What is GMC Sierra passive door locking?
Passive door locking is a great feature for those that are sometimes forgetful in locking their vehicle's doors. If you walk away from your GMC Sierra without locking the doors yourself, the car will automatically lock the doors on its own after several minutes.
Several conditions must be met for the passive door locking feature to work before your Sierra will auto-lock. The Sierra cannot be left running; the sensor detects a running engine and will not activate for safety reasons. This is important to remember if you're thinking about starting your Sierra on a cold day and letting it warm up while you run back inside your warm house. It'll still be running AND unlocked unless you manually lock the doors.
All of the doors to your Sierra have to be firmly closed for the passive locking system to auto-lock. Your control panel should indicate if any doors are still open, should the ignition key be still switched to the on position. Before exiting your Sierra, make sure no doors are left open.
The passive door locking feature will also not lock the doors if you leave your key fob in your Sierra. This is to make sure you don't accidentally lock yourself out of your vehicle.
Can you disable the automatic door locking?
If you would like to disable the automatic door locking feature, there is a simple way to temporarily shut it off. Simply stand near your closed, locked Sierra and hold the "unlock" button on your key fob for a few moments. When you hear a series of beeps from your Sierra, then you'll know that the automatic door locking has been paused. This auto-locking will remain disabled until you hit the lock button on your truck's interior door or when you start the Sierra's engine.
Your Sierra's owners' manual will assist you in permanently disabling the automatic door locking feature, beginning on page 167. You'll be guided through how to "Personalize Your GMC Sierra" here. On your infotainment screen, select the settings button, then press the button indicating the vehicle. You'll then see a list of features. Select the passive door locking feature and hit the "disable" button. Your automatic door locking will now be disabled unless you turn it back on, using the same steps.
How to prevent getting locked out of my truck?
The best way to prevent getting locked out of your Sienna is always to make sure that your key fob is in your hand before you walk away from your truck, and making a habit out of always keeping the key fob or keys in the same place.
Undercarriage magnetic boxes used to be a great place to store an extra key fob or key, although some vehicle thieves have gotten wise to this over the years. The technology and design of these have greatly improved, though, with many on the market boasting of "waterproof" boxes with super strong magnets. These seem to be great for stashing a mini GPS device inside, also, in case your Sierra gets stolen.
