How to remove the OBU?
3 Answers
The back of the OBU is attached with double-sided tape. When removal is needed, first use an electric heat gun to warm it up, then use a thin card to pry it off, and finally wipe off any residual adhesive with a cloth. The OBU is the electronic tag on the ETC device, which works in conjunction with the detection equipment at highway toll stations to enable automatic fee deduction and passage. The OBU should not be removed arbitrarily to prevent issues such as sensor failure or data loss. If a vehicle owner changes to a new car and needs to transfer the old OBU device to the new vehicle, they must bring their personal ID card, the original and a copy of the new vehicle's registration certificate, and drive the new car with the fixed license plate to the service center to complete the electronic tag transfer procedure.
Let me tell you how to remove the OBU. That thing is usually stuck on the windshield, looking like a small black box. You need to locate the right spot, often slightly above the driver's direct line of sight. Prepare simple tools, like a household hairdryer to heat it for 5 minutes to soften the adhesive—don’t keep it too close to the glass to avoid cracking. Then, use a plastic scraper or credit card to slowly pry open the edges, keeping the angle shallow and avoiding brute force. If there are wires connected, turn off the vehicle's power first to prevent electric shock risks. After prying it off, there may be adhesive residue—clean it with alcohol or adhesive remover. Stay patient throughout the process to avoid damaging the glass. I suggest practicing during free time, wearing gloves for protection. If done carefully, it’ll only take a few minutes. Once removed, you can clean the area and reinstall a new device. The key is to proceed step by step without rushing or making impulsive decisions to avoid accidental damage and costly repairs.
Safety first when removing the OBU. I think it's better not to mess around and cause problems. The OBU is fixed with adhesive, which is conspicuous but can easily damage the windshield. First, check the manual to confirm the connection method—many have power cables that need careful disconnection. Use a hairdryer on low heat during the heating phase, keeping it at a distance, and heat for 30 seconds before pausing. Pry it open with a plastic tool to avoid scratching the glass with metal. Before starting, ensure the car is turned off and the battery is disconnected, and wear gloves for a better grip. If you feel unsure or the adhesive is too tough, stop and seek professional help for peace of mind. After removal, check that the wiring and glass are undamaged, and use a professional cleaner to remove any residual adhesive easily. Consider the environment—avoid doing this in cold weather as the adhesive hardens and becomes harder to remove. Safety is the priority—don’t risk bigger problems to save a little money.
