2023 Chevrolet Silverado Key Fob Guide (US): Types, Batteries, Costs & Programming

The 2023 Chevrolet Silverado (US market) commonly uses a GM proximity “smart key” system on many trims, while some configurations use a more basic remote keyless entry (RKE) setup. Exact key fob style and features vary by trim (WT, Custom, LT, RST, LTZ, High Country), cab/option packages, and whether the truck has push-button start. Most Silverado fobs use a coin-cell battery and require programming that consumers typically obtain through a dealer or an automotive locksmith with GM-capable tools. Because look-alike fobs are widely sold online, confirming FCC ID and part compatibility before purchase is a key consumer-protection step.

Compatible Key Fob Types

The following key types are typically compatible with the 2023 Chevrolet Silverado. Compatibility varies by trim and options.

Proximity Smart Key Fob (Push-Button Start)

A proximity (Passive Entry/Passive Start) smart key fob that allows the truck to unlock when you approach and start with a push-button when the fob is inside the vehicle. Many 2023 Silverado trims/packages use this style, often paired with remote start and a built-in emergency key blade.

Features

  • Passive entry (keyless unlock/lock when near the truck, if equipped)
  • Push-button start (if equipped)
  • Remote start (common on many trims; depends on equipment)

Programming

🏢 Dealer Required

Programming typically requires a GM-capable scan tool/security access. Many late-model GM vehicles require online authorization and/or an account-based security process, so consumers generally find DIY programming is not supported for adding a new proximity fob. If all keys are lost, additional steps (proof of ownership, immobilizer reset/learn procedure) are commonly required.

⚠️ Common Issues

  • Intermittent detection or 'No Remote Detected' messages (often weak battery or interference)
  • Remote start not working due to vehicle settings, hood switch, or low fob battery
  • Aftermarket fob not accepted because FCC ID/part number or frequency is incorrect

Remote Keyless Entry (RKE) Key Fob (Non-Proximity / Turn-Key Start on some configurations)

A traditional remote keyless entry fob used to lock/unlock and control functions like panic and (when equipped) remote start. This style is typically used on configurations without proximity/push-button start, and it may be paired with a separate physical key for ignition/door operation depending on the truck’s equipment.

Features

  • Remote lock/unlock
  • Panic alarm
  • Remote start on equipped vehicles

🏢 Dealer Required

Many replacements still require professional programming with GM-capable tools. Some vehicles allow limited onboard procedures for certain remotes, but consumers generally find late-model GM trucks often require scan-tool programming to add a new fob, especially when immobilizer/anti-theft integration is involved.

⚠️ Common Issues

  • Reduced range (battery aging or internal button wear)
  • Buttons stop responding after water exposure or drops
  • Wrong frequency/part number purchased online leading to non-functional remote

Emergency Key Blade / Mechanical Key Insert (for Smart Key Fobs)

A hidden mechanical key insert (often stored inside the proximity fob) used to unlock the driver door if the fob battery is dead or the remote functions fail. It does not provide remote functions by itself.

Features

  • Manual door unlock when the fob battery is dead
  • Backup access method
  • Can be duplicated/cut as a spare

A mechanical insert typically only needs to be cut to match the vehicle’s locks. If a separate transponder key is used on a specific configuration, that transponder (if present) would require programming; consumers should confirm their exact ignition/anti-theft setup before ordering cuts.

⚠️ Common Issues

  • Insert key not cut correctly or not fully seated in the fob
  • Door lock cylinder stiff from infrequent use
  • Confusion between the emergency blade and a programmed ignition key

Best for: DIY-capable owners, budget-conscious

Pricing typically depends on whether you need a new fob only, cutting of an emergency blade, and whether you have at least one working key. All-keys-lost situations are usually the most expensive due to added security/immobilizer procedures. Aftermarket fobs can reduce parts cost, but consumers generally find programming and compatibility risk are higher if identifiers don’t match exactly.

🛒 Buyer's Checklist

Before purchasing a replacement key fob for your 2023 Chevrolet Silverado, verify these points:

1 Match the replacement to your original by FCC ID, GM part number, and button layout (remote start/tailgate buttons vary).
2 Confirm whether your truck is proximity/push-button start or a non-proximity RKE setup before buying.
3 Buy from a seller with clear return terms and a stated compatibility guarantee for 2023 Silverado (US).
4 Avoid “universal” claims; consumers generally find GM fobs are model/trim/package specific and must match frequency and security type.
5 Plan for programming: call ahead to confirm the dealer/locksmith can add keys for a 2023 GM truck and ask for an all-keys-lost price if applicable.

⚠️ Common Mistakes to Avoid

✗

Ordering a look-alike fob that has a different FCC ID/part number or different feature set (e.g., tailgate/remote start), causing programming failure.

✗

Assuming DIY programming will work; many late-model GM fobs typically require professional programming with security access.

✗

Replacing the fob when the issue is actually a weak CR2032 battery, dirty contacts, or a damaged button pad.

Frequently Asked Questions

What battery does a 2023 Chevrolet Silverado key fob use?

Many 2023 Silverado key fobs use a CR2032 coin-cell battery. Confirm by checking the battery marking after opening the fob or by referencing the owner’s manual for your exact fob style.

Can I program a 2023 Silverado key fob myself?

Often, no. Consumers generally find 2023 GM truck fobs typically require dealer or automotive locksmith programming with GM-capable tools and security access, especially for proximity/push-button start systems.

How do I make sure an online key fob will work with my Silverado?

Match the FCC ID and GM part number from your original fob, confirm the same button layout and features (remote start/tailgate), and verify it’s intended for the US market. If the seller can’t provide exact identifiers or a return policy, it’s usually safer to choose a different source.
