Press the switch on the metal part at the back of the remote. While pressing the switch, pull the metal part outward to reveal and remove the hidden mechanical key. After removing the mechanical key, you can see the internal structure of the original metal part, with clips on both the front and back sides. Press and pull outward simultaneously to remove the battery module. Be sure to press all the way down; otherwise, forcing it may damage the clips. Remove the old battery and replace it with a new one, ensuring the battery's positive and negative terminals are not reversed.

I've been driving the Dongfeng Fengguang 330 for several years and have replaced the key battery a few times. Generally, you just need to pry open the back cover of the key shell. There's a small gap, and you can gently twist it open with a small flat-head screwdriver. Don't use too much force to avoid damaging the plastic. The old battery is a coin-type, most likely a CR2032 model. Just remove it, check the specifications, and buy a new one to replace it. You can get it for about 5 yuan at a supermarket or online. When replacing it, make sure your hands are dry and avoid dirtying the battery contacts, as this can affect the signal. When putting the shell back together, press it firmly until it clicks, then test the remote range. Keeping a spare battery is more convenient, so you don't end up needing a tow truck if the key fails on the road. This old car key is quite durable—with proper care, it can last up to three years.

Last time my Dongfeng 330 key fob stopped responding, and after struggling for a while I realized the battery was dead. I quickly went to a repair shop to borrow tools and replaced it myself. The specific steps are: use a coin to slowly pry open the key fob along the edge, separate the casing to remove the old battery—remember it's a small round battery with code CR2025, getting the wrong model would be wasted effort. Before installing the new battery, clean the slot to avoid poor contact, and take the opportunity to remove dust and keep it dry. After replacement, the remote worked perfectly—I recommend buying branded batteries instead of cheap ones for longer lifespan. Usually storing the key in a fixed place to reduce collisions can also extend battery life.

Changing the battery for the Dongfeng 330 key is quite simple: Step 1, locate a small groove on the side of the key and use a small tool to pry open the casing. Step 2, remove the old battery and confirm the model, such as CR2032, then purchase a replacement from a supermarket or auto parts store. Step 3, install the new battery with the positive side facing the correct slot to avoid reversing it. Step 4, firmly close the cover and test the functionality to ensure the unlocking distance is sufficient. The entire process takes about five minutes. Be careful not to lose small parts or scratch the plastic with hard objects; tools like coins or key rings can be used as alternatives.

I helped my elderly neighbor replace the battery in his Dongfeng 330 car key. First, I reassured him not to panic because the remote failure due to battery aging wouldn't affect driving. The operation involved gently prying open the key gap with a fingernail, avoiding any forceful breaking. I made sure to note the old battery model accurately, which was CR2025 or similar, and bought a new one for a few yuan at the supermarket. After installing the new battery, I taught him to press the test button to see if the red light flashed, indicating a successful replacement. I reminded him to check it regularly to avoid breakdowns and suggested carrying a spare mechanical key for added safety.
