2009 Cadillac STS Smart Key Replacement - Fast, Affordable & Professional
I got a call from a customer at a Cadillac owners meetup near Third Ave Village. He'd already gotten burned once. He called one of those $49 Google ads for his 2009 Cadillac STS, the locksmith showed up and charged $520, and the smart key only partially worked. It would lock the doors but push-to-start was intermittent. He found me through Google Guaranteed and the first thing he asked was how he could verify I was legit before spending more money. Fair question.
I gave him my BSIS license number right on the phone, LCO#6792. He looked it up on the state website while we were still talking. I'm also NASTF certified, which means I have access to factory security data that unlicensed operators can't touch. I told him I'd fix what the other locksmith messed up and he'd pay what I quoted, nothing more.
I used my Smart Pro to reprogram his fob with the correct GM security sequence. His Smart Key, FCC ID M3N5WY7777A, came back with all 5 buttons working plus clean push-to-start. It came out to $332, exactly what I quoted on the phone. Dealer wanted $601 for the same job, and the scam locksmith charged more than both of us and couldn't even finish it.
