How to Replace the Battery in an Old Sagitar Key?

To replace the battery in an old Sagitar key, you can use a 1-yuan coin. Insert the coin into a groove on the key and gently twist it to open the key, then replace the button battery. Below is some relevant information about car keys: 1. Introduction: Car keys offer functions such as locating parking spots and valet parking services. 2. Principle: They utilize the wireless remote control feature of the central locking system, allowing you to unlock and lock the doors from a distance without inserting the key into the lock. 3. Advantages: The biggest advantage is that, regardless of day or night, you can conveniently unlock (open) and lock (close) the doors from a distance without needing to locate the keyhole.

My old Sagitar's key fob has had its battery replaced three times, and the steps are super simple. There's a thin gap on the side of the key, right? Use a coin or your fingernail to gently pry open the shell along the gap—just be careful not to use too much force to avoid damaging the plastic clips. Once opened, you'll see a silver button battery, usually the CR2032 model. Simply pop out the old battery, making sure to note the orientation (check for +/- markings), and insert the new one the same way. After reassembling the shell, press the remote buttons a few times to test if the car responds. If it doesn’t, the battery might not be seated properly. It’s handy to keep a couple of these batteries at home—they’re available at convenience stores or watch repair shops. The battery tends to drain after 5–6 years of use, and DIY replacement saves a lot compared to visiting the 4S店.

Last time when I helped my neighbor aunt replace the battery in her old Sagitar's key, she was really nervous, but it's actually not that complicated. First, prepare a new CR2032 battery and a thin plastic sheet - these keys usually have slots on the back. Insert the plastic sheet into the seam of the key and gently twist to separate the casing (never use metal tools as they can scratch it). When removing the old battery, note the direction with the positive side facing up, then insert the new battery in the same orientation to power it. Finally, align the casing edges and press firmly until you hear a click. For testing, stand 2-3 meters from the car and press the unlock button to check responsiveness. If the battery is inserted backwards, the key light will flash but remote won't work - just reopen and reinstall it. I recommend doing this in dry weather as wet hands can make it slippery.

Replacing the battery in the old Sagitar remote key is a three-step process: open the case, replace the battery, and reassemble. The seam in the middle of the key can be pried open with a small screwdriver. The battery model is usually CR2032, available in the electronics section of supermarkets. After removing the old battery, check the positive and negative markings and place the new battery in the metal slot as before. When reassembling the case, align the internal clips and press gently. The whole process takes about two minutes. If the remote control distance shortens during testing, it indicates the battery is still insufficient. The key battery lasts about two years; replace it when the remote becomes unresponsive. After replacing the battery, remember to clean any dust particles inside the key.

Replacing the battery in an old Sagitar key requires some skill. The seam of the casing is quite hidden, so it's best to use a guitar pick or an old bank card—something plastic—to gently pry it open. Metal tools can leave scratches. Once opened, the battery holder has a metal clip; use a toothpick to gently push out the old battery. When installing the CR2032, make sure the side with the text faces upward; placing it backward will render it unresponsive. When closing the casing, snap the bottom first, then press the top until you hear a click to ensure it's properly secured. Once, I didn’t close it tightly enough, and it stopped working after getting wet in the rain. After replacing the battery, test the lock and unlock functions—stand next to the car and wait for the turn signals to flash to confirm success. For key batteries, it’s recommended to buy reliable brands like Panasonic for longer durability.
