Remote was first made with the FCC ID OUC60270 and part number 15913418. GM soon discontinued that part number and superseded it with these: 22756461, 15913418, 15857836, and 20868672. The FCC ID rolled from OUC60270 to OUC60221. At the time this description is being written the current GM part number is 20869055. All these part numbers are unimportant because there is nothing unique about them other than the number printed on the back of the case. They all contain the same circuit boards.
2007-2010 vehicles are onboard programmable, meaning you can program the vehicle to accept new remotes yourself easily with the included instructions. 2011-2014 vehicles are not onboard programmable, meaning you will need a local automotive locksmith or dealer to use programming equipment to program your vehicle to accept new remotes.
This remote is used on vehicles built for the US market. It is a 315MHz remote with 5 buttons (Lock, Unlock, Liftgate, Glass Hatch and Panic.)
