The used 07 Escape I bought a few months ago has a decal on the windshield that says there is a Chapman vehicle security system installed on the car. It probably was a dealer add-on. I'm hoping someone has experience with car alarms and security systems because I don't know where to look to see if the system is still in the car. And if it's there how do I determine if it works and what model of system it is? I googled Chapman and Code Alarm but didn't get any useful information. Thanks in advance for any help.
