If your 2019 Jeep Cherokee key fob is not working, needs a battery replacement, or you simply want to access the emergency key, you need to open the fob. Many drivers feel nervous about opening a key fob, but with the right approach, it’s quick and safe. This guide explains how to open your 2019 Jeep Cherokee key fob, step-by-step, with practical tips and clear warnings.
Why Open Your Jeep Cherokee Key Fob?
There are three main reasons you may need to open your key fob:
- Battery replacement – Key fobs use coin batteries that last 1-2 years. A weak battery may cause your Jeep not to unlock or start.
- Emergency key access – If your fob is dead, you can use the hidden physical key to unlock your Jeep manually.
- Cleaning or repairs – Dust or moisture can cause buttons to stick or stop working.
Opening your fob is simple, but it requires careful handling. The 2019 Jeep Cherokee fob is designed to be opened by owners, not just professionals.
What You Need Before You Start
To open your fob safely, gather the following:
- Small flathead screwdriver
- New CR2032 coin battery (for battery replacement)
- Clean cloth (optional for cleaning)
- Patience and gentle hands
Never use excessive force. The fob has plastic clips that can break if you pry too hard.
Step-by-step Guide: Opening The 2019 Jeep Cherokee Key Fob
Follow these steps to open your key fob without damage:
1. Locate The Seam
Hold the fob so you see the seam running around its edge. This is where the two halves meet.
2. Remove The Emergency Key
Slide the small latch or press the button on the fob to release the physical key. Pull it out and set it aside.
3. Insert The Screwdriver
Place the flathead screwdriver into the seam (usually near the key slot or battery symbol). Gently twist or wiggle the tool to separate the halves.
*Tip:* If the seam is tight, try moving the tool along the edge until you find a spot that gives way.
4. Open The Fob
The fob will split into two parts. Inside, you will see the battery compartment and the circuit board.
5. Replace The Battery Or Access Emergency Key
If changing the battery, remove the old CR2032 and insert the new one. Make sure the positive side faces up.
6. Reassemble
Align the two halves and press them together until you hear a click. Insert the emergency key back into its slot.

Common Mistakes When Opening A Key Fob
Many owners make errors that can lead to expensive repairs. Watch out for these:
- Using too much force – This can break clips or crack the shell.

- Touching the circuit board – Oils or dirt from your fingers can cause malfunctions.

Comparison Table: Jeep Cherokee Key Fob Vs. Other Brands
Understanding how your Jeep fob compares to others can help you avoid mistakes:

Extra Tips For Safe Key Fob Opening
- Use a plastic tool if you worry about scratches.
- Place the fob on a soft surface to prevent damage.
- If you see corrosion or moisture inside, clean gently with a dry cloth.
- If your fob still does not work after battery replacement, check if the circuit board is loose.
A non-obvious insight: Many fobs start working again after simply opening and closing them, because dust or moisture gets released. Another tip: Always buy a high-quality battery. Cheap batteries can leak or fail faster.
When To Call A Professional
If your key fob does not open easily, or if you see damage inside, consider visiting a dealership or locksmith. Some repairs require special tools or expertise.
