The method for replacing the battery in a Haima key: 1. Press the button on the back of the key and pull off the upper part of the key; 2. Gently pry open the lower part of the key casing from the side; 3. Insert a small flat-head screwdriver into the gap at the top to pry open the battery cover; 4. Remove the old battery, replace it with a new one, and reassemble the key following the reverse steps. Taking the 2020 Haima 8s as an example, its body dimensions are 4565mm in length, 1850mm in width, and 1682mm in height, with a wheelbase of 2700mm. This model is equipped with a 1.6T turbocharged engine, delivering a maximum power of 143kW and a maximum torque of 293Nm, paired with a 6-speed manual transmission.
I've replaced the battery in my Haima car key several times myself, and it's quite a simple routine maintenance task. First, you need a small tool like a plastic pry bar or a thin coin to gently pry open the key casing along the seam. Be careful not to use metal tools to avoid scratching the key's surface. The battery is usually a CR2032 coin cell, which can be bought cheaply at supermarkets or online. After prying it open, remove the old battery and note which side the positive (+) mark is facing. When installing the new battery, make sure to place it the same way—don't install it backward, or the key won't work. Before reassembling, it's a good idea to clean the battery contacts, as dust buildup can interfere with the signal. Once everything is back in place, press the button to test the unlock function. If it works, you're done. The whole process takes less than five minutes. I think regular checks can prevent the hassle of a malfunctioning remote, especially before long trips—always test it beforehand.
I learned how to replace the battery in a Haima car key from a car-owner friend, and realized safety comes first. The steps are: First, confirm the key fob battery is dead by checking symptoms like reduced remote range or unresponsive indicator lights. Then, use a plastic tool or small screwdriver to gently pry open the casing along the seam, being careful not to damage the clips with excessive force. After removing the old battery (model CR2032), insert the new one with the positive (+) side facing the same direction as the old battery. To prevent static electricity, wearing gloves or working on an anti-static mat is recommended. Once reassembled, test all functions near the vehicle to ensure proper response. The whole process takes under 10 minutes and gets quicker with practice. A bonus tip: If the key doesn't work after replacement, check for dirty battery contacts and gently clean them before retrying. This DIY job saves dealership service fees and proves quite worthwhile.
Replacing the battery in a Haima car key is quite simple, just follow these steps: locate the seam on the key fob, pry it open with a flat tool; the battery is a CR2032 coin type, insert the new one with the positive side facing inward; finally, press the button to test the remote signal. I've done it myself—no professional tools needed, just a coin or small knife will do. Be careful not to insert the battery backward or apply too much force and damage the casing. If it doesn't work after replacement, it might be due to poor contact and may need cleaning. This method saves time and hassle.
