Are they gonna mess up my car???

[Lillydot]

i'm probably gonna go to best buy or circuit city to get my keyless entry and alarm installed in my car. i called the dealership first, but they blew me off! first they told me it couldn't be done, then they told me it would be waaaay to difficult to do, then they told me it would be too expensive (without giving me a price quote!) so i'm stuck with best buy or ciurcuit city. but i don't trust them. my sister told me the poeple they hire at circuit city aren't even certified or trained! what's your experiences been like?
