Published availability and qualifications
Verified for 2025 Enclave gasoline models with keyless push-button start; the official guide identifies the left cupholder as the backup detection location.
Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Shift the Enclave to Park or Neutral and place the weak key fob in the left cupholder.
- 02
Press and hold the brake pedal.
- 03
Press ENGINE START/STOP and confirm its indicator turns green and the engine starts.

Replace the key-fob battery as soon as practical after the vehicle starts.
Important limits
- Use the left cupholder, not an arbitrary console bin, because transmitter-pocket locations are model specific.
- This procedure compensates for a weak fob battery; it does not repair a damaged or unprogrammed key fob.
Quick checks.
- ✓If the vehicle still reports no key, remove other electronic devices and keys from the cupholder and reseat the fob.
- ✓If neither programmed fob works from the backup location, use the owner's manual diagnostic guidance or contact a Buick dealer.
