Frequently Asked Questions
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.
Why can’t I start my Infinity by pressing the Start button?
You press the brake and press the start button. Nothing happens. Infiniti didn’t even crank. If your push button is not starting the car, follow these troubleshooting steps:
Check main car battery.
Check key fewer fob batteries are in good condition.
Faulty brake switch. If you are sure the car and key fob batteries are in good condition, next, you should check the brake switch.
IMPORTANT: The battery is 2032 NOT 2025 and 2032 is a totally different diameter.
The battery on mine is a 2032.
The battery type is molded into the plastic and says 2032.
In many cases these battery types are interchangeable. The 2032 is just a little thicker than the 2025.
The 2025 has less power so use the 2032 if you can as it will last longer.
