01. How to change the battery in the “Egg-Shaped” Hyundai key fob?

Many people have asked me how they can change the battery in their Hyundai car key, so I thought it would be a good idea to write a blog post about this topic. The procedure is really easy and takes less than 15 minutes, but you need to make sure that you have all of the right tools beforehand.

Required Tools:

  1. A New CR2032 (3V) Battery.
  2. Flat Screwdriver.

Now, that you are ready, let’s the key battery change on your Hyundai.

Step-01: The first step is removing this emergency blade. Ensure that the slider has been slid out of place and then take out the bladder- it’s what we use to open your car if you forget to charge up your key battery, or if these buttons stop working. You’ll need a way in.

Step-02: The key is split into two all the way around, and you need to use this insert here that’s not on the blade hole. It’s in a little accommodating slot right next to it. Now if your hands are too shaky, you can do it with just a regular old screwdriver. Just gently place it onto there and give it one twist for an easy unlocking action without any hassle at all.

Step-03: The key cover is open now. A couple of things that are really important is not touching it otherwise you’ll have trouble with your vehicle starting.

Step-04: The key battery was removed from the top side of the lock. It’s not labeled, but when you put it back, you’ll see a label that is CR2032 (3V).

Step-05: When you change your car key’s battery, be sure to install a new one.

Step-06: Your new battery has a “+” sign, and you’ll need to make sure the plus signs on it match with those of your key.

Step-07: In order to change your Hyundai car key battery, you will need to take the old battery out of the slot. Put in a new one and join the two parts of your key together.

After replacing your key fob battery, don’t forget to reprogram it. All you have to do is follow the instructions below and restart.
