How Does it Work?

Car alarms are designed to prevent burglary of the car and warn the owner if a theft attempt is being made. Usually a car alarm will output a high pitched sound when the system is triggered by vibration, closed or opened trigger switches or sensing of small and fast changes in battery voltage. Car alarms can also monitor sensors like infrared, microwave, ultrasound or tilting of the vehicle in the case of unauthorized towing. Some cars have alarm systems which send out SOS signals to a cell phone number in case of breakdown or theft. Alarm systems are also incorporated within a navigation system to increase the security of the car, the navigation system will send out a ping signal so the car can be received.


The security system can also be used to locate the car in large parking lots by using the conformation chirp on the remote fob. Sometimes a car alarm can give out a false alarm when it feels vibrations of thunder or a passing truck. Sensors need to be adjusted properly otherwise it can trigger the device even when a person accidentally touches the automobile as well.

Security systems utilize a remote controller (key fob) so a user can disable the alarm from a distance. The remote control feature is very convenient if the system is triggered by a false alarm. A key fob can integrate a variety of functions such as a LCD screen option which can project the image of a part of a vehicle that is under threat by a thief is one example.

Can you bypass an alarm system?

A damaged or faulty sensor would prevent you from arming your alarm, so bypassing this zone temporarily allows you to arm your system to protect the rest of the areas of your home or business. … In this case, you can simply bypass the zones that protect those areas and the alarm won’t trigger while they’re working.


An anti-theft system is so important that it saves in case of any theft of the car. The system can create disturbance and be very annoying in any case that it falsely engages. In such a situation, it’s so important for car owners to know how to disable the anti-theft system.

For you to be helped, make sure that you use the methods and the steps that have been discussed above carefully. If the car fails to start, seek help from a professional to solve the issue because other underlying issues prevent it from working.

How can I start my car without an Immobiliser?

Turn the key to unlock your car door, but don’t release it. Hold the key in this position for 20 to 30 seconds. This lets the system know you have the correct key, and it can allow you to bypass the alarm system. Some vehicles recognize the key simply by turning the key back and forth in the door lock key cylinder.

Call into the dealer, this is their response: Using the fob hit unlock button. Use the ignition key to start the car. Use the key to unlock the driver’s door. Remove the negative battery cable and then reconnect.

Use Key in Door

Another tip you can use to try to disable your anti-theft system is to use the key in the door. You want to make sure to use the driver side door and the physical key to having a chance of this working. Insert the key in the door lock all the way and then turn the key to unlock your car door, but don’t release it. You want to hold the key in the unlock position for twenty to thirty seconds. This lets the car recognize that you have the right key and will disengage and reset the system. If this doesn’t work, then you can try to turn the key back and forth in the lock a few times. Some cars will recognize the key this way if the key is being turned in the door lock cylinder. If using this method shuts the alarm off and disengages the anti-theft system, then you can try to start the car.

The Car Alarm Vs. The Anti-Theft System

While technically the car alarm is an “anti-theft” system – it’s not what we’re talking about here.

 Car alarms might be loud and useful for scaring off burglars, but they work better to prevent the theft of the things inside of the card than the car itself. In fact, even if the car alarm is going off, you can still get it started, provided you have the proper key, and the electronic immobilizer anti-theft system is working correctly.

Meanwhile, the immobilizing anti-theft system won’t make a sound, but it will keep a potential thief from taking off with your car. On the flip side, the system tends to act up, so it can keep you from getting the engine started.

Troubleshooting a Faulty Anti-Theft System

Just like every component in your vehicle – if it works now, at some point it can break; the same applies to an anti-theft system. While anti-theft systems are pretty reliable – occasionally they’ll act up, and it’s important to know what to do if something like that happens to you. 

How to Identify a Fault Anti-Theft System

Before diving into the anti-theft system to figure out what’s wrong, you need to verify if what exactly is the problem! 

If your anti-theft system is acting up, you won’t be able to start your car. Furthermore, you’ll notice a light with either a lock or a key on your dashboard (depending on what you drive). This is your security/anti-theft light. Sometimes your vehicle’s ECU will illuminate this light in conjunction with your check engine light.

This light can appear l even if the key is the problem – since it’s not picking up the transponder code. It will turn on when you try to start the car – even if everything in the system is working correctly!

Always Start with The Battery

Whenever you’re troubleshooting an electrical problem, start with the battery. Your vehicle might trigger the security light because the receiver isn’t getting enough power – and that is also probably why your car won’t start.

Bad or dead batteries are one of the most common reasons for a “faulty anti-theft system.” They’re also one of the most manageable problems to fix, but also one of the most overlooked. You can spend days chasing your tail if you don’t start with the simple things!

Reset the System

If you’ve checked the battery and everything looks normal, the next thing you should do is reset the system. This might sound hard, but it’s actually one of the easiest things you can do.

All you need to do is disconnect the positive terminal from the battery and leave it off for about 15 minutes before reconnecting. This resets your entire vehicle’s electronic components – including your anti-theft system.

This might not seem like it’ll do much, but if your vehicle’s anti-theft immobilizer does get tripped, sometimes it won’t reset unless you reset the entire system.

Check if the Steering Wheel is Locked

If you’re inside the car and can’t get the key to turn at all – it might be because the steering wheel is locked. Typically, this happens after the steering wheel, someone or something slightly turned the wheel after the key was out of the ignition.

This problem is more annoying than anything else and is relatively easy to fix – even if it does take a bit of persistence. 

All you need to do is wiggle the steering wheel around a bit until it loosens up. You’ll feel the noticeable difference. Sometimes you might need to turn the key in the ignition while trying to turn the wheel to get it to loosen up.

Take a Closer Look at Your Key

It’s the easiest component to see and the easiest to check for glaring defects. Each key has a transponder – and if that transponder is broken or missing, you won’t be able to start your car.

If you see anything wrong with the key, you’ve likely found your problem. If you have a spare key, this is extremely easy to check. 

Simply try starting the vehicle with a spare key after you’ve reset the system. If it starts, you’ve found the problem!

You’ll need to replace the key – as most manufacturers won’t fix just the transponder chip.

Read the Code!

If you’ve completed the previous steps and yet you still struggle with the anti-theft system, it’s time to read the code. 

Just like a check engine light, a code reader will tell you why the light is on. It might be that the receiver isn’t getting a signal from the key, or it might be that your receiver isn’t getting any power.

A code reader won’t tell you what you need to replace – but it’ll point you in the right direction.

Troubleshoot and Replace the Highlighted Component

This is where things get a little more complicated – since there are tons of different codes, there are tons of troubleshooting trees you could follow.

But when troubleshooting, keep the basics in mind. If you know how the system is supposed to work, you can’t reason out why it’s not working based on the code’s data. If the receiver isn’t getting a signal, it’s one of two problems – the receiver or the transponder.

Either way, you’ll need to get a key to match the new receiver – so you might as well save a little time and replace both components.

However, if a lack of power is your issue, you’ll need to dive into your electrical troubleshooting – or take it to a mechanic.

Method 2 of 3: Turn the ignition on

If the anti-theft system has locked up your engine, you won’t be able to start it. You’ll have to disable it with these steps.

Step 1: Check for the anti-theft light. It’s located on your dash and will have a blue or red light.

Step 2: Turn the ignition to the

Step 2: Turn the ignition to the “on” position. Insert the key into the ignition and turn it to the on position, which activates your accessories but not the engine.

Leave the key in position for about 10 – 15 minutes.

Step 3: Check the anti-theft light again. If it’s no longer blinking, turn the key back to the Off position and allow it to set for a minute or two.

This gives the system time to reset or you won’t be able to start your car.

Step 4: Start the engine. Attempt to start your engine.

If it still won’t start, check to make sure the battery hasn’t been drained.

Step 5: Repeat the process. Try the process over again to see if it will work.

Method 3: Insert the key into your car’s door

Step 1: Insert the key into the door lock. Even if you have a keyless car and do not typically use your physical key, use the side door on the driver’s side and insert the physical key into the lock.

Tip: Most, if not all, key fobs have a physical key within the fob. Look for a button that allows you to slide the physical key out of the fob.

Step 2: Turn the vehicle key to unlock the car door without releasing it. Hold the key for 30 seconds in this position. This will signal to your car’s system that you have the right key, and will enable you to bypass your car’s alarm system.

There are some cars that will recognize the key from you simply turning it back and forth in the door’s cylinder. It is best to try both methods: holding the key in the door, as well as turning the key both ways to disable the anti-theft system.

Step 3: Try starting the engine. Take the key out of the door and try starting your car’s engine. When you do this, however, make sure that the door cylinder remains in the unlocked position.

Unfortunately, it is possible to get stuck in a situation where either none of these methods work, or you are truly in a position where timeliness and care is critical. If you find yourself in this situation, or would simply prefer the help of a locksmithing professional, give your local Pop-A-Lock a call.
