How to Replace the Battery in a Lavida Remote Key?

[Meghan]

The steps to replace the battery in a Lavida remote key are: 1. Eject the mechanical key, then pry upwards along the middle area on the side of the mechanical key to separate the key into two parts; 2. Take the part without the mechanical key, pry open the cover of the car key, remove the old battery and install a new one to complete the process. The Lavida (LAVIDA) is an independently developed A-class car by Shanghai Volkswagen. The car's dimensions are 4605mm in length, 1765mm in width, and 1460mm in height, with a wheelbase of 2610mm. It is equipped with a 1.6L inline four-cylinder multi-point fuel injection engine, delivering a maximum power of 77 kW and a maximum torque of 155 Nm. The Lavida features a MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear.

Changing the battery for the Lavida remote key is something I do often, and it's super simple. There's a small gap on the back or side of the key. Use a plastic card or a thin tool, like a guitar pick, to gently pry open the casing—don’t use too much force. Metal tools might scratch the surface. Once opened, you’ll see a small button battery, usually a CR2032 model. When removing the old battery, note its position to avoid installing the new one upside down—the positive side should face up. You can find the same battery model at supermarkets or e-commerce platforms for around 10 yuan. After replacing it, snap the casing shut and test the lock/unlock buttons near your car to ensure they work. Typically, a car key battery lasts about two years. If the remote starts acting up, it’s time for a replacement. Doing it yourself saves time and money.

As someone who frequently tinkers with cars, I recommend preparing a good tool before changing the remote battery for the Lavida. When prying open the key, focus on the side groove and use a plastic pry tool for easier operation—avoid using excessive force to prevent damaging the plastic clips. After opening, first check the model of the old battery to confirm if it's a CR2032 to avoid mistakes. Clean the contacts before replacement to prevent poor connectivity. Work quickly—once the new battery is in, immediately close and test it. A dead battery can cause the key to malfunction, but don't panic—it's usually something you can replace yourself. Check every three years or replace the battery when you notice the button's range shortening to prevent issues and avoid getting stranded with a malfunction.

The first time I changed the battery for my Lavida key, I looked up a tutorial online. I found the small notch on the key and used a plastic piece to gently pry it open. After opening the cover, I saw the round battery, took it out, and noted the CR2032 label to buy the same type at a small store. When installing, make sure the positive side faces up to avoid reverse installation, which would prevent it from working. Align the cover and press it back into place, then test the buttons. Be careful not to lose any small parts during the process, and operate in a well-lit area to avoid mistakes. It’s easy to handle and takes just a few minutes, making it suitable for beginners to practice.
