Dead Key Fob Battery: 2024 Chevy Equinox (US) — How to Get Back In and Start

If your 2024 Chevrolet Equinox key fob suddenly won’t lock/unlock or the vehicle won’t detect the fob, the most common cause is a dead fob battery. The good news: you can still get into the Equinox and start it using the built-in backup methods, then replace the battery.

Understanding Your Situation

The coin-cell battery inside the Equinox key fob has weakened or died, so the fob can’t transmit a strong enough signal for keyless entry and push-button start detection. The vehicle’s backup mechanical key and emergency start procedure can still work even when the fob battery is dead.

🚀 Immediate Steps to Take

  1. Use the mechanical key inside the fob to unlock the driver’s door (look for the key release on the fob, then use the hidden key cylinder on the door handle area).
  2. To start, place the fob in the designated backup location (often the center console pocket/cupholder area or as shown in the owner’s manual) and then press the brake and push the START/STOP button.
  3. Replace the fob battery with the correct type (commonly CR2032 on many GM fobs, but confirm your exact fob/owner’s manual), ensuring the battery is seated correctly and the fob halves snap back together fully.

Your Options

DIY key fob battery replacement (most common fix)

Cost: $3-$12 Time: Same day

Open the fob case, replace the coin-cell battery with a new, name-brand cell, and reassemble. Test lock/unlock and remote start (if equipped).

✓ Pros:
  • Lowest cost
  • Fast and widely available (pharmacies, big-box stores, auto parts stores)
✗ Cons:
  • Easy to damage the fob housing if pried incorrectly
  • Wrong battery type or upside-down install can make it seem like the fob is still dead

Battery replacement at a dealership or repair shop

Cost: $0-$30 Time: Same day

A service advisor/technician replaces the key fob battery and verifies the fob functions properly with the vehicle.

✓ Pros:
  • Minimal effort; reduced chance of breaking the fob
  • They can confirm whether the issue is battery-related or something else
✗ Cons:
  • May require an appointment or wait time
  • Higher cost than DIY (unless performed as a courtesy)

Mobile locksmith or roadside assistance (if you’re locked out or stranded)

Cost: $60-$180 Time: Same day

A provider helps you enter the vehicle and/or get it started using proper procedures; they may also replace the fob battery if available.

✓ Pros:
  • Helpful if you can’t access the mechanical key method or you’re away from home
  • Can confirm if the problem is truly the fob battery
✗ Cons:
  • More expensive than a battery
  • Service availability and arrival times vary

Replace the key fob (if battery replacement doesn’t fix it)

Cost: $200-$450 Time: 1-3 days

Purchase a new OEM fob and have it programmed to your Equinox. This is typically needed if the fob is damaged, water-exposed, or internally failed.

✓ Pros:
  • Restores full reliability if the fob itself failed
  • OEM fobs typically provide best compatibility
✗ Cons:
  • Highest cost option
  • Programming may require dealer/qualified locksmith equipment

⚠️ What to Avoid

✕ Don’t force the door with tools or try to pry windows/trim—damage can cost far more than a battery or locksmith call.

✕ Don’t install a random battery size “that fits”; using the wrong coin cell can cause intermittent operation or poor contact.

✕ Don’t touch both sides of the new battery excessively with bare fingers—skin oils can reduce contact quality; handle by the edges when possible.

⚠️ Common Mistakes to Avoid

  • Using wrong battery type
  • Damaging case during opening
  • Not resetting after replacement
  • Buying expensive batteries

Frequently Asked Questions

Can I start my 2024 Chevy Equinox if the key fob battery is dead?

Yes. Use the vehicle’s backup start method: place the fob in the designated backup location (refer to the owner’s manual for the exact spot), then press the brake and push the START/STOP button. The vehicle can often read the fob via close-range backup detection even with a weak/dead fob battery.

What battery does the 2024 Equinox key fob use?

Many GM key fobs use a CR2032 coin-cell battery, but fob designs can vary by trim/package and production. Confirm the battery type by checking the old battery imprint once opened or referencing your owner’s manual.

Will I lose programming if I change the key fob battery?

No. Replacing the coin-cell battery does not erase the fob’s programming. If the fob still doesn’t work after a new battery, the issue may be a damaged fob, poor battery contact, or a vehicle-side problem.

How do I know it’s the fob battery and not the car battery?

If the vehicle won’t respond to remote lock/unlock and you see reduced range or intermittent operation, it’s often the fob battery. If the vehicle has trouble powering on accessories, cranking, or shows multiple electrical warnings, the 12V vehicle battery could be low. Trying the backup start method can help narrow it down.

⏱️ Urgency Note: Low to moderate urgency: a dead fob battery can leave you locked out or unable to start at the worst time. Replace it soon, and keep a spare coin-cell battery in your glove box or at home.
