Modern car key fobs are incredibly convenient, allowing for keyless entry, remote start, and a host of other features. However, these smart devices rely on batteries, and like all batteries, they eventually need replacing. If you own a 2016 Acura RDX, understanding how to maintain your key fob, including replacing its battery, is essential for ensuring seamless vehicle operation.
The 2016 Acura RDX, as highlighted in its official press kit, comes equipped with a sophisticated Keyless Access System with Smart Entry and Remote Engine Start. These features enhance convenience and luxury, but they are all powered by the key fob’s battery. Knowing when and how to replace this battery can save you from unexpected inconveniences.

Key Fob Features of the 2016 Acura RDX
The 2016 Acura RDX key fob is more than just a key; it’s a command center for your vehicle. According to the press kit, the Keyless Access System allows you to unlock your RDX simply by pulling the door handle while the fob is in your possession. This system recognizes a unique digital identity for each fob, and can even automatically adjust settings like seat position, mirrors, climate control, and audio preferences based on which fob is detected.
Furthermore, the Remote Engine Start feature, standard on the Advance Package, allows you to start your RDX from a distance of up to 328 feet. This is incredibly useful for pre-heating or cooling your vehicle before you even step inside. The press kit also mentions a “quick vent” feature activated via the key fob, which lowers windows and opens the moonroof to vent hot air.

Why Your 2016 Acura RDX Key Fob Battery Will Need Replacing
Key fob batteries, typically small coin-cell batteries, have a limited lifespan. Several factors contribute to battery depletion in your 2016 Acura RDX key fob:
- Usage Frequency: The more frequently you use your key fob – locking/unlocking doors, using remote start, panic button etc. – the faster the battery will drain.
- Signal Strength: Constantly transmitting signals to and from your vehicle consumes battery power.
- Environmental Factors: Extreme temperatures, both hot and cold, can affect battery life.
- Battery Age: Like all batteries, key fob batteries degrade over time, even if unused.
The 2016 Acura RDX press kit mentions a “Built-in Key” within the remote fob as a backup, and a “remote battery is low” warning displayed on the Multi-Information Display (MID). This warning is your signal that the key fob battery is nearing the end of its life and should be replaced soon. Ignoring this warning can lead to your key fob becoming unresponsive, leaving you unable to remotely lock/unlock or start your vehicle.
How to Replace the 2016 Acura RDX Key Fob Battery: A Step-by-Step Guide
While the 2016 Acura RDX press kit doesn’t provide specific instructions on key fob battery replacement, the process is generally straightforward for most modern key fobs. Here’s a general guide. Always refer to your 2016 Acura RDX owner’s manual for the most accurate and model-specific instructions.
Step 1: Identify the Battery Type
Consult your owner’s manual to determine the correct battery type for your 2016 Acura RDX key fob. Common key fob batteries are CR2032, CR2025, or CR1632. Using the wrong battery type can prevent your key fob from working correctly.
Step 2: Open the Key Fob Casing
Most key fobs have a small release button or latch that allows you to open the casing.
- Locate the Release: Look for a small button or a sliding latch on the key fob.
- Release the Emergency Key (If Applicable): Some key fobs require you to first remove the physical emergency key. This is usually done by sliding a small release.
- Open the Casing: Once the release is activated, you may need a small flathead screwdriver or a coin to gently pry open the key fob casing. Be careful not to scratch or damage the plastic. Some fobs may simply pull apart once the release is activated.
Step 3: Remove the Old Battery
- Note the Battery Orientation: Pay close attention to how the old battery is positioned in the compartment (+ and – sides). You’ll need to insert the new battery in the same way.
- Remove the Battery: Gently pry out the old battery. A small flathead screwdriver can be helpful here, but be careful not to damage the battery compartment or any internal components.
Step 4: Install the New Battery
- Insert the New Battery: Place the new battery into the compartment, ensuring the correct orientation (+ and – sides match the markings in the compartment or how the old battery was positioned).
- Secure the Battery: Make sure the battery is firmly seated in its place.
Step 5: Close the Key Fob Casing
- Reassemble the Casing: Carefully snap the key fob casing back together until it is securely closed. Ensure all parts are aligned properly.
- Test the Key Fob: Test all the buttons on your key fob – lock, unlock, remote start, panic button – to confirm the new battery is working correctly.
