Reasons Why Your Buick Envision Can't Detect The Remote Key 

There are a lot of possible reasons why your Buick Envision can't detect your remote key. You can easily repair some of these issues. But for some, you will need to contact your dealer and have a professional mechanic service your vehicle.

Here are a few of the most common causes of this problem:

Remote Battery Is Dead

A dead remote key battery is one of the most common issues when it comes to your remote key not working. Luckily, you can resolve this issue with just a quick battery replacement.

Buick Envision's remote keys use a CR 2032 battery to power the remote on older models. This type of battery is pretty common and you can purchase this at your local store or on Amazon.

Check out these Energizer CR 2032 batteries on Amazon.

For recent Buick Envision models, however, the remote key uses a CR 2450 battery as a power source. This type of battery is also pretty common and is available everywhere.

How To Replace The Battery On Your Remote Key

The battery replacement of your remote key will depend on your Buick Envision model. Make sure to follow the correct procedure for your model type to reduce the risk of damaging your remote key.

  1. Press the button on the back of the remote key to release the spare mechanical key.
  2. Separate the two halves of the remote key using the spare mechanical key or any flat tool inserted into the bottom portion of the remote key.

Replacing A Broken Remote Key

We use our vehicles almost every single day. This also means that we tinker with the remote key at the same amount of time. Using the remote key regularly can cause knicks and scratches that could lead to issues and, eventually, permanent damage to the remote itself.

The safest and most efficient method when you need a replacement remote key is to order directly from the vehicle manufacturer. This guarantees that the remote key replacement you will receive is of genuine quality and not some cheap knockoff.

You may contact your local Buick dealer for remote key replacements. You may also contact the customer support division of Buick so they can assist you with the replacement.

A Weak Car Battery

Your car's battery provides enough electricity to power up your car. This includes critical engine parts and electronics.

When your car's battery becomes weak, it can cause problems such as preventing your car from cranking up, leaving you stranded. It can also be a reason why your remote key cannot be detected.

Luckily, there is one sure-fire way in which you can diagnose this problem. A battery test. A simple battery check can prevent you from being stranded somewhere and it will also save you costs in the future. This will also help you determine if you need a battery replacement or just a simple engine jump start.

How To Perform A Battery Test

Checking regularly your car batter to avoid inconvenience  

You can test the battery output of your vehicle by using a standard multimeter. This can be purchased from your local auto store or through Amazon.

Check out this multimeter on Amazon.

To perform the battery test, follow these steps.

  1. Make sure the vehicle is off. Turn on headlights for about two minutes to remove any surface charge that could affect the reading.
  2. Prepare your multimeter and set it to the nearest unit above 15 volts. Turn off the headlights after two minutes.
  3. Connect the red rod to the positive lead on your battery (usually red-colored) and the black rod to the negative lead (usually black-colored).
  4. Wait for the reading. The ideal voltage reading should be around 12 to 13 volts.
