2019 Cadillac XT4 Smart Key Replacement - Fast, Affordable & Professional

A retired couple near Coronado Shores needed a spare key for their 2019 Cadillac XT4. Getting to the Cadillac dealer wasn't simple for them. Neither liked driving on the freeway and the nearest dealer was a 25-minute highway drive. They'd been putting it off for months because the trip itself felt like too much trouble.

I came to their house that morning. Their car used a standard GM transponder blade with a separate remote. I brought my HU100 Lishi to decode the lock and verify the blade profile, then cut a fresh key and programmed the transponder through OBD. Their remote, FCC ID HYQ2EB, paired back up after a quick sync. I showed them how to check the fob battery so they'd know before it died on them.

They didn't leave the house. Total was $339 for two keys. The dealer quoted $612 for one. No highway drive, no coordinating a ride, no rearranging their week.

Cadillac XT4 Mobile Service FAQ

Real costs, no dealer surprises

Do I need to bring my 2019 Cadillac XT4 somewhere for key replacement?▼

No. EZ Car Keyz is a fully mobile service. We come to wherever your vehicle is, whether that is your driveway, your job, or a parking lot in Coronado. Cadillac dealers require you to either drive in with a working key or tow the vehicle to their service bay. One CadillacLyriq owner had their vehicle towed to the dealer for a "key not detected" issue and the dealer kept the car for ten days without fixing it. We handle everything on site and you keep your vehicle the entire time.
