How to Replace the Battery in an Old Magotan Remote?

[DeKayden]

Here is the method to replace the battery in a Magotan remote: 1. For keys before December 2016: To replace the battery in a car key before December 2016, push the lock pin of the emergency key to remove the mechanical key, then push the metal trim cover to remove it. Open the cover plate evenly along the gap, paying attention to the battery polarity (positive side outward). Use a small flathead screwdriver to remove the battery and install a new one of the same model. The installation method is the reverse of removal: install the battery, the trim cover, the metal cover, the locking mechanism, and finally the mechanical key. 2. For keys after December 2018: To replace the battery in a remote key after December 2018, push the locking mechanism of the emergency key to remove the mechanical key, then open the trim panel along the gap and gently push it outward to remove it. Use a small screwdriver to take out the battery, noting the battery polarity direction, and replace it with a battery of the same voltage. If the battery voltage is low or dead, the vehicle dashboard will display a warning: "Remote key not detected," prompting the driver to check the battery level. Reinstallation: install the battery, the trim panel, and the mechanical key to complete the battery replacement. Note: Incorrect battery replacement may damage the car key. Ensure the correct polarity and choose a new battery of the same size and specifications during installation.

I'm quite familiar with replacing the battery in the old Magotan remote. I've been driving this car for almost ten years. There's usually a seam on the back of the remote near the keyring. Use a thin flathead screwdriver to gently pry it open—don't use too much force to avoid damaging the casing. Once opened, you'll see a small button battery, model CR2032. Before removing the old battery, pay attention to the polarity; it's best to take a photo to avoid installing it incorrectly later. When inserting the new battery, align it properly and press it in gently. Then snap the cover back on and press lightly until you hear a click. After replacement, test the lock/unlock functions to ensure the signal is working. If it still doesn't work, you might need to check the wiring or the remote itself. Don't worry—this is a simple task you can do yourself, saving you the hassle of visiting a repair shop. You can buy the battery at any supermarket; just choose a good-quality brand for longer use.
