2004 Cadillac CTS
Key Replacement - Save vs Dealer in Ventura County

2004 Cadillac CTS Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy near the Ventura County Fairgrounds who had been watching my YouTube channel for months. He said he originally found one of my Cadillac videos while researching why his 2004 CTS key was getting flaky, losing range on the remote buttons and sometimes needing two cranks before the SECURITY light would clear and the engine would catch.

By the time he called me, he already knew what the PK3+ relearn looked like. He had watched me do it on camera. Said that was the reason he saved my number instead of calling the dealer.

I drove out, cut a new B112 transponder key, and seated a fresh Megamos 48 chip. Then the waiting game: key to ON, sit through the first 10-minute security cycle while the THEFT light on the cluster counts down, off, back on, second cycle, off, third cycle. Thirty minutes of the car just sitting there thinking about it.

After the third cycle the engine fired clean on the first crank. I tested the remote lock and unlock from across the lot, confirmed no SECURITY light on start, and handed him the spare.

He stood there for a second and said he felt like he already knew the whole process before I showed up. That is the point of the channel. No mystery, no surprises, just the same person you watched online standing at your car doing the same work.
