Hey everyone! I have been a Tahoe owner for about 6 yrs. I now own a 2011 Chevy Tahoe, Black. Recently I dropped the dob I think it's called lol. the clicker thingy to lock and unlock, anyways, I went to an Auto parts store and cheapest was $75 before tax, do I get it or is there a place I can find a less expensive one and how will I install it myself?? help!
