2019 Cadillac ATS Smart key Replacement - Fast, Affordable & Professional
Cadillac uses GM's immobilizer platform, which means your 2019 Cadillac ATS has a transponder chip that communicates with the body control module every time you start the car. On older models it's an ID46 chip in the PK3+ system. On newer ones it's an ID49 with heavier encryption. The concept is the same. The car challenges the chip, the chip responds with a code, and the engine fires only if the codes match. That's why a hardware store blade copy turns the lock but won't start the engine.
A customer at Sam's Club in Santa Barbara thought only the dealer could handle that security handshake on her 2019 Cadillac ATS. The dealer quoted 612 and she assumed that was her only option because of the "computer programming" involved in Cadillac keys. Her neighbor had used me before and passed along my number.
I brought my Smart Pro to her car in the lot and connected through OBD. Her ATS uses a smart key, FCC ID HYQ2AB, with a transponder chip that my tool programs the same way the dealer's does.
Her spare was cut, programmed, and tested in under 30 minutes. Total was around 339. The technology is real, but the Cadillac markup on programming that technology isn't justified when a mobile locksmith carries the same tools.

Why Cadillac Owners Choose Us Over the Dealer
Real people, real savings, real reviews
“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“Tim was GREAT. I honestly swear he must have had my keys made before he even showed up. The entire process was insanely fast, from the initial phone call to having the keys in my hand. No one will beat the pricing, efficiency, or outstanding service.”
“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.”
