2020 Cadillac XT4 Smart Key Replacement - Fast, Affordable & Professional
A guy in the Avenue neighborhood in Ventura called because his 2020 XT4 was locked behind a gated property and his only smart key was dead. Not weak battery dead. Gone dead. The fob got soaked in a pool the weekend before and never came back.
He had already called Cadillac roadside. They dispatched through Urgently, the third-party contractor GM uses now, and after an hour on hold he still had no ETA. His car was behind the HOA gate, and the tow company told him they needed 48 hours of gate authorization paperwork before they could even enter the property.
I drove out, parked on the street, and walked through behind a resident. His XT4 was sitting in the driveway. I connected through the OBD port, pulled the immobilizer data off the BCM, and started building his replacement. The HYQ2EB is a 5-button fob running GM's Hitag Pro ID49 chip on the newer E2 platform security. I cut the HU100 emergency blade, programmed the proximity fob, and ran the full theft deterrent relearn.
Then the part that actually matters: testing every function. Passive entry on all four doors, push-button start, remote start hold, trunk release, and walk-away lock. Everything answered.
He stood on his own driveway the whole time. No tow, no dealer drop-off, no two-day gate approval wait. Job done in about 35 minutes for a fraction of what the dealer quoted him on the phone.

“Fast, affordable, and a great price. Marco did an amazing job and made a key for our Nissan Kicks quickly and professionally. Everything worked perfectly.”
“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.”
“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.”
