How to Disassemble a Tiguan Key?
4 Answers
The method to disassemble a Tiguan key is as follows: First, pull out the mechanical key from the car key. Then, you will see an opening mark at the bottom of the key. Use a small screwdriver to align with the opening mark at the bottom and turn it 90 degrees. Next, rotate the outer shell of the key to complete the disassembly. The four positions of the car key are: LOCK position, ACC position, ON position, and START position. The dimensions of the Tiguan are 4506mm in length, 1809mm in width, and 1685mm in height, with a wheelbase of 2684mm. The vehicle comes standard with features such as EDS electronic differential lock, EPB electronic parking brake, auto-hold function, and TPR tire pressure monitoring system.
Disassembling the Tiguan key is actually quite simple. I've done it myself several times. First, locate a small groove or gap on the back or side of the key, then gently pry it open with a plastic pry tool or your fingernail—don't use too much force to avoid cracking the casing. Inside, there's a small CR2032 battery; be careful not to reverse the polarity when replacing it, or the remote won't work. When reassembling, press the casing firmly until it clicks into place. I also recommend cleaning the contacts and interior after disassembly to prevent dust buildup from affecting connectivity, which helps prolong the key's lifespan. The Tiguan key's structure isn't complicated, and replacing the battery yourself can save you a hundred bucks compared to going to the dealership. Just make sure to work in a clean area to avoid losing small parts. If you accidentally damage the casing, you can buy a replacement shell on Taobao for around ten yuan.
I usually study the structure first when taking apart a key. The Tiguan's key typically has a small notch on the edge, and you can gently pry it open with a coin or plastic tool to separate the two halves. Inside is a button battery. When replacing the battery, I always remember to check for any corrosion points, clean them with an eraser to ensure a stable connection. When reassembling, align the parts properly to avoid misaligning the small internal circuit board. DIY maintenance is convenient and cost-effective—batteries cost just a few bucks at the supermarket, while repair shops charge extra for labor. Additionally, the key casing may occasionally develop cracks and let water in, so disassembling it for inspection in advance prevents rust and extends the remote's lifespan. Keeping some tools in the car is handy for emergencies.
I've disassembled my Tiguan key to replace the battery before, and the process isn't difficult. Find the small seam on the back of the key and gently pry it open with a plastic tool. Avoid touching the internal metal components to prevent static electricity. When replacing the CR2032 battery, make sure the '+' side faces up. After reassembly, test the remote buttons to ensure they work properly. Keep your hands steady during the operation to avoid damaging any parts. If you're doing it for the first time and worried about mistakes, search online for Tiguan key disassembly videos to make it safer and simpler. Proper key maintenance prevents malfunctions and saves both money and hassle.
