Steps to replace the battery in a Hyundai ix35 key: 1. Press the silver round button on the car key; 2. While holding the car key, pull out the top part of the key to remove the mechanical key, which is used for manual door opening; 3. Use a screwdriver or another hard object to pry open the small groove inside the key; 4. Once a gap appears in the key cover, manually pry it open; 5. Remove the old battery and replace it with a new one, paying attention to the battery orientation to avoid installing it backward. The Hyundai ix35 is an SUV model with dimensions of 4420mm in length, 1820mm in width, and 1690mm in height, a wheelbase of 2640mm, front-wheel drive, a front suspension type of MacPherson independent suspension, and a rear suspension type of multi-link independent suspension.
I've been driving a Hyundai ix35 for several years and have changed the key battery many times. Usually, there's a small gap at the back of the key. You can gently pry it open with a coin or a small screwdriver. Inside, there's a coin cell battery, typically a CR2032 model—make sure not to reverse the direction; just follow how the original battery was placed when installing the new one. Close the cover firmly, then press the buttons to test if the car responds. If the light turns on, you're good to go. Buying a battery at a supermarket or electronics store costs just a few bucks—super cheap. I usually recommend not leaving the key in a hot car or near a phone, as it drains the battery faster. If you're worried about messing it up, searching for a tutorial video online can make it easier, or keeping spare batteries as backup can prevent being stranded if the battery dies unexpectedly.
The first time I replaced the ix35 key battery, I was a little nervous, but it turned out to be quite simple. First, locate the thin seam on the plastic case of the key and gently pry it open with a thin tool like a credit card—don't use too much force to avoid damage. Once opened, you'll see a small round CR2032 battery. Carefully note whether its positive side is facing up or down. Remove the old battery, insert the new one in the same orientation, and then snap the cover back into place. Next, test it: press the remote button—if the car lights flash or the door locks respond, it's working. If there's no response, check if the battery is inserted the wrong way. I recommend buying the same type of battery at a physical store; it won't take much time and can save you the cost of visiting an auto repair shop.
Replacing the battery in a Hyundai ix35 key is not difficult. Use a coin to pry open the shell gap, remove the old CR2032 battery. Install the new battery in its original position with the positive side facing up. Reattach the cover and test the functionality. The battery can be purchased for a few dollars at stores, handle it gently during replacement to avoid damaging the interior. If there's occasional poor contact, try pressing the buttons a few more times. Keep the key away from damp places as much as possible to extend its lifespan.
