Setup and Installation
This product is a key shell only. Installation involves transferring the internal electronics from your existing key fob into this new shell. No programming is required if you are transferring existing components.
Required Tools:
- Small flathead screwdriver or pry tool (for opening key fobs)
- Small Phillips head screwdriver (if your original key fob or new shell uses screws)
Installation Steps:
- Open Your Original Key Fob: Carefully use a small flathead screwdriver or pry tool to separate the two halves of your existing key fob. Locate and remove the internal circuit board, transponder chip, and battery. Note their orientation.
- Prepare the New Key Shell: If the new shell has a blank key blade, you will need to transfer your original cut key blade or have the new blade cut by a locksmith. If your original key blade is integrated, you may need to transfer the entire blade assembly.
- Insert Components: Carefully place your original circuit board, transponder chip, and battery into the corresponding slots within the new Acouto key shell. Ensure they are seated correctly and securely.
- Close the New Key Shell: Align the two halves of the new key shell and press them firmly together until they snap into place. If a small screw was provided, use it to secure the shell if there is a designated screw hole.
- Test Functionality: Test all buttons (lock, unlock, trunk, panic) and ensure the vehicle starts correctly.

- LOCK Button: Locks all vehicle doors.
- UN LOCK Button: Unlocks all vehicle doors.
- Trunk Release Button (Car Icon): Opens the vehicle's trunk or tailgate.
- Panic Button (Red Triangle): Activates the vehicle's alarm system. Press again to deactivate.
- Folding Mechanism Button (Small Silver Button): Press to release the key blade, allowing it to fold out. Press again to fold it back into the casing.
Maintenance
To ensure the longevity and proper function of your Acouto key fob shell, follow these maintenance guidelines:
- Keep Clean: Wipe the key fob with a soft, dry cloth to remove dust and grime. Avoid harsh chemicals or abrasive cleaners.
- Avoid Impact: Protect the key fob from drops or strong impacts, which can damage the casing or internal components.
- Protect from Moisture: While the shell offers some protection, it is not waterproof. Avoid exposing the key fob to excessive moisture.
- Battery Replacement: If your vehicle's remote functions become unreliable, the battery inside your transferred circuit board may need replacement. Refer to your vehicle's owner's manual for the correct battery type and replacement procedure.
Troubleshooting
If you encounter issues after installing the new key fob shell, consider the following:
Key Fob Not Functioning:
- Check Component Placement: Re-open the key fob shell and ensure the circuit board, transponder chip, and battery are correctly seated and oriented.
- Battery Check: Verify that the battery is correctly installed and has sufficient charge. Replace if necessary.
- Damage to Components: Inspect your original circuit board and transponder chip for any visible damage that might have occurred during transfer.
Key Blade Not Folding/Unfolding Smoothly:
