at my old work we had stock trucks without the keyless entry, and we had like 8 of these things put in. the one issue you will run into is if the door doesnt have the actuator arm in the door already. if it does, then it is less expensive (maybe like 200). however if you dont have that in your car then the whole actuator assembly must be installed. i think we ended up payin around 300 bucks a truck(this was a few years ago, the prices may have changed or i might have forgotten what we actually paid). we had ours done at some shop on freemans bridge rd in glenville, but i would call around to see who actually carriers the parts you need, and what it will cost to have it installed. (the stores that do it are most likely places like boomer mcloud or other car audio/accessory places)
