2018 Cadillac ATS Smart Key Replacement - Fast, Affordable & Professional

Keys stuck in the ignition is one of the most common Cadillac calls I get, and dealers always push a full ignition replacement. The Z-keyway ignition on older CTS, SRX, DeVille, and Escalade models develops a sticking problem tied to the shifter interlock or worn wafers. The key goes in fine but won't come out. The dealer quotes a new cylinder, new keys, and a full reprogram at $622.

A golfer at the club near Csusm Area had been dealing with a stuck key on his 2018 Cadillac ATS for weeks. He'd have to jiggle the shifter, turn the wheel, and pull firmly to free the key each time he parked. He was about to book the dealer appointment when he called me for a second opinion.

I checked the cylinder and the interlock mechanism. The issue was a combination of worn wafers and a sluggish park interlock sensor. So I used my ACDP to back up the body control module data before touching anything mechanical, then decoded the lock, replaced the worn wafers, and cleaned the interlock. His remote, FCC ID HYQ2AB, synced back up through OBD. I showed him the old wafers so he could see the wear.

His total was $346. The dealer's $622 included a full cylinder assembly he didn't need. The key comes out clean now.

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

“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.”
