🔧 PRO TIP
The 2006 CTS uses a transponder key that works through the ignition cylinder. The chip inside communicates with the immobilizer on startup. No remote, no fob, no battery to worry about. What trips people up is the theft deterrent relearn after a new key is cut. There's an onboard relearn sequence built into these cars. You cycle through it without a scan tool if you have a working key to initiate it. All-keys-lost is a different story. With zero working keys, you need equipment to access the security system and read the password before you can register anything new. The key blank itself has a GM dealer part number, but aftermarket blanks that accept the correct transponder chip cut fine as long as the blade profile matches the lock. Get the cut wrong and you'll crank the engine, get nothing, and assume the programming failed. It's usually the cut.

2006 Cadillac CTS Transponder Key Replacement - Fast, Affordable & Professional

I got a call from a guy in East Ventura, parked in his driveway off Telephone Road, completely locked out. His only key had snapped off in his jacket pocket at some point and he'd been using the broken half to start the car until the ignition finally said no. By the time he called me, he had a key blade stub and a car that wouldn't start.

I pulled up and the first thing I did was decode the lock cylinder. That tells me the cut before I touch any equipment. Once I had that, I cut a new key blade, tested the mechanical fit in the door, then the ignition. Smooth.

Then came the relearn. No working key means no shortcut. I connected to the OBD port, accessed the security system, read the password, and walked through the enrollment. These cars have a timed sequence built into the theft deterrent system. You don't rush it. I sat on his curb for that window, and he stood there watching like something was going to go wrong.

It didn't. First turn, the car started clean. I did it twice more, let it sit, started it again. He said he'd been white-knuckling that broken key for two months.

I was in and out in under an hour. He'd called the dealer first. They told him to tow it in, and the number they gave him was a lot more than what he paid me.

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Cadillac CTS Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys to my 2006 CTS. Can you still make one?
Yes. All-keys-lost on the 2006 CTS is a standard job. Because there's no working key to start a self-relearn, I use diagnostic equipment to access the security system, read the stored password, and register the new transponder. Then the key gets cut to the lock. The whole thing happens at your location. No tow required. Dealers default to towing because they won't come to you, not because the car needs to be in a shop.
Do I really need to tow my CTS to the dealer if I have no keys?
How long does an all-keys-lost replacement take on a 2006 CTS?
My 2006 CTS starts fine but the security light stays on. Is something wrong with the key?
Can I program a second key myself if I already have one working key?
