How to remotely start a Buick Regal?

[Yvette]

Buick Regal's remote start method is: first press the lock button to ensure the vehicle is locked, then long press the Buick logo button on the remote key. The remote start function enables preheating the engine, cabin ventilation, precooling in summer, and preheating in winter, making it an exceptionally practical and convenient feature. The Buick Regal is a mid-to-high-end sedan under SAIC-GM Buick, with dimensions of 4913mm in length, 1863mm in width, 1462mm in height, and a wheelbase of 2829mm. The vehicle features a large-sized winged chrome grille that expands horizontally from the centerline, where the shield-shaped upper grille echoes the outward-extended trapezoidal lower grille design. Combined with the side air curtain design, the front fascia presents a wide-body, low-stance sporty demeanor.

With my 2019 Buick Regal, I use the key fob to remotely start the engine every morning before leaving. Look for the circular button with an arrow on the key—first press the lock button, then hold the remote start button for 5 seconds. After the engine starts, the headlights will flash twice. In summer, it automatically turns on the AC, and in winter, it activates the heater. However, the car must be locked for this to work, and the range shouldn’t exceed 60 meters—it often fails in underground parking, which is annoying. Using the OnStar app is even better; you can start the car from your office before heading home and even adjust the temperature, though it requires an annual subscription. For older cars, key fob starting is the most reliable—it works flawlessly even after 7-8 years.

The remote start on older Regal models requires key fob operation. Locate the button with the small arrow on your key fob—first press the lock button, wait for the turn signals to flash, then press and hold the start button. Two horn beeps will confirm successful activation, and the doors remain locked while the engine runs. Note: This feature only works on vehicles with OnStar service installed and within a 60-meter range. Our repair shop often encounters owners reporting malfunctioning remote start—usually due to a depleted key fob battery. If unused for extended periods, start the vehicle every two weeks to prevent battery drain.

Using the OnStar App is the simplest way. Just install the app on your phone, log in to your account, select your car on the map, and tap the 'Start' icon. After starting, the air conditioning will turn on automatically, with the temperature defaulting to 22 degrees. There's an annual service fee, but it allows you to locate your vehicle anytime and remotely close the windows if you forget to do so on a rainy day. For newer models after 2020, you can even use your phone as a digital key, so you only need to carry your phone when going out. Some car owners in the group mentioned that the startup can be slow when the signal is weak, but overall, it's much more convenient than using a physical key.

The most hassle-free option is to buy the original key fob, the silver one. Don't touch the car key, just press and hold the start button on the key fob for three seconds, and you can start the car even through the garage wall. However, you need to visit the 4S store in advance for key pairing—some stores charge a 200-yuan matching fee. My neighbor uses this every day to take the kids to school, and the car is already warm when they leave. The downside is that this little accessory is easy to lose, so it's safer to attach it to your bag strap.

Buick owners should be most aware of these three starting methods: key operation is the most basic, mobile app is the trendiest, and key fob offers a balanced option. New car owners are advised to activate OnStar for voice-controlled startup. Owners of older models should regularly replace the remote battery—CR2035 models from supermarkets can be self-installed. If starting fails in underground garages, try moving closer as metal structures may interfere with signals. Southern drivers should note that external air circulation turns on by default after startup, while northern drivers in winter should preset the heating temperature in advance.
