🔧 PRO TIP
The redesigned CTS is fully proximity on all trims (FCC HYQ2AB, 315 MHz, 5-button, CR2032, HU100 blade). There is no base-trim keyed ignition option. CTS-V uses the same HYQ2AB smart key as the standard CTS with no separate immobilizer tier.

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

My van carries everything needed to replace a 2018 Cadillac CTS key without a shop. GM Z-keyway blanks, HU100 blanks, smart fob housings for every common Cadillac platform from the SRX through the Escalade, emergency blades, CR2032 batteries, ID46 and ID49 transponder chips, and a cutting machine bolted to the floor. The van is the shop. It just has wheels.

A homeowner at a gated estate in San Diego called because the tow company couldn't get past the property gate without prior authorization, and the HOA authorization process took 48 hours. His CTS was parked inside the gates with a dead smart key and no backup.

I drove in behind a neighbor and walked to his car with my tools. I used my VVDI2 to read the immobilizer data and program a new key through OBD. His Smart Key, FCC ID HYQ2AB, was a 5-button smart fob on the newer platform. I built, programmed, and tested it in his driveway.

His car never moved. Total was around $346 compared to $622 at the dealer. No tow truck, no HOA authorization delay, no leaving a Cadillac sitting for two days waiting for gate clearance. I walked through the gate with a tool bag and walked out with the job done.

Cadillac CTS Mobile Service FAQ

Real costs, no dealer surprises

I am locked out with no spare key. Can you come to me?
Yes. Call us and we will come directly to wherever you and your 2018 Cadillac CTS are in San Diego. We carry the tools and key blanks to handle your Cadillac on site. You do not need to call a tow truck, you do not need to get the car to a dealer, and you do not need to wait on hold with Cadillac roadside assistance. One Escalade owner spent an hour and a half on the phone with Cadillac roadside and they never showed up. We give you a real arrival window and we show up.
