2009 Cadillac STS Smart key Replacement - Fast, Affordable & Professional
I got a call from a customer at a Cadillac owners meetup near Simi Valley Dog Park. 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 291, exactly what I quoted on the phone. Dealer wanted 542 for the same job, and the scam locksmith charged more than both of us and couldn't even finish it.

“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”
“About 15 minutes after calling, he was already at my home. I had lost my original Ford key and he made and programmed a new one on the spot. Very fast, very professional.”
“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”
