I got mugged last night and my purse was stolen, including my only key to my 2006 GS 300. I didn't get a spare when I bought it used, so I only had the master. The thief that stole my purse has my key now, so I need to make a new key. My car is parked in front of my house so what should I do to get a new key? I don't want to get the whole ignition system changed, if I don't have to...Should I order a new master key online (like from Sewell) and ask a dealer to program it, or do they need me to bring the car in? I'd appreciate any advice- thanks!
