2021 Cadillac XT4 Smart Key Replacement - Fast, Affordable & Professional
Here's exactly what happens when I replace a 2021 Cadillac XT4 key. I verify your identity and vehicle ownership. Then I decode the lock and cut the emergency blade so the mechanical side is perfect. From there I connect my IM608 to the OBD port, access the body control module, read the security password, and register the new fob through the security countdown. After that, I test. Not just "does it start." I test every button, the remote range from 30 feet, lock and unlock, trunk, remote start if equipped, and three consecutive push-to-starts.
A customer at the charity gala in Escondido watched me work on her XT4 and said the testing was what set it apart. She expected me to program the key and leave. Instead I walked across the lot pressing buttons, started the car three times, checked the remote start from 40 feet, and tested the range from multiple angles.
Her Smart Key, FCC ID HYQ2ES, was a 5-button smart key. I verified every button, checked the range from multiple angles, and did three clean starts. I told her that testing is the part most locksmiths skip, and it's also the part that catches problems before they strand you somewhere.
That testing process is included in the $291 I charge. Dealers charge $542 and some hand you the fob and close the ticket.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
“About 15 minutes after calling, he was already at my home. I had lost my original Ford key and he made and programmed a new one on the spot. Very fast, very professional.”
“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”
