How to Replace Your Chevrolet SS Key FOB Battery
Replacing your Chevrolet SS key fob battery is a straightforward process, but doing it correctly ensures longevity and prevents damage.
The key fob uses a CR2032 lithium coin battery, which typically lasts 2-4 years depending on usage. Below, we break down the step-by-step process with expert tips to avoid common mistakes.
Step 1: Open the Key Fob Housing
Most Chevrolet SS key fobs have a small release notch on the side. Insert a flathead screwdriver or a plastic pry tool into this slot and gently twist to separate the two halves. Avoid using excessive force—this can crack the casing or damage internal components. If your key fob has a hidden key blade, remove it first to prevent accidental damage.
Step 2: Remove the Old Battery
Once opened, locate the circular battery compartment. The CR2032 battery is held in place by a small metal clip. Use a non-metallic tool (like a plastic spudger) to pop the battery out, preventing short circuits. Note the battery’s orientation (+/-) before removal—this ensures proper reinstallation.
Step 3: Install the New Battery
Insert the new CR2032 battery with the positive (+) side facing up (unless otherwise indicated). Press it firmly into place until it clicks. Avoid touching the battery’s surface with bare fingers—oils from your skin can reduce conductivity. Wipe the contacts with a dry cloth if corrosion is present.
Step 4: Reassemble and Test
Align the key fob halves and snap them together. Test all buttons (lock, unlock, trunk release) within 10 feet of your car. If any function fails, reopen the fob and double-check the battery’s placement.
Pro Tips to Extend Battery Life
- Avoid extreme temperatures: Heat accelerates battery drain, while cold can temporarily reduce voltage output.
- Minimize unnecessary button presses: Repeated signals (like panic alarms) drain power faster.
- Store spare fobs properly: Keep them in a Faraday pouch to prevent constant signal transmission.
If your key fob still doesn’t work after replacement, check for deeper issues like damaged contacts or water intrusion. A dealership can reprogram the fob if needed.
Troubleshooting Common Chevrolet SS Key FOB Issues
Even after replacing the battery, your Chevrolet SS key fob might still malfunction. Understanding these common issues and their solutions can save you time and frustration. Below we explore the most frequent problems and professional fixes.
Key Fob Not Responding After Battery Replacement
If your key fob remains unresponsive, first verify the battery is installed correctly. The CR2032 must sit flush with the contacts—even a slight misalignment can prevent operation. Try these steps:
- Check polarity: The positive (+) side should face upward unless your fob’s manual states otherwise.
- Clean contacts: Use isopropyl alcohol and a cotton swab to remove oxidation from the battery terminals.
- Reset the fob: Remove the battery for 30 seconds, then reinsert it to reboot the circuit.
Intermittent Functionality or Weak Signal
A fob that works sporadically often suffers from:

Frequently Asked Questions About Chevrolet SS Key FOB Batteries
What type of battery does my Chevrolet SS key fob use?
The Chevrolet SS uses a standard CR2032 3V lithium coin battery. This battery type was chosen for its stable voltage output and 10-year shelf life. Always purchase name-brand batteries (Energizer, Duracell, or Panasonic) as off-brands may have inconsistent performance.
For 2014-2017 models, the battery is inserted positive-side up. Some aftermarket fobs may require different orientation – check your manual. The battery typically lasts 2-3 years with normal use.
How do I know when my key fob battery is dying?
Early warning signs include reduced operating range (needing to be closer to the car), delayed response, or intermittent functionality. The vehicle may display a “Key FOB Battery Low” message on the dash for later model years.
Advanced symptoms include the panic button working while lock/unlock doesn’t, or the remote start failing first. These occur because different functions require varying power levels.
Can a dead key fob battery prevent my car from starting?
Yes, but only if your SS has push-button start. The passive entry system requires fob power to authenticate. For traditional ignition models, you can still start the car by inserting the physical key, even with a dead fob battery.
If stranded, hold the fob against the steering column while pressing start – this uses NFC backup power. The exact spot varies by model year but is typically near the ignition cylinder.
Why does my new battery drain quickly?
Rapid drainage suggests either a defective battery (common with cheap brands) or a stuck button causing constant transmission. Inspect the button contacts for debris or worn silicone pads that might prevent full release.
Less common causes include water damage creating shorts, or a malfunctioning vehicle receiver constantly polling the fob. Professional diagnosis requires measuring standby current draw (should be under 5μA).
Is it safe to replace the battery myself?
Absolutely, with proper precautions. Use plastic tools to avoid shorting contacts, and never force the casing open. The main risk is damaging the waterproof seals – apply a thin silicone grease when reassembling.
Avoid touching the battery contacts with bare fingers. Skin oils can corrode the contacts over time. Always check button responsiveness before final reassembly.
How do I reprogram my key fob after battery replacement?
Most Chevrolet SS fobs don’t require reprogramming after battery changes. If functions stop working, try this reset: With the car off, press and hold both lock and unlock buttons for 15 seconds while standing next to the vehicle.
For models requiring full reprogramming, you’ll need a Tech2 scanner or dealership visit. The process involves a 30-minute security handshake with the BCM module.
What’s the difference between OEM and aftermarket batteries?
Genuine GM batteries (part # 13537571) have stricter quality control and military-grade sealing. However, premium aftermarket brands often exceed OEM specifications – look for 220mAh capacity or higher.
Key differences include: OEM batteries use brass contacts instead of steel, have thicker lithium layers, and undergo vibration testing. For most users, high-quality aftermarket batteries work fine.
Can extreme weather affect my key fob battery?
Yes. Cold below -20°F can temporarily reduce voltage output by 30%, while heat above 140°F accelerates chemical degradation. The battery compartment isn’t thermally insulated like the car’s receiver.
In harsh climates, consider using industrial-grade batteries like the Energizer L92BP-4, rated for -40°F to 140°F. Store spare fobs in temperature-controlled environments.
