How to block the anti-tamper button of ETC?
2 Answers
It is impossible to block the anti-tamper button of ETC. The anti-tamper button of ETC is located next to the solar panel, which is a trigger-type dot connected to a switch underneath. After the electronic tag is installed, the windshield will press the anti-tamper guide rod in. If the ETC is removed, the anti-tamper guide rod will pop out and trigger the switch, causing the electronic tag to immediately become invalid. In this case, you need to go to a service point to unlock it. After the electronic tag becomes invalid, the ETC cannot be used normally. If the owner does not remove the ETC at will, the electronic tag falling off or loosening may also touch the anti-tamper switch. This situation is caused by improper installation of the ETC. When the car encounters bumpy roads or collisions while driving, it may cause the electronic tag to loosen.
I remember considering similar issues when I first bought my car. The anti-tamper button on the ETC device is quite sensitive and can easily deactivate the device once triggered. Some suggested covering the button with tape or paper to prevent it from reacting, but I later found this completely unreliable—the button is just the surface, and the internal mechanism detects displacement or pressure changes. Any forced covering could damage the device or cause the system to misinterpret it as tampering. When I really needed to move the ETC, I directly contacted the bank or highway toll station service points—they have professional tools to safely remove and reactivate it, saving effort and ensuring signal stability. Attempting DIY solutions like blocking the button is too risky, potentially causing circuit shorts or signal interference leading to failed passages, which might cost more in repairs. Develop good habits: don’t touch the button during installation, and use official channels for removal—this is far more effective than trying clever tricks.
