Here are the steps to replace the battery for Renault Koleos key: 1. There is a circular button beside the key, press it downward and pull out the mechanical key from the outside. 2. Use the mechanical key to tap those two parts from above. 3. Take out the old battery and insert the new one. Be careful not to reverse the positive and negative poles of the battery. 4. Install the battery correctly with the positive and negative poles in the right positions. 5. After installation, do not immediately reassemble the key. Before reassembling, press the square button on the key. If the indicator light flashes normally, the process is complete. Here is some related information: When the internal battery is low, the remote control distance and sensitivity will decrease. Sometimes, the door cannot be unlocked remotely, or the remote control may not respond. Some vehicles will display a low key battery warning on the dashboard.
To replace the Renault Koleos key battery, I recommend starting by checking the battery life. If the key buttons respond sluggishly or fail completely, it's likely due to a drained battery. Prepare a small flat-head screwdriver or a hard card, along with a CR2032 coin cell battery (available at supermarkets or auto parts stores). Locate the seam in the middle of the key casing and gently pry it open—avoid using excessive force to prevent damaging the plastic clips. After removing the old battery, insert the new one with the positive side facing up and ensure good contact. Reassemble the casing, then press the buttons to test if functionality is restored. As a side note, the key design includes a hidden mechanical part, so remember to tighten or secure it properly to prevent loss. Regularly replacing the battery every two years can extend the key's lifespan. With a few tries, you'll get the hang of it—simple, cost-effective, and saves you a trip to the repair shop.
