I bought my car with a Clifford 750IQ.

My issue is that sometimes I come back to my car and it's unlocked and the hatch is open.

I'm pretty sure someone who parks near me has a remote for their car that also unlocks mine. Can I change some setting so that my remote works on a different code or something to that effect? If so, how?

Sorry for sounding newbish. I have a lot of experience with car audio, but I've never had an aftermarket alarm before. Thanks for any help.

 

I've never heard of the 750IQ but considering every reputable alarm made in the past 10 years has featured code hopping technology it is very very very unlikely that someone elses remote works with your alarm. It is much more likely that you are accidently pushing the trunk pop button while the fob is in your pocket or something like that.

I've got a Clifford 50.5x and when I first got it I would remote start it at least once each day at work and not know it until someone called me to tell me my truck was running in the lot. I no longer keep my keys in my pocket!
