When your key fob starts acting up—requiring closer proximity to the car to function—it's a clear sign the battery is fading. Don't wait until it completely dies; replace it promptly. Then, you’ll be opening the Car Key Fob. Most car key fobs can be easily opened to access the battery compartment. Depending on your model, you may need to pry off the back using your fingers or a screwdriver. Some fobs require flipping out a physical key or sliding out a hidden backup key first. Before removing the old battery, ensure you have a replacement ready. If the fob is left without power for too long, reprogramming might be necessary. Refer to your car's manual for DIY reprogramming instructions or seek assistance from the Contact the Remote Pro Team if needed. Typically, car key fobs utilise flat round batteries like the CR2032.
