Can the installed ETC be removed and reinstalled?

[Marvin]

The ETC device in the car cannot be removed because there is an anti-tamper switch button on the back of the ETC device. After installation, this anti-tamper button presses against the windshield. If the device is removed, this button will automatically pop out, and the ETC service will be suspended. You will need to visit the relevant service outlet to reapply for positioning, installation, and activation before it can be used again. Precautions for using ETC: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, to prevent the ETC device of the vehicle ahead from malfunctioning or not having an ETC device at all, you should maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic sensing and paying for the vehicle ahead. The recognition speed for ETC lanes is 20 km/h. If the vehicle speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to become invalid. You can send it to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not due to human factors, it only needs to be reactivated.

Removing and reinstalling an ETC device is actually quite common—I've done it several times myself. If you want to take it off your car, whether because you've switched to a new vehicle or simply want to reposition it, no problem—just handle it properly. First, use a soft tool like a plastic scraper or credit card to gently pry open the adhesive-mounted base on the windshield. Be careful not to tug hard on the wires to avoid damaging the connector. Then, wipe away any leftover adhesive residue with an alcohol pad and clean the area thoroughly before choosing a new mounting spot—avoiding the rain sensor and wiper zones on the front windshield is safest. When reinstalling, secure the base firmly with new 3M double-sided tape to prevent wobbling. A critical step is reactivating the device post-removal, as ETCs are linked to vehicle data and may auto-lock; simply resync your account via the mobile app or service center. Wear gloves during the process to avoid scratching the glass, and test it at toll gates a few times to confirm smooth operation. Regularly checking adhesive wear is also a good habit—it extends the device’s lifespan while keeping things safe and hassle-free.

Last year when I removed and reinstalled the ETC for my wife's car, I discovered some small tricks to the process. When removing it from the old car, I used a heat gun to soften the adhesive before gently prying it off, as forcing it might crack the windshield. For reinstallation, I chose the upper side of the passenger seat area—convenient yet not obstructing the view. Only later did I learn that frequent removal and installation can affect the battery, so this time I spent a bit to replace the adhesive and reactivate it for proper use. My advice to regular car owners like me is not to rush the operation; try simple tools first. If the ETC stops working, don't panic—just call the service provider for a reset. Safety-wise, I always remind myself not to get distracted while driving; a falling device is no small issue. Sharing this experience in hopes that beginners won't make the same mistakes, saving both money and hassle.

The ETC device can be easily removed and reinstalled with simple steps. I've helped a friend do it: first locate the device, carefully peel off the adhesive and clean the surface; choose a new spot on the windshield to reattach it; finally, activate the account online to complete the process. Remember not to use sharp tools that might damage the device's wiring, and wearing gloves makes the operation safer. I always test it at toll gates to ensure the sensor is responsive, and adding a protective cover helps prevent dust interference during daily use.

Removing and reinstalling ETC is feasible but carries significant risks. From my own experience, forced removal can easily damage the glass or the device, and short-circuiting the wires is even worse. It's recommended not to attempt this yourself; instead, visit a professional shop for damage-free operation and free activation. Another pitfall is that battery life may shorten after reinstallation due to aging. Safety first—never take vehicle accessories lightly.

For frequent car changers, removing and reinstalling the ETC is a practical trick. I check and reinforce the adhesive every six months, choosing a high position to minimize obstruction. After reinstallation, I wipe it with a soft cloth to ensure normal function, and conserve battery for longer use. With simple care, daily maintenance becomes effortless.
