My sister-in-law just purchased a new Mazda3 sedan. She opted for a package that did not include keyless entry. She now regrets that decision and wants to install a system. In my brief research, it doesn't appear as though a dealer installed OEM system is available. So, to the aftermarket I go. Any recommendations? She lives in Minnesota, so a remote car stater might be a nice options for -20* winter mornings.

Thanks!

 

my recommendation would be to find an after market auto electronics shop to have them install one, would be cheaper than having a dealership do it.
