Let’s get started with the first technique, shall we?


How To Unlock A GMC Sierra Without Keys

Technique 1:


  • Plastic wedge
  • Air wedge (Airbag)
  • Remote Control Button Master.

Alternatively, you can use any pole stick with a hook or nozzle at the end.

Preferably two air wedges that you can use because they provide a bigger gap for easy manipulation.

Plastic wedges can be an alternative. you can also use a screwdriver or pin to pry the window. But be careful.

Sharp objects may create a dent on the door or damage the door gasket and window ribbons.

A shoelace or a hanger also can be used.

You need a tool that is thin and will fit through the window space.

The tool used should have the right length so that it can get to the lock.

Step 1: Pry the window using the plastic wedge. The plastic wedge will create a space for putting the airbags.

Step 2: Put the airbags into the space created by the plastic wedge. Once the airbag is in position, inflate the airbag by pressing the pump. Ensure that the airbag is in a good position before inflating it.

Ideally, for maximum performance, ensure you insert it halfway or three-quarters of it depending on the space.

Putting the hydraulic pressure on the airbag is aimed at creating a gap that is enough to insert the pole stick in this case, the Remote Control Button Master.

Using air wedges is ideal because they do not damage the car door. Tweak the air wedges to ensure they are in a good position.

Remember to tighten the airbags every time you tweak them.

Once you have created enough space, this is where the Remote Control Button Master comes in.

When the air wedges are in position, remove the plastic wedges, and tighten the airbags by inflating them more.

This will create a bigger gap.

If your car has vertical manual locks or automatic locks, try to go for either of them.

Step 3: The Remote Control Button Master has a cable and a noose which you can both control using the handle. Fudge in the Remote Control Button Master through the gap and find the right angle.

The curvature of the noose allows you to hook the vertical doorknob of your GMC Sierra. You can tighten the noose to get a better grip of the doorknob.

Step 4: Once you have ensured the noose has a tight grip on the doorknob, simply pull up and poof! The door will be unlocked.

Step 5: Remove the cable and the airbags out of the door to relieve any pressure on the door latch. You can now open the door. Easy, right?

Technique 2:

Technique 2


  • Dental floss

Disclaimer: This technique you can only use to unlock the GMC Sierras with vertical doorknobs.

Step 1: Take out a nice section of the dental floss. The dental floss should be long enough because it has to go in flat into the knob.

Step 2: Tie a slip knot.

Here is a quick rundown of how to tie a slip knot.

First, identify the middle part of the dental floss. The way to do this is to grab both ends and put them together.

Go to the other end and put the middle of the loop and from there grab the back part of the dental floss and loop around the first part of the dental floss.

Grab with your thumb and then grab the back part of the dental floss and tie it together.

Make sure you tighten the knot. You should have a nice slip knot.

Step 3: Locate the rubber guard and the roof of the car. Pass the knot in between the two. This should be fairly easy because dental floss is very thin.

It can easily navigate through the tiny space left by the locked door.

Carefully work the dental floss down by grabbing the two ends like the way you floss your teeth.

Slowly maneuver and manipulate the dental floss to move the knot into position.

By moving both ends, the knot moves in a circular motion making it easy to put it into position. This is the part that needs the most patience and practice.

Make sure the slip knot gets to the doorknob.

Step 4: Once you successfully get the loop into the lock, pull both ends to tighten the loop.

Tighten as hard as you can because the more grip, the easier it will be to open the lock.

Step 5: Once the slip knot has tightly held the doorknob, all you need to do is pull up and the door will be unlocked.

This might not work straight up so you need to be patient. The trick is to keep trying even when the dental floss slips.

Try it a couple of times and you’ll surely hack it.

The secret of hacking this technique is knowing how to tie a slip knot so be sure to familiarize yourself with that first. This technique can only work if you tie the slip knot properly.

Technique 3 :

This technique is ideal for the GMC Sierra door that has a grab handle in the inside.


  • Wedge
  • Pole stick

Step 1: Jam a wedge into the doorpost. Be careful not to rip the window or the door gasket. Make sure the wedge goes through behind the door gasket so that it does not rip it off.

If you insert the wedge well, you should have enough space to insert the pole stick.

Step 2: Take the pole stick and carefully sneak it in through the gap. Maneuver the pole stick in position to ensure it finds the door lock.

Step 3: Once the pole stick has grabbed onto the handle, pull it and you will hear the lock pop open.

Step 4: Be sure to hold on to the pole stick and the wedge because the door will pop open rather quickly since you have wedged it open. Slowly open the door.

And these are the three techniques to enable you to get into your car once you have locked the keys.

However, the best solution is to have a spare key magnetically attached to the car somewhere or keep a spare key in your wallet.

That way you don’t have to go through all these troubles. Fundamentally, all these techniques are founded on one basis; pry the window frame open, reach in and unlock the power door locks.

However, these techniques are not as easy as in the movies. For some reason, movies always have a way of depicting things and making them look a little too simple.

Without the right tools and an understanding of the locking mechanism, it might get frustrating. So practice and master these techniques.

So the next time you lock your keys in the car, try out one of these techniques and see how it goes.
