2025 Chevrolet Suburban Replacement - Fast, Affordable & Professional
A guy from Moorpark College called about his 2025 Suburban. Said the push-start wouldn't recognize his key that morning, just kept flashing "No Remote Detected" on the dash.
When I got there, he was sitting in the driver seat pressing the brake and jabbing the start button over and over. The YG0G21TB2 fob was right there on the console. Battery tested fine at 3.1V. But the BCM wasn't seeing it at all.
I plugged in my J2534 and pulled codes. B1458-71 popped up, which pointed straight to TSB 23-NA-219. Early 2025 builds had a BCM calibration issue where the antenna sensitivity was set too low. The fix was a reflash, not a new key.
Eight minutes later, the BCM had the updated calibration. Key detected immediately. Start button worked like nothing ever happened. He kept asking if that was really it, like there had to be more to the story.
The dealer wanted him to drop it off for diagnosis, probably order a new fob at dealer markup, then discover the TSB during programming. Would have taken days and cost way more than my single service call to the college parking lot.

“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”
“Tim was GREAT. I honestly swear he must have had my keys made before he even showed up. The entire process was insanely fast, from the initial phone call to having the keys in my hand. No one will beat the pricing, efficiency, or outstanding service.”
“This is the only locksmith anyone should ever call. I am still shocked at how fast he arrived and the price was hundreds less than other quotes I received. Honest, professional, and extremely efficient.”
