Need a Spare Key for a 2023 Chevy Silverado? Your Best Options (US)

A spare key for your 2023 Chevrolet Silverado can prevent a tow, a lockout, and expensive last-minute replacement costs. Because many 2023 Silverado keys use a transponder and remote functions, the spare usually needs to be properly programmed to your truck.

Understanding Your Situation

You still have a working key/fob, but you want an additional spare for backup, another driver, or peace of mind before the original is lost or damaged.

🚀 Immediate Steps to Take

  1. Confirm what you have now: a remote keyless entry fob, a key blade (if equipped), or both—then note your trim and whether you have push-button start.
  2. Gather essentials before calling: VIN, proof of ownership/ID, and your current working key(s) (having at least one working key often reduces cost and time).
  3. Decide what you want duplicated: remote functions only, a full programmed key that will start the truck, and/or an emergency key blade.

Your Options

Chevrolet dealer OEM key + programming

Cost: $250-$600 Time: Same day / 1-3 days

The dealer supplies an OEM key/fob (and key blade if applicable) and programs it to your Silverado using GM service tools. They can also verify compatibility by VIN and update modules if required.

âś“ Pros:
  • Highest compatibility confidence (OEM parts matched by VIN)
  • Programming is performed with factory-level equipment and procedures
âś— Cons:
  • Typically the most expensive option
  • May require an appointment and ordering parts

Automotive locksmith (mobile) key/fob + programming

Cost: $180-$450 Time: Same day

A licensed automotive locksmith comes to you with compatible key/fob inventory and programming tools to add a spare to your truck’s immobilizer system. Many can also cut an emergency key blade on-site if your setup uses one.

âś“ Pros:
  • Usually faster and more convenient (mobile service)
  • Often less expensive than the dealer
âś— Cons:
  • Capability varies—some locksmiths may not support every 2023 Silverado configuration
  • Aftermarket fobs can have shorter range or durability compared with OEM

Buy a fob online, then pay for programming locally

Cost: $120-$450 total Time: 1-7 days

You purchase a compatible fob (OEM or aftermarket) and then hire a dealer or locksmith to program it. If a physical key blade is required, you’ll also need it cut to match your truck.

âś“ Pros:
  • Potential savings if you source a genuine OEM fob at a good price
  • More control over which part you buy (OEM vs aftermarket)
âś— Cons:
  • Wrong part numbers are common; returns can be a hassle
  • Some dealers/locksmiths won’t program customer-supplied or used fobs

Add an emergency key blade only (if your configuration supports it)

Cost: $20-$80 Time: Same day

If your Silverado setup uses an emergency/backup mechanical key blade, you can have a duplicate cut for door access. Note: this typically will not start the vehicle unless paired with a programmed transponder system (where applicable).

âś“ Pros:
  • Inexpensive backup for lockout situations
  • Quick to get cut at a locksmith or some hardware/key shops (when compatible)
âś— Cons:
  • May not start the truck—often only helps with physical entry
  • Not all shops can cut or source the correct high-security key blank

⚠️ What to Avoid

✕ Buying a used or “refurbished” fob without confirming it can be re-learned to your vehicle—many are locked to the original vehicle and won’t program.

✕ Waiting until you’re down to zero working keys—spares are usually cheaper and simpler to add when you still have a working key.

âś• Using unverified sellers or ultra-cheap fobs that may have poor range, short battery life, or inconsistent programming compatibility.

⚠️ Common Mistakes to Avoid

  • Waiting until emergency
  • Not testing spare immediately
  • Buying incompatible aftermarket
  • Overpaying at dealership

Frequently Asked Questions

Can I program a spare key/fob for a 2023 Silverado myself?

Sometimes remote functions can be paired, but most 2023 Silverado “start the vehicle” keys require immobilizer programming with professional tools. The exact process depends on your trim, start system, and key type, so confirm with a dealer or qualified automotive locksmith.

Do I need to bring the truck in to get a spare made?

A dealer typically requires the vehicle present for programming. Many automotive locksmiths are mobile and can program a spare on-site, as long as they support your specific 2023 Silverado configuration and you can provide proof of ownership.

Will an aftermarket fob work the same as OEM?

Sometimes, but quality varies. Aftermarket fobs may have reduced range, different button feel, or shorter lifespan. OEM usually offers the best fit and consistency, especially for newer vehicles.

What information will I need to get a spare key made?

Expect to provide your VIN, government-issued ID, and proof of ownership/registration. Having your current working key/fob available can also speed up the process and may reduce cost.

⏱️ Urgency Note: If you’re down to one working key, prioritize getting a spare soon. Losing the last key can increase cost significantly and may require towing or additional security/immobilizer procedures.
