2024 Chevy Equinox Key Fob Not Working? Fixes, Costs, and What to Do Now

If your 2024 Chevrolet Equinox key fob suddenly won’t lock/unlock the doors or allow push-button start, the cause is often a weak battery, signal interference, or a fob/vehicle communication issue. The good news: most problems can be diagnosed in minutes and fixed the same day.

Understanding Your Situation

The Equinox key fob communicates with the vehicle via radio signals for remote lock/unlock and via proximity/low-frequency systems for Passive Entry/Push-Button Start. When the fob battery is weak, the signal is blocked/interfered with, or the fob loses synchronization (or fails), the car may not respond or may display a “No Remote Detected” type message.

🚀 Immediate Steps to Take

  1. Try the backup start method: hold the fob against the designated backup location (often in the center console/cupholder area—check your owner’s manual) and then press the brake and START/STOP. This can work even with a weak fob battery.
  2. Replace the key fob battery with a quality coin-cell (commonly CR2032 on many GM fobs, but confirm for your exact fob). After replacement, test lock/unlock and remote start (if equipped).
  3. Rule out interference and range issues: move away from other electronics/metal structures, try the fob right next to the driver door, and try your spare fob. If only one fob fails, the issue is likely the fob; if both fail, it may be the vehicle receiver/module or settings.

Your Options

Replace the key fob battery (DIY)

Cost: $5-$15 Time: Same day

Open the fob case carefully, install the correct new coin-cell battery, and verify all functions (lock/unlock, remote start if equipped, and push-button start proximity).

✓ Pros:
  • Fast and inexpensive
  • Fixes the most common cause of intermittent or sudden failure
✗ Cons:
  • Wrong battery type or low-quality cells can cause repeat issues
  • Doesn’t help if the fob is damaged or the vehicle has a receiver/module problem

Use the spare fob and isolate the problem

Cost: $0 Time: Same day

Test the spare key fob from multiple locations. If the spare works normally, the original fob likely needs a battery, repair, or replacement. If neither works, the issue is more likely vehicle-side (receiver, antenna, settings, or power issue).

✓ Pros:
  • Quick diagnostic step
  • Helps avoid unnecessary parts or programming
✗ Cons:
  • Not possible if you don’t have a spare
  • Doesn’t fix the underlying issue by itself

Replace/repair the key fob (shell, buttons, or full fob)

Cost: $60-$350 Time: Same day / 1-3 days

If the fob has been dropped, exposed to moisture, or buttons are worn, you may need a new fob housing or a full replacement fob. A replacement fob typically requires programming to the vehicle.

✓ Pros:
  • Restores reliability if the fob is physically failing
  • Can be a permanent fix when battery replacement doesn’t help
✗ Cons:
  • Programming may be required and adds cost
  • Aftermarket fobs vary in quality and compatibility

Dealer diagnosis and programming (GM/Chevrolet)

Cost: $150-$500 Time: Same day / 1-3 days

A Chevrolet dealer can test the fob, check for vehicle-side faults (receiver/BCM-related issues), update software if applicable, and program new keys/fobs to your Equinox.

✓ Pros:
  • Highest compatibility and correct programming
  • Can address vehicle-side causes, not just the fob
✗ Cons:
  • Typically the most expensive route
  • May require an appointment and proof of ownership

Automotive locksmith (mobile) programming and replacement

Cost: $120-$350 Time: Same day

A qualified automotive locksmith can often supply and program a compatible fob on-site and diagnose basic communication issues. Availability depends on your area and vehicle configuration.

✓ Pros:
  • Often faster and less expensive than a dealer
  • Convenient mobile service (helpful if you’re stranded)
✗ Cons:
  • Not all locksmiths can service every 2024 model/configuration
  • Aftermarket fob quality can vary

⚠️ What to Avoid

✕ Avoid repeatedly forcing the fob case open with metal tools that can crack the housing or damage the internal board—use a plastic pry tool if possible.

✕ Avoid buying the cheapest unverified fob online; incorrect FCC/part numbers or poor-quality units can fail to program or work intermittently.

✕ Avoid leaving a weak-battery fob in the vehicle or very close to it for long periods—constant proximity communication can drain the battery faster.

⚠️ Common Mistakes to Avoid

  • Assuming key is broken
  • Not checking battery first
  • Calling tow truck immediately
  • Replacing when reprogramming needed

Frequently Asked Questions

My 2024 Equinox says “No Remote Detected.” Can I still start it?

Often, yes. Try the backup start method by placing/holding the fob at the designated backup location (commonly the center console/cupholder area—confirm in your owner’s manual), then press the brake and START/STOP. This is designed to work even when the fob battery is weak.

If the key fob locks/unlocks but won’t remote start, what does that mean?

Remote start can be blocked by conditions like low fuel, a check engine light, certain security states, doors/hood not fully closed, or HVAC/temperature-related limits—depending on configuration. Also check the fob battery and try the spare fob; remote start typically needs a stronger, consistent signal than basic unlock at close range.

Do I need to reprogram the fob after changing the battery?

Usually no. A battery change typically does not erase programming. If the fob still doesn’t work after a correct new battery, the fob may be damaged, incompatible, or the vehicle may have a receiver/module issue that needs diagnosis.

Why does my key fob work only when I’m very close to the car?

That’s a classic sign of a weak fob battery, but it can also be radio interference or a damaged fob antenna/circuit board. Replace the battery first, then test in different locations and compare with the spare.

⏱️ Urgency Note: If you’re unable to start the vehicle or the fob is lost and you’re down to one working key, address it promptly. Waiting can leave you stranded and can increase cost if all keys are lost (programming and recovery is typically more involved).
