How to Replace the Battery in a Haima Key?
2 Answers
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.
