Before explaining the different choices available to you, here is a short intro to explain the goal and operation of the immobilizer in your Chevrolet Tahoe. This electronic part appeared 30 years ago and aims to prevent the theft of your Chevrolet Tahoe. Indeed, thanks to a transponder and an antenna (coil) included in the key, and, a immobilisation control box included in the ECU and a reception antenna on the neiman, your Chevrolet Tahoe will go each time you place the key in the ignition, it checks that the code emitted by your key is actually the one expected by your immobilization box.
