Need power door locks installed

Hello all car talkers!

I just bought a 2005 Chevy Aveo and I want to install power door locks. My dealer assured me this was possible and sold me a power locks/alarm package. It turns out it’s not possible for them and they want me to find another place that can do the installation and they will pay for it. Do any of you know a place in the Boston area, preferably in East Boston, Cambridge, or Somerville? Any leads would be greatly appreciated.

Thanks!
