How to find the hidden key in your Nissan Sentra key fob

If you find yourself with a dead Nissan Sentra key fob battery, don’t worry! You can still get inside your car with the secret key hidden inside. We know that sounds like a complicated clue out of a mystery novel, but it’s actually a piece of cake.
To access your secret hidden key, simply press the release latch on the back of your key fob. Slide the latch up and you’ll see the emergency hidden key. Take the key out, insert it into the keyhole on the driver’s side door of your Sentra, and voila! You’re in.

How to start a Nissan Sentra when your key fob battery is dead

But once you’re inside, how do you start the car with a dead key fob? If you try to press the push-button start like normal, you’ll get a message that says, “No key detected.”
At this point, you may be tempted to give up and call AAA, but not so fast! You can start your 2019 Nissan Sentra with the dead fob by pressing the key fob against the push-button start. Make sure you’re pressing your foot down on the brake while doing so.
And there you have it! Make sure to pick up a replacement battery for your fob on the way home. 

How to enable Nissan Sentra key fob tricks

While unlocking and starting your 2019 Nissan Sentra are the most practical key fob tricks, there are a lot of fun, flashier key fob tricks to try. To take advantage of these, you’ll want tomake sure your key fob, or Intelligent Key, is properly programmed
If you purchase your 2019 Nissan Sentra from a dealership, your Intelligent Key should already be programmed with most of the key fob settings, but if you have to get a new fob, you might have to program it yourself. 
Follow these steps to program your fob and enable key fob tricks:
  • While seated in the driver’s seat, close and lock all doors.
  • Insert the key into the ignition six times. The vehicle’s hazard lights will flash twice to indicate entering Programming Mode. 
  • Put the key into the ignition and turn it to engage the electrics, but do not turn the car on. 
  • Then immediately press any key on the key fob (if this step is not done quickly enough, the key fob will not be programmed).
You can test that your car has been successfully programmed by stepping away from the vehicle and pressing a button on the key fob. If the vehicle responds, congratulations, you’ve successfully programmed your key fob!

How to lower your Nissan Sentra’s windows from outside

If you want to keep it cool in your Nissan before you even get in, this trick is for you! 
First, make sure your Sentra has automatic window icons on both front window buttons. If it doesn’t, you won’t be able to do this key fob trick. If it does, then just hold the unlock button on your key fob button. This will roll your driver’s side window down. 
Just be aware that you can’t roll up the windows remotely—you’ll have to get in the car to do that.

How to activate remote horn and lights

Do you often find yourself lost in parking garages, beating yourself up for not remembering where you parked? It’s okay—we’ve all been there. 
This trick will help you find your lost car—what a gift! 
Just press the lock button on your key fob and your 2019 Nissan Sentra will beep to alert you of where it’s parked. Thanks, little guy!
Speaking of beeping—if the horn feedback when locking your car is a little too aggressive for your taste, you can switch to silent mode and disable the horn by holding the lock and unlock buttons simultaneously. The lights will flash without engaging the horn. 
If you change your mind and want to bring back the beep, no problem! Just hold the lock and unlock buttons simultaneously once more. 

How to activate multiple driver’s profiles

This is our favorite trick! 
Let’s say that you and your partner share your 2019 Nissan Sentra. Your partner is 6’2 and you’re 5’3—you’ll have to constantly adjust your seat, mirrors, and steering wheel to suit your preferences, right? Wrong!
The 2019 Nissan Sentra’s key fob stores your unique preferences and allows you to access them at the touch of a button! Simply press the unlock button on your key fob when the light next to your driver profile number (either 1 or 2) is on.
Two drivers, one car? Not a problem!
