can I program my new keys myself or do I have to pay big bucks
I think you're missing a digit on that part number.^ Bruce, key instrs. are in the owners manual. You can also program fobs yourself with the Dorman 604-15
Circle plus transponders go back to my 09 at least... Not sure if they used exactly the same transponder for all of the W-Body Circle Plus Impalas but the logo is the same.Yes, Bruce, that's it. What year/eng. is your car? You can get a "chipped" key blank from ebay for ~$10. Take it and the original key to Ace Hardware, Lowe's or a local locksmith to have it cut. $0-$5. Then, follow programming instrs. above. On my '12, '13 and '16 you want to look for an encircled "+" on the "chipped" key blank shank.
I'd take a whack at it if you're nearby... You have a PMAre you saying you'll program my remote for my 2015 Impala? If so, send details.
