2003 SE Keyless Entry Question

Hello guys, I just bought a 2003 Grand Prix SE Sedan with keyless entry. I have never had a car with this option before. I was only given one key and one keyless entry remote but would like to get another key made in case I lock one in the car but I was told by a friend that these keys might have some computer chip in them. Will I have to go to a dealer just to get an extra key made?

Thanks for any info!

Most key shops can make one for you,but they arent a few bucks anymore.

They always list the FOBs on Ebay,which are GM and a heck of alot cheaper.Try doing a search on Ebay for GM key FOB they are around 5 to 10 bucks ......~Larry~

THanks for the info!
