2024 Ram 1500 Key Fob Guide (US): Types, Costs, Batteries & Programming

The 2024 Ram 1500 in the US market typically uses a proximity “smart key” fob for push-button start and keyless entry, with features varying by trim and option package. Many trucks also include remote start, and some support hands-free functions depending on equipment. Replacing or adding a fob generally requires pairing it to the truck’s immobilizer/security system, which consumers generally find is the main cost driver. Because part numbers, frequencies, and FCC IDs can vary within the same model year, confirming compatibility using the original fob and VIN is usually the safest approach.

Compatible Key Fob Types

The following key types are typically compatible with the 2024 RAM 1500. Compatibility varies by trim and options.

Proximity Smart Key Fob (Push-to-Start)

A proximity (PEPS) smart key fob that allows passive entry (unlock when near the truck) and push-button start. It contains a transponder/immobilizer chip and a remote transmitter; it must be programmed to the vehicle to start it.

Features

  • Passive keyless entry (proximity unlock/lock)
  • Push-button start authorization (immobilizer transponder)
  • Panic alarm (audible/visual)

Programming

🏢 Dealer Required

Programming typically requires secure immobilizer access and a scan tool with security authorization. Consumers generally find that adding keys often requires all existing keys to be present, and proof of ownership is commonly required. Some independent automotive locksmiths may be able to program depending on equipment and security access in your area.

⚠️ Common Issues

  • Fob works for lock/unlock but will not start the truck (not programmed to immobilizer or wrong chip)
  • Intermittent detection/no-start messages due to weak CR2032 battery or RF interference
  • Aftermarket shell swaps causing poor button contact or reduced range

Proximity Smart Key Fob with Remote Start

A proximity smart key fob that includes remote start in addition to passive entry and push-button start. Availability depends on trim and whether remote start is equipped from the factory or enabled by package.

Features

  • Remote start (when equipped and supported)
  • Passive keyless entry (proximity)
  • Push-button start authorization (immobilizer transponder)

🏢 Dealer Required

Remote start functionality typically requires the correct fob model plus vehicle support. Even if a fob has a remote-start button, it may not work unless the truck is equipped and the fob is the correct part/FCC ID. Programming generally requires secure immobilizer pairing; feature enablement (if needed) is separate from key programming.

⚠️ Common Issues

  • Remote start button present but remote start does not function (vehicle not equipped or wrong fob variant)
  • Reduced range after battery replacement due to incorrect battery orientation or weak cell
  • Used fobs that cannot be re-paired if previously locked to another vehicle

Total cost typically depends on whether you need a new OEM fob, programming labor, and whether all keys are lost. Dealers commonly charge more but are often the most straightforward for secure immobilizer programming. Many consumers find locksmith pricing varies widely by region and tool access. Aftermarket fobs can reduce parts cost, but compatibility and return policies are especially important.

🛒 Buyer's Checklist

Before purchasing a replacement key fob for your 2024 RAM 1500, verify these points:

1 Match the replacement to your original fob’s FCC ID and button layout (don’t rely on “fits Ram 1500” listings alone).
2 Confirm your truck has push-button start (proximity) and whether remote start is equipped before buying a remote-start fob.
3 Use your VIN to verify the correct OEM part number with a trusted source; mid-year changes can occur.
4 Avoid “universal” or unbranded fobs unless the seller clearly states immobilizer compatibility and return terms.
5 Plan for programming: budget for dealer or qualified locksmith programming and bring proof of ownership/ID as typically required.

⚠️ Common Mistakes to Avoid

✗

Buying a fob with the right look but the wrong FCC ID/frequency, leading to failed programming or short range.

✗

Assuming a used/secondhand fob will always program—some units may be locked, incompatible, or previously registered.

✗

Replacing the battery and assuming that fixes a no-start, when immobilizer pairing or a damaged fob is the real issue.

Frequently Asked Questions

Does the 2024 Ram 1500 key fob use a CR2032 battery?

Many 2024 Ram 1500 proximity fobs typically use a CR2032 coin-cell battery. Always confirm by opening the fob or checking the owner’s manual for your exact fob style, and replace with a quality brand cell to avoid early failure.

Can I program a 2024 Ram 1500 key fob myself?

For most US-market 2024 Ram 1500 proximity keys, consumers generally find programming is not a simple DIY process because immobilizer pairing usually requires secure scan-tool access. Options typically include dealer programming or a qualified automotive locksmith with the appropriate authorized equipment.

If my replacement fob has a remote start button, will remote start work?

Not necessarily. Remote start typically works only if the truck is equipped for it and the fob is the correct variant (often tied to specific part numbers/FCC IDs). A matching button layout alone does not guarantee feature support.
