Ram Key Fob Replacement: Cost, Options, and Programming

Ram trucks were sold as Dodge Ram until Ram became its own brand around the 2010 model year, and the keys still use the same Chrysler-family security system, known as Sentry Key or SKIM. That shared heritage means parts and tools are widely available, but it also means newer trucks have a security gateway that complicates DIY programming.

Below are Ram key types by era, battery sizes, replacement options, and what to expect from a dealer or locksmith. For a cross-brand overview, see how much a new key fob costs.

Ram Key Fob Replacement Cost at a Glance

All-keys-lost jobs and trucks that need a security gateway bypass usually land at the higher end.

Ram Key Types by Era

Older Dodge Ram trucks

Older pickups use a cut transponder key working with the Sentry Key Immobilizer Module plus a separate keyless entry remote. These are the cheapest to replace, and some years supported customer programming of an extra key when two working keys were available.

Remote head keys

Around the 2009-2012 generation, many Ram trucks used a key with the remote buttons molded into the head. The blade is cut and the chip and remote are programmed together.

Fobik keys

From about 2013 to 2018, many Ram 1500 and HD trucks used the Chrysler “Fobik,” a rectangular fob that plugs into the dash ignition with a small emergency blade inside. Trucks with Keyless Enter ‘n Go use a proximity version. The Ram 1500 Classic kept this style after the new generation launched.

Newer smart keys

The redesigned 2019+ Ram 1500 and newer HD trucks use an updated smart key with push-button start, often with remote start, tailgate, and air suspension buttons depending on trim.

Ram ProMaster

The ProMaster van is based on a Fiat design and uses a flip key rather than a Fobik, so parts and programming differ from Ram pickups.

Ram Key Fob Battery Sizes

Fobik keys commonly use a CR2032. Many 2019+ Ram 1500 smart keys use a larger CR2450, although some listings show a CR2032, so open your fob before buying. ProMaster flip keys and older separate remotes vary by year. Step-by-step help is in our Dodge and Ram key fob battery replacement guide, since Ram and Dodge share most fob designs. A cracked 2019 Ram 1500 case can often be fixed with a new shell instead of a new fob.

Ram Replacement Options Compared

Ram dealer

Pros: OEM fob matched by VIN, factory software, handles security gateway access and the newest trucks. Cons: Highest price; the truck must come in for programming. Who it suits: New trucks, warranty work, and difficult all-keys-lost cases.

Automotive locksmith

Pros: Often cheaper, mobile service at your jobsite or driveway, and broad Chrysler-family tool coverage. Cons: The locksmith needs the truck’s PIN (retrieved through their tool or an authorized channel) and, on newer trucks, gateway access. Who it suits: Most Ram owners.

Aftermarket fob online

Pros: Lower part price. Cons: Must match the FCC ID, part number, and button layout; you still pay for programming. Some aftermarket Fobiks are sold as reusable if the first programming attempt fails, but that is a seller claim. Read are aftermarket key fobs any good first, and use how to find the FCC ID to match parts.

Can a Used Ram Key Fob Be Reprogrammed?

Usually not as is. Chrysler-family fobs, including Ram Fobiks and smart keys, are generally locked to the first vehicle they are programmed to. Some locksmith tools can unlock or renew certain fobs so they can be programmed again, but it depends on the fob generation and the tool. A used fob may still be able to work the locks on another truck while being unable to start it. Before buying used, call your locksmith with the part number, and see reprogramming a used key fob.

How Ram Key Programming Works

Programming a Ram key means adding it to the Sentry Key system, and the method depends on the year:

• Older trucks: Some years allow customer programming of an extra key using two working keys and an ignition sequence. Check the owner’s manual for your year.
• Fobik and smart key trucks: A scan tool and the vehicle’s security PIN are normally required.
• Newer trucks with a security gateway: Many Chrysler-family vehicles from around 2018 on have a Secure Gateway Module. Aftermarket tools need an authorized login or a bypass cable to program keys.

Dealer vs Locksmith for Ram Trucks

For Fobik-era trucks, a locksmith is usually faster and cheaper, and mobile service matters when the truck is at a jobsite. For a 2019+ Ram 1500 with all keys lost, call ahead: some locksmiths handle these routinely, while others will send you to the dealer. Ram shares most of its key hardware with Dodge, so our Dodge key fob replacement guide is a useful companion.

How to Save on a Ram Key

• Replace the battery first, then try the emergency start method in your owner’s manual.
• If only the case is broken, swap the shell. See key fob shell replacement.
• Add a spare while you have a working key.
• Ask for an all-in quote including PIN retrieval and gateway access.

Ram Key Replacement Checklist

• Identify the key: transponder, remote head, Fobik, smart key, or ProMaster flip key.
• Note the FCC ID and part number.
• Count your working keys.
• Have the VIN, registration, and ID ready.
• Confirm the locksmith can handle the PIN and security gateway on your truck.
