Believe it or not, car alarms serve a purpose other than waking up the entire neighborhood at 4 AM for no good reason.
They are a great deterrent to auto vandalism and theft, and luckily come pre-equipped for most modern cars.
If you have an older model vehicle, you can have an alarm professionally fitted to help ensure its security.
Sometimes, your insurance will even give you a discount for installing a car alarm. A car immobilizer is an electronic device that you install in your car which prevents it from being started without the proper chip key.
It makes it harder for duplicate keys or hot wiring to be used to enter and start up your vehicle. Many modern vehicles come with car immobilizers, but like with car alarms, having an older vehicle fitted with one could possibly result in cheaper insurance rates.
