I got a car alarm system from my sisters bf that he never used. He bought it from crutchfield, and it's a crime gaurd 745i4. It seems to be a pretty good product, but I'm unsure if it really is or not. It come's with the keyless entry feature which I really don't need since I already kinda have it. Here's the link for the one that I have http://www.crutchfield.com/S-SjQjyYq...x?i=514CG745I4 . If I was to have it installed would the factory keyless entry be rendered useless so I can use the alarm system and its keyless entry? I just wanna know what you guys may think about it. Thanks!

 

when i installed my alarm system, the factory keyless entry was pretty much useless , it works but if i use it instead of the alarm entry, you'll hear the siren go off

 

as opposed to???? stock? sure, why not add an alarm?

 

Well, it has good reviews... so use it. It does say it has remote lock/unlock, so your factory unit would be useless. But, make sure to bash the sh*t out of the factory remote, 'cuz like depsy said, you can still unlock your car w/it after the fact.
