Remember the days of sticking a Jeep car key in, turning the ignition, and getting on the road? Times have changed with the rising popularity of Jeep key fobs, which are also called Jeep keyless entry remotes.

As a Jeep owner, you’ll want to stay in the know when it comes to Jeep keyless entry remotes. Below, you can discover everything you need to know about owning, troubleshooting, and replacing a Jeep keyless entry remote.

What Jeeps Have Key Fobs?

The following types of Jeeps are vehicles that have key remotes:

  • Wrangler
  • Renegade
  • Patriot
  • Liberty
  • Grand Cherokee
  • Cherokee
  • Gladiator
  • Compass
  • Commander

How Do Jeep Keyless Entry Products Work?

This innovative Jeep car key features a chip that communicates with the transponder located inside a vehicle. Vehicle owners can enter and drive their vehicles just by holding these little accessories. It’s the connection to the car’s transponder that makes this convenience possible.

Keep in mind that you will have to push a button on your car’s door handle (while holding the Keep keyless entry remote) to get inside. When you’re ready to drive away, you’ll push another button located near the gear shift and press down on the brake simultaneously. The best part about a Jeep keyless entry remote? You don’t have to fumble for a traditional car key amid a million other items in the depths of your purse.

Do I Need to Replace My Jeep Key Fob?

You shouldn’t be so quick to start shopping for a replacement Jeep key fob. There’s a chance that your current fob just needs a new battery.

Replacing the battery of your car key can seem like rocket science if you’ve never done it before. Luckily, the process isn’t that hard — you can discover how to do it below:

How to Replace Your Jeep Car Key’s Battery

The best starting point we can offer is to turn to page 1 of your car’s user manual and go from there. This method will give you the most accurate steps to follow for your specific vehicle. Or, you can email your dealer for help.

But, the battery replacement process is the same for most Jeep key fobs. You’ll have to open the fob’s casing using a small flat head screwdriver. You can also use a knife to open remotes, but always exercise caution to avoid getting hurt.

Most batteries (like CR2025 and CR2032 3-Volt) for car remotes cost under $5. If you don’t feel comfortable replacing the battery yourself, you can contact your dealer and see if they will do it for an affordable price.

What Is the Price of a Jeep Fob?

If you purchase a brand-new vehicle, your dealer will likely supply you with at least two free OEM remotes. This way, you’ll have at least a couple of OEM (original equipment manufacturer) remotes to operate your car. You can store one of these free OEM remotes in your purse and the other on your key rack at home.

However, you might be wondering the price of a fob if you shop for one separately. After reading others’ experiences on Google, the results tell us that the price of a Jeep key fob can cost as much as $250 or more.

But, not every vehicle owner will find these high prices for an OEM key fob. The price you pay will depend on your car’s model and how high-end it is. For example, a brand-new 2021 Grand Cherokee L’s fob will be much more expensive than a 2016 Compass’s.

How Much Does It Cost to Replace a Jeep Key Fob?

Most Jeep, Inc. vehicle owners won’t have to pay full price as they shop for a new OEM (original equipment manufacturer) key fob, especially if they have a newer vehicle. A customer should always check their coverage materials to see if any page details their entitlement to a free or reduced-price OEM fob replacement:

  • Your car insurance policy/account
  • The warranty on your car (and your extended warranty coverage)
  • Your automotive club membership

Your automotive dealer might make you send in your old fob, or they may send you a new one with no questions asked. Your dealer will invite you to “email or call us” and discuss the replacement process and email message you if they have your desired remote in stock.

If a customer doesn’t qualify for a free or cheaper OEM fob replacement, they can expect to pay for the full price of a new one. As mentioned earlier, the price a customer has to pay will vary depending on their Jeep’s specific model.

How Do I Get a New Jeep Key Fob?

Maybe a battery replacement for your 2021 Jeep key fob didn’t work. Or, perhaps you know you left your only copy at the local pizza shop on your out-of-town vacation. If your fob is beyond repair or lost in oblivion, you’ll need to shop for a new one.

When shopping for a new Jeep key remote, you have several options. Buying it online from Amazon or another marketplace is a viable route to take. Shop the remotes for your specific model, search for the best price, and add the item to your online cart. Consider adding several items so that you have a replacement Jeep remote if you ever need it.

From here, you can hook up your preferred payment method (American Express, Visa, Mastercard, Paypal, etc.). Type in your contact details, click “place order” on the site, and have the seller ship the OEM (original equipment manufacturer) products to your home address. Shipping should only take a few days, and you can even pay for expedited shipping to receive your replacement Jeep remote quicker.

Once the accessories arrive, you’ll need to program them to your model. If you have an older vehicle, you might be able to complete the programming yourself. However, for a safe and secure customer experience, you’ll need to bring a newer Jeep to your dealer or visit a car service center or automotive locksmith that has the appropriate technology.

The Importance of Finding the Right Jeep Keyless Entry Remote

Getting a key fob online is easy, as you can use whatever payment method works for you (American Express, Visa, Mastercard Paypal, etc.) and pay for quick shipping to your house. Or, you can avoid messing with an online cart and try your luck at the dealer. But, they might make you pay a higher price for the service of having someone else program it.

Even if you have a remote or two at your disposal, it isn’t a bad idea to shop for a spare. A spare can save you in a pinch even if you think you’ll never need one.

As you’re shopping for a Jeep car remote (whether for a 2021 model or an older one), ensure you find the right remote and view your model’s specific programming guidelines.

If you have questions, your local vehicle dealer should encourage you to email them or click on the “call us” button on their official site.
