Can the ETC be moved after being stuck on?

[LeVivian]

ETC cannot be moved once it is stuck on. Once the ETC is removed from the car's windshield, it cannot be used anymore and can only be reactivated by professionals. You can go to the original application point or the provincial highway ETC business office to reinstall and activate it, after which it can be used normally in the ETC dedicated lane. This is because there is a button on the back of the ETC. Once it is removed, the button will automatically pop out, and the information inside the ETC will be cleared, rendering the ETC unusable. Where can ETC be installed: For small vehicles such as cars and minivans, the OBU device should be installed in the upper middle part of the front windshield. For large vehicles such as trucks and buses, it should be installed in the middle lower part. ETC installation position requirements: the height should not be lower than 1.2 meters or higher than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane).

Last time when I installed the ETC, I didn't position it accurately and later had to adjust it myself. But you have to be extremely careful because there's an anti-tamper button on the back—if it pops out during the move, the device will be disabled. I used a hairdryer to heat it for a few minutes to soften the adhesive, then carefully cut through the glue layer with a thin fishing line. After removing it, I quickly cleaned the residual glue off the windshield and immediately repositioned and firmly reattached it. My hands had to stay steady the whole time, or the button could trigger a lockout. After reinstalling, I immediately tested it on the highway, and luckily, the barrier still lifted normally. However, I really don't recommend doing this yourself—a 4S店 technician said that out of ten people who try to move it, nine end up needing to send it back to the factory. It's best to position it correctly the first time on the right side of the rearview mirror where it doesn't block your view.

I just moved my ETC device two months ago. It looks simple, but the adhesive design is quite special - it's easy to trigger the anti-tamper mechanism when relocating. If you need to move it, be mentally prepared: get new 3M adhesive tape, alcohol wipes, and a hair dryer. Choose a sunny day, heat it for five minutes to soften the adhesive, then gently twist while removing the device. Never pull straight up vertically - always twist and lift simultaneously. Clean the new location thoroughly to remove any grease, press firmly for five minutes after installation. Most crucially, test it immediately by making a trip to the nearest toll station - if there are issues, you'll need to visit a service point for reactivation.

My ETC device has been stuck to the lower left corner of the windshield for three years without moving it. The installer repeatedly warned me not to touch it. These devices come with anti-tamper switches, with built-in spring plates tightly pressed against the glass – even a slight shift can trigger a lockout. If you really need to move it, drive to an ETC service center first. They use special adhesive removers to preserve the device. A colleague of mine damaged his by moving it himself and had to reapply for card activation, which took over a week. The newer ETC models now feature rotary pad designs, but older versions are mostly one-time adhesive mounts. It’s more convenient to position it with static cling film before permanent installation.

Last week, the car wash shop guy helped me relocate my ETC device, and it's indeed doable. The key is to evenly heat the adhesive pad to around 60°C with a heat gun until the glue softens, then slowly peel it off with a plastic scraper. The new position should be outside the black dotted area on the windshield to avoid signal interference. Drive through an ETC lane immediately after reattachment to test it—if you hear beeping alarms, you'll need to visit the bank for reactivation. He charged me 50 yuan for labor, which is much cheaper than reapplying for a new card. By the way, summer heat makes ETC devices most prone to displacement—once during heavy rain, my ETC adhesive pad came loose on its own, so I later switched to double-sided adhesive for a firmer hold.

I've relocated my ETC device three times. The first time, unaware of the anti-tamper mechanism, I forcibly pried it off and rendered it useless. Later, I learned my lesson: first purchase an ETC relocation toolkit online, which includes adhesive remover and anti-static stickers. During removal, keep the device tilted at no more than 30 degrees to avoid triggering the spring mechanism. It's best to perform the operation at around 20°C room temperature - in hot weather the adhesive becomes too sticky and may damage the wiring. The most secure new position is behind the rearview mirror in the black border area, where signal reception is significantly better than in glass corners. After relocation, test the card-reading function for three consecutive days - any single failure requires immediate attention. The newer models now come with detachable bases, making the process much easier.
