Car Kill Switch Ideas

Using a kill switch in your car cannot be effective without having the correct location. It has to be in a hidden place, a place not easy to identify by a thief. The best site for it is an invisible and difficult area difficult to access, like beneath a seat or under the ignition box. The control should also not be where fluids will damage it.

There are various ways to install a kill switch to get the best effect, which can be in the fuel system relay. With it installed in the fuel relay system, the fuel will not get to the engine for ignition to commence. It can also be in the battery to disconnect the car from starting.

Most car alarms come with kill switches to disable the car in case of theft. When the car alarm sounds and the car goes on to ignite without turning the kill switch off. The car alarm system automatically activates the kill switch, which prevents the car from starting.

Some car owners see the car alarm with a kill switch as the best combination to use for security, but it has a significant disadvantage. It has the burden of blaring at every touch of the car. There is no way to determine when there is an actual risk to prevent and when it’s just an innocent bypasser. The alarm can be quite disorienting and annoying.

Classic Car Kill Switch

Classic cars are rare and, most times, difficult to replace or buy their parts. Hence it is very crucial to safeguard classic vehicles from theft. Though kill switches are one of the best methods of safeguarding a car, not all of them are very efficient in classic cars.

The widely used kill switch for classic cars is the battery kill switch. It cuts power from the battery, and even if the thief hotwires the car, it will not start up because the energy from the battery is off. The ignition can turn, and the engine can spark, but the car will never start without a power supply from the battery. 

This kill switch is the best for classic cars. Ensure to install it with a professional to avoid damages that will cost replacement. Also, consider getting a more sophisticated security system if you are skeptical.

Best Kill Switch For Car

The automatic kill switch is the best kill switch for cars. It can kill the power from a vehicle when not in active use. It does this through motion sensors and GPS tracking devices and comes with a remote that allows you to turn off or on the button from a distance. This switch can also lock, unlock, start, and stop the car and even get the car’s location in case of theft. These configurations come with the kill switch and connect directly to the car system.

Another reason why it is the best is its accessibility. The car owner has no need reaching to the hidden switch to turn on and off at each car start-up. The remote turns on or off, alerting anyone of a kill switch in the car as a warning.

There are also different kill switches with different installation modus operandi, and they all work efficiently in preventing car hijacking. They include the battery kill switch, relay system kill switch, etc. read on to see how each switch operates.

Car Battery Kill Switch

When connecting the car battery kill switch, the switch is between the negative connector. The negative connector with the kill switches inside blocks power from the battery from reaching the engine. When the kill switch activates, it imitates the actions of a dead battery, but when it is deactivated, the power flow restores, and the car will ignite normally.

Since the disconnect switch is at the battery location, the on and off switch will be in a reachable hidden position inside the car for easy access. The car battery kill switch resets the car clock and radio settings whenever in use. This reset is because the battery holds the settings memory.

Remote Kill Switch For Car

The remote kill switch uses a remote control for operation. Using the remote, the car owner can easily access it from a remote location and activate it when there is suspicious activity.

It is installed in the battery, just like the car battery kill switch. At the same time, it uses magnets in the remote’s switch to control the control of the kill switch. The remote type has the same disadvantage as the car battery kill switch; it resets the car radio and timer settings.

Hidden Kill Switch For Car

With the rising population of cars in our society, finding a secure place to park is almost like wishing for a unicorn, hence the use of hidden kill switches for cars. It disrupts fuel flow to the fuel pump or electricity from the battery and ignition switch.

Hidden kill switches can be in the car hood, glove box, dashboard, under the seat, or anywhere out of sight. Installing more than one of these is not abnormal for maximum security. We can call all kill switch types hidden due to the aim to keep them away from thieves and vandals.

Magnetic Kill Switch Car

A magnetic kill switch uses magnets to control its switch. The attraction aids in turning the switch off or on. The use of magnetic in the remote gives the user remote access to it at all times.

With a standard kill switch, there is a risk of the thief locating the button, but with a magnetic type, you outsmart the thief by being with the remote magnet kill switch control right where you are. This switch can work with any kill switch type based on the location of a power disruption in the vehicle.

Fuel Pump Kill Switch

The fuel pump in a car controls the fuel flow to the engine, and it is impossible to start a vehicle without the fuel pump intact. The fuel pump kill switch disrupts the flow of fuel in the pump. Splice the fuel switch relay wire and insert the kill switch to install.

The fuel pump kill works so that the car will spurt and crank but not start. The car thief will assume it is an engine problem and go away. But the disadvantage of this type is its location. To turn it off, one has to go under the car to turn it off constantly. This is not an ideal switch for daily drivers.

Car Ignition

The ignition kill switch causes a break in the wiring. It is installed by cutting the ignition wire and inserting a connector on each side of the wire. The button is then attached to a hidden area inside the car.

Professionals often do the installation because one must cut through the correct wire to avoid severe damage. It has the advantage of misleading the car thief to assume the car has an engine problem and the switch location at any reachable hidden place.

Fuse Box

The fuse box kill switch cuts power off directly at the fuse box and not at the ignition. Car owners might prefer to pull out the ignition box and return it when they want to drive. But installing it to the specific fuses that need to disconnect to stop ignition and control it using a switch is easier.

How To Install

It is pretty simple to install a kill switch in your car, and you only need a few basic tools and the type of kill switch you prefer. The tools for installation include; wire cutters, a screwdriver, pliers, and cover tape. There might be a need to remove car covers and some panels to access the kill switch location. Ensure to read the instructions and follow them accurately.

  • Before proper installation, determine your car’s composition to kill with the switch and find the correct wire it goes along with.
  • Next, splice the correct wire and insert the kill switch into the wire. 
  • Tape the spliced wire up to avoid the wires touching.
  • Run wires from your car part with the kill switch disconnector to where the on and off switch will be. 
  • Install the switch in a private hidden place. 

With the right knowledge and proper tools, you can install it and have the safety of your car assured. If you do not have adequate knowledge to install the kill switch, contact a professional to install it.

Cost Of Purchasing

A kill switch costs an average of $10 to $100 for the part and the installation. The cost depends on the type of kill switch, model of car, and installation location. One can cut off the cost by installing it themselves, but it is not a good idea if there is no professional installation knowledge.

Compared to using a kill switch, it is much better to spend on it than on a new car. For $100 or less, a car owner can help safeguard their vehicle from theft. It is better than a steering wheel lock and a car alarm because it is not bulky and doesn’t give false alarms.

How To Bypass

To bypass is to override the function of the kill switch and start the car engine. There are only two reasons to bypass a kill switch:

  • If you want to find fault with the kill switch and find out if it needs replacement.
  • Avoid a car breakdown before you get to your destination in the event of a fault.

While there is no specific way to bypass a kill switch, you can do that by using a USB drive to connect to the car computer system. You can also use a cable to connect to the car’s diagnostic port and override from there. Access to the car’s Bluetooth module using a phone can also aid in bypassing a kill switch.
