🔧 PRO TIP
DIY smart key programming with two working keys is supported on ATS in the same way it works on all GM push-button-start vehicles. If you have fewer than two working keys, a locksmith or dealer with professional tools is required.

2016 Cadillac ATS Smart Key Replacement - Fast, Affordable & Professional

I can usually reach you in Santee within 30 to 45 minutes. The 2016 Cadillac ATS key replacement itself takes 25 to 50 minutes depending on whether you have a working key or it's all-keys-lost. From phone call to engine running, most Cadillac jobs wrap up in about an hour to an hour and a half.

An insurance agent called at 8:15am. She had a meeting at 9 and her ATS fob had stopped working in the office lot. Push-to-start was dead and she had a client arriving in 45 minutes. She couldn't reschedule.

I was at her lot in 20 minutes. I decoded the lock with my GM Z Lishi and got inside, then connected through OBD. Her smart key, FCC ID HYQ2AB, needed a fresh CR2032 battery and a reprogram to clear the communication fault. Total hands-on time was about 20 minutes. I gave her a spare battery for the console so she wouldn't end up in this spot again.

She made her 9am meeting and paid $332 total. The dealer would have been $601 plus a tow plus a lost morning. She texted me that afternoon saying thanks.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

“Very professional and extremely affordable. The price was literally about three times cheaper than what my dealership quoted me. Fast service and no stress at all. Highly recommend.”

Cadillac ATS Mobile Service FAQ

Real costs, no dealer surprises

What if I need a Cadillac key after hours or on the weekend?
Most Cadillac dealer service departments close by 5 PM and have limited or no weekend hours. If you lose your key on a Saturday evening or any time after hours, you are stuck until Monday unless you call a mobile locksmith. Cadillac roadside assistance is listed as 24/7, but one of their own roadside techs warned that the third-party contractor Urgently is "a disaster" with longer wait times and unreliable dispatches. Even when roadside does show, they can unlock a door but they cannot make you a new key. We work outside of normal dealer hours so you are not left waiting days for a key.
