I only have 1 ignition / door key for my 2003 Deville. I need a spare. So I want to buy a blank, then have my local locksmith cut it to fit my door / ignition, then I can program it myself. My question is exactly what part # key blank do I need for my 2003 Deville? Wholesale GM Parts Online shows 2 options if I looked this up right:
88956702 ; 88950014; 25674624 http://www.wholesalegmpartsonline.co.../88956702.html
and
88956703 ; 25674625 http://www.wholesalegmpartsonline.co.../88956703.html
Thanks for any help!
Mike
