Experiencing problems with your 2019 Chevy Impala Key Fob can be frustrating. If your key fob is acting intermittently or not working at all, there are a couple of common issues you can check yourself before seeking professional help. Often, the problem lies within the key fob itself, specifically with the battery or the internal contacts. This guide will walk you through inspecting these components to potentially resolve your key fob troubles.
A frequent culprit behind a malfunctioning key fob is a weak or dead battery. Like any battery, the coin cell battery in your 2019 Chevy Impala key fob has a limited lifespan. To check the battery, you’ll need to carefully open the key fob casing. Once open, you’ll see the battery, typically held in place by small clips or pressure contacts. Ensure the battery is correctly positioned and making good contact with the terminals. It’s also crucial to verify the battery voltage using a multimeter if you have one. A healthy battery should read at least 3.0 volts. If the voltage is lower, replacing the battery is a good first step. Make sure to install the new battery with the “+” side facing upwards, as indicated inside the battery compartment.
Beyond the battery itself, the internal contacts within the key fob are critical for proper function. These contacts, both positive and negative, ensure the electrical connection between the battery and the key fob’s circuit board. Inspect these contacts for any signs of corrosion, dirt, or damage. The positive contacts are often springy fingers that press against the battery, while the negative contact is usually soldered to the circuit board. Make sure these solder points are intact and not cracked, as rough handling can sometimes cause them to break. Clean the contacts gently if you notice any tarnish or debris. A clean contact surface is essential for reliable operation.
If you’ve checked both the battery and the contacts and your 2019 Chevy Impala key fob is still not working correctly, the issue might be more complex, potentially involving the internal circuitry or programming of the key fob. In such cases, purchasing a new key fob and having it programmed to your vehicle by a qualified locksmith or dealership might be necessary. It’s also worth noting that sometimes, if the vehicle’s security system is confused by an intermittent key fob signal, disconnecting and reconnecting the car battery for a short period can help reset the system. While these basic checks can resolve common key fob problems, always consult a professional for more persistent or intricate issues.
