How to Deactivate the Anti-Theft System on the Buick New Regal?

Turn the key to the ON position, wait until the anti-theft light flashes, then turn the key to the OFF position. Finally, turn the key back to the ON position and wait for ten minutes until the anti-theft light flashes again, then turn the key to the OFF position. Repeat this process three times to deactivate the anti-theft system. Related details are as follows:1. Most car anti-theft systems contain an integrated chip with switching circuits. When an external trigger voltage is applied, the switching circuits open and output a positive voltage to drive the circuit, thereby activating the execution mechanism and alarm circuit.2. The radio remote control is a crucial component of the anti-theft system, utilizing radio signals to control various remote devices. These signals, once received by the remote receiving equipment, can instruct or drive other corresponding mechanical or electronic devices to perform operations such as closing circuits, moving handles, or starting motors, which then carry out the necessary actions.
As a former owner of a Buick Regal, I've encountered the anti-theft system activation. The usual deactivation method is: first, use the remote key to unlock the doors, and the system will automatically deactivate. If the remote fails, try manually inserting the key into the door lock cylinder, turn to the unlock position, and then attempt to start the engine—this often resets the system. The anti-theft activation might be due to doors not being closed properly or a dead key fob battery; replacing the battery or checking the door switch position should help. If unsuccessful, avoid forcing operations to prevent triggering alarms or damaging electronic components. I recommend carrying a spare key, regularly checking the remote battery and sensors, and if necessary, disconnecting the battery's negative terminal for a few minutes for a simple reset. For persistent issues, bring the vehicle manual to a professional repair shop for inspection—don't compromise safety to save a little money.
