the car vulnerable to theft. To remove the immobiliser, locate it in the car and then disconnect the wires leading to it. After the immobiliser is removed, the car should start without any issues.
Seeking Professional Assistance
If all else fails, it is best to consult a professional mechanic. They will be able to diagnose the issue and recommend the best course of action. Additionally, they will be able to repair or replace any faulty parts, such as the battery or immobiliser.
Conclusion
Starting a car without an immobiliser can seem like an impossible task, but it is actually quite simple when you know what to do. From jumpstarting the car to removing the immobiliser, there are several methods that can be used to get the car running again. However, if all else fails, it is best to seek professional assistance.
