You will need to insert the key fob in the slot designated for manual starting, then press the START button. The emergency start slot is located next to the steering column. 

If your Infiniti doesn't have a slot designed to insert the key, simply press the START button with the keyfob. 

Why can't I start my Infinity by pressing the Start button?

You press the brake press the start button. Nothing happens. Infiniti didn't even crank. If your push button is not starting the car, follow these troubleshooting steps:

  1. Check main car battery.
  2. Check key fewer fob batteries are in good condition.
  3. Faulty brake switch. If you are sure the car and key fob batteries are in good condition, next, you should check the brake switch.

How do I start my car if the Infitiy key battery is dead?

If the car does not start, the RKE transmitter (Key Fob) may have a low or dead battery. To start the car, try this: Put the nose side of the Key Fob against the ENGINE START/STOP button and push to operate the ignition switch.

How can I protect my worn Infinity key fob remote?

You may want to consider adding a cover to protect your remote. The covers can protect the buttons and the key fob remote itself. Our recommendation would be to use Silicone Key Fob Cover for Infiniti to protect the keyless remote. A cover will better protect the key from water in case you accidentally drop the key.
