|---|---|
| Standard Key Fob | Basic design, one or two buttons |
| Proximity Key Fob | Touch-sensitive buttons, keyless entry |

Removing the Old Battery
With the key fob disassembled, you’ll now have access to the battery compartment. Here’s a step-by-step guide on removing the old battery:
1. Locate the Battery
In most Chevy key fobs, the battery will be located in a small compartment within the fob. Look for a small latch or button that you can press to release the compartment.
2. Open the Compartment
Once you’ve located the latch, press it down and slide the compartment open. You may need to use a small screwdriver or prying tool to gently pry the compartment open.
3. Identify the Battery
Once the compartment is open, you’ll see the battery inside. It will likely be a small, round or coin-shaped battery, typically a CR2032 or CR2025. Note the orientation of the battery, as it needs to be reinserted in the same direction.
4. Remove the Battery
Using a small screwdriver, gently pry the battery loose from its compartment. Be careful not to damage the battery or the contacts inside the compartment.
5. Check for Corrosion or Damage
Before inserting the new battery, inspect the battery compartment and the old battery for any signs of corrosion or damage. If you find any corrosion, clean it gently with a cotton swab dipped in isopropyl alcohol. If the old battery is damaged or leaking, dispose of it properly and replace it with a new one.
| Battery Type | Chevy Vehicles |
|---|---|
| CR2032 | 2014-2021 Silverado 1500 |
| CR2025 | 2015-2020 Tahoe |
Testing the Key Fob
Before assuming that a dead battery is the issue, test the key fob to confirm. Perform the following steps:
1. Proximity Test
Stand close to your vehicle and press the lock or unlock button on the fob. If the vehicle responds, the issue may not be the battery.
2. Keyless Entry
Hold the key fob against the door handle and touch the unlock sensor. If the door unlocks, the battery is likely not dead.
3. Visual Inspection
Examine the fob for any visible damage or corrosion. If found, the issue may be with the fob’s circuitry rather than the battery.
4. Alternative Fob
If you have a spare key fob, try using it instead. If the spare works, the problem may lie with the original fob.
5. Radio Frequency Interference
Move away from potential sources of radio frequency interference, such as cell towers or Wi-Fi routers. If the fob then works, the interference may have been causing the issue.
6. Resynchronize the Fob
Follow the vehicle’s user manual to resynchronize the key fob with the car. If this resolves the problem, the fob may have lost its connection with the vehicle.
7. Diagnostic Scan
Take your car to a mechanic for a diagnostic scan. They can use special equipment to pinpoint the cause of the key fob malfunction.
8. Battery Health Check
If all else fails, remove the battery from the fob and check its voltage using a multimeter. A reading of less than 2.9 volts indicates a dead battery. Refer to the table below for battery specifications specific to different Chevrolet models:
| Model | Battery Type | Voltage |
|---|---|---|
| Silverado 1500 | CR2032 | 3V |
