How To Start GMC Acadia With Key Fob

One of the most convenient features of owning a GMC Acadia is the ability to remotely start the vehicle with a key fob. On cold winter mornings, nothing feels better than climbing into a warm, cozy cabin without having to get into the driver’s seat right away. As someone who hates how cold leather seats get in the winter, being able to start GMC Acadia with key fob from inside my home has been a real game changer.

Understanding Your Key Fob

The first step is understanding the key fob that came with your GMC Acadia. The fob allows you to remotely start GMC Acadia with key fob from outside the vehicle. It should have two buttons – one to lock the doors and one to unlock them. It may also have a button to pop the rear hatch or liftgate open.

The most important button is the one used to start GMC Acadia with key fob. It’s typically a button on the fob that has an image of an engine or car on it. To start GMC Acadia with key fob, you’ll press this button while standing outside near the vehicle.

Checking Your Owner’s Manual

If you’re unsure which button on the key fob starts the Acadia, double check your owner’s manual. The manual provides all the details on the key fob functions and how to properly start GMC Acadia with key fob. It will call out exactly which button to press and the range it works at.

Following the instructions in the manual is super important. Otherwise, you may press the wrong button and wonder why it’s not working! The manual is your best friend for learning everything about your specific Acadia model.

Ensuring The Key Fob Battery is Good

For the key fob to work and allow you to start GMC Acadia with key fob, the battery inside needs to be in good shape. As time goes on, batteries can weaken and die. If your fob seems flaky or unresponsive, replace the battery.

You can find replacement cr2032 or cr2025 batteries at most stores like Walmart, Target, or AutoZone. Swapping the battery only takes a few minutes. With a fresh one, your fob will have no problem letting you start GMC Acadia with key fob.

Checking The Vehicle Settings

Some Acadias have settings that need to be enabled for keyless entry and remote start. So before trying to start GMC Acadia with key fob, log into your Uconnect system and check the settings.

Look for options related to “Remote Start” or “Remote Keyless Entry”. Make sure these features are turned on. The settings may also specify how long the engine will run, temperature thresholds, and more. Tweak them as needed.

Practicing With The Key Fob

Once you understand your key fob and verified the settings and battery, it’s time to practice using it to start GMC Acadia with key fob. Stand outside the vehicle, but within range of the key fob transmitter, which is usually 30 feet or so.

Press and hold the designated start button. You should hear a chirp from the Acadia acknowledging the signal. Then, after a couple seconds, the engine should turn over and start up. If it doesn’t, don’t worry – keep practicing until you get the timing down.

With some trial and error, you’ll become a pro at being able to start GMC Acadia with key fob from a distance. It’s so handy during cold mornings so the interior can warm up while you finish getting ready.

Final Thought

Can I start my Acadia if the key fob battery is low?

If the key fob battery is very low, it may not have enough power left to send the signal to start the vehicle remotely. You’ll want to replace it before trying again. However, you can still use the physical key portion of the fob to unlock and start the Acadia manually.

What’s the range of the key fob transmitter?

Most Acadia key fobs have an effective range of about 30 feet. However, this can vary depending on your exact model year and any obstructions between the fob and vehicle. As a general rule, stand closer than 30 feet if it’s not working at the maximum distance. Line of sight is best but walls/objects shouldn’t block it within 30 feet.

Can two vehicles be started at once with two fobs?

No, the remote start system can only recognize one signal at a time. If you and your partner both tried starting your separate Acadias remotely at the exact same moment, it may cause interference and neither would work. Take turns or stagger the start times slightly to avoid any issues.

Is it bad to leave my car running with the remote start?

It’s perfectly fine to let your Acadia run for a period of time when remote started. In fact, that’s the whole point! The manufacturer has set safe run time limits, usually 10-15 minutes. Just don’t forget and leave it running indefinitely unattended. Be sure to return to the vehicle before the engine automatically shuts off.

What if my key fob gets wet – will it still work?

If your key fob gets exposed to moisture, it’s best to wipe it dry as soon as possible. Water can seep into the fob casing and potentially impact performance or even cause damage over time. The fob may still work when wet but signals could be weaker. Once dry, it should function normally again for remote starting the Acadia.
