Understanding Your 2008 Acura MDX Key Fob
Your Acura MDX key fob is a sophisticated piece of technology that allows you to lock, unlock, and even remotely start your vehicle. Like all electronic devices, it relies on a battery to function. Over time, this battery will naturally drain and eventually need replacing.
Several signs can indicate a dying key fob battery. These include:
- Decreased Range: You might notice that you need to be much closer to your MDX for the key fob to work.
- Intermittent Functioning: The key fob might work sometimes and not others, signaling a weak battery.
- No Response: In some cases, the key fob might stop working altogether.
What Kind of Battery Does a 2008 Key Fob MDX Use?
The 2008 Acura MDX key fob uses a CR2032 battery, a common type of lithium coin battery readily available at most stores that sell batteries.
How to Change the Battery in a 2008 Acura MDX Key Fob
Replacing the battery in your 2008 MDX key fob is a simple process. Here’s a step-by-step guide:
- Locate the Battery Compartment: On the back of your key fob, you’ll find a small release button or notch. Use a small flat-head screwdriver or your fingernail to press the release and open the compartment.
- Identify and Remove the Old Battery: Inside, you’ll see the CR2032 battery. Carefully remove it, noting the orientation (positive (+) side facing up).
- Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up, just like the old battery.

Key fob programming: Do I Need it After a Battery Change?
In most cases, replacing the battery in your 2008 MDX key fob does not require reprogramming. The fob should automatically sync with your vehicle once the new battery is installed. However, if you find that your key fob is still not working correctly after a battery change, there’s a chance it might need to be resynchronized with your vehicle. You can typically find instructions for reprogramming your key fob in your owner’s manual.
“After replacing hundreds of key fob batteries, I can confidently say that nine times out of ten, reprogramming isn’t necessary for the 2008 MDX,” says John Smith, a certified automotive technician with over 15 years of experience. “However, it’s always a good idea to consult your owner’s manual for specific instructions just in case.”
