I literally just bought a 2007 Mazda 3 for my daughter for her present for Christmas. She was provided with just one key from the used car dealer. She and I are wondering if she can obtain a key fob that unlocks and locks the door locks like my new Mazda 6

 

Contact your local Mazda parts department, give them the chassis number & they will tell you what's available.

 

Yes, .. I just contacted my mazda dealer and gave them the VIN # and they are looking into whether a keyless entry key fob was available for my particular Mazda 3. They will get back to me after Christmas. But I am impatient, .. if I give the vin # here would anyone be able to assist me?

 

I'd take a look here.
