How to Deactivate the Anti-Theft System on a Buick Regal?
2 Answers
Deactivating the anti-theft system on a Buick Regal involves the following steps: 1. Press the vehicle's brake pedal; 2. Engage the electronic parking brake to prevent the vehicle from moving during the deactivation process; 3. Tap the settings button on the central control screen and select 'ReaR'; 4. Click 'OFF' and wait for a moment until the anti-theft function is deactivated. The Buick Regal is a strategic model under the Buick brand, with body dimensions of 4913mm in length, 1863mm in width, and 1462mm in height, and a wheelbase of 2829mm. It is equipped with either a 1.5T SIDI direct-injection turbocharged engine or a 2.0T variable-cylinder turbocharged engine, paired with a 9-speed HYDRAMATIC intelligent transmission.
Recently, my Buick Regal's anti-theft system was falsely triggered, but I managed to fix it myself. First, check if the remote control battery is dead—try replacing it with a new one. If there's no response, use the physical key to unlock the door and start the car. Sometimes, the system activates due to sensor malfunctions or signal interference. Try pressing the unlock button a few times or disconnecting the negative battery terminal for 10 minutes to reset it. Remember to refer to the specific deactivation steps in the owner's manual—for the Buick Regal, it's common to press the unlock button twice. If these methods don’t work, it’s safer to get a professional inspection at a 4S shop, as a DIY mistake could leave your car immobilized.
