The 2025 Tahoe can be equipped with special service vehicle packages for police use (RPO 9C1) (Fig. 7; shown with aftermarket equipment) and special service use (RPO 5W4).

On these vehicles, it may be difficult to learn additional Remote Keyless Entry transmitters (key fobs) to the vehicle during the immobilizer learn procedure. To address this condition, updated Body Control Module (BCM) calibrations have been released to assist with the immobilizer learn process. Be sure to update the BCM with the latest calibrations before learning new key fobs.
In addition, the location of the immobilizer coil has changed slightly on 2025 Tahoe models. The immobilizer coil (T10JA Low Frequency Instrument Panel Number 2 Antenna) is located further away from the ledge where the fob is placed during the immobilizer learn procedure. During the learn procedure, position the key fob with the buttons facing upward and the base of the fob towards the instrument panel center stack. (Fig. 8)

TIP: If it is still difficult to learn the key fob with the fob in the new position on the center console, the fob can be placed in front of the Start/Stop Switch (just below the ledge) with the buttons facing towards the rear of the vehicle.
If the Remote Key Pairing option is missing from the Settings menu on the infotainment screen (vehicles equipped with RPO 5W4), refer to #PIT6360.
Before beginning the immobilizer learn procedure, keep in mind that Content Theft Deterrent (CTD) is not available on vehicles equipped with RPO 5W4 or 9C1, which will cause a 2-hour timer for SPS IMMO Learn procedures.
For more information, refer to #PIT6388.
