Car Alarm System Installation Guide

Car alarms offer a certain percentage of security to your car to give you some peace of mind. Many cars already feature a car alarm system but some come without one. Even when you’re lucky enough to purchase a car that’s already fitted with an alarm system, you’ll want to fit it with a good quality alarm system to enhance the security of your car.

Fitting a new car alarm system is not a complex technical idea as many car owners may think. You can easily do it on your own albeit with sufficient data and appropriate preparation.  The process below will ease the car alarm installation process for you should you opt to do it yourself.

Have an Installation Strategy

Having a plan is the first step which can accelerate the installation process while cutting off many hours from your installation time. Collect together all the necessary documents you will need for the installation process. These could include manuals with exhaustive details regarding your vehicle’s wire polarities, their location, and their colors.

Test Your Car Doors

Inspect all your car doors to ensure that the door ajar indicator is functioning appropriately. If it doesn’t, then that should be the first indication that the alarm system won’t activate if someone tampers with the doors which eventually makes the alarm ineffective. Many car alarms feature elective pin switches which stimulate the alarm every time your car door opens. You can use these if you realize that your car doors don’t activate the door ajar indicator.

Research Extensively

Today, you can easily get all the information you need from the internet with ease. Look for manuals and search for wiring diagrams. Figure out the panels that you need to remove and understand the appropriate tools you need to execute the task. Remember, each car comes with a varying wiring layout and you want to study your car to better understand it. You could draw down a plan indicating where you intend to fix the car alarm system.

How to Fix a Car Alarm System

Here is a simple car alarm installation system.

Remove the Essential Panels

By removing the panels, you will be able to view and get access to the wires you need to connect the alarm system. Further, you’ll also gain access to other areas in your car such as the dashboard where you can fit in the alarm. In this case, you’ll need to remove the panels located along the central part of the dashboard along the driver’s side of your car.

Many times, these panels are either beneath the steering wheel or near the floor of your car. These panels differ depending on the make and model of your car. However, a car service manual should help you identify the ideal panels.

Fix the Car Alarm

Ensure you fix your alarm in a concealed area. While some people opt to fix it under the dash, you can choose to fit in other parts too such as beneath the driver’s seat. You don’t want to make the alarm system visible enough for potential thieves to see it. This way, you’re sure that no one will attempt to tamper with it. A hard to find car alarm system is often the most effective. Ensure to fit in all the accessories and screw that come packaged with the alarm system. Inspect surfaces before screwing through to avoid screwing through car parts or wires.

Drill across the Firewall

Identify a hole within the firewall and direct a wire straight from the car alarm to the siren. If you can, run the wire next to the core heater hoses, ignition power source, an amp power engine, or any lead penetrating which allows direct access through the firewall. If you can’t spot any hole, then you’ll need to proceed with the drilling process. Exercise caution when drilling to ensure that the spot you intend to drill is safe and will not cause damage to other parts of your car.

Drive a Wire across the Firewall

The wire connects the car alarm and the siren. Remember to insulate the wire using a rubber boot. Better still, you can choose to load silicon inside the hole to protect the wire from shorting out and getting destroyed when it gets into contact with the firewall. Secure the wire in a safe place out of human reach.

Affix the Siren

Decide where between your car’s engine bay and firewall is spacious enough for the siren to fit. Place the siren face down to ensure that water doesn’t accumulate around the voice coil.

How to Wire the Connections

The next step involves wiring your connections and this is how to go about it.

Fit in the Valet Switch

The valet switch enables you to divert all the alarm functions of your car albeit temporarily. With this option, you don’t need to give your transmitter to the mechanic or parking attendants. When the valet mode gets activated, the remote door locks and remote panic features will still be active.

Fit in the LED Light

The alarm system LED light shows active. To affix the LED light, you’ll need to drill a small hole through the dashboard and drive the wire towards the alarm module. The light is then affixed on the dashboard with superglue to secure it in place. Exercise caution when drilling to avoid hitting and damaging other parts of your car. This is an easy step and you may not need to dismantle the dashboard especially if you’re able to establish a secure place to drill your holes.

Fit in the External Antenna

The external antenna of your car is designed to draw signal from outside and convey it to the car alarm system. Many external antennas come as glass a mount antenna which means you need to affix a receiver on the exterior part of your car glass and another on the interior part of the same glass. The signal is then conveyed via the glass through the repeater wires and to the alarm’s antenna wire. This eliminates the need to drill holes.

Attach the Siren

Your siren should have negative and positive. Since many car alarms generate a positive siren, you may want to attach the alarm unit on the siren’s positive wire and attach the other siren’s wire to a ground.

Attach the Alarm Sensors

The sensors alert the siren when the car is tampered with to activate it. Attach the sensor wires from the alarm system to the dome lights or the wires which show door ajar. You may choose to attach them to the hood and trunk position sensors, or the ignition switch depending on the features of your alarm system. Rather than twisting your connections, you can either use a wire nut or simply crimp them.

Connect the Power Wire

Remember, your alarm should be powered even when the car is switched off. Connect your alarm system’s power wire to a sustained power source. This guarantees that the alarm is adequately powered and constantly active.

Restore Your Car’s Panels

When you’ve completed the alarm installation, restore your car panels exercising caution to ensure that they fit well together. You may want to follow the instructions on your service manual to complete the restoration process successfully.

How much does it cost to put an alarm on your car?

As we’ve mentioned above, many vehicles will come with a basic inbuilt car alarm. However, if you live in high crime places you may want to install a more advanced security alarm. Let’s find out how much you’d have to spend to upgrade your vehicle’s security system.

Average Costs

If you are looking for a basic alarm system complete with a siren connected to the car’s wiring system, remote control, and a controller, you should have an average amount of $30 and $300. Alarm systems that surpass this rate may feature more sensors and a back-up battery. Further, they may come with a starter immobilizer or a remote start to avert hot wiring.

Installing a basic alarm system comes at an average price ranging from $50 and $200 depending on how complex the system is, and the ease of accessing the car’s dashboard. This means you’ll spend between $80 and $500 to purchase and install a basic alarm system in your car.

Advanced Car Alarm Systems

You’ll spend an average cost ranging from $300 and $850 to purchase an advanced and modern car alarm system. This comes with more sensors, a complex computer controller, and is more effective. This system also comes with a remote ignition starter and a camera. You can use the disable car ignition starter option to cut off the gas supply in the event of theft. The average cost of installing the advanced car alarm system ranges between $100 and $450 and sometimes even higher depending on how complex the system is. Remember, you could spend more for a high-end luxury vehicle compared to standard models. The total cost of purchasing and installing an advanced car alarm system will, therefore, range between $400 and $1,300.

Which car alarm system is best?

Car alarm systems rely on various sensors to notice the presence of an intruder. You’ll want to pay more attention to this factor when choosing an alarm system for your car. While basic car alarms only feature door sensors, advanced alarm systems come with more sensors such as: door sensors, broken window detectors which go off when thieves break through your car window, movement sensors which go off when your car is either jiggled or bumped, and motion sensors which go off if there’s motion near your vehicle. The best car alarm system should be capable of giving your car comprehensive protection against various factors.

Now you know about car alarm installation

If you’re pressed for finances, you can opt for a basic car alarm system with door sensors only for a start. However, you may want to upgrade your system at a later date to ensure that your vehicle is well secured.
