My son took over my 2009 CX-9 after I bought a 2016 CX-5. In the past two months, he has been unable to lock the driver's side door without the alarm randomly sounding. It is annoying us, and our neighbors, to no end. We would love to be able to lock his car at night, but haven't been able to. There are no other electronic issues at all. We don't want to fix the alarm, we just want to disconnect/disable it. Is this possible without having to take it to a dealer and pay a lot of money for this? We tried disconnecting the battery and reconnecting it, but that did nothing to stop it from happening. We have changed batteries in the key fobs...any other ideas? We are desperate!
