If your Great Wall Motors key fob has weak range, needs multiple button presses, or shows a low-key warning, the fix is often as simple as replacing the small coin battery inside the remote. Most Great Wall Motors and GWM-family key fobs, including many newer Haval-related smart keys, commonly use a CR2032, while some older or slimmer remote designs may use a CR2025. The safest way to get the right battery is to open the fob and match the number printed on the old cell before buying a replacement. If you also drive a GWM vehicle and are comparing starting batteries for the vehicle itself, you can check Great Wall Motors for model-specific car battery options.

Buy Key Fob Battery Replacement for Great Wall Motors
Buying the right Great Wall Motors key fob battery starts with the battery code already inside your remote. For many modern Great Wall Motors smart keys, the battery is often a CR2032 3V lithium coin cell, while some slimmer or older GWM key fobs may use a CR2025. Because Great Wall Motors has used different key shell shapes and smart key designs across markets and model years, it is always better to match the printed battery number from your original cell instead of guessing by vehicle name alone. You can compare Great Wall Motors key fob battery replacements, browse CR2032 options for Great Wall Motors key fobs, or check CR2025 replacements for Great Wall Motors key fobs if you already know which one you need.
- CR2032 replacement battery: This is one of the most common sizes for newer Great Wall Motors smart keys and many GWM/Haval-style remotes. It offers a little more capacity than CR2025, but only buy it if the old battery inside your fob is marked CR2032. See CR2032 replacements for Great Wall Motors key fobs. Typical price: about $5 to $14 for a multi-pack.
- CR2025 replacement battery: Some Great Wall Motors remotes use this slightly thinner 3V coin battery. It should not be swapped with CR2032 unless your fob closes properly and the original battery code matches. Compare CR2025 replacement batteries that fit select Great Wall Motors key fobs. Typical price: about $5 to $12 for a multi-pack.
- Name-brand battery packs: If your Great Wall Motors key is used every day, a quality battery can help with more consistent range and better shelf life. Good options include Panasonic CR2032 batteries or Energizer CR2025 batteries depending on the battery size your remote uses. Typical price: about $6 to $15 depending on brand and pack size.
- Battery and shell kits: If the Great Wall Motors key fob still works but the shell is cracked, loose, or worn around the buttons, it can make sense to replace both the battery and the case at the same time. Browse Great Wall Motors key shell and battery kits. Typical price: about $10 to $25.

How to Replace a Great Wall Motors Key Fob Battery
- Gather the tools and replacement battery first. You will usually need the Great Wall Motors key fob, the correct CR2032 or CR2025 battery, and a small pry tool. Many owners use a small flathead screwdriver, a precision screwdriver set, or plastic pry tools to avoid marking the case.
- Remove the emergency key. Press the release button on the back or side of the Great Wall Motors fob and slide out the metal emergency key. This usually reveals the seam or slot used to separate the housing.
- Open the fob carefully. Insert the pry tool or flathead screwdriver into the seam near the emergency key slot and twist gently. Work around the housing slowly instead of forcing one spot. Many Great Wall Motors smart keys use tight plastic clips that can snap if pried too aggressively.
- Separate the two case halves. Once the housing starts to open, keep the internal rubber buttons and circuit board aligned. Do not shake the fob or turn it upside down abruptly.
- Check the old battery code before removal. Look directly at the battery and confirm whether it says CR2032 or CR2025. This is the most important step because Great Wall Motors key fob battery size can vary by remote style.
- Remove the old battery gently. Use a fingernail, plastic tool, or screwdriver tip to lift the battery out carefully. Avoid bending the metal retaining clip or scraping the contact points.
- Install the new battery in the same orientation. Make sure the positive side is facing the same way as the original battery. If the polarity is reversed, the Great Wall Motors fob may not respond at all even though the battery is new.
- Inspect the contacts and button pad. Before closing the fob, check that the battery is seated flat, the contact points are clean, and the rubber button pad is still aligned correctly.
- Snap the case back together. Press both halves together evenly until the clips lock back into place. Reinsert the emergency key fully.
- Test all functions near the vehicle. Check lock, unlock, panic, tailgate or trunk release if equipped, and passive start recognition on push-button-start Great Wall Motors models. If it still does not work, reopen the fob and verify battery size, orientation, and seating.
Common Great Wall Motors Key Fob Problems
- Key fob still does not work after battery replacement: The most common causes are the wrong battery size, reversed polarity, poor contact with the battery clip, or the battery not being fully seated.
- Weak lock and unlock range: If you have to stand close to the vehicle before the remote responds, the battery may be low quality, old from storage, or nearly depleted even though it is technically new. A fresh replacement battery from a trusted brand can help.
- Case will not close after installing the new battery: This usually means a CR2032 was installed where a CR2025 belongs, or the battery is not sitting flat in the tray. Never force the shell closed.
- Buttons feel sticky or worn: This is often a shell problem rather than a battery problem. If the circuit board still works, a replacement shell may solve the issue without needing a full new fob.
- Passive start or proximity unlock works inconsistently: On newer Great Wall Motors vehicles, a weak key battery can cause the vehicle to detect the key only when it is very close to the cabin or the start button.
- Warning message returns quickly: If the low-key warning comes back soon after replacement, the battery may be poor quality or the key fob may have an internal drain problem.
- Emergency key works but remote does not: That usually points to a battery, contact, or electronics issue inside the remote rather than a problem with the door lock itself.

Battery Replacement vs New Key Fob for Great Wall Motors
For most Great Wall Motors owners, replacing the key fob battery is the correct first step because it is quick, inexpensive, and often fixes the most common symptoms right away. If the remote still has occasional response, shows reduced operating range, or triggers a low battery warning, a fresh key fob battery replacement is usually the best place to start. In many cases, that is all the remote needs to return to normal operation.
A new key fob becomes the better option when the Great Wall Motors remote has broken buttons, a cracked board, water damage, or no response even after installing the correct fresh battery. If the electronics still work but the case is worn, a replacement shell may be enough. But if the remote itself has failed, a full replacement key fob may be needed, and depending on the model, it may also require cutting the emergency key and programming the remote to the vehicle.
Great Wall Motors Key Fob FAQ
What battery does a Great Wall Motors key fob use?
Most Great Wall Motors key fobs commonly use either a CR2032 or CR2025 3V lithium coin battery, depending on the key style and model year. The easiest way to confirm the correct battery is to open the fob and read the code printed on the old battery.
How do I know if my Great Wall Motors key fob battery is dying?
Typical signs include shorter operating range, needing to press the buttons multiple times, inconsistent passive entry, or a low key battery warning on the dashboard if your vehicle supports it.
Can I replace a Great Wall Motors key fob battery myself?
Yes. In most cases, replacing the battery is a simple DIY job that only takes a few minutes if you have the correct battery size and a small pry tool or screwdriver.
Will changing the battery erase my Great Wall Motors key fob programming?
No, a normal battery swap does not usually erase key programming. If the fob does not work afterward, the issue is more likely to be incorrect battery size, polarity, poor battery contact, or another problem with the remote.
Can I use a CR2032 instead of a CR2025 in my Great Wall Motors key fob?
Only if your original key fob was designed for a CR2032. A CR2032 is thicker than a CR2025, so using the wrong one can prevent the remote from closing properly or cause poor battery contact.
How long does a Great Wall Motors key fob battery last?
Battery life varies with use, climate, and battery quality, but many Great Wall Motors key fob batteries last roughly two to four years before performance starts to drop.
What should I do if the key fob still does not work after changing the battery?
Reopen the remote and verify the battery number, polarity, and seating. Also inspect the battery contacts and shell clips. If the fob still does not respond, the remote may need shell repair, electronic repair, or full replacement.
Do I need a new key fob or just a new battery for Great Wall Motors?
If the symptoms are weak range, delayed response, or a battery warning, start with a new battery. If the remote has physical damage, water damage, or no response at all with a fresh correct battery, then a shell replacement or full new key fob may be the better fix.
