Key Fob Stolen: What to Do for a 2023 Chevy Silverado (US)

If your 2023 Chevrolet Silverado key fob was stolen, treat it as an urgent security issue—especially if the thief may know where the truck is parked. The goal is to prevent unauthorized entry/start, document the theft, and get new keys programmed while removing the stolen fob from the truck’s memory.

Understanding Your Situation

A stolen key fob can allow someone to unlock and potentially start your Silverado (depending on proximity and security conditions). Even if the truck isn’t taken immediately, the stolen fob remains a valid credential until it’s erased/disabled and replaced with newly programmed keys.

🚀 Immediate Steps to Take

  1. Secure the vehicle now: move it to a safe location (garage if possible), lock it, and remove valuables. If you have a second key, keep it with you—not in the vehicle.
  2. Report and document: file a police report and note the fob type (remote keyless entry / push-button start) and any identifying info. Contact your insurer if comprehensive coverage applies.
  3. Arrange key security service ASAP: contact a Chevrolet dealer or a qualified automotive locksmith to erase the stolen fob from the vehicle and program replacement fobs; ask about immobilizer/keyless system reprogramming for a 2023 Silverado.

Your Options

Chevrolet dealer: erase stolen fob + program new OEM fobs

Cost: $250-$700+ Time: Same day to 1-3 days

The dealer verifies ownership, connects factory diagnostic equipment, removes the stolen fob from the vehicle’s authorized list, and programs new OEM key fobs (and any remaining fobs) to the truck. They can also check for related security updates and confirm all lost keys are no longer recognized.

âś“ Pros:
  • Factory-level programming and compatibility for a 2023 model
  • Ensures the stolen fob is removed from the vehicle’s memory
âś— Cons:
  • May require towing if you have no working key or if all keys are lost
  • Often higher cost and appointment delays compared with a locksmith

Mobile automotive locksmith: on-site replacement + key/fob deletion

Cost: $200-$600 Time: Same day

A qualified locksmith comes to the vehicle, verifies ownership, and uses professional programming tools to add new fobs and (when supported) remove the stolen fob from memory. This is typically faster if the truck is stranded or you can’t get to a dealer easily.

âś“ Pros:
  • Convenient on-site service (no dealer visit required)
  • Often faster scheduling and potentially lower cost
âś— Cons:
  • Capability varies by locksmith/tooling for late-model GM vehicles
  • Aftermarket fobs may have reduced range/features vs OEM (depending on part used)

Insurance claim (comprehensive) + security reset/rekey as needed

Cost: $0-$500+ (deductible-dependent) Time: 1-7 days

If your policy covers stolen keys or theft-related expenses, insurance may reimburse part of the cost for replacement fobs, programming, and in some cases towing. You’ll still need a dealer/locksmith to erase the stolen fob and program new ones.

âś“ Pros:
  • May significantly reduce out-of-pocket cost
  • Creates a documented record tied to the theft report
âś— Cons:
  • Deductible may exceed the repair cost
  • Claims process can add time and paperwork

⚠️ What to Avoid

✕ Don’t assume the truck is safe just because it’s locked—if the stolen fob remains authorized, it can still work until removed from the vehicle’s system.

✕ Don’t buy the cheapest unverified fob online and expect it to program—wrong frequency/part number or poor-quality units can waste time and money.

✕ Don’t leave the spare key in or near the vehicle (center console, glovebox, or inside a nearby bag). Keep all remaining keys secured and separate.

⚠️ Common Mistakes to Avoid

  • Not deactivating stolen key
  • Delaying reprogramming
  • Not filing police report
  • Ignoring security risk

Frequently Asked Questions

Can someone start my 2023 Silverado if they stole my key fob?

Potentially, yes. A stolen, still-authorized fob can unlock the truck and may allow starting depending on proximity and the vehicle’s security system. The safest approach is to have the stolen fob erased from the vehicle and new fobs programmed as soon as possible.

Do I need to replace locks if my key fob was stolen?

Often, the priority is electronic security: deleting the stolen fob and programming new ones. Physical lock replacement is usually only considered if a physical key blade was stolen and you’re concerned about mechanical entry. A dealer or locksmith can advise based on your Silverado’s key type and risk factors.

Will erasing the stolen fob stop it from working?

Yes—once the vehicle’s system removes that fob from its authorized list, it should no longer unlock or start the truck. Make sure the service provider confirms how many keys/fobs are currently learned and that all missing ones were removed.

What if I don’t have a spare key?

You’ll likely need a dealer or well-equipped automotive locksmith to generate/program a new key/fob. In some cases the truck may need to be towed to the dealer, so ask about mobile options and what proof of ownership is required.

⏱️ Urgency Note: High urgency: if the stolen fob could be linked to your truck’s location (stolen from your home, gym, or workplace), move the vehicle and arrange fob deletion/reprogramming immediately to reduce theft risk.
