It all started with the Dodge Ram, a single pickup developed by the Chrysler Corporation starting in 1980. That one model eventually grew into an entire line of Dodge trucks before breaking off into its own division. Today, Ram Trucks are some of the most powerful, reliable, and respected trucks on the market.

Ram Key Fobs — Everything You Need to Know

The Dodge Ram was first released under that name in 1981 and quickly cemented its place in U.S. automotive culture as one of the best pickups around. The Dodge Ram became simply the Ram in 2010 but is still under Stellantis’s ownership. Stellantis also owns Dodge and iconic brands like Jeep.

With the RAM 1500 TRX taking Motor Trend’s Truck of the Year for three consecutive years through to 2021, these vehicles are as popular today as ever. Dodge and RAM vehicles also boast some of the best keyless entry remotes around, with plenty of gadgets coming at a great price.

In our helpful guide, we’ll cover what types of keyless remotes service each RAM car or pickup and show you how to install a replacement battery without needing to call your dealer for support.

Types of Ram Keyless Entry Unit

The first three automotive remotes account for most RAM pickups, including these models:

  • 1500
  • 2500
  • 3500
  • 4500
  • 5500

The final parts we cover (the flip key fobs) are typically available for the RAM Promaster vehicles. For more information on which fob suits your car, contact your dealer.

Rectangular Key Fob

This popular remote will often come with your vehicle when you shop with a Dodge Ram dealer. It may come free with the vehicle or at an additional price, so check before you add it to your cart.

It has three buttons: two control the lock/unlock functions, while the third button adjusts the support provided by your air suspension. That’s right — your fob can help adjust the height of your vehicle. We find this to be a very cool addition, which makes this remote one of our favorite products. But it gets better with the next entry.

Rectangular Key Fob (Remote Start, Power Tailgate)

These items are identical in design to the three-button fob but come with two additional functions:

  • Remote Start: We know it’s just as easy to insert a key as it is to select a button to press. Still, start up a RAM 1500 car remotely when someone’s standing in front of it and see how they jump. Guaranteed hilarious results every time.
  • Power Tailgate: Designed for easy access when you want to open the tailgate, we view this as a great utility button.

While these items are available for many models, check that the make of the vehicle matches the remote when you go shopping. They may look identical, but a RAM 1500 remote won’t work for a 2500 model any more than a Jeep remote will work for a Dodge.

These models typically use a lithium coin battery, which is easy to search for and comes at a low price.

Teardrop Key Fob

Teardrop remotes are easy to search for and often come at a low price, so they’re a good choice if you want to save some cash. You’ll find that the functions of these remotes are similar to the rectangular models, with the basic functions typically allow you to unlock and enter the vehicle and lock it up. Some may help adjust air suspension or offer the power tailgate function.

These fobs use a CR2032 battery. Add a few to your cart — they’ll be handy long after today, and the price is almost nothing.

Flip Key Fob

The flip key models are typically aftermarket remotes and are associated with Promaster vehicles. If you’re a customer who is keen to have a brand-name item, your dealer will generally say, “call us for options,” which you can discuss further if you need to.

It’s understandable: whether it’s the beefy Jeep or RAM, Inc. logo you miss or just the risk of a problem with off-brand parts, it’s nice to have the best for your car.

These fobs also use a CR2032 battery.

  • DESIGNED TO LAST: 8-year leak-free shelf life

Ram Key Fob Battery Replacement

There comes a time when you need to address a dead battery and learn how to replace the battery in your Dodge Ram key fob. This isn’t a service you need to search out a locksmith or dealer for, though. You can save yourself the trouble of a phone call or email when you perform the service yourself. It’s just like changing the fob on Dodge or Jeep models.

Select the appropriate battery, unhinge the fob’s compartment, and set the new battery in place. Feel free to refer to any page in your car’s manual or back to our site page for assistance.

RAM Key Fob Programming

Dodge Ram key fob programming is best done by your local Dodge Ram dealer. If you’re a customer, they’ll be happy to hear from you if you contact them. Note that most dealers prefer to work with brand-name parts and ideally for vehicles that they’ve sold.

You can also search for a locksmith to program your fob. Ensure that the locksmith provides service for Dodge and RAM keys before you book an appointment.

FAQ

How much is a new Ram key fob?

You can get a fob for a very low price or pay more for a brand-name one. Follow the rule that higher price tends to equal better quality, but you can often find identical components in different stores for a very better price. Shopping around before you select a fob is your best bet.

How do I program my Dodge Ram key fob?

Phone or email your dealership or contact a reputable locksmith experienced with Dodge parts and offers a good price. If you have purchased an aftermarket product, you should call a locksmith, as most dealerships won’t work with these items.

How much does it cost to replace a Dodge key fob?

Most of the time, you can find a new Dodge key fob for well below $100. It depends on which model you want — some models with more functions or a brand design can come at a higher price.

How do I start my RAM without a key fob?

It’s best practice to keep an emergency key around in case your fob runs out of battery. However, there are methods for starting the vehicle when the battery is dead — we recommend that you only try these methods if you feel confident in what you’re doing, though!
