Let’s take a look!
What Is The Purpose Of A Dashboard Warning Light In A Car?
Dashboard warning lights are an important part of any vehicle. They alert drivers to potential issues as soon as they start to occur, so you can take action and fix it before the problem becomes more serious. Dashboard warning lights come in many shapes and sizes, but all serve the same purpose – to inform drivers of a car issue that needs attention.
Are Some Warnings More Serious Than Others – How Do You Know?
Yes, some dashboard warnings are more serious than others. The severity of the warning is usually indicated by the colour of the symbol; generally means that there is an emergency that needs to be addressed right away, while yellow or orange typically indicates a less urgent issue. The exact meaning of a warning light can vary depending on your vehicle’s make and model so it’s important to consult your user manual or contact the manufacturer for more information.
Car With Lock Symbol On Dashboard – What Does It Mean?
If you see a car with lock symbol warning on your dashboard, it means that the vehicle’s anti-theft system has been activated. This typically occurs when someone attempts to start the car without the correct key. The warning light will usually be accompanied by an audible alarm and possibly other security measures such as the immobilisation of the engine.
How Does A Typical Cars Anti Theft System Work?
Most cars come with an anti-theft system fitted as standard, and for good reason. Car theft is a major problem in many countries around the world, so having an effective deterrent is essential. Anti-theft systems vary from car to car depending on their make and model, but they all tend to work in a similar way.
The most common type of anti-theft system works by disabling the engine when it detects that someone has attempted to break into the vehicle. This typically involves setting off an alarm if the doors are opened or tampered with in any way. The alarm will usually be loud enough to attract nearby attention and scare away potential thieves.
Aside from this basic security feature, some vehicles have more sophisticated systems which use sophisticated ‘immobilisers’. These prevent the car from being started until a secret key code is entered into a special device or an identification card is swiped through a reader.
Most of these advanced anti-theft systems can also be customised to suit individual needs, allowing for different levels of security depending on the user’s preferences. For example, some systems are programmed to respond only when certain components are triggered, such as sensors in doors, windows or the bonnet. This makes it harder for thieves to bypass the system and gain access to the vehicle.
What Causes A Car With Lock Symbol On Dashboard Warning
As mentioned above, the car with lock symbol warning is triggered when the anti-theft system has been activated. This usually happens when an incorrect key is inserted into the vehicle or when someone attempts to tamper with any of the doors or windows.
Below are some other common reasons for this error to be displayed.
1. Low Battery in Car
A car with a lock symbol on the dashboard warning can be caused by a low battery in the car. This commonly happens when the car battery is drained or old, causing it to no longer be able to supply enough power for all of the electrical functions of the vehicle. When this happens, the immobiliser will not recognise the keyfob and therefore does not allow access to start the engine.
2. Other Issues With Keyfob
Another possible cause for a car with a lock symbol on its dashboard warning is other issues with the keyfob. For example, if the keyfob’s circuit board or internal components have become damaged due to water ingress or age related wear, then the immobiliser will not recognise the keyfob, thus preventing access to start the engine.
3. Damaged Immobiliser
In some cases, a car with a lock symbol on its dashboard warning can be caused by a damaged immobiliser. The immobiliser is an electronic device which prevents the car from being started without an authorised keyfob. If it has become damaged due to age related wear or water ingress then it may no longer be able to detect and recognise authorised keyfobs, thus preventing access to start the engine.
4. Damaged Car Door Lock
Lastly, a car with a lock symbol on its dashboard warning could be due to damage or failure of the car door lock mechanism. Usually this happens when the door lock becomes jammed due to age related wear or water ingress. When this happens, the keyfob cannot be matched with the immobiliser, thus preventing access to start the engine. In this case, the car door lock must be replaced in order to regain access.
Car With Lock Symbol – How To Fix
If you have a “car with lock symbol” warning light displayed on your car’s dashboard, it is important to take action quickly. Here are some steps you should follow:
1. Check the key – Make sure that the key in your ignition matches the one provided with the vehicle. If not, then you may need to get a new key from your local dealership or locksmith.
2. Inspect the immobiliser system – The immobiliser system is responsible for preventing theft by disabling certain components of the engine when an incorrect key is inserted into the ignition. It also prevents starting when an unauthorised user tries to steal your car. To check if this system is functioning correctly, you will need to find out what type of immobiliser your car is using and then inspect it for any damage or fault.
3. Check the battery – A weak or dead battery can also cause this warning light to appear on your dashboard, so make sure that you check the voltage level with a multimeter before continuing. If the battery needs to be replaced, you should do so as soon as possible.
4. Diagnose other components – There could be an issue with one of the vehicle’s onboard computers, such as a faulty airbag module, that is triggering the warning light. To diagnose these problems correctly, you will need to use specialist diagnostic tools and software designed specifically for your specific make and model of car.
5. Contact your local dealership – If all else fails, it is always a good idea to take your vehicle to a local dealership or garage for expert diagnosis and repair. They will be able to diagnose the problem quickly and get you back on the road as soon as possible.

It can only be bypassed or overridden with specialized tools or through a complex process of removing, reprogramming, or replacing components. Attempting to do so without proper knowledge could lead to damage or permanent disablement of the car’s electronics system. Therefore, if you have a “car with lock symbol” warning light on your dashboard it is important to contact your local dealership or garage for expert diagnosis and repair.

1. Disconnect the battery
You can disconnect the power source of your car by taking off the negative cable from its terminal in order to reset any fault codes that may be causing issues with the immobilizer.
2. Try using a bypass module
These modules will allow you to override or bypass an active immobilizer without needing a new key. However, it is important to note that some vehicles require specific types of bypass modules that are compatible with their systems, so contact your local dealership or mechanic before attempting this method.
3. Lock And Unlock The Car Manually Using The Key
