Yes absolutely! Many auto insurance companies give substantial discounts for customers who have quality security systems installed. They usually specify certain security systems that they consider reliable and secure enough to warrant handing out savings for. I've certainly heard of insurers backpaying in situations like this before, so you might as well try and see what they say. I believe you'll have a strong case, but check their small print!
So with our auto insurance policy on our SUV we have been paying a higher premium because we didn't realize until now that this vehicle actually has a built in basic security system. We've contacted our insurance company, and have been told we'll qualify for cheaper premiums now because of the security system. Should we try and get backpaid for the last 6 months that we've been overpaying?
