How to Replace the Battery in a Reiz Car Key?
3 Answers
Press the release button on the key, pull out the mechanical key, and then you will see two holes: one is the mechanical keyhole, and the other is for removing the mechanical cover plate. Insert the tool between the two protrusions, twist it slightly with some force to open it, and you can proceed with the replacement. Below is some relevant information about the Reiz: 1. Exterior Design: The exterior design of the REIZ Reiz is captivating. It achieves a dynamic and elegant beauty with the best body proportions, embodying the luxurious charm unique to high-end sedans. The body surface is glossy, rich, and full, breaking through the traditional concepts of its class. It creates a futuristic and mesmerizing appearance, adopting the best body proportions and perfect structure for an FR sedan. 2. Interior Space: The Reiz surpasses its peers in terms of premium feel. It pursues perfection in the interior space of the REIZ Reiz, illuminated by self-illuminating instrument panels. The dark dashboard paired with a silver center console sets a sporty and fashionable tone. While the overall design is not particularly striking, it relies on meticulous detailing to create an atmosphere.
As an experienced mechanic who frequently repairs automotive electronic devices, replacing the battery in a Reiz key is not difficult at all. First, you need to confirm the key type—most are flat remote keys with small gaps in the casing that can be gently pried open using a blade or screwdriver. Inside, you'll find a common button battery, usually the CR2032 model, so I recommend buying a new one in advance. When disassembling, proceed slowly to avoid scratching the plastic shell. After removing the old battery, install the new one with the positive side facing up, being careful not to insert it backward. Before reassembling, it's best to test whether the buttons can remotely unlock the doors properly. The whole process takes just two minutes, but remember to keep your workbench clean to prevent dust from getting inside. If it feels too tricky, you can use specialized small tools to assist with opening the casing. Regularly checking the battery life can prevent sudden key failure from affecting your drive. Don’t underestimate this task—doing it yourself saves you a dozen bucks in repair fees. After years of repairing keys, the most common issue I’ve seen is inserting the battery backward, causing a short circuit and unresponsive buttons, forcing you to start over.
As a DIY car accessories enthusiast, I found the experience of replacing the battery for my Reiz key quite interesting. Last month, when the key stopped working, I guessed it was due to the aging battery, so I went to the supermarket and bought a CR2032 coin battery for just a few bucks. Using a coin or a thin card, I carefully pried open the key casing along the seam—avoiding excessive force to prevent damaging the clips. After removing the old battery, I noted its position and inserted the new one with the positive side facing up. When putting the cover back on, it snapped shut with a click. Testing the unlock and start buttons confirmed everything was working smoothly, and the whole process was hassle-free without spending unnecessary money. I recommend beginners to first watch a video tutorial on their phone for reference and keep a spare battery in the car for emergencies. Don’t forget to check the remote sensitivity after replacement—some cars regain a range of over three meters with a new battery. The sense of accomplishment from DIY is unbeatable, and it saves you half an hour of waiting time compared to taking it to a 4S shop.
