Damaged Key Fob for a 2024 Chevy Traverse: What to Do Next

A damaged key fob can leave your 2024 Chevrolet Traverse unreliable to unlock, start, or remote-start—especially if the buttons, case, or internal board are affected. The right next step depends on whether the fob still works, was exposed to water, or is physically broken.

Understanding Your Situation

The key fob may be cracked from a drop, have stuck or non-responsive buttons, or have internal damage from moisture. Even if it still works intermittently, damage can worsen quickly and may lead to a no-start/no-unlock situation.

🚀 Immediate Steps to Take

  1. Check if the Traverse still unlocks/locks and starts; if the fob is swollen, hot, or smells burnt, stop using it and keep it away from flammables.
  2. If the fob got wet: remove it from your key ring, dry the exterior, and place it in a dry, ventilated area; avoid charging or pressing buttons repeatedly. If you can safely open the case, remove/replace the battery after drying.
  3. Use your spare fob if available and schedule service for repair/replacement before the damaged fob fails completely.

Your Options

Replace the key fob battery (if the fob is intact)

Cost: $5-$15 Time: Same day

If the case and buttons are fine but range is weak or operation is intermittent, a fresh coin-cell battery may restore normal function. Battery replacement will not fix water intrusion or a cracked circuit board.

âś“ Pros:
  • Lowest-cost first step
  • Can immediately restore range and reliability if the issue is only a weak battery
âś— Cons:
  • Won’t fix physical or water damage
  • Opening a damaged case can break clips or compromise sealing further

Swap to a new key fob shell/case (reuse internal electronics)

Cost: $15-$60 Time: Same day / 1-3 days (shipping dependent)

If the plastic housing, buttons, or key ring loop is broken but the electronics still work, you can move the internal circuit board and battery into a new shell. This is a physical repair only—no programming if the original electronics are reused.

âś“ Pros:
  • Often restores usability after drops/cracks
  • Usually avoids programming costs when reusing the original board
âś— Cons:
  • Not suitable if the circuit board or contacts are damaged
  • Wrong shell style can cause poor button feel or misalignment

Professional key fob replacement and programming (dealer or automotive locksmith)

Cost: $200-$500 Time: Same day / 1-3 days

Replace the entire fob with a new OEM or high-quality aftermarket unit and program it to your 2024 Traverse. This is the most reliable option when the fob has water damage, internal failure, or severe physical damage.

âś“ Pros:
  • Most reliable fix for internal or moisture damage
  • Can restore full functions (lock/unlock, remote start if equipped, etc.)
âś— Cons:
  • Highest cost
  • May require the vehicle present and proof of ownership; scheduling delays possible

Electronics repair service (board-level repair when replacement is costly)

Cost: $60-$180 Time: 3-10 days

A specialty service may attempt to clean corrosion, replace micro-switches, or repair solder joints on the existing key fob circuit board. Best for fobs that are hard to source or when you want to keep the original unit.

âś“ Pros:
  • Can be cheaper than full replacement in some cases
  • May preserve original fob identity and fit/feel
âś— Cons:
  • Not always successful (especially after heavy water exposure)
  • Turnaround time and shipping risk

⚠️ What to Avoid

✕ Don’t microwave, bake, or use a heat gun/hair dryer on high heat—excess heat can warp the case and damage the circuit board or battery.

✕ Don’t keep pressing buttons on a wet or damaged fob; it can worsen corrosion or short the electronics.

✕ Don’t buy an incompatible fob (wrong FCC ID/part type) or assume all “2024 Traverse” fobs program the same—verify compatibility before purchase.

⚠️ Common Mistakes to Avoid

  • Throwing away damaged key
  • Not salvaging electronics
  • Buying OEM when aftermarket works
  • Not considering case-only replacement

Frequently Asked Questions

Can I still start my 2024 Chevy Traverse if the key fob is damaged?

Sometimes. If the fob’s battery is weak or the buttons are broken but the transponder still communicates, the vehicle may still start. If the fob has internal damage (especially water/corrosion), it may fail without warning—use a spare and plan replacement.

Do I have to go to a Chevrolet dealer to replace a damaged key fob?

Not always. Many automotive locksmiths can supply and program compatible fobs for the 2024 Traverse. A dealer is a solid option for OEM parts and warranty support, but a qualified locksmith may be faster or less expensive.

If I replace only the shell, do I need programming?

Usually no. If you move your original circuit board into a new shell, the vehicle still recognizes the same fob electronics, so programming typically isn’t required.

What if the key fob was washed or submerged?

Treat it as urgent. Water can cause corrosion that gets worse over days. Stop using it, dry it thoroughly, and consider professional replacement or repair—especially if you notice intermittent operation.

⏱️ Urgency Note: If the fob was exposed to water, shows intermittent function, or the battery area is corroded, act quickly—failure can become sudden and leave you unable to unlock or start the vehicle when you need it.
