Where is the child lock switch on the Regal?

[SanDaniella]

The child lock switch on the Regal is located on the rear doors, using a lever-type child lock. Detailed introduction to the child lock: Function of the child lock: When children are seated in the rear, it prevents active and unaware children from opening the door during driving, thus avoiding danger. In this case, the door can only be opened from the outside by an adult after parking. If the rear door cannot be opened from inside but can be opened from outside, it is highly likely that the child lock is engaged. This happens when passengers in the rear seat trigger the safety mechanism while getting on or off the vehicle, and it can be reset easily. Working principle of the child lock: The car child safety lock, also known as the door lock child safety, is installed on the rear door locks. Open the rear door, and you will find a small lever below the door lock. Push the lever toward the end with the child icon, then close the door. At this point, the door cannot be opened from inside but only from outside.

I was stumped by this issue when I drove my friend's old-gen Regal last time! The child lock is located on the side edge of the rear door, near the door lock position. You need to squat down to spot a small hole. Insert the mechanical key, turn it 90 degrees, and a click sound means it's locked—now the door can't be opened from the inside. The new-gen Regal is much more convenient: just peel open the door seal, and there's a small toggle switch on the side—push it with your finger and you're done. A reminder: only lock the side commonly used by rear passengers, otherwise you'll have to open the door for them every time they exit, which is quite a hassle. Though primitive, physical mechanical locks are more reliable than electronic ones. Last time during a heavy rainstorm, my nephew almost opened the door by randomly pressing buttons—thankfully, this hardcore design kept him safe.

With a decade of auto repair experience, I've dismantled hundreds of Buick doors. The Regal's child lock comes in two generations: the older version hides a keyhole in the door panel seam, requiring the tip of the car key to poke; the newer version places the switch directly on the black plastic area of the door frame side, with a raised lever you can feel with your fingers. Here's a pro tip—when engaging the child lock, first lower the window completely, reach your arm out from the outside to locate the switch most accurately. During testing, have the child sit in the safety seat and pull the door handle; when truly locked, you'll hear the latch make a dull 'click' sound. This design is most vulnerable to kids stuffing snacks inside and jamming it—last month, I repaired a Regal with its lock hole packed full of cookie crumbs.

Mom's Practical Tip: The child lock is located on the narrow edge of the rear door of the Regal. Last week when I took my two-and-a-half-year-old little rascal to the zoo, I had to squat down and search for a long time before finding it after securing him in the back seat. The switch on the new Regal is as small as a phone's mute button and can be toggled with just a fingernail. Remember to fully open the door to its maximum angle before unlocking, or your arm might get stuck and unable to reach. This feature, combined with the window lock, is a lifesaver for parents—no need to constantly watch the back seat on the highway. Once, my kid almost opened the door by messing around, and I was so startled that I immediately activated this switch. Physical prevention is a hundred times more effective than lecturing.

As a Buick salesperson, I always need to teach customers how to use the child lock when delivering the car. The Regal's child lock is designed at the door panel joint: lift the rear door and you'll see a silver metal latch on the door frame, with a round indentation next to it serving as the switch slot. Use a key to turn it clockwise to lock and counterclockwise to unlock. To test, try pulling the handle from inside the car—it shouldn't budge. If the door opens normally from the outside, it means the child lock is working. A special reminder: avoid directing high-pressure water jets at this spot during car washes. Last week, a customer reported the lock cylinder froze after water ingress. Also, don't confuse it with the window lock—the window lock button is on the center console, while the child lock is individually set on the door.

Last time I helped my neighbor move and drove his 2018 Buick Regal, I discovered this. The child lock is hidden behind the rubber door seal—you have to peel back the seal to see it clearly: a small black plastic slider with a child icon. Just push it all the way in the direction of the arrow; no key is needed at all. I recommend doing this when the car is parked, as the engine noise can interfere with judging whether it's locked properly. Once, my daughter was fidgeting in the back seat and accidentally kicked the switch open, nearly pinching her hand when getting out. So remember to check its status monthly to see if the slider has shifted. The hard plastic is quite wear-resistant; after six years, the switch still works as smoothly as new.
