The GM transponder key, and how we set one up.
GM's B120 and B121 keys are the long ten-cut blades found on a huge range of Chevrolet, GMC, Buick and Cadillac vehicles from 2008 to 2020, from pickups and vans to sedans with a turn-key ignition. The two numbers refer to closely related blank variations, and we will match the one your vehicle uses. This version has a transponder chip in the head, which is what separates a working car key from a door-only copy. These keys commonly come in after the plastic head splits from the blade, or the blade has worn so much it sticks in the ignition. A worn key copied onto a fresh blank stays worn, so we prefer to cut by code to bring it back to factory depth. After cutting, the chip is programmed to the vehicle. GM has its own programming routines for these systems, some requiring a wait period, and we handle them with the vehicle on site, whether that is at our shop or in your driveway. Bring the registration and photo ID. Ask us to confirm which blank suits your truck or car.
How to order. Call with the SKU. We confirm the price, the stock and the fit, then cut, program or fit it. Items in stock are usually ready the same day.
