How to Remove the Shark Fin Antenna on a BMW 3 Series?

Bend the blade head to a 90-degree angle, as there is a groove at the shark fin antenna's mounting position. Directly cutting with force will not allow the blade to enter and may damage the paint and the shark fin. First, firmly tape the edges of the shark fin with art tape, but leave a gap for the blade to move. Slowly insert the blade head from the front of the shark fin and pull it backward horizontally with steady force. Insert a scraper into the already cut section and move it gently to avoid scratching the paint. Once the rubber separates, the shark fin can be removed.
Removing the shark fin antenna from a BMW 3 Series isn't actually that complicated. Let me share my DIY experience. The shark fin is usually glued onto the roof. First, use a heat gun or hairdryer to warm the surrounding area for a few minutes to soften the adhesive. Then, carefully pry it up from the edge using a plastic pry tool or an old credit card—avoid metal tools to prevent scratching the paint. Work your way around slowly; don't use too much force. If there's leftover adhesive, spray some adhesive remover and wipe it clean. Doing it yourself saves time, but afterward, check if the antenna hole is properly sealed to prevent leaks. The roof shark fin is often used for GPS or mobile signals, so removing it might affect navigation—consider installing a new antenna or leaving it off. Wear gloves for protection and choose a sunny day for easier operation. You'll get the hang of it after doing it once, but it's not a must-do—just handle it during routine cleaning or maintenance. Before starting, watch tutorial videos to ensure you're familiar with the process.
