Home security systems are so expensive that it almost starts to feel like they don’t want us protecting ourselves or our homes. The good news is that you don’t actually have to fork out any money for a home security alarm providing you have one simple item.
All you need to do is take your car keys with you to bed and if you hear anything suspicious outside your home, press the panic button to set off the car alarm. This should be enough to alert your neighbors and scare the criminal away. The alarm will continue to sound until you switch it off (or the battery dies).
You will want to test the method first before relying on it to make sure that the alarm signal reaches your car! According to Wisebread.com you can extend the distance of the signal by holding the key fob under your chin making contact with your skin. Your body is a natural antenna and will help extend the length you can transmit the signal.
