Mazda uses three versions of keyless start systems, and so three are back up start options. We will show them in reverse order, newer versions first, as they are now used throughout the line. So, here’s the scoop.

The CX5 was the first model to use Style 3 and by 2016 all Mazda models use this method. Push the brake pedal, or the clutch pedal if you have a manual transmission. This will cause the indicator light in the Start / Stop button to flash green. While it flashes, touch the back side of the key fob to the Start / Stop button, which will cause the green indicator light to stop flashing and remain lit. Push the Start / Stop button to start the engine as normal – or with the fob itself.

Style 2 is found in the CX7, CX9, MX-5 and RX8 models. Remove the Start knob cover by pushing both release buttons and pulling the cover off exposing the key cylinder. Slide the auxiliary key out from the bottom of the advanced key (see above) and insert it into the cylinder. Turn the key to start the engine.

For Style 1, found in the Mazda3 (including MazdaSpeed3) and Mazda6 prior to 2014, slide the auxiliary key out from the bottom of the advanced key (see above). Use the auxiliary key to remove the key slot cover located on the right side of the steering column. Depress the clutch (manual) or brake pedal (automatic) until the ring around the key slot starts flashing. Insert the auxiliary key into the slot while it is flashing, but do not turn the auxiliary key in the slot. Press the push button start to start the engine.

Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in the brake system and a new warning light may appear (left) or text message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.
