Frequently Asked Questions (FAQs)

1. How much does it cost to put an alarm on a car?

The cost of an alarm system will depend on the features you select. Basic alarms can cost well under $100, and high-end ones can run upwards of $1,000, without labor. But there are a lot of in-between options. In fact, you can find very powerful and sophisticated alarm systems for only a few hundred dollars.

2. Is the car alarm connected to the horn?

The brain's job is to close the switches that activate alarm devices -- your horn, headlights or an installed siren -- when certain switches that power sensing devices are opened or closed.

3. Can I change the horn sound on my car?

The short answer is yes. You can change the sound of your car's horn if you find it too noisy or you prefer another option. The simple circuit that makes up the functionality of a horn makes the process even easier. But, you may want to consider the legislative laws governing car horns in your locality.
