Great question! Learning how to open a Nissan Sentra key fob is a fairly straightforward process but can be a bit tricky the first time you do it—that’s why we’ll walk you through it. Before you start, you’ll need to get a small flathead screwdriver and a pair of latex gloves. The gloves are to avoid damaging the fob’s electrical components.
Now that you are ready, follow these steps:
- Flip the key fob over
- Unlock the emergency key by moving the small slider. Remove the emergency key.
- At the top of the key fob, find the open notch between the front and back halves.
- Insert your flathead screwdriver into the notch and turn until the front and back halves of the fob separate.
All done! Now you can remove and replace the dead battery. Once you do so, line up the front and back halves and press them together until they click back into place.
