Learning how to open Chrysler key fob is a straightforward task that doesn’t require special tools or technical expertise. This guide will walk you through the entire process, from releasing the valet key to prying the case open and replacing the battery. With these clear instructions, you can confidently perform this key fob maintenance at home in just a few minutes, restoring the full functionality of your keyless entry system and getting back on the road without any hassle.
Why Knowing How to Open Your Key Fob Is Important
Knowing how to open your Chrysler remote is a valuable skill that saves you from the inconvenience and expense of a dealership visit for a simple battery replacement. A malfunctioning key fob can leave you stranded or unable to access your car’s features. By understanding the fob disassembly process, you empower yourself to handle this common maintenance task quickly and efficiently. This knowledge not only saves money but also gives you the confidence to manage other small car maintenance jobs, making you a more self-reliant vehicle owner.
9 Step-by-Step Guide: How to Open Chrysler Key Fob
Step 1: Locate and Release the Valet Key
The first step in opening your Chrysler key fob is to release the hidden mechanical key, often called the valet key. Look for a small release latch or button on the side or back of the key fob. On most modern Chrysler remotes, this is a small sliding switch. Press or slide this latch, and the metal key will pop out or become loose enough to pull free from the fob’s body. This key not only serves as a backup for your door but also acts as a tool in the fob disassembly process, making it an essential first step.
Step 2: Identify the Seam for Fob Disassembly
With the valet key removed, carefully inspect the key fob casing to locate the seam where the two halves of the plastic shell connect. This seam runs along the perimeter of the fob. In the slot where the valet key was housed, you will often find a small indentation or pry point specifically designed to help you separate the casing. This is the spot where you will insert a tool to begin prying the two halves apart. Understanding the location of this seam is fundamental to the entire process of opening your Chrysler remote without causing damage.
Step 3: Use a Tool to Gently Pry the Casing Apart
Insert the tip of a small flathead screwdriver or the end of the valet key itself into the pry point or seam you identified in the previous step. Gently twist the tool to create a small gap between the two halves of the key fob. Be careful not to apply too much force, as this can crack the plastic casing. Work your way slowly around the seam, twisting gently every half-inch or so. You will hear small popping sounds as the internal clips disengage. This careful prying is the core technique for how to open your Chrysler key fob.
Step 4: Separate the Two Halves of the Key Fob
Once you have worked your way around the entire seam and all the clips have been disengaged, the two halves of the key fob should separate easily. Do not force them apart if you feel resistance; instead, go back and check for any clips that may still be connected. Carefully lift one half of the casing away from the other. Inside, you will see the internal components, including the green circuit board and the round, coin-style battery. Set one half of the casing aside, being mindful not to disturb the sensitive electronics.
Step 5: Remove the Old Battery
The battery is typically a flat, silver, coin-shaped cell held in place by a small clip or cradle. Note the orientation of the battery before you remove it; usually, the side with the lettering and the “+” symbol faces up. Use a small, non-metallic tool, like a plastic pry tool or even your fingernail, to gently pop the old battery out of its holder. Avoid using metal tools like a screwdriver to pry out the battery, as you could accidentally short the circuit board or scratch the contacts, leading to further issues with your keyless entry system.
Step 6: Identify and Purchase the Correct Replacement Battery
With the old battery removed, examine it to identify the battery type, which is printed on the surface. Most Chrysler key fobs use a CR2032 battery, which is a common and inexpensive coin cell battery available at most grocery stores, electronics stores, and pharmacies. It is crucial to use the exact same type of battery for the replacement to ensure proper functionality and prevent damage to your Chrysler remote. Taking a photo of the old battery before you dispose of it is a great way to ensure you purchase the correct one.
Step 7: Install the New Battery
Once you have the correct replacement battery, you are ready to install it. Ensure the battery’s positive (+) side is facing up, matching the orientation of the old battery you removed. Gently slide the new battery into the holder until it clicks securely into place. Make sure it is seated firmly and makes good contact with the metal terminals. A loose battery can cause intermittent connection issues, which might make you think the fob is still broken. This is a critical point in how to open Chrysler key fob and successfully complete the battery replacement.
Step 8: Reassemble the Key Fob Casing
With the new battery installed, it’s time to reassemble the fob. Align the two halves of the plastic casing, ensuring the internal components are properly seated. Gently press the two halves together, starting at one end and working your way around the perimeter. You should hear a series of clicks as the internal clips re-engage. Apply firm, even pressure until the seam is completely closed and there are no gaps. The fob should feel solid and secure once it is properly snapped back together.
Step 9: Test the Functionality of Your Key Fob
After reassembling the fob, the final step is to test it. Stand near your vehicle and press the lock, unlock, and any other buttons to ensure they are all working correctly. If the fob does not work, the most common issues are an incorrectly installed battery (upside down), a poor connection, or a dead new battery. Re-open the fob and double-check your work. Once you confirm that the keyless entry system is responding correctly, re-insert the metal valet key into its slot. Your key fob maintenance is now complete.
Key Fob Maintenance Benefits
Regular key fob maintenance offers several benefits that can save you time and money while ensuring the reliability of your vehicle’s keyless entry system. By routinely inspecting and replacing the battery when necessary, you can avoid unexpected failures that may leave you locked out of your vehicle. Proper maintenance also helps preserve the internal components of the fob, preventing wear and damage that could lead to costly repairs or replacements. Additionally, keeping your key fob clean and functional enhances convenience, allowing uninterrupted access to your car’s security features and other functionalities, such as remote start or trunk release.
Frequently Asked Questions
What Kind of Battery Does My Chrysler Key Fob Use?
Most modern Chrysler key fobs use a CR2032 3-volt coin cell battery. This is a very common type of battery that can be found at most drugstores, grocery stores, and electronics retailers. However, it is always best to open your key fob and check the specific number printed on the old battery before purchasing a replacement to ensure you get the correct one for your model.
Will I Need to Reprogram My Key Fob After Changing the Battery?
No, in most cases, you will not need to reprogram your Chrysler key fob after a battery replacement. The fob’s internal memory stores the programming, and it is not lost when the battery is removed. As long as you replace the battery within a reasonable amount of time, the fob should work immediately once the new battery is installed.
How Do I Know If My Key Fob Battery Is Dying?
The most common sign of a dying key fob battery is a reduced signal range. You may find that you have to be much closer to your vehicle for the buttons to work. Other signs include needing to press a button multiple times for it to register, or the keyless entry system working intermittently. Your vehicle’s dashboard may also display a “low key fob battery” warning message.
What Tools Do I Need to Open My Chrysler Key Fob?
You need very few tools for this job. In many cases, the only tool you need is a small flathead screwdriver to gently pry the case open. For some models, the valet key itself can be used as a pry tool. It is also helpful to have a non-metallic pry tool (like a plastic one) to remove the battery without risking damage to the circuit board.
What Should I Do If My Key Fob Still Doesn’t Work After Replacing the Battery?
If the fob still isn’t working, first re-open it to ensure the battery is installed correctly with the positive side facing up and making a firm connection. Check that the battery contacts are clean and not bent. If it still fails, it’s possible the new battery is faulty. If all else fails, the issue may be with the fob’s internal electronics, at which point you may need to visit a dealership or an automotive locksmith.
