Helloooooo
Expert:  Jared D replied 7 months ago.

Hi,

Sorry for the delay.

After replacement of the key fob batteries, will the lock/unlock buttons on the fob work correctly?

Customer: replied 7 months ago.
No
Expert:  Jared D replied 7 months ago.

First, make sure the battery in the key fob are installed correctly and if you have a multimeter check for at least 3v on the fob battery.

Do you have a spare fob?

Customer: replied 7 months ago.

Now it's blinking a red car with a key in it on display
Expert:  Jared D replied 7 months ago.

It's not very common for the device that receives the signal from the key to go bad on this vehicle. You might try to reset the system and see if it will start communicating again. If it doesn't work then you will have to take it to an infiniti dealer where they will hook up a scan tool that can reprogram the keys and the transceiver (the part that receives the signal from the key).

Here is how you perform a reset:

Customer: replied 7 months ago.
Expert:  Jared D replied 7 months ago.

Turn the ignition off and remove the key from the vehicle.

Remove both battery cables from the car battery.

Touch the cables together and hold them there for about 30 seconds to one minute.

Reconnect the cables like normal.

Insert the key into the slot and wait about 1 minute.

Try starting the vehicle.

Expert:  Jared D replied 7 months ago.

Before doing that try starting the vehicle by pressing the start button with the key fob.

Expert:  Jared D replied 7 months ago.

It sounds weird, but physically push the start button with the fob.

Customer: replied 7 months ago.
Where is the slot
Can't find it
Expert:  Jared D replied 7 months ago.

I'm sorry, your model doesn't have the charge slot. Just the push button. I think the 2014 models is when they added the slot.

Expert:  Jared D replied 7 months ago.

Your model doesn't have a slot like this to the lower left of the steering wheel right?
