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
Press the transmitter Lock button four times within three seconds so the operation indicator illuminates.
- 02
While that indicator remains on for five seconds, press and hold Lock for at least 1.5 seconds.
- 03
Wait for one hazard-light and confirmation-sound cycle.
- 04
Press any transmitter button and confirm its indicator no longer illuminates or flashes; button-operated remote commands still work.
- 05
To restore passive keyless and push-button-start functions, repeat the same four presses and 1.5-second Lock hold.
Important limits
- Power-saving mode disables advanced passive keyless entry and push-button-start detection until it is switched off.
- The remote buttons remain usable even though the transmitter indicator stays dark.
- Do not mistake an intentionally dark indicator for a dead key-fob battery without checking this mode.
Quick checks.
- ✓If the indicator does not first illuminate, repeat the four Lock presses more quickly.
- ✓If passive entry still works, make sure the long Lock press began while the five-second indicator window was active.
- ✓If the key is not detected after storage, repeat the sequence to turn power-saving mode off.
