can you unlock a GMC Sierra without keys using just an airbag? It may sound like something out of a movie, but this unusual method works. Here’s how it is done: first, you need to insert the deflated airbag into the top corner of the driver’s side door frame. Then, quickly inflate the airbag using compressed gas or by forcefully blowing into it. As the airbag expands, it creates enough space between the door and its frame to allow for a long tool, such as a rod or wire hanger, to be inserted and reach the lock mechanism.
This unconventional technique has been popularized through various online videos demonstrating its effectiveness in unlocking GMC Sierra trucks. It is essential to note that attempting this method should only be done in emergencies or if you are locked out of your vehicle with proof of ownership.

With a Slim Jim:

The method used by professional locksmiths and even some car enthusiasts is utilizing a Slim Jim. This slender, flat metal can be inserted between the window and door panel to manipulate the locking mechanism.
First, slide the Slim Jim carefully into the gap between the window glass and door frame. Inserting it on the side where the lock is located is essential. Once inserted, maneuver the Slim Jim until you feel it connect with the lock rod. Push or pull on the rod while applying pressure toward the unlocking position on your vehicle’s lock switch inside.

With a Shoelace:

Tie a small loop at one end of the lace to unlock your GMC Sierra with a shoelace. Next, insert this loop into the top corner of the driver’s side door (or whichever door you try to unlock). Now comes the tricky part: slowly guiding the loop down towards the interior door handle using gentle yet firm movements. With some practice and patience, you should be able to hook onto the handle and pull it upwards. Voila!

With a Coat Hanker:

there is a simple trick that involves nothing more than a coat hanger. This clever method can be a lifesaver when you find yourself locked out of your truck with no spare key in sight. With just a few easy steps and some patience, you’ll be able to gain access to your vehicle in no time.
To begin, straighten out the coat hanger until it forms one long, slender piece of metal.

Next, bend one end into a small hook shape. Insert the hooked end between the window glass and the rubber seal near the door handle. Slowly maneuver the hook around until it catches onto the lock mechanism inside the door panel. Gently pull upwards while simultaneously applying pressure towards you to unlock the door.

 By Calling a Locksmith:

Locksmiths are trained professionals who specialize in unlocking various types of vehicles, including the GMC Sierra. They use specialized tools and techniques to safely unlock car doors without causing any damage. With their expertise and experience, they can quickly assess your situation and provide an efficient solution.
