mike5plus5 Posted October 13, 2016 Report Share Posted October 13, 2016 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?

Logan Posted October 14, 2016 Report Share Posted October 14, 2016 I don't know. The car originally came with 2 black keys....but it also had a single gray 'valet' key. That may have something to do with the 2 different part #s. Not sure what the blank one on the right is....not my pic.. mike5plus5 1 Quote Logan Diagnostic LLC www.airbagcrash.com www.logandieselusa.com www.ledfix.com www.ledfix.com/yukontaillightrepair.html www.ledfix.com/ledreplacements.html www.ledfix.com/j42385toolrental.html Link to comment Share on other sites More sharing options...
